Zookeeper

This page describes adding a Zookeeper to the Lenses Agent.

Set the following examples in provisioning.yaml

Simple configuration, without metrics

zookeeper:
- name: Zookeeper
  version: 1
  tags: ["tag1"]
  configuration:
    zookeeperUrls:
      value:
        - my-zookeeper-host-0:2181
        - my-zookeeper-host-1:3181
        - my-zookeeper-host-2:4181
    # optional, a suffix to Zookeeper's connection string
    zookeeperChrootPath: 
      value: "/mypath" 
    zookeeperSessionTimeout: 
      value: 10000 # in milliseconds
    zookeeperConnectionTimeout: 
      value: 10000 # in milliseconds

Simple configuration, with JMX metrics

Simple configuration with Zookeeper metrics read via JMX.

zookeeper:    
- name: Zookeeper
  version: 1
  tags: ["tag1"]
  configuration:
    zookeeperUrls:
      value:
        - my-zookeeper-host-0:2181
        - my-zookeeper-host-1:3181
        - my-zookeeper-host-2:4181
    # optional, a suffix to Zookeeper's connection string
    zookeeperChrootPath: 
      value: "/mypath" 
    zookeeperSessionTimeout: 
      value: 10000 # in milliseconds
    zookeeperConnectionTimeout: 
      value: 10000 # in milliseconds
    # all metrics properties are optional
    metricsPort: 
      value: 9581
    metricsType: 
      value: JMX
    metricsSsl: 
      value: false

With such a configuration, Lenses will use 3 Zookeeper nodes and will try to read their metrics from following URLs (notice the same port - 9581 - used for all of them, as defined by metricsPort property):

my-zookeeper-host-0:9581
my-zookeeper-host-1:9581
my-zookeeper-host-2:9581
