I'm running the same http command multiple times but get different output. Do you know why this is happening?

HTTP OK: Status line output matched "HTTP/1.1 200,303" - 25882 bytes in 0.013 second response time |time=0.012552s;;;0.000000 size=25882B;;;0
[nagios@MA100DLVMON8 libexec]$ ./check_http -H ma100blvwsg5 -p 80 -u "/resources" -e "HTTP/1.1 200,303"
HTTP CRITICAL - No data received from host

i would guess intermittent issues possibly as usually check_http is pretty reliable. try running it with -v to see if that proves to be more information.

if you run a curl -v against it, do you see the same intermittent results?

with -v option i can see one of the member in bad state. Thanks.

Did you have any further (related) questions or are we okay to close this thread?
