Monitoring Unisphere Central for SC Series about checkmk_dell_storage HOT 5 CLOSED

Hi @jayscovill

I use it with Unisphere Central/Enterprise Manager but not yet in version 20. And we have a SC5020 integrated as well. So this should work if it is not a version incompatibility. The special agent reports that it only made 2 requests to the api. This should be the login and then get the list of storage centers. If the List of storage centers is empty this would explain this behavior. If you login with the same user in the web interface of the (https://unisphere.domain.com:3033/ui/storage/storageCenters) do you get a list of storage centers?

Hi,

Ok, I realize that the first problem here is that I didn't have a Storage Center mapped to the user I created for monitoring (Reporter access).

Now that I've mapped a Storage Center to it the connection test does query the list and returns the list of services such as controllers, etc. However when I do a full services scan it's still only showing the state of the API but no other services.

So it looks like I'm still doing something wrong.

Hi @jayscovill

Not comes the piggyback magic. The server with the Unisphere Central only gets the one check reporting if the agent is running correctly. The other checks get assigned to other hosts. You either need to create these hosts manually or use the dynamic host configuration https://docs.checkmk.com/latest/en/dcd.html feature. In the agent output you find all the hosts getting piggyback data as <<<<NAME>>>> lines.

Ok, I do have the Storage Center for the SAN set up as a host as I'm currently monitoring it via SNMP. And the Agent data being returned during the connection test for the Unisphere Central host is listing the SAN Storage Center host.

If I'm understanding the piggyback mechanism correctly if I have the SAN storage center added as a host with the same name that is being returned by the agent it should automatically add the data to the SAN storage center? That's not happening or nor is it if I force the piggyback option on the SAN host entry. But I'm very new to CheckMK so my understanding could be flawed.

I noticed that the agent for the Unisphere Central is returning:

Version: 20.1.1.716
AgentOS: EnterpriseManager
sandomaincom
<<<dell_storage_center:sep(59)>>>
san.domain.com;Up;;Sc5000Series;7.4.21.4;G7M08B3;369598;0;2;38;0;49;0;5;7
<<<dell_storage_controller:sep(59)>>>
Bottom Controller;Up;;2021-04-18T08:50:39-04:00;False;Sc5020;7.4.21.4;G7M08B3;352-887-429-27;369599

Could it be that the piggyback data is trying to match "sandomaincom" with a valid host when the actual hostname is san.domain.com? Is it just a matter of doing a hostname translation for piggyback hosts to match "sandomaincom" to "san.domain.com"?

Edit: Yep! That did the trick! I'm good to go. Thanks for your excellent help!
