1 This file documents the major additions and syntax changes between releases.
5 New check_hpjd -p option for port specification (abrist)
6 New ./configure --with-qmail-qstat-command option to specify the path to
11 check_mailq now supports auto detection of qmail, postfix, exim and nullmailer with
13 check_ide_smart now defaults to plugin output, original output appended with -v
14 Extra-Opts are now enabled by default, see:
15 https://www.monitoring-plugins.org/doc/extra-opts.html
16 check_swap now supports a configurable state when there is no swap
17 check_radius now supports the FreeRADIUS Client library
18 New check_mysql_query -f option to specify a client options file
19 New check_mysql_query -g option to specify a client options group
20 Add performance data to check_mysql_query
21 New check_file_age -i/--ignore-missing option to return OK on nonexistent files
22 Make check_ping, check_users, and check_disk work on Windows

27 Don't let e.g. check_http's -C option reset SSL version if e.g. -S 1 -C 5 is specified
28 Don't have check_http's -N option expect an argument
29 check_ide_smart could disable offline auto tests but could not re-enable them.
30 For this reason all SMART command modes have been disabled.
31 check_dig: fix wrong IPv6 arguments order (Stéphane Bortzmeyer)
32 check_dig: make sure not to give up too early when a timeout is specified with -t
33 check_log: don't stumble over log lines that include a "%" character

35 Handle SNMPv3 noAuthNoPriv properly with check_snmp
36 Fix compilation with GnuTLS
39 New default installation prefix: /usr/local instead of /usr/local/nagios
40 check_snmp now evaluates negative values properly, which means it might return CRITICAL
41 in cases where it used to return OK. If this is undesired, the warning/critical
42 threshold(s) must be fixed by specifying e.g. ~:100 instead of 100
43 check_procs now ignores its parent process to avoid unexpected results when invoked via
45 utils.sh no longer defines ECH

57 option, or "/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin" by default

79 New check_fping -S option to specify the source IP address
80 New check_fping -I option to specify the interface to bind to
81 Let check_fping support IPv6
82 New check_procs -k option to ignore kernel threads (on Linux)
83 Let check_procs use /proc/<PID>/exe (if available) instead of getpid(2), unless -T is specified
84 Let check_mysql support SSL
85 Let check_mysql add perfromance metrics for all checks
86 New check_mysql -f option to specify a client options file
87 New check_mysql -g option to specify a client options group
88 New check_snmp --offset option to allow for adding/substracting an offset value to sensor data
89 Let check_snmp support an arbitrary number of OIDs
90 Let check_ide_smart support NetBSD
93 Change the MAIL FROM command generated by check_smtp to be RFC compliant
94 Fix compilation of check_http without SSL support
95 Fix check_snmp reversed threshold ranges (backward-compatibility)
96 Fix check_snmp memory violation when using more than 8 oids (Robin Sonefors)

99 Fix check_apt handling unknown exit codes from apt-get (Richard Leitner)
100 Fix deprecated imports of check_nmap.py (Fabio Rueda)
103 check_http behaviour of -k/--header changed since it does not seperate multiple headers by semicolons anymore. Use multiple -k switches instead.
104 check_http's --proxy_authorization option is now called --proxy-authorization (it was always documented this way)

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

298 This is needed due to the new ignore feature

309 - enforce a full path for the command to run
310 The "negate" utility can now remap custom states
311 Check_radius now supports radiusclient-ng
312 The (undocumented) positional parameter parsing which check_radius used
313 instead of getopt(3) if 8 arguments were given is no longer available
314 Check_by_ssh now supports multiline output
315 IPv6 support can now be disabled using ./configure --without-ipv6
316 Fix check_ntp now honor ntp flags

373 check_udp2 removed. check_udp is now linked to check_tcp.c
374 check_mailq now errors if the sub-program run returns non-zero return code. This would appear
375 as if mailqs were okay when the nagios user could not query the mail-queues
376 Compile problems with check_snmp fixed
379 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
