Cloud-native systems are complex, but proper monitoring ensures they perform well, stay reliable, and minimise costs. Here are five key practices to manage performance effectively:
- Define KPIs and SLOs: Track metrics like CPU usage, latency, and error rates to set clear performance targets aligned with business goals.
- Implement Distributed Tracing: Map how microservices interact to quickly identify bottlenecks and improve troubleshooting.
- Centralise Telemetry: Combine metrics, logs, and traces into a unified platform for better visibility and faster issue resolution.
- Automate Monitoring and Alerts: Set up intelligent alerts tied to critical thresholds to detect problems instantly and avoid alert fatigue.
- Review and Update Regularly: Reassess your monitoring setup every few months to address gaps, adjust thresholds, and align with system changes.
These steps can cut downtime by up to 95%, improve response times, and reduce cloud costs by 30–50%. Tools like OpenTelemetry, Datadog, and Jaeger can help, but regular reviews and expert guidance ensure your monitoring evolves with your needs.

1. Define Key Performance Indicators and Service Level Objectives
To monitor cloud-native systems effectively, you need clear metrics and targets. Without well-defined KPIs and SLOs, it’s easy to collect a mountain of data that offers little insight into your system’s actual performance or health.
Key Performance Indicators (KPIs) are measurable metrics that provide a snapshot of how well your cloud-native applications are performing. These might include CPU usage, memory utilisation, request latency, error rates, and uptime. By tracking these metrics, teams can evaluate whether their applications are meeting business goals and delivering the user experience customers expect. KPIs also help identify issues early, enabling timely optimisation of resources.
When choosing KPIs, it’s crucial to align them with your business objectives. For instance, an e-commerce platform might prioritise transaction success rates, while a video streaming service would focus on reducing buffering. This requires collaboration between technical teams and business stakeholders to ensure the chosen metrics reflect both operational and strategic priorities.
Service Level Objectives (SLOs), on the other hand, are specific, measurable targets set for your KPIs. They define the acceptable performance levels for your services, such as 99.9% uptime
or response times under 200 milliseconds for 95% of requests.
These benchmarks are essential for gauging whether your applications meet the expected quality of service, which is critical for maintaining user trust and satisfaction.
To set effective SLOs, rely on historical performance data, user expectations, and business needs. Unrealistic targets - whether too lax or overly stringent - can cause problems. For example, overly strict SLOs may lead to unnecessary alerts and stress, while lenient ones may fail to push for meaningful improvements. Analysing past uptime and latency data can help establish achievable goals, while input from business leaders ensures these targets align with broader objectives.
Take, for example, a UK-based online banking platform. It might monitor transaction error rates, response times, and system availability, setting targets like 99.95% uptime and ensuring 95% of transactions are processed within one second. The table below illustrates how typical KPIs translate into SLOs and their business impact:
| KPI Example | Typical SLO Target | Business Impact |
|---|---|---|
| Uptime | 99.9% – 99.99% | Ensures reliability and trust |
| Average Response Time | <200ms – 2s | Enhances user experience |
| Error Rate | <0.1% | Reflects application quality |
| p95/p99 Latency | <500ms – 2s | Measures performance under load |
It’s easy to fall into common traps, such as tracking too many metrics, focusing on irrelevant KPIs, or setting unattainable SLOs. Avoid these pitfalls by prioritising metrics that directly affect user experience and business outcomes. Involve both technical and business teams in the process, and base your SLOs on real-world data rather than assumptions.
Keep in mind that KPIs and SLOs aren’t static. They should be reviewed and updated regularly, especially after major software updates, changes in user behaviour, or shifts in business strategy. This ensures your monitoring efforts remain aligned with evolving needs.
For organisations looking for expert guidance, consultancies like Hokstad Consulting specialise in DevOps, cloud infrastructure, and cost optimisation. They can help identify the most impactful KPIs, set achievable SLOs, and craft monitoring strategies that bridge technical performance with business goals.
