We use HostMon agent on AIX to capture stats on disk on the deploy servers.
I see the HostMon agents in Agent Overview but can only go back 72h to look at stats.
When I look under Infrastructure, the HostMon agent doesn't show up. Why?
I was hoping that the HostMon agent would store stats in performance warehouse and that I could go back to 365 Days history.
To get the information from the performance warehouse, plot/add a dashboard > use for analysis > chart > add series and pick the Disk Storage Utilization measure.
You can further splitting on disk/file system and agent host level.
