Description
Describe the bug
We use external libraries from OTel to create these metrics and it turns out most of them don't work with native mode.
This this will require a lot of work to fix and should be made in the scope of a new issue.
Most likely we will need to either contribute fixes to upstream or instrument ourselves.
This the current compatibility matrix:
Metric Name | Description | Type | Available on JVM? | Available on Native? | MP 2.0? |
---|---|---|---|---|---|
http.server.request.duration | Duration of HTTP server requests | HISTOGRAM | Y | Y | Y |
jvm.memory.committed | Measure of memory committed | LONG_SUM | Y | No data produced | Y |
jvm.memory.used | Measure of memory used | LONG_SUM | Y | No data produced | Y |
jvm.memory.limit | Measure of max obtainable memory | LONG_SUM | Y | Not present | Y |
jvm.memory.used_after_last_gc | Measure of memory used, as measured after the most recent garbage collection event on this pool. | LONG_SUM | Y | No data produced | Y |
jvm.gc.duration | Duration of JVM garbage collection actions | HISTOGRAM | Y | Not present | Y |
jvm.class.count | Number of classes currently loaded. | LONG_SUM | Y | No data produced | Y |
jvm.class.loaded | Number of classes loaded since JVM start. | LONG_SUM | Y | No data produced | Y |
jvm.class.unloaded | Number of classes unloaded since JVM start. | LONG_SUM | Y | No data produced | Y |
jvm.cpu.count | Number of processors available to the Java virtual machine. | LONG_SUM | Y | Y | N |
jvm.cpu.limit | LONG_SUM | Y | No data produced | N | |
jvm.cpu.time | CPU time used by the process as reported by the JVM. | DOUBLE_SUM | Y | Not present | N |
jvm.system.cpu.utilization | CPU time used by the process as reported by the JVM. | DOUBLE_SUM | Not present | No data produced | N |
jvm.cpu.recent_utilization | Recent CPU utilization for the process as reported by the JVM. | DOUBLE_GAUGE | Y | No data produced | N |
jvm.cpu.longlock | Long lock times | HISTOGRAM | Y | Y | N |
jvm.cpu.context_switch | DOUBLE_SUM | Y | No data produced | N | |
jvm.network.io | Network read/write bytes. | HISTOGRAM | Y | Not present | N |
jvm.network.time | Network read/write duration. | HISTOGRAM | Y | Not present | N |
jvm.thread.count | Number of executing platform threads. | LONG_SUM | Y | Y | Y |
Expected behavior
Most metrics, especially the MP 2.0 related ones, should be available on native mode.
Actual behavior
See table in the description.
