Version 2.0 Released

Holger Weiß, July 11, 2014

The Monitoring Plugins Development Team is proud to announce the first release under the new project name: Version 2.0 of the Monitoring Plugins! This release comes with various enhancements and fixes provided by more than twenty contributors. Many thanks to all of you!

Let me also take the chance to welcome our newest team member, Sam Kottler. He already did lots of patch review for this release, and his expertise will no doubt help us a lot in the future, so we're really happy to have him on board!

One of the significant changes in the new release is that the Extra-Opts feature is now enabled by default. This lets you use a configuration file to specify plugin options. See the documentation for details.

For the list of other major changes in this release, see below. Note that a few of them might break certain configurations (hence the major version bump). Those are mentioned at the bottom of that list, so please be sure to check whether they might affect you.

You can get the tarball from our download page.

Enhancements

check_mailq now supports auto detection of qmail, postfix, exim and nullmailer with fallback to sendmail
check_ide_smart now defaults to plugin output, original output appended with -v
Extra-Opts are now enabled by default
check_swap now supports a configurable state when there is no swap
check_radius now supports the FreeRADIUS Client library
New check_mysql_query -f option to specify a client options file
New check_mysql_query -g option to specify a client options group
Add performance data to check_mysql_query
New check_file_age -i/--ignore-missing option to return OK on nonexistent files
Make check_ping, check_users, and check_disk work on Windows
New check_ssh -P option to specify the expected SSH protocol version
check_dns now emits the warning and critical thresholds with the performance data

Fixes

Don't let e.g. check_http's -C option reset SSL version if e.g. -S 1 -C 5 is specified
Don't have check_http's -N option expect an argument
check_ide_smart could disable offline auto-tests but could not re-enable them. For this reason all SMART command modes have been disabled
check_dig: fix wrong IPv6 arguments order (Stéphane Bortzmeyer)
check_dig: make sure not to give up too early when a timeout is specified with -t
check_log: don't stumble over log lines that include a % character
check_nt: add UPTIME to perfdata
Handle SNMPv3 noAuthNoPriv properly with check_snmp
Fix compilation with GnuTLS

Warnings

New default installation prefix: /usr/local instead of /usr/local/nagios
check_snmp now evaluates negative values properly, which means it might return CRITICAL in cases where it used to return OK. If this is undesired, the warning/critical threshold(s) must be fixed by specifying e.g. ~:100 instead of 100
check_procs now ignores its parent process to avoid unexpected results when invoked via certain shells
utils.sh no longer defines ECH
check_ide_smart -q/--quiet and -n/--nagios (Nagios-compatible output) are now deprecated but accepted for backward-compatibility
check_ide_smart -0/--auto-off, -1/--auto-on and -i/--immediate: options have been disabled because they were broken
State retention: the NAGIOS_PLUGIN_STATE_DIRECTORY environment variablew has been renamed MP_STATE_PATH. The old variable will continue to work in v2.0.x
Add the UID of the invoking user to the state retention file path. This helps solving permission issues when different users run the same plugin
check_swap used to allow returning OK on a system without swap when only percent thresholds were used. This is no longer the case and one must now use -n/--no-swap=<state>
The Perl and Shell plugins now use the PATH specified via ./configure's --trusted-path option, or /usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin by default
