Monitoring CentOS in SCOM 2012

I needed to setup monitoring of a CentOS Linux server in SCOM 2012 R2.

Kevin Holman has a full write up on how to install Unix/Linux Agents on SCOM 2012 here: Link

I am going to focus specifically on my experience with CentOS using the New Universal Linux Agents and Management Packs.

First I did a discovery using the IP address.

It fails telling me that my Linux server is not in DNS.

I ping the server to verify it exists in DNS.

I do a reverse lookup on the IP Address using NSLookup and it’s not found.

image

To fix this I go to Active Directory DNS and add the Pointer to the Reverse Lookup Zone.

I do another NSLookup  and its now working.

Now I try to discover the Linux Server in SCOM and get an error of Unsupported OS.

I look in the catalog and these are specifically for SCOM 2007 R2 and will not work with SCOM 2012.

I need the new Universal Unix / Linux Management Packs as CentOS doesn’t have its own MPs.

For SCOM 2012 RTM and SP1 I browse out to the web. http://www.microsoft.com/en-us/download/details.aspx?id=29696

For SCOM 2012 R2 I go to the Installation media d:\Management Packs.

With the new Universal MPs installed the discovery process works.

But I click manage and the Agent Fails Sad smile

The details say

Agent deployment operation was not successful

Failed to copy kit. Exit code: -1073479144
Standard Output:
Standard Error:
Exception Message: An exception (-1073479144) caused the SSH command to fail –

I check the Wiki for this error http://social.technet.microsoft.com/wiki/contents/articles/4966.troubleshooting-unixlinux-agent-discovery-in-system-center-2012-operations-manager.aspx

I couldn’t find a solution so I browse out to C:\Program Files\Microsoft System Center 2012 R2\Operations Manager\Server\AgentManagement\UnixAgents\DownloadedKits  on the Management Server and use WinSCP to copy the file over to the /tmp directory on the CentOS server and install it manually using this command

rpm -ihv scx-1.5.0-128.universalr.1.x64.rpm

image

The manual install works ok but throws a security warning.  This is just a test server so I am going to ignore it.  I go back to SCOM and try to discover it.  I get a new message that it needs to Sign certificate and manage computer instance.   Sounds good to me.

image

I click Ok and the Wizard completes.

I open the SCOM Console Linux Server State view and the server shows up Healthy.
