http test flapping 🔗 link

Hey,

I'm hoping someone has run into this and was able to track down how to
determine why http tests are flapping.  They used to run consistently for
days but now I'm lucky if the test stays green for more than a minute.
It's rarely the same test twice that fails (times out?) and sometimes it's
different hosts.  The history looks like a christmas-y candy cane.
However, if I run curl commands, they work fine.  I'm strongly suspicious
it's a network or system resource issue but I can't even see anything that
is actually logging why it's failing.  I've tried bumping the timeout up
but that doesn't seem to help.  Anyone have any ideas on what I can bump to
either get better logs or where else to look?  Only http is experiencing
this.

thanks

Look at the 'source' address of your red and green messages.

It is possible your server is being fed messages from two different sources. One source always succeeded, while the other always fails. The result would be flapping.

If it is getting mixed info, I can't get it to rep by running 'watch
dig +short myserver' on the Xymon server (since this is http test).  Which
log would that be in?

thanks
