than disable Performance Analyzer

If you prefer to save memory and run your local instance of OpenSearch with the Performance Analyzer plugin disabled, perform the following steps:

1. Before disabling Performance Analyzer, stop any currently running RCA agent action by using the following command:

  curl -XPOST localhost:9200/_plugins/_performanceanalyzer/rca/cluster/config -H 'Content-Type: application/json' -d '{"enabled": false}'

1. Shut down the Performance Analyzer RCA agent by running the following command:

  kill $(ps aux | grep -i 'PerformanceAnalyzerApp' | grep -v grep | awk '{print $2}')

1. Disable the Performance Analyzer plugin by running the following command:

  curl -XPOST localhost:9200/_plugins/_performanceanalyzer/cluster/config -H 'Content-Type: application/json' -d '{"enabled": false}'

example : curl -XPOST -k -u admin:password https://localhost:9200/_plugins/_performanceanalyzer/cluster/config -H ‘Content-Type: application/json’ -d ‘{“enabled”: false}’

1. Uninstall the Performance Analyzer plugin by running the following command:

  bin/opensearch-plugin remove opensearch-performance-analyzer