2. Set Up Distributed Tracing Across Microservices
Distributed tracing takes operational insights beyond KPIs and SLOs, offering a detailed map of how services interact within your system. In cloud-native environments, where a single user request can pass through dozens of microservices, traditional monitoring tools often fall short. Distributed tracing fills this gap by tracking each request as it moves through your architecture, providing a clear view of service dependencies and pinpointing where issues arise.
Imagine a customer placing an order on your e-commerce platform. That single request might touch the authentication service, inventory checker, payment processor, shipping calculator, and notification system. Without distributed tracing, identifying which service causes a delay is like searching for a needle in a haystack. With it, you gain a full journey map
, showing exactly where bottlenecks occur.
For example, distributed tracing can quickly highlight performance issues. If traces reveal consistent database latency in your user profile service, engineers can focus their efforts on that specific area, cutting down the time needed to resolve issues.
OpenTelemetry has become the go-to standard for implementing distributed tracing. It provides vendor-neutral tools that work across multiple programming languages, ensuring flexibility. This means you’re not locked into a single provider and can switch tracing backends as your needs change.
To get started, instrument each microservice with tracing libraries that propagate trace context (trace IDs and span IDs) across service boundaries. Whether your system uses HTTP calls, gRPC, or message queues, proper context propagation is essential. Without it, traces can become fragmented, making troubleshooting much harder.
You’ll also need a centralised tracing backend to collect, store, and visualise the trace data. Options include open-source tools like Jaeger or Zipkin, or managed services such as AWS X-Ray, Google Cloud Trace, and Azure Monitor. Your choice will depend on your infrastructure and whether you prefer managing the system in-house or outsourcing it to a cloud provider.
By 2025, over 70% of organisations using cloud-native architectures are expected to adopt distributed tracing[7]. This shift underscores the growing need for complete visibility to maintain reliable and high-performing systems.
That said, implementing distributed tracing comes with challenges. Legacy systems may lack built-in tracing support, and the data collection overhead can grow significantly as your system scales. Using sampling strategies can help manage this. Instead of tracing every request, sampling 1-5% of traffic often provides enough data for effective troubleshooting without overwhelming storage or processing capacity.
Distributed tracing works hand-in-hand with metrics and logs, adding depth to your observability stack. For instance, if your alerting system detects high error rates, traces can pinpoint which service interactions are failing and why, offering immediate clarity.
For organisations looking to implement distributed tracing effectively, Hokstad Consulting provides expert guidance. Their DevOps expertise helps clients optimise cloud infrastructure, reduce operational costs, and establish robust monitoring strategies that leverage distributed tracing to improve system performance.
Modern platforms now integrate AI-powered analysis to accelerate issue detection. Combined with a centralised telemetry approach, AI-enhanced tracing strengthens operational efficiency and takes your system’s visibility to the next level.
3. Use Centralised Telemetry Collection
After discussing distributed tracing, the next logical step in achieving comprehensive monitoring is centralising your telemetry data. When dealing with multiple microservices, the sheer volume of data can become overwhelming. Centralised telemetry collection simplifies this by bringing together metrics, logs, and traces from across your distributed system into a single platform. This unified view not only reduces the hassle of switching between tools but also speeds up the troubleshooting process.
The benefits of this approach are particularly evident during incidents. Take, for example, a UK-based video streaming service that faced user complaints about slow load times. By using a centralised monitoring platform, the technical team was able to correlate latency metrics with error logs and traces. This pinpointed the root cause: an overloaded database query. With this insight, they quickly resolved the issue, minimising user disruption and ensuring they met their service level objectives [2].
To make the most of centralised telemetry, focus on three key data types:
- Metrics: These include CPU usage, memory consumption, and request latency, offering a snapshot of system performance.
- Logs: Detailed records of events and errors, providing context for specific issues.
- Traces: End-to-end views of request journeys across microservices, helping to identify bottlenecks or failures.
