Miscellaneous nagios checks

Run custom checks against the values in /proc/meminfo

USAGE:

 check_meminfo -w Buffers/MemTotal<0.7 -c Buffers/MemTotal<0.9

This will warn if your buffer memory usage > 0.7 of total memory & go critical if it's > 0.9

Monitor /proc/pressure on 4.2+ kernel linux systems

Usage: check_pressure.py [options]

Options:
-h, --help   show this help message and exit
-w WARNING   warning thresholds [default:
			"somecpu10>0.2,fullio10>0.2,fullmemory10>0.2"]
-c CRITICAL  critical thresholds [default:
			"somecpu10>0.5,fullio10>0.5,fullmemory10>0.5"]

Checks on a Red Hat / Centos / Ubuntu / Debian system whether services in init are running.

USAGE: check_init_service --services service1,service2


PARAMETERS:

	--services
		comma separated list of services to check, at least one required

	--matchregex
		optional regular expression to match against service svcname status
		output. Defaults to (?:is running|start/running)

	--svccmd
		optional. specify the "service" command for your OS (eg on Centos 7
		this would be /bin/systemctl, on Centos 6 /sbin/service, otherwise
		it will try & guess)

INSTALLATION

Unless you are using systemctl (ie Systemd) you must have a sudo entry for the user running this check (eg nagios). Also ensure that you disable requiring a tty for this user in sudoers

Defaults:nagios !requiretty
nagios ALL = NOPASSWD: /sbin/service * status

NOTE: python 2 only - see check_startup_service for enhanced python 3 version

Same as check_init_service but for python 3 and can also check if services are NOT running (eg for DR) by prefixing them with ^

 check_startup_service --services=postfix,^httpd

Checks whether the signature on a given JAR file has expired or is close to expiry.

Checks whether a domain name is close to expiry

Deprecated as format on webserver changed - see check_darwin

Graduated to its own repo! https://github.com/jamespo/check_multi_url

Checks if National Rail trains are running on schedule.

Usage: check_darwin -f [fromstationcode] -t [tostationcode]

eg for Southend Central to Limehouse

check_darwin -f SOC -t LHS

An alternative transport for remote nagios checks than NRPE - HTTP to get through firewalls etc.

Install check_nrpe_http_cgi.py as a cgi script on your client server and use check_nrpe_http on your Nagios / Icinga server to call the check.

Check the last n lines of a file (typically a logfile) for a line that matches a regex. If it matches, exit with CRITICAL. Use this for detecting fatal errors.

Usage: check_last_lines -f FILENAME -n NUMLINES -m MATCHREGEX

Check integrity of your mysql databases.
