39 2.0 11th July 2014
40 ENHANCEMENTS
41 check_mailq now supports auto detection of qmail, postfix, exim and nullmailer with
42 fallback to sendmail
43 check_ide_smart now defaults to plugin output, original output appended with -v
44 Extra-Opts are now enabled by default, see:
45 https://www.monitoring-plugins.org/doc/extra-opts.html
46 check_swap now supports a configurable state when there is no swap
47 check_radius now supports the FreeRADIUS Client library
48 New check_mysql_query -f option to specify a client options file
49 New check_mysql_query -g option to specify a client options group
50 Add performance data to check_mysql_query
51 New check_file_age -i/--ignore-missing option to return OK on nonexistent files
52 Make check_ping, check_users, and check_disk work on Windows
53 New check_ssh -P option to specify the expected SSH protocol version
54 check_dns now emits the warning and critical thresholds with the performance data
56 FIXES
57 Don't let e.g. check_http's -C option reset SSL version if e.g. -S 1 -C 5 is specified
58 Don't have check_http's -N option expect an argument
59 check_ide_smart could disable offline auto tests but could not re-enable them.
60 For this reason all SMART command modes have been disabled.
61 check_dig: fix wrong IPv6 arguments order (Stéphane Bortzmeyer)
62 check_dig: make sure not to give up too early when a timeout is specified with -t
63 check_log: don't stumble over log lines that include a "%" character
64 check_nt: add UPTIME to perfdata
65 Handle SNMPv3 noAuthNoPriv properly with check_snmp
66 Fix compilation with GnuTLS
68 WARNINGS
69 New default installation prefix: /usr/local instead of /usr/local/nagios
70 check_snmp now evaluates negative values properly, which means it might return CRITICAL
71 in cases where it used to return OK. If this is undesired, the warning/critical
72 threshold(s) must be fixed by specifying e.g. ~:100 instead of 100
73 check_procs now ignores its parent process to avoid unexpected results when invoked via
74 certain shells
75 utils.sh no longer defines ECH
76 check_ide_smart -q/--quiet and -n/--nagios (Nagios-compatible output) are now deprecated
77 but accepted for backward-compatibility
78 check_ide_smart -0/--auto-off, -1/--auto-on and -i/--immediate: options have
79 been disabled because they were broken
80 State retention: the NAGIOS_PLUGIN_STATE_DIRECTORY environment variable has been
81 renamed MP_STATE_PATH. The old variable will continue to work in v2.0.x
82 Add the UID of the invoking user to the state retention file path. This helps solving
83 permission issues when different users run the same plugin
84 check_swap used to allow returning OK on a system without swap when only percent thresholds
85 were used. This is no longer the case and one must now use -n/--no-swap=<state>
86 The Perl and Shell plugins now use the PATH specified via ./configure's --trusted-path
87 option, or "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin" by default
89 1.5 2nd October 2013

109 New check_fping -S option to specify the source IP address
110 New check_fping -I option to specify the interface to bind to
111 Let check_fping support IPv6
112 New check_procs -k option to ignore kernel threads (on Linux)
113 Let check_procs use /proc/<PID>/exe (if available) instead of getpid(2), unless -T is specified
114 Let check_mysql support SSL
115 Let check_mysql add perfromance metrics for all checks
116 New check_mysql -f option to specify a client options file
117 New check_mysql -g option to specify a client options group
118 New check_snmp --offset option to allow for adding/substracting an offset value to sensor data
119 Let check_snmp support an arbitrary number of OIDs

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

295 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
296 You should read the --help output so see which one is suitable for you. check_ntp_peer
297 implement stratum thresholds support (feature request #1703823).
298 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
299 as long as the thresholds range include -1. If no offset threshold is specified
300 and the offset is unavailable, will return UNKNOWN as well.
301 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
302 is "-1" as the default range starts at 0. See Examples in --help output.

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

336 Fix check_smtp's handling of multiple-packet server responses
337 WARNING: Fix for negate which may break existing commands:
338 - stop evaluating command line options through shell twice
339 - enforce a full path for the command to run
340 The "negate" utility can now remap custom states
341 Check_radius now supports radiusclient-ng
342 The (undocumented) positional parameter parsing which check_radius used
343 instead of getopt(3) if 8 arguments were given is no longer available
344 Check_by_ssh now supports multiline output
345 IPv6 support can now be disabled using ./configure --without-ipv6
346 Fix check_ntp now honor ntp flags
348 1.4.9 4th June 2007