By correlating these data types, you can turn isolated observations into actionable system-wide insights. For instance, if an alert flags a spike in error rates, traces can help you identify which service interactions are failing, while logs provide the detailed context needed to resolve the issue.
Modern platforms such as Datadog, New Relic, Dynatrace, and AppDynamics are built around this unified approach. They offer centralised dashboards that combine metrics, logs, and traces, improving operational efficiency and reducing the time spent switching between tools. These platforms also integrate seamlessly with almost any component in your cloud-native stack, often without requiring additional custom development [5].
Adopting this strategy can significantly enhance your operations. Studies show it can reduce incident resolution times by up to 40% and cut downtime by 30% [5]. This is largely due to the elimination of manual data correlation and the inefficiencies of juggling multiple tools.
For organisations looking to avoid vendor lock-in, OpenTelemetry offers a vendor-neutral solution for centralised telemetry. It allows you to instrument your applications once and send data to any compatible backend. This flexibility ensures your monitoring setup can evolve alongside your needs without being tied to a single provider.
Cost management is another crucial factor to consider. Configure agents and exporters with data retention policies and filtering rules to avoid unnecessary expenses. For example, not every log message needs to be stored indefinitely. Many organisations adopt retention strategies that balance the need for visibility with cost control.
Security is equally important, especially for UK organisations handling sensitive customer data. Centralised platforms often include features like consistent data retention and deletion policies, audit trails, and role-based access controls. These capabilities help ensure compliance with data protection regulations while maintaining robust operational visibility [4].
For businesses in the UK looking to implement centralised telemetry effectively, Hokstad Consulting offers tailored solutions. Their expertise in cloud-native monitoring and DevOps can help organisations optimise performance, control costs, and stay compliant with local regulations.
The rise of AI-powered tools is further enhancing the value of centralised platforms. Features like anomaly detection and predictive alerting use machine learning to understand normal system behaviour and flag potential issues before they escalate [5]. Combined with the correlation capabilities of centralised data, this creates a solid foundation for maintaining high-performing cloud-native systems.

4. Set Up Automated Monitoring and Alerts
Building on the earlier discussion about centralised telemetry, the next step is implementing automated monitoring to detect issues within seconds. In fast-moving cloud-native environments, where services scale automatically and problems can arise at any time, manual monitoring simply can’t keep up. Automation ensures you’re always one step ahead, while setting the stage for smarter alert configurations.
For automated monitoring to be effective, it’s crucial to configure alerts intelligently. Instead of bombarding your team with unnecessary notifications, focus on alerts that are directly tied to your Service Level Objectives (SLOs). This way, your team only gets notified when thresholds critical to your system’s performance are breached, keeping distractions to a minimum [2][3].
Modern tools make this process much easier. Platforms like Datadog's Watchdog use AI to detect anomalies by learning your system’s usual behaviour, while Dynatrace's Davis AI goes even further, offering automatic root cause analysis when something goes wrong [5]. These tools help cut down on alert fatigue
by notifying you only when genuine issues arise, rather than every minor fluctuation.
To ensure comprehensive coverage, deploy monitoring agents that automatically gather key metrics and conduct regular API checks. These agents catch critical problems early and trigger immediate alerts, allowing your team to respond quickly. It’s also important to prioritise alerts by severity - distinguishing between major failures and minor glitches - and grouping similar alerts to avoid overwhelming your team with repetitive notifications.
Integrating alerting rules into your CI/CD pipeline is another must. This ensures that every new service or feature automatically includes monitoring, eliminating the risk of blind spots
where new deployments go live without adequate oversight. This approach keeps your monitoring systems aligned with your system’s evolution, from initial deployment to full-scale production.
For UK organisations, it’s essential to tailor escalation policies to local working hours, using the 24-hour clock and DD/MM/YYYY date format. On-call rotations should respect UK working patterns while maintaining 24/7 coverage for critical systems. This ensures smooth operations without overburdening your team.
Automated monitoring doesn’t just improve response times; it also reduces downtime and lowers incident costs. Many businesses find that these systems pay for themselves within months, thanks to fewer outages and faster resolutions.
