search-insights

Collect raw metrics and diagnostics information from a search Cluster for insights (visualization, analytics and audits)

Building

mvn clean compile assembly:single

Running

Syntax:

./search-insights-collector.sh -n <clustername> [--collect-host-metrics | --collect-zk-metrics | --collect-solr-metrics | --zkhost <zkhost> | -d <comma separated list of Solr hosts>]

Examples:

  • ./search-insights-collector.sh -n myprodcluster.us-east-1 --collect-host-metrics --collect-zk-metrics --collect-solr-metrics --zkhost myzookeeperhost1:2181
  • ./search-insights-collector.sh -n myprodcluster.us-east-1 --collect-solr-metrics -d http://solr1:8983/solr,http://solr2:8983/solr

Notes:

  • clustername (or -n) is a required parameter. The generated file contains the cluster name in prefix. The name shouldn't contain spaces or special characters (other than '-').
  • --zkhost parameter is necessary if using --collect-zk-metrics
  • To supply Solr URLs directly, use -d parameter. If not specified, Solr URLs will be looked up in live_nodes of ZooKeeper (if --zkhost is specified)
  • To disable collection of logs and field metrics (Luke), you can add --disable-expensive-operations parameter
  • If you have additional metadata, e.g. datacenter name, availability zone etc., pass them using -k datacenter=dc1,az=abc.

Authenticated Solr Clusters:

If your Solr cluster is protected with Basic Authentication, then export the username and password to access the Solr cluster to the following environemnt variables before executing the collector: INSIGHTS_COLLECTOR_USERNAME and INSIGHTS_COLLECTOR_PASSWORD.

Example:

export INSIGHTS_COLLECTOR_USERNAME=hello
export INSIGHTS_COLLECTOR_PASSWORD=world

Outputs

  • Output will be available in archives/ directory.
