|
|
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, see:
|
|
https://www.monitoring-plugins.org/doc/extra-opts.html
|
|
check_swap now supports a configurable state when there is no swap
|
|

|
|
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
|
|
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 variable 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
|
|
|
|
1.5 2nd October 2013

is "-1" as the default range starts at 0. See Examples in --help output.

|
|
after completion of the response
|
|
Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
|
|
is now deprecated. See --help for further information.
|
|
Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)

|
|
WARNING: Fix for negate which may break existing commands:
|
|
- stop evaluating command line options through shell twice
|
|
- enforce a full path for the command to run
|
|
The "negate" utility can now remap custom states
|
