59 ENHANCEMENTS
60 check_mailq now supports auto detection of qmail, postfix, exim and nullmailer with
61 fallback to sendmail
62 check_ide_smart now defaults to plugin output, original output appended with -v
63 Extra-Opts are now enabled by default, see:
64 https://www.monitoring-plugins.org/doc/extra-opts.html
65 check_swap now supports a configurable state when there is no swap
66 check_radius now supports the FreeRADIUS Client library
67 New check_mysql_query -f option to specify a client options file
68 New check_mysql_query -g option to specify a client options group
69 Add performance data to check_mysql_query
70 New check_file_age -i/--ignore-missing option to return OK on nonexistent files
71 Make check_ping, check_users, and check_disk work on Windows
72 New check_ssh -P option to specify the expected SSH protocol version
73 check_dns now emits the warning and critical thresholds with the performance data
75 FIXES
76 Don't let e.g. check_http's -C option reset SSL version if e.g. -S 1 -C 5 is specified
77 Don't have check_http's -N option expect an argument
78 check_ide_smart could disable offline auto tests but could not re-enable them.
79 For this reason all SMART command modes have been disabled.
80 check_dig: fix wrong IPv6 arguments order (Stéphane Bortzmeyer)
81 check_dig: make sure not to give up too early when a timeout is specified with -t
82 check_log: don't stumble over log lines that include a "%" character
83 check_nt: add UPTIME to perfdata
84 Handle SNMPv3 noAuthNoPriv properly with check_snmp
85 Fix compilation with GnuTLS
87 WARNINGS
88 New default installation prefix: /usr/local instead of /usr/local/nagios
89 check_snmp now evaluates negative values properly, which means it might return CRITICAL
90 in cases where it used to return OK. If this is undesired, the warning/critical
91 threshold(s) must be fixed by specifying e.g. ~:100 instead of 100
92 check_procs now ignores its parent process to avoid unexpected results when invoked via
93 certain shells
94 utils.sh no longer defines ECH
95 check_ide_smart -q/--quiet and -n/--nagios (Nagios-compatible output) are now deprecated
96 but accepted for backward-compatibility
97 check_ide_smart -0/--auto-off, -1/--auto-on and -i/--immediate: options have
98 been disabled because they were broken
99 State retention: the NAGIOS_PLUGIN_STATE_DIRECTORY environment variable has been
100 renamed MP_STATE_PATH. The old variable will continue to work in v2.0.x
101 Add the UID of the invoking user to the state retention file path. This helps solving
102 permission issues when different users run the same plugin
103 check_swap used to allow returning OK on a system without swap when only percent thresholds
104 were used. This is no longer the case and one must now use -n/--no-swap=<state>
105 The Perl and Shell plugins now use the PATH specified via ./configure's --trusted-path
106 option, or "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin" by default
108 1.5 2nd October 2013

128 New check_fping -S option to specify the source IP address
129 New check_fping -I option to specify the interface to bind to
130 Let check_fping support IPv6
131 New check_procs -k option to ignore kernel threads (on Linux)
132 Let check_procs use /proc/<PID>/exe (if available) instead of getpid(2), unless -T is specified
133 Let check_mysql support SSL
134 Let check_mysql add perfromance metrics for all checks
135 New check_mysql -f option to specify a client options file
136 New check_mysql -g option to specify a client options group
137 New check_snmp --offset option to allow for adding/substracting an offset value to sensor data
138 Let check_snmp support an arbitrary number of OIDs

149 Fix deprecated imports of check_nmap.py (Fabio Rueda)
151 WARNINGS
152 check_http behaviour of -k/--header changed since it does not seperate multiple headers by semicolons anymore. Use multiple -k switches instead.
153 check_http's --proxy_authorization option is now called --proxy-authorization (it was always documented this way)
154 The contrib directory has been removed from this distribution

223 single quote in the label
224 check_http 1.4.14 introduced SSL SNI support - you now have to enable it explicitly with "--sni"

314 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
315 You should read the --help output so see which one is suitable for you. check_ntp_peer

317 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
318 as long as the thresholds range include -1. If no offset threshold is specified
319 and the offset is unavailable, will return UNKNOWN as well.
320 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
321 is "-1" as the default range starts at 0. See Examples in --help output.

335 after completion of the response
336 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
337 is now deprecated. See --help for further information.
338 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
339 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
340 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
341 Thus accessibility of remote filesystems can be checked without any threshold comparison.
342 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
343 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
344 New check_disk -A option to select all filesystems explicitly
345 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
346 Passing -E after -p or -r results in UNKNOWN state, now
347 This is needed due to the new ignore feature
348 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
349 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
350 to check DHCP servers on remote networks

355 Fix check_smtp's handling of multiple-packet server responses
356 WARNING: Fix for negate which may break existing commands:
357 - stop evaluating command line options through shell twice
358 - enforce a full path for the command to run
359 The "negate" utility can now remap custom states
360 Check_radius now supports radiusclient-ng
361 The (undocumented) positional parameter parsing which check_radius used
362 instead of getopt(3) if 8 arguments were given is no longer available
363 Check_by_ssh now supports multiline output
364 IPv6 support can now be disabled using ./configure --without-ipv6
365 Fix check_ntp now honor ntp flags
367 1.4.9 4th June 2007
368 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
369 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh

380 1.4.8 11th April 2007
381 Respects --without-world-permissions for setuid plugins
382 check_disk extra options for regex matching of filesystems and grouping of filesystems
383 for collective thresholds
384 Better configure test for mysqlclient availability
385 Various check_ntp fixes
387 1.4.7 29th March 2007
388 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
389 Fixed MKINSTALLDIRS problem in po/
390 ./configure now detects if possible to compile check_mysql
391 Fixed broken HELO in check_smtp
392 check_icmp now allows to set a minimum number of hosts required for successs (-m)
393 check_icmp fix for *BSD when running for long time
394 check_ping times out 1 second quicker if host is unreachable
395 Root plugins installed with world executable
396 check_sybase from contrib now maintained in MonitoringExchange
