Packet drops on the interface statistics

We find packet drops on the interface statistics, it seems it happened during the deployment. But wanted to make sure currently there are no drops. Can we have an option to check when the last packet drop updated to interface statistics? tmsh show net interface all-properties tmsh show sys tmm-traffic

 

These commands do not show the information about the date when the last drop or change to the interface stats.

 

  • It is diffcult to find when last interface error was. It may be possible if you configured your F5 to send total logs (all level logs) to sysslog server.

     

    But you can verify from now onwards whether interface errors are increasing or not using below command. If errors are not increasing your inteface health is good.

     

    netstat -nsi

    Most stats don't

     

    However the numbers themselves are a counter. So what I'd normally do is to poll the counters and save them somewhere... An RRD, or something more sophisticated. Then graph the difference between successive readings and it becomes obvious when the drops occurred.

     

    Cacti has a fairly good set of stats for both specific BigIP counters (LTM/GTM/APM etc) and generic network level stats which will include your drops as well. But you could use nags or solar winds or whatever you prefer.
