URL: https://github.com/apache/ignite/pull/13362
Motivation
Prometheus does not support the JMX protocol natively; it only scrapes
metrics exposed over HTTP in its own text format. A bridge (JVM agent) is
required to make JVM-level metrics accessible to Prometheus.
This task integrates jmx_prometheus_javaagent into the ducktests
framework so that every server/client node exposes JVM memory and GC metrics at
:8083/metrics in Prometheus format. This enables Grafana
dashboards that mirror the jconsole "Memory" tab (heap, non-heap, memory
pools, GC collection count/time).
Changes
1. Dockerfile (modules/ducktests/tests/docker/Dockerfile)
- Download and install jmx_prometheus_javaagent-1.1.0.jar to
/opt/jmx_exporter.jar
2. jmx_exporter package
(modules/ducktests/tests/ignitetest/services/utils/jmx_exporter/)
- `{}init{}.py` — helper module with:
- JmxExporterParams — settings from globals config (enabled, port)
- get_jmx_exporter_params() — parse globals
- is_jmx_exporter_enabled() — check if enabled
- get_jmx_exporter_yml_content() — read bundled YAML content
- jmx_agent_jvm_opt() — build -javaagent JVM option string
- `jmx_exporter.yml` — rule mappings for JVM memory and GC metrics:
- jvm_memory_heap_bytes_{used,max,committed,init}
- jvm_memory_nonheap_bytes_{used,max,committed,init}
- jvm_memory_pool_usage_bytes{pool,attribute}
- jvm_memory_pool_collection_bytes{pool,attribute}
- jvm_gc_collection_count_total{gc}
- jvm_gc_collection_time_seconds_total{gc}
3. ignite_spec.py
(modules/ducktests/tests/ignitetest/services/utils/ignite_spec.py)
- In __get_default_jvm_opts(): append
-javaagent:/opt/jmx_exporter.jar={port}:{config_dir}/jmx_exporter.yml when
jmx_exporter.enabled is true in globals
4. ignite_aware.py
(modules/ducktests/tests/ignitetest/services/utils/ignite_aware.py)
- In init_persistent(): download jmx_exporter.jar to node if not
present (idempotent: test -f || curl)
- In _prepare_configs(): create jmx_exporter.yml in the node's config
directory from bundled resource