For UK companies looking to refine their monitoring strategies, Hokstad Consulting offers tailored solutions, helping organisations optimise alerting systems while balancing cost efficiency and compliance [1]. Their expertise can be invaluable in streamlining operations and ensuring adherence to UK regulations.
When implementing automated monitoring, don’t overlook security considerations. Use audit trails and role-based access controls to safeguard sensitive data, particularly when handling customer information subject to UK GDPR requirements. Data retention policies should strike a balance between operational needs and regulatory demands, ensuring compliance without compromising functionality.
Finally, remember that automation isn’t a set it and forget it
solution. Regularly review your alert thresholds based on historical data and post-incident analyses. As your system evolves and traffic patterns shift, what worked initially may no longer be suitable. The goal is to maintain a balance between thorough monitoring and manageable alert volumes, keeping your team focused and your systems running smoothly.
5. Review and Update Monitoring Strategy Regularly
Even the most advanced monitoring systems can fall behind as your environment evolves. Regularly reviewing your monitoring strategy ensures it stays aligned with your current business goals and system architecture, helping you avoid costly blind spots that could disrupt operations.
Cloud-native environments are especially dynamic, with new microservices, shifting traffic patterns, and changing priorities. What worked six months ago might no longer catch critical issues today. In fact, data from 2024 shows that over 60% of cloud outages were caused by misconfigured or outdated monitoring systems [6]. This statistic underscores the importance of periodic evaluations to maintain system reliability.
Quarterly reviews have proven particularly effective. Organisations that assess their monitoring strategies every three months report a 30% reduction in mean time to resolution (MTTR) compared to those conducting annual reviews [5][6]. This regular cadence complements automated alerting systems, ensuring your monitoring evolves with your infrastructure.
When reviewing your strategy, focus on a few key areas. Reassess alert thresholds and service coverage, incorporating lessons learned from recent incidents. This helps eliminate outdated checks and ensures new components are properly monitored. Similarly, evaluate your dashboards - remove irrelevant metrics and include ones that reflect current business priorities.
Post-incident reviews are invaluable for refining your approach. Each outage or performance hiccup reveals areas where your monitoring may have fallen short. By documenting these gaps and addressing them systematically, you can turn setbacks into opportunities for stronger system resilience.
Technological advancements also necessitate regular updates. The increasing adoption of AI-driven anomaly detection and predictive alerts means tuning your monitoring setup to adapt to changing application behaviours [5].
Consider this example: in 2024, a major UK-based online retailer cut critical incident response times by 40% after introducing quarterly monitoring reviews. Their process included updating alert thresholds, adding checks for new payment processing microservices, and integrating insights from recent outages. The result? Better uptime and happier customers [6].
Integrating monitoring updates into your CI/CD pipeline can also make a big difference. By automating telemetry configuration during deployments, you minimise the risk of manual errors and ensure new features are monitored effectively [3].
Collaboration is key during these reviews. Involve both development and operations teams - developers bring insights into changes in application logic, while operations teams understand infrastructure evolution. This partnership ensures a more comprehensive review process [9].
Hokstad Consulting, for example, has helped many clients embed continuous monitoring reviews into their DevOps practices. Their approach not only enhances deployment cycles but also reduces cloud costs, ensuring that monitoring strategies support operational goals while staying financially efficient [1].
Finally, align these reviews with your cost-optimisation efforts. Regular audits can identify redundant metrics, refine data retention policies, and ensure you’re getting real value from your monitoring investments - an increasingly important factor as cloud expenses rise.
Stay ahead by keeping an eye on emerging monitoring technologies and industry trends. In a fast-moving cloud-native world, today’s cutting-edge tools can quickly become standard. Regular reviews help you assess new solutions and decide if they’re right for your environment.
Comparison Table
Selecting the right monitoring approach and understanding the distinctions between telemetry types are key to building a strong cloud-native performance strategy. The tables below outline these differences to help you make informed decisions.
