Monitoring Intel VROC with rstcli

Checkmk Exchange
1

Hello!

I’m trying to monitor a windows machine with a vroc-raid from intel. (Virtual RAID on CPU)
I have two “controllers” activated. The VROC for NVME and the origine RST SATA Controller.

I modified the check_mk_agent-plugin (rstcli.bat) to match IntelVROCCli.exe.

The service-discovery for this plugin is working for the NVME-Volume. The other Volumes doesnt appear.
I couldn’t figure out the difference. There are no interesting “ifs” in the sourcecode for this check plugin.

Anybody a hint for me to look out?

Here the output of rstcli:

<<<rstcli:sep(58)>>>

@beli3005 looks like there is a bug in the parse function of rstcli check plugin.

 95 def parse_rstcli(info):
 96     if info == [["rstcli not found"]]:
 97         return {}
 98 
 99     rstcli_sections = parse_rstcli_sections(info)
100     if rstcli_sections is None:
101         return {}
102 
103     volumes = {}
104     for section in rstcli_sections:
105         if section[0] == "VOLUME INFORMATION":
106             volumes.update(parse_rstcli_volumes(section[1]))
107         elif section[0].startswith("DISKS IN VOLUME"):
108             volume = section[0].split(":")[1].strip()
109             volumes[volume]["Disks"] = parse_rstcli_disks(section[1])
110         else:
111             raise MKGeneralException("invalid section in rstcli output: %s" % section[0])
112 
113     return volumes

line 106

106             volumes = parse_rstcli_volumes(section[1])

needs to be changed to

106             volumes.update(parse_rstcli_volumes(section[1]))

after tis change the check will discover three volumes with two disks each

you nailed it

great appreciation

Thanks!

Hi! So glad I found this thread, had the same result with more than one volume.
Changed like @thl-cmk wrote, worked instantly.

THANK YOU!

Will this fix ever get into the main updates? We have to apply it after every cmk update manually.
