Stale collections (8) has status Major

Hello All

NNM 10.2x on Linux

Past few days we see below error in System health information.

Stale collections (8) has status Major because there were between 5 and 10 stale collections in the last 5 minutes.

As per my understanding it is because NNM is unable to query few devices and waits for the response.

Is there any way to identify which devices where response is slow.

Longest Analysis Node        = nauh-dom
Longest Analysis time        = 11.9d

Node Rediscovery Requests
        Node Rediscovery Request Count Total = 1,244
        Node Rediscovery Request Error Count Total = 0
        Node Rediscovery Requests Most Recently:

Is this what you are referring.

Re: Stale collections (8) has status Major

Andy

Are you referring to,

Target		Late Responses
10.0.0.1		4228
10.0.0.2		1456


or

Target		Retransmissions
192.168.16.3		32672

 
Because in my environment I am seeing both of them, additionally I am seeing below as well,

Target        Parse Failures
192.168.22.122        274
10.0.1.155                250
