SCOM: SP1 Edition of the Cisco Management Pack , v22.214.171.124
September 26, 2009 19 Comments
I have completed the first version of the Cisco Management Pack for SP1 compatibility. The monitoring in the management pack is identical to the R2 version of the MP, described most recently here. Due to the dependence on the WMI SNMP provider for object discovery, there are inevitably some scalability limitations intrinsic to the SP1 edition of this MP, but I haven’t done enough full-scale testing to ascertain those limitations as of yet. Additionally, deployment of this management pack requires some additional steps. These steps are detailed below (taken from the MP documentation):
This management pack utilizes the WMI SNMP provider to perform discovery of SNMP objects. In order to use this management pack, the following steps must be completed on each server that will function as a proxy agent for SNMP-monitored Cisco devices.
Install the SNMP protocol and WMI SNMP provider
- To install these components, access Add/Remove Programs in the Control Panel, and select Add/Remove Windows Components. Under Management and Monitoring select: Simple Network Management Protocol and WMI SNMP Provider
The following MIBs must be exported to MOF files with smi2smir.exe and imported with MOFComp.exe: CISCO-ENVMON-MIB and CISCO-MEMORY-POOL-MIB.
- The MIBs and a batch file to perform these steps can be found in the /Setup directory included with this MP distribution. Run the RegCiscoMibs.cmd file and check the output log: register.log to confirm that the mibs were successfully compiled and imported.
Recommended Proxy Agent Configuration
If WMI receives too many requests in a short time, it may suspend processing of requests for a period of time. This can impact the ability of this management pack to discover Cisco SNMP objects in a timely fashion (WMI SNMP is only used by this MP for discovery, and not object monitoring). In order to minimize the chances of this situation occurring, the object discoveries in this MP should not be scheduled too aggressively. Additionally, it is recommended that if a large number of Cisco SNMP devices are to be monitored, they should be distributed across multiple proxy agents for load-balancing of the WMI SNMP requests.
It is highly recommended that all agents that will function as proxy agents for SNMP devices have the Windows Script Host version 5.7 installed. Version 5.7 is far more efficient than previous versions and reduces the resource utilization by the cscript.exe process dramatically.
It is also highly recommended that all agents that will function as proxy agents for SNMP devices have the hotfix: KB96163 applied. This hotfix resolves instability with SNMP monitoring in Operations Manager 2007 SP1. http://support.microsoft.com/default.aspx/kb/961363
I’m interested to hear how this SP1 edition of the Cisco Management Pack functions in different environments, so any feedback is most certainl welcome. I will continue to post updates to this site so be sure to check back regularly. For more information about the scripts utilized in discoveries in this edition of the MP, this post should sum it up.
