Refresh the IBM Spectrum Scale meta data used by the IBM Spectrum Scale Performance Monitoring Bridge for Grafana

Grafana bridge running in a classic scale environment:

1. Verify grafana-bridge process is running

   Command:

   ps -ef |grep Grafana

   Example output:

   [root@scale-11 ~]# ps -ef |grep Grafana
   root      391458       1  0 10:35 ?        00:03:51 python3 zimonGrafanaIntf.py -c 10
   root      626718  626648  0 18:28 pts/0    00:00:00 grep --color=auto Grafana

2. Get scale_grafana apikey value

   Command:

   KEYVALUE=$(mmperfmon config show --apikey scale_grafana |jq '.key')

   Example output:

   [root@scale-11 ~]# KEYVALUE=$(mmperfmon config show --apikey scale_grafana |jq '.key')
   [root@scale-11 ~]# echo $KEYVALUE
   "3e651f67-cd9c-443e-9ce1-84621763e557"

3. Send metadata update request to a grafana-bridge process via REST API

   Command:

   curl http://localhost:4242/api/update -u scale_grafana:$KEYVALUE

   Example output:

   [root@scale-11 ~]# curl http://localhost:4242/api/update -u scale_grafana:$KEYVALUE
   {"msg": "Successfully retrieved MetaData"}

Grafana bridge running in a CNSA cluster:

1. Get grafanaBridge pod names

   Command:

   oc get po -o wide -n ibm-spectrum-scale |grep grafana

   Example output:

   [[email protected] ~]# oc get po -o wide -n ibm-spectrum-scale |grep grafana
   ibm-spectrum-scale-grafana-bridge-699fb97c58-9wqtt   1/1     Running   0   4d8h    10.254.20.31   worker1.helene.cp.fyre.ibm.com   <none>  <none>
   ibm-spectrum-scale-grafana-bridge-699fb97c58-jrs4z   1/1     Running   0   4d8h    10.254.15.211  worker0.helene.cp.fyre.ibm.com   <none>  <none>

2. Send metadata update request to a grafana-bridge process in each pod via REST API

   Command:

   curl https://localhost:8443/api/update -u scale_grafana:`cat /etc/perfmon-api-keys/scale_grafana` -k

   Example output:

   [[email protected] ~]# oc rsh ibm-spectrum-scale-grafana-bridge-699fb97c58-9wqtt
   Defaulted container "grafanabridge" out of: grafanabridge, initservice (init)

   {"msg": "Successfully retrieved MetaData"}
   sh-4.4$ exit