Centralised vs Decentralised Monitoring Approaches
| Aspect | Centralised Monitoring | Decentralised Monitoring |
|---|---|---|
| Data Aggregation | Central platform consolidates all telemetry data | Distributed across teams and services |
| Visibility | Provides a complete view for cross-service correlation | Limited to individual services, with potential blind spots |
| Troubleshooting Speed | Faster root cause analysis due to consolidated data | Slower due to fragmented data sources |
| Alert Management | Consistent and standardised alerts across services | Inconsistent alerts, potentially missing cross-service issues |
| Team Autonomy | Limited flexibility with a standardised approach | High flexibility, allowing teams to choose their tools |
| Scalability | Simpler scalability with unified processes | Complexity increases with organisational growth |
| Single Point of Failure | Vulnerable if the central system fails | More resilient as local failures are isolated |
| Cost Structure | Higher upfront costs with potential savings over time | Lower initial costs but higher operational overheads |
| Compliance Reporting | Simplified through unified data sources | More challenging, requiring data aggregation from multiple sources |
Your organisation's specific needs will dictate the best approach. If unified visibility for compliance, incident response, or managing interconnected systems is a priority, centralised monitoring is ideal. On the other hand, decentralised monitoring is better suited for organisations with independent teams or diverse technology stacks [8].
Telemetry Types and Their Applications
Metrics, logs, and traces each serve a distinct role in observability. Knowing when to use them is essential for effective monitoring.
| Telemetry Type | What It Captures | Primary Use Cases | Best For | Example Tools |
|---|---|---|---|---|
| Metrics | Quantitative data (e.g. CPU usage, error rates, latency) | Real-time monitoring, alerting, capacity planning, trend analysis | Performance tracking, automated alerts, SLO monitoring | Prometheus, Datadog, CloudWatch |
| Logs | Timestamped event records and error messages | Debugging, auditing, security analysis, compliance | Root cause analysis, security, and compliance reporting | ELK Stack, Splunk, Fluentd |
| Traces | Request journeys across distributed services | Root cause analysis, identifying bottlenecks, mapping dependencies | Troubleshooting microservices and latency issues | Jaeger, OpenTelemetry, Zipkin |
These telemetry types complement one another: metrics highlight issues, logs provide detailed context, and traces pinpoint specific problem areas. Together, they enhance incident response and reduce resolution time [2][3]. Aligning your monitoring tools with your operational goals ensures a more effective strategy.
When evaluating total costs, consider factors like maintenance, compliance needs, and the savings enabled by quicker incident resolution. Hokstad Consulting often advises a hybrid approach, balancing centralised telemetry for core functions with decentralised monitoring for specialised workloads. This method supports both operational efficiency and business objectives, making it a practical choice for many organisations.

What challenges arise when implementing distributed tracing in legacy systems, and how can they be addressed?
Implementing distributed tracing in legacy systems comes with its fair share of hurdles. These older systems often feature monolithic architectures, lack built-in observability capabilities, and don’t adhere to modern, standardised protocols. This makes integrating contemporary tracing tools - primarily designed for microservices - a tricky task. Plus, legacy systems may not produce the telemetry data required for thorough tracing.
To tackle these issues, focus on identifying the most critical services first. Introduce lightweight tracing libraries selectively, ensuring minimal disruption. Another effective method is using proxy-based tools or middleware to collect trace data without making major code changes. Over time, modernising specific components and adopting open standards like OpenTelemetry can make the integration process smoother. Close collaboration between development and operations teams is crucial for a seamless roll-out and to boost system-wide visibility.
How does centralised telemetry collection help reduce downtime and speed up incident resolution in cloud-native environments?
Centralised telemetry collection is a cornerstone of managing cloud-native environments. It brings together metrics, logs, and traces from all services into a single, unified system. This consolidation makes it easier for teams to spot performance issues, detect anomalies, and identify the root cause of incidents without wading through scattered data.
