How to filter Spring boot actuator metrics?

Question

Spring boot actuator metrics (/actuator/metrics) comes with many default metrics. Some of them are:

"jvm.memory.max",
"jvm.threads.states",
"process.files.max",
"jvm.gc.memory.promoted",
"tomcat.servlet.error",
"system.load.average.1m",
"jvm.memory.used",
"jvm.gc.max.data.size",
"jvm.memory.committed",
"http.server.requests",
"system.cpu.count",
"logback.events",
"tomcat.global.sent",
...

Is it possible to expose only few of them? (i.e. filtering them or better yet, telling Spring boot not to collect them at all?)

Answer 1

You can use management.metrics.enable.* properties to control the metrics that are enabled and bound to the meter registry. Where a metric's name is . separated, you can disable multiple metrics with a single property. For example, to disable all jvm properties you can use the following property:

management.metrics.enable.jvm=false

Where there are multiple properties that match the same metric, the most-specific wins. For example, to disable all jvm metrics other than jvm.memory.max, you can use the following properties:

management.metrics.enable.jvm=false
management.metrics.enable.jvm.memory.max=true

You can use all to match all metrics. For example, to disable all metrics other than jvm.memory metrics, you can use the following properties:

management.metrics.enable.all=false
management.metrics.enable.jvm.memory=true
