FILTERS
the filter determines which bugs to check, either by assignee, product or the
product's component. For backward compatibility, if just an email address is
provided, it will be used as the assignee.
--assignee <email> filter bugs by assignee
--product <name> filter bugs by product name
--component <name> filter bugs by product's component name
--unassigned <email> set the unassigned user (default: $config->{unassigned})
SEVERITIES
by default alerts and warnings will be generated for 'major', 'critical', and
'blocker' bugs. you can alter this list with the 'severity' switch.
setting severity to 'any' will result in alerting on unassigned bugs
regardless of severity.
--severity <major|critical|blocker>[,..]
--severity any
TIMING
time in hours to wait before paging or warning.
--major_alarm <hours> (default: $config->{major_alarm})
--major_warn <hours> (default: $config->{major_warn})
--critical_alarm <hours> (default: $config->{critical_alarm})
--critical_warn <hours> (default: $config->{critical_warn})
--blocker_alarm <hours> (default: $config->{blocker_alarm})
--blocker_warn <hours> (default: $config->{blocker_warn})
when severity checking is set to "any", use the any_* switches instead:
--any_alarm <hours> (default: $config->{any_alarm})
--any_warn <hours> (default: $config->{any_warn})
NAGIOS SELF-TERMINATION
In case of a hung process, this script self-terminates. You can adjust:
--max_runtime <seconds> (default: $config->{max_runtime})
EXAMPLES
nagios_blocker_checker.pl --assignee server-ops\@mozilla-org.bugs
nagios_blocker_checker.pl server-ops\@mozilla-org.bugs
nagios_blocker_checker.pl --product 'Release Engineering' \
--component 'Loan Requests' \
--severity any --any_warn 24 --any_alarm 24
