Stupid Question

Definitely not a stupid question.

 

Yes, the management pack can raise notifications when a pool member goes down. The health state of the pool member will change to signify its changed state and the reason. Also, the pool and any associated objects will be marked as unhealthy if the Big-IP is marked as such also ~ e.g. pool marked down by child pool member, or the reverse.

 

The management pack can also raise notifications for more granular performance-based health. For example, if you decide that 0 total connections on a pool member is unexpected and undesirable, you can create a threshold trigger which will mark the pool member unhealthy when its total connections is 0 or some low number. The threshold will change to red when the connections goes to 0, and return to green when it rises above the threshold.

 

You can use the built-in Health Explorer in the UI Console (Opsmgr) or PowerShell to identify and handle health state changes.

 

Thanks for your question, and let us know if you'd like help setting up overrides or reviewing health state.

I dont suppose you could give me a pointer as to where to look in creating a monitor to monitor the state of a pool and its members.

 

 

I would like to raise an alert when a pool member is marked offline and then clear the alert when it comes back on line. - but im struggling to see where to target anything or where to create overrides.

Hello David,

 

 

The F5 Management Pack includes built-in monitors for the health of all objects, including pool members, pools, and virtual servers. You can use the SCOM GUI to create recovery or alert actions based on the existing monitors.

 

 

For an example of creating an alert for a specific pool member:

 

1) Find the pool member you want to monitor in the SCOM Diagram View (LTM)

 

2) Right click on the pool member

 

3) Select "Health Explorer"

 

4) Right click on "Entity Health"

 

5) Select "Monitor Properties"

 

6) Select the "Overrides" tab

 

7) Press the "Override button"

 

8) You can then select this Pool Member instance, a group of Pool Members, or ALL Pool Members

 

9) In the "Override" wizard, you can specify what part of the alert to override/enable and recovery actions

 

 

Let me know if I can provide more information.

 

 

Thanks,

 

Stephen (F5)

I've done that and managed to trigger an alert based on entity state change, However what I really want to do is have a monitor / alert that shows in the console for "Pool Member 192.168.1.1 Marked Down" or similar, and then when the pool member comes back up, clear the alert.

 

 

Dear Freinds, I have installed the management pack and have also set up the monitor to monitor thr status of Poll members and I am getting alerts too , but in the alerts I would like to get the information like who has taken the pool member down , can some one help me in this..
