Confirmed support for customer metrics for versions from 1.0.0 to 1.4.x.
Micrometer is a simple application metrics facade for the JVM. It has become the defacto standard in the Java ecosystem and is integrated into SpringBoot. Read more on Micrometer at micrometer.io.
Instana supports Micrometer without any additional configuration. The sensor detects Micrometer usage and automatically collects metrics. No additional Maven dependency needed!
A Micrometer MeterRegistry is only discovered when a public method is called on the MeterRegistry object once the JVM is instrumented. Initializing a metric registry using a public constructor is usually the only public method executed before the Instana agent starts. Therefore, as soon as any MeterRegistry's public method gets called after the agent is started, the agent will be able to discover the registry.
All metric graphs will show up on the JVM dashboard.
We are gathering all types of metrics:
|Counter||The cumulative count since this counter was created|
|DistributionSummary||The total amount of all recorded events|
|FunctionCounter||The cumulative count since this counter was created|
|FunctionTimer||The total time of all occurrences of the timed event|
|Gauge||The current value|
|LongTaskTimer||The current number of tasks being executed|
|Timer||The total time of recorded events scaled to milliseconds|
|TimeGauge||The current value, scaled to the appropriate base unit|
Metric names contain concatenated tags in form of
Eg. in the following screenshot tags are:
exception=None, method=GET, outcome=SUCCESS, status=200, version=1.0, maintainer=instana
