1 This file documents the major additions and syntax changes between releases.
3 1.4.12 or 1.5 ??
4 Added ./check_nt -v INSTANCES to count number of instances (Alessandro Ren)
5 New check_icmp -s option to specify the source IP address
6 check_dns now sorts addresses for testing results for more than one returned IP (Matthias Urlichs)
7 Fix segfault in check_ntp_time and (deprecated) check_ntp (Bug #1862300)
8 check_disk should now work with large file systems (2TB+) on all archs that supports it
9 Fixed check_disk disk usage calculation when using --group=NAME (related to bug #1348746)
10 Fix help text of check_ntp* (Bug #1880095)
11 Fix bugs and flaws in best offset server selection of check_ntp_time and (deprecated) check_ntp
12 check_ntp_peer now checks for the LI_ALARM flag
13 Sync to latest Gnulib (includes new floorf function)
14 check_pgsql now successfully builds with postgres lib v8.3 (Bug #1878972)
15 check_procs now accepts --ereg-argument-array for a regular expression match to the argument array
16 Reverted back to using pst3 for Solaris systems. Fixed issues re: -m64 needed to compile on 64bit systems
17 If applicable, Gettext linked dynamically instead of statically
18 check_dig can now pass arguments dig by using -A/--dig-arguments (#1874041/#1889453)
19 check_ntp and check_ntp_peer now show proper jitter/stratum thresholds longopts in --help
20 check_dns now allow to repeat -a to match multiple possibly returned address (common with load balancers)
21 check_mysql now try clearing password in processlist just like check_mysql_query
22 check_mysql and check_mysql_query now support sockets explicitely (-s, --socket)
23 negate now has the ability to replace the status text as well (-s, --substitute)
25 1.4.11 13th December 2007
26 Fixed check_http regression in 1.4.10 where following redirects to
27 relative URLs on virtual hosts failed if both "-H" and "-I" were used
28 Merged two new checks that deprecates check_ntp: check_ntp_peer and check_ntp_time.
29 You should read the --help output so see which one is suitable for you. check_ntp_peer
30 implement stratum thresholds support (feature request #1703823).
31 check_ntp now returns UNKNOWN instead of WARNING if jitter is unavailable (jitter=-1.000000)
32 as long as the thresholds range include -1. If no offset threshold is specified
33 and the offset is unavailable, will return UNKNOWN as well.
34 NOTE: If jitter thresholds are specified as integers it will return CRITICAL if jitter
35 is "-1" as the default range starts at 0. See Examples in --help output.
36 Fixed broken usage2 in check_snmp and check_cluster
37 check_cluster now accepts all valid characters in its thresholds ("-", "@", "~")
38 Fixed check_disk reporting OK if disk usage grows over 100% (bug #1348746).
39 The problem happens to be in Gnulib but a workaround have been implemented in check_disk.c
40 Fixed check_load argument handling when not passing triplets (bug #1831890)
41 Fixed buffer overflow in check_snmp (CVE-2007-5623)
42 Tinderbox builds now runs tests in a verbose mode
43 Updated Nagios::Plugin to 0.22
44 VPATH problem fixed for compiling plugins-root
46 1.4.10 28th September 2007
47 Fix check_http buffer overflow vulnerability when following HTTP redirects (CVE-2007-5198)
48 check_http now explicitly asks HTTP/1.1 servers to close the connection
49 after completion of the response
50 Check_ldaps' guessing which secure method to use (starttls vs. ssl on connect)
51 is now deprecated. See --help for further information.
52 Check_disk now calls stat() on all filesystems to check. (Old: only the ones selected using -p)
53 A meaningful error message (eg "Stale NFS Handle") is printed if stat fails.
54 New check_disk option -L: Only check local filesystems, but call stat() on remote ones, too.
55 Thus accessibility of remote filesystems can be checked without any threshold comparison.
56 Check_disk's --help now prints some examples for the new features introduced in 1.4.8
57 New check_disk -i/-I option to ignore pathes/partitions based on regular expressions
58 New check_disk -A option to select all filesystems explicitly
59 WARNING: check_disk's -E option must now be passed before -p or -r/-R arguments
60 Passing -E after -p or -r results in UNKNOWN state, now
61 This is needed due to the new ignore feature
62 Fix check_disk bug when mixing case sensitive and case insensitive regex arguments
63 New check_dhcp -u/--unicast option for emulating a DHCP relay in order
64 to check DHCP servers on remote networks
65 New check_dhcp -m/--mac option which allows for specifying the MAC
66 address to use in the DHCP request
67 The check_dhcp -r and -s options now accept host names, too
68 Fix possible check_icmp bus errors on some (non-x86/AMD64) platforms
69 Fix check_smtp's handling of multiple-packet server responses
70 WARNING: Fix for negate which may break existing commands:
71 - stop evaluating command line options through shell twice
72 - enforce a full path for the command to run
73 The "negate" utility can now remap custom states
74 Check_radius now supports radiusclient-ng
75 The (undocumented) positional parameter parsing which check_radius used
76 instead of getopt(3) if 8 arguments were given is no longer available
77 Check_by_ssh now supports multiline output
78 IPv6 support can now be disabled using ./configure --without-ipv6
79 Fix check_ntp now honor ntp flags
81 1.4.9 4th June 2006
82 Inclusion of contrib/check_cluster2 as check_cluster with some improvements
83 New/improved -E/--skip-stderr and -S/--skip-stdout options for check_by_ssh
84 check_snmp now supports Counter64
85 Fix compilation of check_ldap, check_radius and check_pgsql
86 check_load can optionally divide by number of cpus
87 Fix check_time returning wrong OK when time is before the epoch on some arch
88 Make check_http output more consistent
89 Fix possible check_http segfaults when following HTTP redirects
90 check_snmp don't warn anymore if something is printed on stderr
91 Fix check_tcp segfault when multiple expect strings are given
92 New option for check_tcp: -A/--all to test if all given expect strings match
94 1.4.8 11th April 2007
95 Respects --without-world-permissions for setuid plugins
96 check_disk extra options for regex matching of filesystems and grouping of filesystems
97 for collective thresholds
98 Better configure test for mysqlclient availability
99 Various check_ntp fixes
101 1.4.7 29th March 2007
102 check_procs uses /usr/ucb/ps if available - fixes pst3 problems on Solaris
103 Fixed MKINSTALLDIRS problem in po/
104 ./configure now detects if possible to compile check_mysql
105 Fixed broken HELO in check_smtp
106 check_icmp now allows to set a minimum number of hosts required for successs (-m)

136 check_udp2 removed. check_udp is now linked to check_tcp.c
137 check_mailq now errors if the sub-program run returns non-zero return code. This would appear
138 as if mailqs were okay when the nagios user could not query the mail-queues
139 Compile problems with check_snmp fixed
141 1.4.3
142 Setuid plugins (check_dhcp, check_icmp) separated into plugins-root/. Run make install as root to install
