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.
