False SIM "System is unreachable" messages

False SIM "System is unreachable" messages

I'm running SIM 4.2 and am getting many false "System is unreachable" message. When I see one of these messages, I ping the device and the device answers. After an interval, SIM sends a "System is recheaable message."

I've been modifying the timeout and retry values, but I don't think they are working correctly. It seems to me that SIM is ignoring the values I type in.

I updated from SIM 4.0 to 4.2. I had this feature turned off since I couldn't get it to work as I expected.

Can someone explain to me how all of the following configuration screens ipmact the "system is unreachable" message and which one I should change?

I'm only concerned with ICMP ping responses and I would like 2 retries with a 10 second timeout (unless someone can recommend something more reasonable).


Options->Global Protocol Settings (10 second timeout-2 retries)
Options->System Protocol Settings (I ran this job with ALL SYSTEMS)

LOGS->All scheduled Tasks
Hardware Status Polling (for servers and nonservers)
Step 2 Select Protocol Setting (I selected only ICMP)
Time & Retires (have something different than my defaut values) timeout -- use default (currently "4" -- I have no idea where this came from)
reries -- use custom - 2

If I go to a specific device
System Page -> Links -> System Protocol Settings, I see that it says Use Global Defaults. However, the "Ping" Setting is dimmed out and the time is 5 and retries is 0. I'm wondering if it's somehow defaulting to this setting.

Change the Server to NOT use the Global Ping & if reqd. SNMP Parameters. And then configure the specific Ping and SNMP Parameters.

It seems the Global Parameters were being ignored in some cases. There was something earlier in the Forums about it.

I changed the time & retries in the hardware status polling tasks (step 2) to use the custom settings and it didn't resolve my problems.

Is that what you're suggesting?

Re: False SIM "System is unreachable" messages

In regards to 4.2, which MIB contains the "Unreachable" and "Reachable" snmp trap messages? I was able find/modify the MIB in 4.1 but cannot find it in 4.2 = basically, I want SIM to page when the system is unreachable and reachable, 4.2 only pages when it's unreachable.

I've gone through all the 4.2 MIBS and cannot find this trape - if anyone knows how to change the snmp trap "system is reachable" from Normal to Major status, let us know how you did it.

Re: False SIM "System is unreachable" messages

Since I've upgraded to 4.2, I seem to be getting a lot of alerts for systems unreachable when the system is actually up and running. Over the weekend I had over 500 emails. My Hardware status polling task for servers is as follows.
Ping is the only protocol configured. The timeout is set to 5 and the retries to 2.. Anyone have any ideas, it's got to be a problem with the new version as it was fine before hand, now it's becoming a headache..
Cheers.

Re: False SIM "System is unreachable" messages

Same here. And yes the system does not seem to use the settings I changed (timeout, retries).

Re: False SIM "System is unreachable" messages

I've been getting the same issue with SIM 4.2. I've upgraded from 4.1 and was NOT getting this issue.

I receive a LOT of false messages but only when SIM is performing an autodiscovery. I receive many false messages about many different events (not just reachable/unreachable) for the duration of the autodiscovery. The messages stop as soon as discovery is complete.

All of my discovery/alerting settings are the same as 4.1 - never seen this issue before.

HP: any "insight" into this problem?

David - Do you know which v4.2 MIB contains the 'server reachable' and 'server unreachable' traps? in v4.1 this located in the "Systems Insight Manager Events" when creating a new event task.
