60 ENHANCEMENTS
61 check_mailq now supports auto detection of qmail, postfix, exim and nullmailer with
62 fallback to sendmail
63 check_ide_smart now defaults to plugin output, original output appended with -v

65 https://www.monitoring-plugins.org/doc/extra-opts.html
66 check_swap now supports a configurable state when there is no swap
67 check_radius now supports the FreeRADIUS Client library
68 New check_mysql_query -f option to specify a client options file
69 New check_mysql_query -g option to specify a client options group
70 Add performance data to check_mysql_query
71 New check_file_age -i/--ignore-missing option to return OK on nonexistent files
72 Make check_ping, check_users, and check_disk work on Windows

76 FIXES
77 Don't let e.g. check_http's -C option reset SSL version if e.g. -S 1 -C 5 is specified
78 Don't have check_http's -N option expect an argument
79 check_ide_smart could disable offline auto tests but could not re-enable them.
80 For this reason all SMART command modes have been disabled.
81 check_dig: fix wrong IPv6 arguments order (Stéphane Bortzmeyer)
82 check_dig: make sure not to give up too early when a timeout is specified with -t
83 check_log: don't stumble over log lines that include a "%" character
84 check_nt: add UPTIME to perfdata
85 Handle SNMPv3 noAuthNoPriv properly with check_snmp
86 Fix compilation with GnuTLS
88 WARNINGS
89 New default installation prefix: /usr/local instead of /usr/local/nagios
90 check_snmp now evaluates negative values properly, which means it might return CRITICAL
91 in cases where it used to return OK. If this is undesired, the warning/critical
92 threshold(s) must be fixed by specifying e.g. ~:100 instead of 100
93 check_procs now ignores its parent process to avoid unexpected results when invoked via
94 certain shells
95 utils.sh no longer defines ECH
96 check_ide_smart -q/--quiet and -n/--nagios (Nagios-compatible output) are now deprecated
97 but accepted for backward-compatibility
98 check_ide_smart -0/--auto-off, -1/--auto-on and -i/--immediate: options have
99 been disabled because they were broken
100 State retention: the NAGIOS_PLUGIN_STATE_DIRECTORY environment variable has been
101 renamed MP_STATE_PATH. The old variable will continue to work in v2.0.x
102 Add the UID of the invoking user to the state retention file path. This helps solving
103 permission issues when different users run the same plugin
104 check_swap used to allow returning OK on a system without swap when only percent thresholds
105 were used. This is no longer the case and one must now use -n/--no-swap=<state>
106 The Perl and Shell plugins now use the PATH specified via ./configure's --trusted-path
107 option, or "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin" by default
109 1.5 2nd October 2013

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

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

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

318 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
319 as long as the thresholds range include -1. If no offset threshold is specified
320 and the offset is unavailable, will return UNKNOWN as well.

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

336 after completion of the response
337 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
338 is now deprecated. See --help for further information.
339 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
340 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
341 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
342 Thus accessibility of remote filesystems can be checked without any threshold comparison.
343 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
344 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
345 New check_disk -A option to select all filesystems explicitly

347 Passing -E after -p or -r results in UNKNOWN state, now
348 This is needed due to the new ignore feature
349 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
350 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
351 to check DHCP servers on remote networks

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

382 Respects --without-world-permissions for setuid plugins
383 check_disk extra options for regex matching of filesystems and grouping of filesystems
384 for collective thresholds
385 Better configure test for mysqlclient availability
386 Various check_ntp fixes
388 1.4.7 29th March 2007

390 Fixed MKINSTALLDIRS problem in po/
391 ./configure now detects if possible to compile check_mysql
392 Fixed broken HELO in check_smtp
393 check_icmp now allows to set a minimum number of hosts required for successs (-m)
394 check_icmp fix for *BSD when running for long time
395 check_ping times out 1 second quicker if host is unreachable
396 Root plugins installed with world executable
397 check_sybase from contrib now maintained in MonitoringExchange
