This file documents the major additions and syntax changes between releases. 1.4.14 ... check_users thresholds were not working excatly as documented (>= rather than >) Updated tinderbox_build script to point to new tinderbox server check_ifoperstatus -n flag now works as expected (sf.net #1569488) check_ifoperstatus now supports ifType based lookup for ifIndex check_ups now sends a LOGOUT string (debian bug #387001) 1.4.13 25th Sept 2008 Fix Debian bug #460097: check_http --max-age broken (Hilko Bengen) Optimised pst3 for systems with large number of processes (Duncan Ferguson) Updated Nagios::Plugin to 0.27 Fix Debian bug #479013: check_dig's -l is mandatory now (sf.net #1986306) check_dig now returns CRITICAL instead of WARNING when no answer section is found check_procs now captures stderr in external command and adds to plugin output check_snmp now only prints perfdata for non numeric values (#1867716) check_icmp now supports packet size modification check_http -e now accepts a comma-delimited list of expected status codes (Sven Nierlein) libtap now included with this distribution for easier testing. Run ./configure with --enable-libtap check_ntp_peer/check_ntp_time used to show port in --help but ignored the argument - now implemented Fix possible segfault in check_ntp_peer with deliberately invalid packets 1.4.12 27th May 2008 Added ./check_nt -v INSTANCES to count number of instances (Alessandro Ren) New check_icmp -s option to specify the source IP address check_dns now sorts addresses for testing results for more than one returned IP (Matthias Urlichs) Fix segfault in check_ntp_time and (deprecated) check_ntp (Bug #1862300) check_disk should now work with large file systems (2TB+) on all archs that supports it Fixed check_disk disk usage calculation when using --group=NAME (related to bug #1348746) Fix help text of check_ntp* (Bug #1880095) Fix bugs and flaws in best offset server selection of check_ntp_time and (deprecated) check_ntp check_ntp_peer now checks for the LI_ALARM flag Sync to latest Gnulib (includes new floorf function) check_pgsql now successfully builds with postgres lib v8.3 (Bug #1878972) check_procs now accepts --ereg-argument-array for a regular expression match to the argument array Reverted back to using pst3 for Solaris systems. Fixed issues re: -m64 needed to compile on 64bit systems If applicable, Gettext linked dynamically instead of statically check_dig can now pass arguments to dig by using -A/--dig-arguments (#1874041/#1889453) check_ntp and check_ntp_peer now show proper jitter/stratum thresholds longopts in --help check_dns now allow to repeat -a to match multiple possibly returned address (common with load balancers) check_mysql and check_radius now try clearing password in processlist just like check_mysql_query check_mysql and check_mysql_query now support sockets explicitely (-s, --socket) negate now has the ability to replace the status text as well (-s, --substitute) Added performance data to check_ping (Christian Schneemann) Added support for --extra-opts in all C plugins (disabled by default, see configure --help) Fixed passive option in check_by_ssh On non-skipped stderr, check_by_ssh now returns UNKNOWN or worse (result from command) instead of always UNKNOWN. Fix linking against OpenSSL where libdl is required 1.4.11 13th December 2007 Fixed check_http regression in 1.4.10 where following redirects to relative URLs on virtual hosts failed if both "-H" and "-I" were used Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time. You should read the --help output so see which one is suitable for you. check_ntp_peer implement stratum thresholds support (feature request #1703823). check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000) as long as the thresholds range include -1. If no offset threshold is specified and the offset is unavailable, will return UNKNOWN as well. NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter is "-1" as the default range starts at 0. See Examples in --help output. Fixed broken usage2 in check_snmp and check_cluster check_cluster now accepts all valid characters in its thresholds ("-", "@", "~") Fixed check_disk reporting OK if disk usage grows over 100% (bug #1348746). The problem happens to be in Gnulib but a workaround have been implemented in check_disk.c Fixed check_load argument handling when not passing triplets (bug #1831890) Fixed buffer overflow in check_snmp (CVE-2007-5623) Tinderbox builds now runs tests in a verbose mode Updated Nagios::Plugin to 0.22 VPATH problem fixed for compiling plugins-root 1.4.10 28th September 2007 Fix check_http buffer overflow vulnerability when following HTTP redirects (CVE-2007-5198) check_http now explicitly asks HTTP/1.1 servers to close the connection after completion of the response Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect) is now deprecated. See --help for further information. Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p) A meaningful error message (eg "Stale NFS Handle") is printed if stat fails. New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too. Thus accessibility of remote filesystems can be checked without any threshold comparison. Check_disk's --help now prints some examples for the new features introduced in 1.4.8 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions New check_disk -A option to select all filesystems explicitly WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments Passing -E after -p or -r results in UNKNOWN state, now This is needed due to the new ignore feature Fix check_disk bug when mixing case sensitive and case insensitive regex arguments New check_dhcp -u/--unicast option for emulating a DHCP relay in order to check DHCP servers on remote networks New check_dhcp -m/--mac option which allows for specifying the MAC address to use in the DHCP request The check_dhcp -r and -s options now accept host names, too Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms Fix check_smtp's handling of multiple-packet server responses WARNING: Fix for negate which may break existing commands: - stop evaluating command line options through shell twice - enforce a full path for the command to run The "negate" utility can now remap custom states Check_radius now supports radiusclient-ng The (undocumented) positional parameter parsing which check_radius used instead of getopt(3) if 8 arguments were given is no longer available Check_by_ssh now supports multiline output IPv6 support can now be disabled using ./configure --without-ipv6 Fix check_ntp now honor ntp flags 1.4.9 4th June 2006 Inclusion of contrib/check_cluster2 as check_cluster with some improvements New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh check_snmp now supports Counter64 Fix compilation of check_ldap, check_radius and check_pgsql check_load can optionally divide by number of cpus Fix check_time returning wrong OK when time is before the epoch on some arch Make check_http output more consistent Fix possible check_http segfaults when following HTTP redirects check_snmp don't warn anymore if something is printed on stderr Fix check_tcp segfault when multiple expect strings are given New option for check_tcp: -A/--all to test if all given expect strings match 1.4.8 11th April 2007 Respects --without-world-permissions for setuid plugins check_disk extra options for regex matching of filesystems and grouping of filesystems for collective thresholds Better configure test for mysqlclient availability Various check_ntp fixes 1.4.7 29th March 2007 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris Fixed MKINSTALLDIRS problem in po/ ./configure now detects if possible to compile check_mysql Fixed broken HELO in check_smtp check_icmp now allows to set a minimum number of hosts required for successs (-m) check_icmp fix for *BSD when running for long time check_ping times out 1 second quicker if host is unreachable Root plugins installed with world executable check_sybase from contrib now maintained in NagiosExchange --with-nagios-user/group reinstated ./configure option New --without-world-permissions ./configure option 1.4.6 5th February 2007 Reduced number of DNS lookups in check_ping and netutils.c for IPv6 configurations Fixed compile problems with *BSD re: alloca.h Fixed Solaris problems with check_swap (tested on Solaris 9) Fixed check_swap for HP/UX where swapinfo command was incorrect Fixed check_disk inode threshold checks, regressed at r1.4.4. Fixed crit/warn for check_disk perf data Fixed buffer overflow in check_procs Fixed error handling for UNIX sockets in netutils.c New -q and -o options for check_by_ssh which are handed over to ssh(1) as is Synced with latest GNUlib Fixed check_jabber always returns warning 1.4.5 Fixed bug in perl's is_hostname routine 1.4.4 New C based check_ntp. The perl version is now deprecated. New check_apt plugin Notice: plugins in contrib/ will start to be removed from this distribution. Please check at http://www.nagiosexchange.org for contributed plugins Major bug fixes to check_disk where values were incorrectly calculated and alerted on. check_udp2 removed. check_udp is now linked to check_tcp.c check_mailq now errors if the sub-program run returns non-zero return code. This would appear as if mailqs were okay when the nagios user could not query the mail-queues Compile problems with check_snmp fixed 1.4.3 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install SSL plugins work with gnutls as well as OpenSSL check_mysql_query added to run arbitrary SQL commands, with threshold checking libtool now required for development systems Notice: check_udp (compiled from check_udp.c) will be deprecated in the next release. check_udp2 should be used instead and will be renamed to check_udp 1.4.2 Fix for Redhat ES4 for check_dns and check_dig 1.4 IPv6 support in check_ping, check_by_ssh, check_http, check_ldap, check_smtp, check_tcp Internationalisation support Performance data added to most plugins check_disk now using GNU coreutils code New plugins - check_dhcp, check_icmp contrib/check_citrix has been replaced by contrib/check_ica* (requires packet_utils.pm in libexec) check_http --min changed to --pagesize, added max so min:max in check check_vsz and check_rss deprecated - functionality moved into check_procs check_swap % thresholds changed to measure amount free, instead of amount used check_disk syntax changes for -p, -m/-M, defaults to MB instead of kB check_procs -C expects no path for the command name
