Resource Pool for Network Device Monitoring

    Question

  • Hi All,

    I know there have been a bunch of discussions on resource pools for network device monitoring, but;

    'Considerations when Designing a Management Group for Network Monitoring' states, "Network monitoring in System Center 2012 – Operations Manager requires its own separate resource pool." I know network device monitoring will work using a resource pool also shared by agents, the 'all management servers pool' for example, so I'm wondering where the implied requirement for a dedicated resource pool stems from? Using a non-dedicated resource pool doesn't seem to prevent network device monitoring from working, so is it just for scaling?

    What I'm getting at really is; in the scenario where we have three management servers, do I really need to stand up another two (for resilience) just for monitoring circa 250 network devices, or can I just ensure that the three existing management servers are sufficiently resourced and used those? 

    Thanks.

  • Hi, from design and planning guide

    "Performance and Scale

    Because network monitoring workflows run on management servers (on the SNMP module), and not on agents, a heavy load is placed on the management servers.  Therefore for better performance we recommend using dedicated management servers in dedicated resource pools for network monitoring."

    it's just recommended to use dedicated resource pool, but if you don't experience any performance issues and have no additional resources for two additional MS you can monitor agents and network devices from the same resource pool.

  • You are right, you need rediscover with a different resource pool

  • Thanks for the info Alexis.

    If we use a single resource pool for all monitoring, then find at a later date that we need to separate out the network device monitoring, how achievable is this retrospectively? Is it a case of re-running discovery with a different resource pool configured? I guess this could be quite involved if we have several hundred network devices being monitored.
