curl output not found in tcpdump
I tried to use curl to test a monitoring script and found the desired pattern to match. However the monitor still marks the pool member as down. I then used tcpdump to check the actual packet but I did not find that pattern.
Am I missing something?
- nitassEmployeewhat the tcpdump command did you use? was the vlan name correct?
- Daniel_55334AltostratusI used "tcpdump -i external -X -s0 host xxx and port 80". vlan name is correct as I really see related output, but just not the desired pattern.
What I see is that there are a lot of output when using curl, but just very little during tcpdump capture when the monitor was turned on.
- nitassEmployeepool member is in external vlan, isn't it?
- Daniel_55334AltostratusYes I did check the capture in wireshark but still did not find the expected text pattern. What may be the cause of this?
- nitassEmployeehow did you create monitor script file? did you upload it from pc to f5?
- Daniel_55334Altostratusno I just input it in the WEBUI
- nitassEmployeeno I just input it in the WEBUIisn't it external monitor script?
