It appears to have been an issue with the object (host) .cfg files of the cisco nexus switches. We resolved the issue by removing the cisco nexus host/object .cfg files ... restarting nagios without them ... then we re-added the same exact nexus .cfg files back to the same directory and restarted na...

We've built out another test environment that mimics our production environment and noticed that when we reduce the number of interfaces that we monitor on our switch, the alerts seem to stop. We've also adjusted the normal_check_interval from 5 to 10 Each of our switches has approx. 70 interfaces e...

In addition, we have nearly 75 interfaces that we are performing the interface bandwidth check on.

We have another pair of other Cisco Nexus switches that are experiencing the same issue, but just not as frequent ... these switches only have 58 interfaces that have the bandwidth monitor.

Thanks!

Is there any updated/newer plugin version that can effectively monitor Nexus interface bandwidth (64bit). I believe the OIDs used for 64bit interface bandwidth calculations are: 'ifRX64' => '.1.3.6.1.2.1.31.1.1.1.6.', # interface bytes in (64-bit) 'ifTX64' => '.1.3.6.1.2.1.31.1.1.1.10.' # interface ...

It seems like we receive two types of alerts:

1. Bandwidth;CRITICAL;SOFT;1;CRITICAL SNMP agent failure: No response from remote host

2. Bandwidth;CRITICAL;SOFT;2;CRITICAL Count not communitate with SNMP agent: No response from remote host

When we receive a Bandwidth alert on a specific interface: I am able to walk that specific alerting interface from our nagios server. I am walking for the specific OIDs that are used to calculate the bandwidth. I've also ran a tcpdump on a specific interface and it there are no dropped packets ... e...

So we just tried to change the default value: 'timeout' => 120, However, we started getting this error: Bandwidth;CRITICAL;HARD;3;CRITICAL SNMP connection failed on 172.22.255.33 with error: Invalid timeout value [120], range 1.0 - 60.0 seconds So we've now changed it to 60 seconds. But still receiv...

Thanks for your feedback: Would it be acceptable if I change the following 'timeout' value below under: # command-line controlled options (set-up with default values) %_options = ( 'timeout' => 120 , =========== OR ========= If -t 120 is the recommended process, where exactly does this value/code ge...

This is the code that our script is based on:

Really do appreciate your help ... as this is a mystery for us!
