check_imap_quota(7) connects to an IMAP account and checks the quota

SYNOPSIS


check_imap_quota -vV
check_imap_quota -?
check_imap_quota --help

OPTIONS

--warning <seconds>
Warn if it takes longer than <seconds> to connect to the IMAP server. Default is 15 seconds. Also known as: -w <seconds>
--critical <seconds>
Return a critical status if it takes longer than <seconds> to connect to the IMAP server. Default is 30 seconds. See also: --capture-critical <messages> Also known as: -c <seconds>
--timeout <seconds>
Abort with critical status if it takes longer than <seconds> to connect to the IMAP server. Default is 60 seconds. The difference between timeout and critical is that, with the default settings, if it takes 45 seconds to connect to the server then the connection will succeed but the plugin will return CRITICAL because it took longer than 30 seconds. Also known as: -t <seconds>
--hostname <server>
Address or name of the IMAP server. Examples: mail.server.com, localhost, 192.168.1.100 Also known as: -H <server>
--port <number>
Service port on the IMAP server. Default is 143. If you use SSL, default is 993. Also known as: -p <number>
--username <username>
--password <password>
Username and password to use when connecting to IMAP server. Also known as: -U <username> -P <password>
--mailbox <mailbox>
Use this option to specify the mailbox to search for messages. Default is INBOX. Also known as: -m <mailbox>
--ssl
--nossl
Enable SSL protocol. Requires IO::Socket::SSL.

Using this option automatically changes the default port from 143 to 993. You can still override this from the command line using the --port option.

Use the nossl option to turn off the ssl option.

--hires
Use the Time::HiRes module to measure time, if available.
--verbose
Display additional information. Useful for troubleshooting. Use together with --version to see the default warning and critical timeout values.

If the selected mailbox was not found, you can use verbosity level 3 (-vvv) to display a list of all available mailboxes on the server.

Also known as: -v

--version
Display plugin version and exit. Also known as: -V
--help
Display this documentation and exit. Does not work in the ePN version. Also known as: -h
--usage
Display a short usage instruction and exit.

EXAMPLES

Report how many emails are in the mailbox

 $ check_imap_receive -H mail.server.net --username mailuser --password mailpass
 -s ALL --nodelete
 IMAP RECEIVE OK - 1 seconds, 7 found

Report the email with the highest value

Suppose your mailbox has some emails from an automated script and that a message from this script typically looks like this (abbreviated): 

 To: [email protected]
 From: [email protected]
 Subject: Results of Autoscript
 Date: Wed, 09 Nov 2005 08:30:40 -0800
 Message-ID: <[email protected]>
 Homeruns 5

And further suppose that you are interested in reporting the message that has the highest number of home runs, and also to leave this message in the mailbox for future checks, but remove the other matching messages with lesser values: 

 $ check_imap_receive -H mail.server.net --username mailuser --password mailpass
 -s SUBJECT -s "Results of Autoscript" --capture-max "Homeruns (\d+)"  --nodelete-captured
 IMAP RECEIVE OK - 1 seconds, 3 found, 1 captured, 5 max, 2 deleted

Troubleshoot your search parameters

Add the --nodelete and --imap-retries=1 parameters to your command line.

EXIT CODES

Complies with the Nagios plug-in specification:
 0              OK                      The plugin was able to check the service and it appeared to be functioning properly

 1              Warning         The plugin was able to check the service, but it appeared to be above some ``warning'' threshold or did not appear to be working properly

 2              Critical        The plugin detected that either the service was not running or it was above some ``critical'' threshold

 3              Unknown         Invalid command line arguments were supplied to the plugin or the plugin was unable to check the status of the given hosts/service

NAGIOS PLUGIN NOTES

Nagios plugin reference: http://nagiosplug.sourceforge.net/developer-guidelines.html

This plugin does NOT use Nagios DEFAULT_SOCKET_TIMEOUT (provided by utils.pm as $TIMEOUT) because the path to utils.pm must be specified completely in this program and forces users to edit the source code if their install location is different (if they realize this is the problem). You can view the default timeout for this module by using the --verbose and --version options together. The short form is -vV.

Other than that, it attempts to follow published guidelines for Nagios plugins.
