[//]: # (werk v2) # ibm storwize: Fix missing data when monitoring nodes key | value ---------- | --- compatible | yes version | 2.3.0b1 date | 2024-01-03T09:05:20+00:00 level | 1 class | fix component | checks edition | cre lsnodestats command was used for monitoring nodes in IBM Storwize devices. Storwize devices don't have the lsnodestats command which led to missing data in ibm_svc_nodestats services. Now, the IBM SVC agent uses the lsnodestats if it's available and lsnodecanisterstats otherwise.
