88 ENHANCEMENTS
89 check_mailq now supports auto detection of qmail, postfix, exim and nullmailer with
90 fallback to sendmail

93 https://www.monitoring-plugins.org/doc/extra-opts.html
94 check_swap now supports a configurable state when there is no swap
95 check_radius now supports the FreeRADIUS Client library

97 New check_mysql_query -g option to specify a client options group
98 Add performance data to check_mysql_query
99 New check_file_age -i/--ignore-missing option to return OK on nonexistent files
100 Make check_ping, check_users, and check_disk work on Windows
101 New check_ssh -P option to specify the expected SSH protocol version
102 check_dns now emits the warning and critical thresholds with the performance data
104 FIXES

106 Don't have check_http's -N option expect an argument
107 check_ide_smart could disable offline auto tests but could not re-enable them.
108 For this reason all SMART command modes have been disabled.
109 check_dig: fix wrong IPv6 arguments order
110 check_dig: make sure not to give up too early when a timeout is specified with -t
111 check_log: don't stumble over log lines that include a "%" character

114 Fix compilation with GnuTLS
116 WARNINGS
117 New default installation prefix: /usr/local instead of /usr/local/nagios
118 check_snmp now evaluates negative values properly, which means it might return CRITICAL
119 in cases where it used to return OK. If this is undesired, the warning/critical
120 threshold(s) must be fixed by specifying e.g. ~:100 instead of 100
121 check_procs now ignores its parent process to avoid unexpected results when invoked via
122 certain shells
123 utils.sh no longer defines ECH
124 check_ide_smart -q/--quiet and -n/--nagios (Nagios-compatible output) are now deprecated
125 but accepted for backward-compatibility
126 check_ide_smart -0/--auto-off, -1/--auto-on and -i/--immediate: options have
127 been disabled because they were broken
128 State retention: the NAGIOS_PLUGIN_STATE_DIRECTORY environment variable has been
129 renamed MP_STATE_PATH. The old variable will continue to work in v2.0.x
130 Add the UID of the invoking user to the state retention file path. This helps solving
131 permission issues when different users run the same plugin
132 check_swap used to allow returning OK on a system without swap when only percent thresholds
133 were used. This is no longer the case and one must now use -n/--no-swap=<state>
134 The Perl and Shell plugins now use the PATH specified via ./configure's --trusted-path
135 option, or "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin" by default
137 1.5 2nd October 2013

156 New check_pgsql -o option to specify additional connection parameters
157 New check_fping -S option to specify the source IP address
158 New check_fping -I option to specify the interface to bind to
159 Let check_fping support IPv6
160 New check_procs -k option to ignore kernel threads (on Linux)
161 Let check_procs use /proc/<PID>/exe (if available) instead of getpid(2), unless -T is specified
162 Let check_mysql support SSL
163 Let check_mysql add perfromance metrics for all checks
164 New check_mysql -f option to specify a client options file
165 New check_mysql -g option to specify a client options group
166 New check_snmp --offset option to allow for adding/substracting an offset value to sensor data
167 Let check_snmp support an arbitrary number of OIDs
168 Let check_ide_smart support NetBSD
170 FIXES
171 Change the MAIL FROM command generated by check_smtp to be RFC compliant

176 Fix check_http handling extra header (-k) containing semicolons
177 Fix check_apt handling unknown exit codes from apt-get
178 Fix deprecated imports of check_nmap.py
180 WARNINGS
181 check_http behaviour of -k/--header changed since it does not seperate multiple headers by semicolons anymore. Use multiple -k switches instead.
182 check_http's --proxy_authorization option is now called --proxy-authorization (it was always documented this way)
183 The contrib directory has been removed from this distribution

328 check_dig can now pass arguments to dig by using -A/--dig-arguments (#1874041/#1889453)
329 check_ntp and check_ntp_peer now show proper jitter/stratum thresholds longopts in --help
330 check_dns now allow to repeat -a to match multiple possibly returned address (common with load balancers)
331 check_mysql and check_radius now try clearing password in processlist just like check_mysql_query
332 check_mysql and check_mysql_query now support sockets explicitely (-s, --socket)

340 1.4.11 13th December 2007
341 Fixed check_http regression in 1.4.10 where following redirects to
342 relative URLs on virtual hosts failed if both "-H" and "-I" were used
343 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
344 You should read the --help output so see which one is suitable for you. check_ntp_peer
345 implement stratum thresholds support (feature request #1703823).
346 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
347 as long as the thresholds range include -1. If no offset threshold is specified
348 and the offset is unavailable, will return UNKNOWN as well.
349 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
350 is "-1" as the default range starts at 0. See Examples in --help output.
351 Fixed broken usage2 in check_snmp and check_cluster
352 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")

363 check_http now explicitly asks HTTP/1.1 servers to close the connection
364 after completion of the response
365 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
366 is now deprecated. See --help for further information.
367 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
368 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
369 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
370 Thus accessibility of remote filesystems can be checked without any threshold comparison.
371 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
372 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
373 New check_disk -A option to select all filesystems explicitly
374 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
375 Passing -E after -p or -r results in UNKNOWN state, now
376 This is needed due to the new ignore feature
377 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
378 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
379 to check DHCP servers on remote networks

383 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
384 Fix check_smtp's handling of multiple-packet server responses
385 WARNING: Fix for negate which may break existing commands:
386 - stop evaluating command line options through shell twice
387 - enforce a full path for the command to run
388 The "negate" utility can now remap custom states
389 Check_radius now supports radiusclient-ng
390 The (undocumented) positional parameter parsing which check_radius used
391 instead of getopt(3) if 8 arguments were given is no longer available
392 Check_by_ssh now supports multiline output
393 IPv6 support can now be disabled using ./configure --without-ipv6
394 Fix check_ntp now honor ntp flags
396 1.4.9 4th June 2007
397 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
398 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh

405 check_snmp don't warn anymore if something is printed on stderr
406 Fix check_tcp segfault when multiple expect strings are given
407 New option for check_tcp: -A/--all to test if all given expect strings match
409 1.4.8 11th April 2007
410 Respects --without-world-permissions for setuid plugins
411 check_disk extra options for regex matching of filesystems and grouping of filesystems
412 for collective thresholds
413 Better configure test for mysqlclient availability
414 Various check_ntp fixes
416 1.4.7 29th March 2007
