Create Nagios availability reports at the command line
There are several Perl modules that can query Nagios availability information but I didn't like any of them. They also required integration work into another script. I decided to create this one as a simple solution that could print statistics quickly, for when managers want uptime reports.
cgi
Define path to the Nagios availability CGI (avail.cgi) as a local file path. Defaults to /usr/lib64/nagios/cgi-bin/avail.cgi
u|user
Define user that Nagios runs as. Defaults to nagios
h|host
Define host to generate availability report for. Required parameter.
s|service
Define service to generate availability report for. Required parameter.
t|timeperiod
Define the time period to report on. Defaults to lastmonth. Choose from
today, last24hours, yesterday, thisweek, last7days, lastweek,
thismonth, last31days, lastmonth, thisyear, lastyear
o|output
Define the output format. Defaults to dump. Choose from:
-
dump- dumps the whole hash of availability information. Useful for debugging. -
uptime- prints the percentage of uptime -
downtime- prints the duration of downtime -
v|verbose
Define verbosity of output. Defaults to false. Adds full-sentence output to output formats uptime and downtime rather than just printing the number.
d|dontprinthost
Define whether to print the hostname in verbose output. Defaults to true.
r|recipients
The email address to send the report to. This option may be specified more than once to send multiple copies of the email. Leave blank to print the output to stdout (which causes cron to send an email instead).
Nagios BPI is a tool that can monitor a set of other Nagios services and aggregate the results to give an aggregate state. For example, if either DNS1 or DNS2 is up, then you can say that the DNS service itself is up. This script can be used to good effect with BPI to report aggregate uptime of your business services.
