[Discuss] Another option for obtaining data

[mritd]

I'm new to prometheus, and I'm looking for solutions on how to get physical disk data from RAID cards.

So far I have found three options to get physical disk metrics data:

• perccli: Command line solution, it outputs plain text, not friendly to data parsing
• OMSA(Dell OpenManage Server Administrator): It works in theory, but I haven't been able to get it to work yet.
• LSI Storage Authority: This seems to be the best, it provides HTTP service and outputs json; however, it seems to require a simulated login.

Maybe try using LSI Storage Authority's HTTP API, I think it would be better;

Anyway, thanks for the work.

Hey @mritd, yeah this tool relies on the user installing perccli on the ESXi machine as a .vib, and then the exporter SSHs into the machine to run the command /opt/lsi/perccli/perccli /cALL show all J to gather the JSON, then exposes the information for Prometheus to scrape on /metrics.

So for your first point of perccli, you could use the <wherever-you-installed-perccli>/perccli /cALL show all J to have perccli print its output as JSON.

You can also specify a different path of where the perccli binary is called, by overriding the PERCCLI_FILE_PATH variable in the container/program. This could be useful if you aren't running the program against an ESXi machine.

Was this tool not working as expected for you?

Most of the data is perfect so far, but I can't seem to find a temperature indicator for the physical disks(It's possible I missed it.).

I'm trying to get through the LSI Storage Authority tool API to get it. Just some exploration of new tools 😆.
