Couldn't you use the control section to set a variable to the number of whatevers (files), and then set the class based on that? It'd also allow you to use the variable in the alerts to say how many there are.
Yah, but control: gets evaluated before classes (true)? How does one do this without running classes: twice? I'm still a newbie, care to share an example of how to do this?
/usr/bin/test `find /var/spool/mqueue -type f -name 'q*' | wc -l` -ge 12 > ----BEGIN SNIP > classes: > # See if we're overlimt > MailqueOverLimit = ( ReturnsZero(/bin/sh -c "expr `ls > /var/spool/mqueue/ | grep q.*| wc -l` \> 12 > /dev/null") )
control: MailQueueCount = ( ExecResult(find /var/spool/mqueue -type f -name 'q*' | wc -l )
classes:
MailqueOverLimit = ( ReturnsZero(/usr/bin/test $(MailQueueCount) -ge
12) )Warning; completely untested, but it hopefully indicates the way I was thinking. Mark, does this mean that boolean operations would be a good idea in cfengine?
Most of the time cfengine is easy, but sometimes I just think like it's
p{erl,php,dksh} :)
pphp? :). I know the feeling. I'm not always sure I'm thinking cfenginely myself.
Hmm. If I were doing it, I'd make a shell script. Of course, that would mean that alerts wouldn't work. I might also try a cfengine method.
Hmm.. I'm trying to reduce the scripties. We have one that does this now, in fact we have like 6 :)
:). Now you know why I have a management system for them (see cfengine-masterconf, on arpmats.sourceforge.net).
