101 ENHANCEMENTS
102 check_mailq now supports auto detection of qmail, postfix, exim and nullmailer with
103 fallback to sendmail
104 check_ide_smart now defaults to plugin output, original output appended with -v

107 check_swap now supports a configurable state when there is no swap
108 check_radius now supports the FreeRADIUS Client library

110 New check_mysql_query -g option to specify a client options group
111 Add performance data to check_mysql_query
112 New check_file_age -i/--ignore-missing option to return OK on nonexistent files
113 Make check_ping, check_users, and check_disk work on Windows
114 New check_ssh -P option to specify the expected SSH protocol version
115 check_dns now emits the warning and critical thresholds with the performance data
117 FIXES

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

127 Fix compilation with GnuTLS
129 WARNINGS
130 New default installation prefix: /usr/local instead of /usr/local/nagios
131 check_snmp now evaluates negative values properly, which means it might return CRITICAL
132 in cases where it used to return OK. If this is undesired, the warning/critical
133 threshold(s) must be fixed by specifying e.g. ~:100 instead of 100
134 check_procs now ignores its parent process to avoid unexpected results when invoked via
135 certain shells
136 utils.sh no longer defines ECH
137 check_ide_smart -q/--quiet and -n/--nagios (Nagios-compatible output) are now deprecated
138 but accepted for backward-compatibility
139 check_ide_smart -0/--auto-off, -1/--auto-on and -i/--immediate: options have
140 been disabled because they were broken
141 State retention: the NAGIOS_PLUGIN_STATE_DIRECTORY environment variable has been
142 renamed MP_STATE_PATH. The old variable will continue to work in v2.0.x
143 Add the UID of the invoking user to the state retention file path. This helps solving
144 permission issues when different users run the same plugin
145 check_swap used to allow returning OK on a system without swap when only percent thresholds
146 were used. This is no longer the case and one must now use -n/--no-swap=<state>
147 The Perl and Shell plugins now use the PATH specified via ./configure's --trusted-path
148 option, or "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin" by default
150 1.5 2nd October 2013

169 New check_pgsql -o option to specify additional connection parameters
170 New check_fping -S option to specify the source IP address
171 New check_fping -I option to specify the interface to bind to
172 Let check_fping support IPv6
173 New check_procs -k option to ignore kernel threads (on Linux)
174 Let check_procs use /proc/<PID>/exe (if available) instead of getpid(2), unless -T is specified
175 Let check_mysql support SSL
176 Let check_mysql add perfromance metrics for all checks
177 New check_mysql -f option to specify a client options file
178 New check_mysql -g option to specify a client options group
179 New check_snmp --offset option to allow for adding/substracting an offset value to sensor data
180 Let check_snmp support an arbitrary number of OIDs
181 Let check_ide_smart support NetBSD
183 FIXES

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

341 check_dig can now pass arguments to dig by using -A/--dig-arguments (#1874041/#1889453)
342 check_ntp and check_ntp_peer now show proper jitter/stratum thresholds longopts in --help

353 1.4.11 13th December 2007
354 Fixed check_http regression in 1.4.10 where following redirects to
355 relative URLs on virtual hosts failed if both "-H" and "-I" were used
356 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
357 You should read the --help output so see which one is suitable for you. check_ntp_peer
358 implement stratum thresholds support (feature request #1703823).
359 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
360 as long as the thresholds range include -1. If no offset threshold is specified
361 and the offset is unavailable, will return UNKNOWN as well.
362 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
363 is "-1" as the default range starts at 0. See Examples in --help output.

375 Fix check_http buffer overflow vulnerability when following HTTP redirects (CVE-2007-5198)
376 check_http now explicitly asks HTTP/1.1 servers to close the connection
377 after completion of the response
378 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
379 is now deprecated. See --help for further information.
380 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
381 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
382 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
383 Thus accessibility of remote filesystems can be checked without any threshold comparison.
384 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
385 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
386 New check_disk -A option to select all filesystems explicitly
387 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
388 Passing -E after -p or -r results in UNKNOWN state, now
389 This is needed due to the new ignore feature
390 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
391 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
392 to check DHCP servers on remote networks

396 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
397 Fix check_smtp's handling of multiple-packet server responses
398 WARNING: Fix for negate which may break existing commands:
399 - stop evaluating command line options through shell twice
400 - enforce a full path for the command to run
401 The "negate" utility can now remap custom states
402 Check_radius now supports radiusclient-ng
403 The (undocumented) positional parameter parsing which check_radius used
404 instead of getopt(3) if 8 arguments were given is no longer available
405 Check_by_ssh now supports multiline output
406 IPv6 support can now be disabled using ./configure --without-ipv6
407 Fix check_ntp now honor ntp flags
409 1.4.9 4th June 2007
410 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
411 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh
