xymon communications program (server/bin/xymon) reading from stdin - first line only?
Recently I tried to modify one of my xymon extension scripts, which passes the message data to the xymon command on the command line, to pass it via STDIN instead.
It worked (sort of), but I was not able to get xymon to process more than the first line of the message (the one with color, status, timestamp). The rest of the message seemed to be ignored.
This is xymon version 4.3.27. Is that a known problem?
Thanks,
glauber
I suspect you need to double-quote the final string. Without that, I suspect the xymon command is only reading everything up to the first line feed.
Can you provide an explicit example? ie "This worked...this didn't"

It's backward of that: the string in the command line worked (I didn't have to double-quote it because I wasn't running xymon from the shell, but from a Unix "system" call, via perl). When I tried the same string being fed via STDIN (passing - in the command line), it got processed up to the first newline. I also tried the --merge parameter (sending the first line in the commandline and the rest via stdin), but that errored out.
It's not a big problem - I just reverted to using the command line. Only rarely there is so much data that it exceeds the command line limits. Actually this was the first time i saw this happen, in years.
