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

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).
