HBase 1.x

Hbase 1.x using prometheus jmx eporter

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:
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"

- pattern: .+
  • prometheus scrape targets:
yaml 
# 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
