Re: manage unknown status of node in NNM 9.10

You need to check the routing between the device and the NNMI server, step by step if need be. (ie traceroute x.x.x.x and then by FQDN  see how close you can get before it stops)

 

You need to check the device for any Access Control Lists (ACL) that might prevent it from reaching its destination.

 

You need to check any firewalls in between the NNMI server and the device for proper authorization (ports 161 , 162)

Have a nice day :)

Re: manage unknown status of node in NNM 9.10

i hear you, all these points make sense. but we have run into issues where a node or more commonly an interface was up/normal and then changed into unknown state which obviously suggests that theres an issue & there isnt any way currently for nnmi to trigger an alert on this....

[ Edited ]

The following is a workaround for "Unknown" status which doesn't send alerts.

 

Make sure all nodes are a part of the "Important Nodes" group.  Any member of the Important Nodes group will not go into Unknown status if unavailable/down. Instead it will go into Minor/Major/Warning/Critical status.

 

In the Additional Filters tab in the Important Nodes group, create a rule to include any node you wish that will no longer go into unknown status.

 

Once those nodes are a part of the Important Nodes group, you will always recieve the critical alerts attributed to the group.

 

I've never been able to figure out why HP designed NNM this way.

 

Best Regards,

 

David

If this solution ends up working (please test and verify in your environement), do the following.

 

1. Mark the corresponding answer in the forum as the solution, so others who may have the same issue, in the future, can reference.

2. Please give cudos to helpful answers :)

Re: manage unknown status of node in NNM 9.10

Hi,

This soultion is fine,but I can implement it as we have approx 1000 devices and adding all the devices is not a good option.Thanks again for help.
