There are a few services in which chat scripts may not be desirable. For
example, SSL or SSH.
Have people really been having a problem with slowdowns and such? My
linuxdirector checks a plethora of services every check and seems to respond
close to immediately when a real server goes down. I'm using mon on top of
that.
Another idea regarding alerts. I've never used ldirectord -- is it C? Perl?
If it's perl, it'd be easy to have it read in a configuration file of alerts
which really would be more like a list of files to include. It could then
include those files (error checking would be needed to be sure that if any
of those files had a little bug in them they wouldn't take down the whole
ldirectord) and call functions within those files of the same name of those
files. Does that make sense? That would keep the ldirectord from spawning
new processes to just use perl, yesno? It would have already compiled those
and would just be calling local functions.
For example...
ldmonmod.conf =====
pop_mon.pl
=====
ldirectord parses that conf file, includes pop_mon.pl, and then runs the
pop_mon alert.
Extra information could be stored in the conf file regarding how to handle
running that particular monitor...
Would increase the memory footprint of ldirectord, but wouldn't that help to
speed things up and integrate the monitors more directly into the daemon?
