Performance Monitoring
La performance monitoring tool colecciona métricas de GPFS y provee información de performance del sistema. Está habilitada por default e incluye Collectors, Sensors y Proxies.
Collector
Un collector soporta hasta 150 sensor nodes. Con un collector debería ser suficiente para nuestro sistema. Se pueden armar esquemas con más de un collector (multi-collector federation) por razones de escala y de tolerancia a fallas.
Podemos utilizar mmgt01 como Node Collector en el cluster de storage y vlmgt02 en el cluster cliente, ya que es buena práctica mantener servicios extra (como monitoreo) fuera de los quorum nodes.
Sensors
El componente que recopila datos de performance de un nodo
Proxy
Se corre un proxy por cada protocolo para recopilar métricas de ese protocolo.
IBM Storage Scale bridge for Grafana
Queremos incorporar IBM Storage Scale bridge for Grafana para poder ver métricas de performance de GPFS en Grafana.
Para eso necesitamos configurar la performance monitoring tool de GPFS.
Configurar performance monitoring tool
Necesitamos los paquetes gpfs.gss.pmsensors gpfs.gss.pmscollectors
Los encontramos únicamente en el storage node.

This is an asynchronous process.

CherryPy
En el nodo collector tiene que estar instalado el paquete de python CherryPy.
[root@vlmgt02 gpfs_perf_testing]# python -m venv env [root@vlmgt02 gpfs_perf_testing]# source env/bin/activate (env) [root@vlmgt02 gpfs_perf_testing]# pip install cherrypy
