1 This file documents the major additions and syntax changes between releases.
4 Added ./check_nt -v INSTANCES to count number of instances (Alessandro Ren)
5 check_tcp now returns UNKNOWN with invalid hostname
6 New check_icmp -s option to specify the source IP address
8 1.4.11 13th December 2007
9 Fixed check_http regression in 1.4.10 where following redirects to
10 relative URLs on virtual hosts failed if both "-H" and "-I" were used
11 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
12 You should read the --help output so see which one is suitable for you. check_ntp_peer
13 implement stratum thresholds support (feature request #1703823).
14 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
15 as long as the thresholds range include -1. If no offset threshold is specified
16 and the offset is unavailable, will return UNKNOWN as well.
17 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
18 is "-1" as the default range starts at 0. See Examples in --help output.
19 Fixed broken usage2 in check_snmp and check_cluster
20 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")
21 Fixed check_disk reporting OK if disk usage grows over 100% (bug #1348746).
22 The problem happens to be in Gnulib but a workaround have been implemented in check_disk.c
23 Fixed check_load argument handling when not passing triplets (bug #1831890)
24 Fixed buffer overflow in check_snmp (CVE-2007-5623)
25 Tinderbox builds now runs tests in a verbose mode
26 Updated Nagios::Plugin to 0.22
27 VPATH problem fixed for compiling plugins-root
29 1.4.10 28th September 2007
30 Fix check_http buffer overflow vulnerability when following HTTP redirects
31 check_http now explicitly asks HTTP/1.1 servers to close the connection
32 after completion of the response
33 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
34 is now deprecated. See --help for further information.
35 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
36 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
37 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
38 Thus accessibility of remote filesystems can be checked without any threshold comparison.
39 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
40 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
41 New check_disk -A option to select all filesystems explicitly
42 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
43 Passing -E after -p or -r results in UNKNOWN state, now
44 This is needed due to the new ignore feature
45 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
46 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
47 to check DHCP servers on remote networks
48 New check_dhcp -m/--mac option which allows for specifying the MAC
49 address to use in the DHCP request
50 The check_dhcp -r and -s options now accept host names, too
51 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
52 Fix check_smtp's handling of multiple-packet server responses
53 WARNING: Fix for negate which may break existing commands:
54 - stop evaluating command line options through shell twice
55 - enforce a full path for the command to run
56 The "negate" utility can now remap custom states
57 Check_radius now supports radiusclient-ng
58 The (undocumented) positional parameter parsing which check_radius used
59 instead of getopt(3) if 8 arguments were given is no longer available
60 Check_by_ssh now supports multiline output
61 IPv6 support can now be disabled using ./configure --without-ipv6
62 Fix check_ntp now honor ntp flags
65 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
66 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh
67 check_snmp now supports Counter64
68 Fix compilation of check_ldap, check_radius and check_pgsql
69 check_load can optionally divide by number of cpus
70 Fix check_time returning wrong OK when time is before the epoch on some arch
71 Make check_http output more consistent
72 Fix possible check_http segfaults when following HTTP redirects
73 check_snmp don't warn anymore if something is printed on stderr
74 Fix check_tcp segfault when multiple expect strings are given
75 New option for check_tcp: -A/--all to test if all given expect strings match
78 Respects --without-world-permissions for setuid plugins
79 check_disk extra options for regex matching of filesystems and grouping of filesystems
80 for collective thresholds
81 Better configure test for mysqlclient availability
82 Various check_ntp fixes
85 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
86 Fixed MKINSTALLDIRS problem in po/
87 ./configure now detects if possible to compile check_mysql
88 Fixed broken HELO in check_smtp
89 check_icmp now allows to set a minimum number of hosts required for successs (-m)
90 check_icmp fix for *BSD when running for long time
91 check_ping times out 1 second quicker if host is unreachable
92 Root plugins installed with world executable
93 check_sybase from contrib now maintained in NagiosExchange
94 --with-nagios-user/group reinstated ./configure option
95 New --without-world-permissions ./configure option
97 1.4.6 5th February 2007
98 Reduced number of DNS lookups in check_ping and netutils.c for IPv6 configurations
99 Fixed compile problems with *BSD re: alloca.h
100 Fixed Solaris problems with check_swap (tested on Solaris 9)
101 Fixed check_swap for HP/UX where swapinfo command was incorrect
102 Fixed check_disk inode threshold checks, regressed at r1.4.4.
103 Fixed crit/warn for check_disk perf data
104 Fixed buffer overflow in check_procs

107 Synced with latest GNUlib
108 Fixed check_jabber always returns warning

118 Major bug fixes to check_disk where values were incorrectly calculated and alerted on.
119 check_udp2 removed. check_udp is now linked to check_tcp.c
120 check_mailq now errors if the sub-program run returns non-zero return code. This would appear
121 as if mailqs were okay when the nagios user could not query the mail-queues
122 Compile problems with check_snmp fixed
125 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
126 SSL plugins work with gnutls as well as OpenSSL
127 check_mysql_query added to run arbitrary SQL commands, with threshold checking
128 libtool now required for development systems
129 Notice: check_udp (compiled from check_udp.c) will be deprecated in the next release.
