Package: collectd-core
Severity: wishlist
collectd generates "notifications" internally, and its notify_email
plugin provides a notification handler that will send an email for
each one.
I prefer notifications to turn into syslog entries, so that even if
there are a hundred notifications all at once, I'll only get one email
from logcheck at the end of the hour.
This can be done by hand using NotificationExec, but I think this
functionality would be useful to be built-in as a C plugin.
FYI, here's what I'm doing now:
<Threshold>
<Type "df">
DataSource "used"
WarningMax 80
FailureMax 90
Percentage true
</Type>
</Threshold>
LoadPlugin exec
<Plugin exec>
NotificationExec "nobody:nogroup" "/etc/collectd/notify-syslog.sh"
</Plugin>
where the wrapper script exists mainly to discard the "headers" and
log only the "message" part:
#!/bin/sh
while read x y
do case "$x$y" in
'') exec logger -t collectd${severity+" $severity" -p
user."$severity"};;
Severity:WARNING) severity=warning;;
Severity:OKAY) severity=notice;;
Severity:FAILURE) severity=err;;
esac
done
The result is servicable, if suboptimal:
