Running long-living tcpdumps on BigIP
Hi guys,
I'm not quite sure if this is the right forum to post the question, but I couldn't find a more suitable one...
I often need the possibility to monitor specific client connections to virtual servers for a long time (in order to capture sporadic errors). tcpdump on the BigIp comes in very handy, although its major drawback is that you need to keep open the SSH connection to the Big IP all the time, which is not possible for me in most cases (especially when waiting for an reoccurring error many hours or even several days).
On a "normal" linux system, I would use 'screen' in order to make any program run in the background even after disconnecting from the host. Unfortunately, screen is not available on BigIP systems. Furthermore, I'm having concerns regarding performance when running tcpdump in the background for a long time.
Anybody here with a good idea how to cope with such issues? Any shared experience is appreciated. Thanks a lot in advance!
Greetings
Martin
