Hi
We're formatting a few status messages as HTML and we are using the perl HTML script from Andy France/Martin Ward/David Baldwin. Our mails kept getting truncated at around 4000 characters.
After looking around in the source code (do_alert.c) I found out that the variable passed to the SCRIPT alert type is limited to 4096 characters. I increased the value to 12288 and recompiled the xymond_alert binary. After replacing it in our production system the script now receives the complete status message.
Why can we configure the MAXMSG size for status messages but is the status truncated to 4KB? I'm wondering if there's any harm in upping the MAX_ALERTMSG_SCRIPTS value. Memory? Stabililty?
Since the data's being passed via environment variable, a safety limit is definitely a good idea, but modern systems should be able to exceed 4k easily enough, so I don't think you'd see any negative effects going up a bit higher.
I'd agree, it'd be preferable to set this via environment variable. Even better would be a SCRIPT-like directive that takes the status/page message body via STDIN instead.
