About

Initial test example. Not everything is rendered or usable. Some metrics are wrong, because this is quick copy/adaptation of my other dashboard used with HBase 2.x

Tested with

HBase:

• prometheus v2.19.0
• grafana v7.1.1 (3039f9c3bd)) with prometheus as Data Source
• Hadoop 2.7.1
• hbase 1.1.13 with jmx_prometheus_javaagent-0.13.1-SNAPSHOT.jar (just download form github and compile it on your own)

HBase Master HBASE_OPTS appended:

-javaagent:/data/jmx_exporter/jmx_prometheus_javaagent-0.13.1-SNAPSHOT.jar=0.0.0.0:26010:/data/jmx_exporter/jmx_hbase.yaml

HBase Regionserver HBASE_OPTS appended:

-javaagent:/data/jmx_exporter/jmx_prometheus_javaagent-0.13.1-SNAPSHOT.jar=0.0.0.0:26030:/data/jmx_exporter/jmx_hbase.yaml

• jmx-prometheus config /data/jmx_exporter/jmx_hbase.yaml:

---
lowercaseOutputName: true
lowercaseOutputLabelNames: true
rules:
- pattern: Hadoop<service=HBase, name=RegionServer, sub=Regions><>Namespace_([^\W_]+)_table_([^\W_]+)_region_([^\W_]+)_metric_(\w+)
  name: HBase_metric_$4
  labels:
    namespace: "$1"
    table: "$2"
    region: "$3"
- pattern: Hadoop<service=(\w+), name=(\w+), sub=(\w+)><>([\w._]+)
  name: hadoop_$1_$4
  labels:
    "name": "$2"
    "sub": "$3"
- pattern: .+

• prometheus scrape targets:

# two hbase masters
  - targets:
    - m-1:26010
    - m-2:26010
    labels:
      type: master
# three hbase regionservers
  - targets:
    - m-1:26030
    - m-2:26030
    - m-3:26030
    labels:
      type: regionserver

Known limitations

• some metrics are empty because they are remnants from HBase 2.x and they just don't exist (I was lazy)
• You may need to adjust dashboard to match your prometheus labels
• Vast majority of metrics is not yet exposed on the graphs, but you can add them on your own
• Some metrics are duplicated because the way they are exposed by jmx_exporter
