Hands-On Microservices with Kotlin

Metrics endpoint

The metrics endpoint available in the URL http://localhost:8080/actuator/metrics/ provides statistics on our microservice. If we invoke this URL, we can see the following names; each of them will be a metric that we can use to get more information on:

{  "names": [    "jvm.buffer.memory.used",    "jvm.memory.used",    "jvm.buffer.count",    "logback.events",    "process.uptime",    "jvm.memory.committed",    "jvm.buffer.total.capacity",    "jvm.memory.max",    "system.cpu.count",    "process.start.time"  ]}

If we like to get details on the JVM memory used, we can use the URL http://localhost:8080/actuator/metrics/jvm.memory.used:

{  "name": "jvm.memory.used",  "measurements": [    {      "statistic": "Value",      "value": 195595240    }  ],  "availableTags": [    { "tag": "area", ...
