Does performance analyzer agent start automatically?

Hi team,

I can start Elasticsearch + Open Distro cluster but I cannot see the performance analyzer agent process on my host.

Do I need to start the agent manually?
(/usr/share/eleasticsearch/plugins/opendistro_performance_analyzer/pa_bin/performance-analyzer-agent)
If yes, how to start the agent?

Or

Does the agent start automatically?

Regards,
Worapoj
