1 This file documents the major additions and syntax changes between releases.
3 2.0 11th July 2014
4 ENHANCEMENTS
5 check_mailq now supports auto detection of qmail, postfix, exim and nullmailer with
6 fallback to sendmail
7 check_ide_smart now defaults to plugin output, original output appended with -v
8 Extra-Opts are now enabled by default, see:
9 https://www.monitoring-plugins.org/doc/extra-opts.html
10 check_swap now supports a configurable state when there is no swap
11 check_radius now supports the FreeRADIUS Client library
12 New check_mysql_query -f option to specify a client options file
13 New check_mysql_query -g option to specify a client options group
14 Add performance data to check_mysql_query
15 New check_file_age -i/--ignore-missing option to return OK on nonexistent files
16 Make check_ping, check_users, and check_disk work on Windows
17 New check_ssh -P option to specify the expected SSH protocol version
18 check_dns now emits the warning and critical thresholds with the performance data
20 FIXES
21 Don't let e.g. check_http's -C option reset SSL version if e.g. -S 1 -C 5 is specified
22 Don't have check_http's -N option expect an argument
23 check_ide_smart could disable offline auto tests but could not re-enable them.
24 For this reason all SMART command modes have been disabled.
25 check_dig: fix wrong IPv6 arguments order (Stéphane Bortzmeyer)
26 check_dig: make sure not to give up too early when a timeout is specified with -t
27 check_log: don't stumble over log lines that include a "%" character
28 check_nt: add UPTIME to perfdata
29 Handle SNMPv3 noAuthNoPriv properly with check_snmp
30 Fix compilation with GnuTLS
32 WARNINGS
33 New default installation prefix: /usr/local instead of /usr/local/nagios
34 check_snmp now evaluates negative values properly, which means it might return CRITICAL
35 in cases where it used to return OK. If this is undesired, the warning/critical
36 threshold(s) must be fixed by specifying e.g. ~:100 instead of 100
37 check_procs now ignores its parent process to avoid unexpected results when invoked via
38 certain shells
39 utils.sh no longer defines ECH
40 check_ide_smart -q/--quiet and -n/--nagios (Nagios-compatible output) are now deprecated
41 but accepted for backward-compatibility
42 check_ide_smart -0/--auto-off, -1/--auto-on and -i/--immediate: options have
43 been disabled because they were broken
44 State retention: the NAGIOS_PLUGIN_STATE_DIRECTORY environment variable has been
45 renamed MP_STATE_PATH. The old variable will continue to work in v2.0.x
46 Add the UID of the invoking user to the state retention file path. This helps solving
47 permission issues when different users run the same plugin
48 check_swap used to allow returning OK on a system without swap when only percent thresholds
49 were used. This is no longer the case and one must now use -n/--no-swap=<state>
50 The Perl and Shell plugins now use the PATH specified via ./configure's --trusted-path
51 option, or "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin" by default
53 1.5 2nd October 2013

73 New check_fping -S option to specify the source IP address
74 New check_fping -I option to specify the interface to bind to
75 Let check_fping support IPv6
76 New check_procs -k option to ignore kernel threads (on Linux)
77 Let check_procs use /proc/<PID>/exe (if available) instead of getpid(2), unless -T is specified
78 Let check_mysql support SSL
79 Let check_mysql add perfromance metrics for all checks
80 New check_mysql -f option to specify a client options file
81 New check_mysql -g option to specify a client options group
82 New check_snmp --offset option to allow for adding/substracting an offset value to sensor data
83 Let check_snmp support an arbitrary number of OIDs
84 Let check_ide_smart support NetBSD
86 FIXES

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

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

261 implement stratum thresholds support (feature request #1703823).
262 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
263 as long as the thresholds range include -1. If no offset threshold is specified
264 and the offset is unavailable, will return UNKNOWN as well.

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

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

299 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
300 Fix check_smtp's handling of multiple-packet server responses
301 WARNING: Fix for negate which may break existing commands:
302 - stop evaluating command line options through shell twice
303 - enforce a full path for the command to run
304 The "negate" utility can now remap custom states
305 Check_radius now supports radiusclient-ng
306 The (undocumented) positional parameter parsing which check_radius used
307 instead of getopt(3) if 8 arguments were given is no longer available
308 Check_by_ssh now supports multiline output
309 IPv6 support can now be disabled using ./configure --without-ipv6
310 Fix check_ntp now honor ntp flags
312 1.4.9 4th June 2007

327 check_disk extra options for regex matching of filesystems and grouping of filesystems
328 for collective thresholds
329 Better configure test for mysqlclient availability

332 1.4.7 29th March 2007

367 check_udp2 removed. check_udp is now linked to check_tcp.c
368 check_mailq now errors if the sub-program run returns non-zero return code. This would appear

370 Compile problems with check_snmp fixed
