How Does Application Observability Function?

Application observability tools or platforms function by observing the behavior of applications to ensure they perform appropriately. When deviations occur, these tools collect data to pinpoint the source of the issue, analyze its impact on business operations, and take corrective actions to prevent similar problems in the future.

Configuring an Application Observability Platform

When configuring an observability platform, three fundamental categories of data are considered:

  • Metrics: Quantified measures used to assess the status of specific processes. Changes in metrics often indicate underlying issues and are compared to defined baselines for analysis.
  • Traces: Complete processing records of requests, illustrating their journey through various network components and services. Traces contain numerous data points for error diagnosis, security threat detection, and network issue isolation.
  • Log Files: Automatically generated files containing information about user behavior and application events. Log files aid in root cause analysis, understanding metric changes, and identifying event origins.

Performance Management Integration

App observability is a part of broader performance management, where monitored data and analytics may not ensure optimal user experience. Performance management systems integrate monitoring data with automation and orchestration to autonomously remediate specific issues.

For instance, if an application's disk storage capacity runs low, performance management systems can use monitoring alerts and data to allocate additional storage automatically, mitigating potential performance or availability problems before they occur.
