Major changes between "nagios-plugins-linux" versions 23 and 24
-= New Year 2019 release =-
-- Fixes:
* check_cpufreq: the frequences returned by sysfs are in KHz.
This issue has been reported by "sbraz". Thanks!
-- Enhancements

Major changes between "nagios-plugins-linux" versions 22 and 23
-= Korbielow.pl 2018 release =-
-- Enhancements
* New plugin 'check_docker':
This new plugin can be used for:
* checking the total number of running docker containers or the containers
of a given type
* checking the memory usage (alpha!)
* Build system:
* Build the sources with the available compiler's hardening flags.
The following compiler flags are tested/added when available:
* -D_FORTIFY_SOURCE=2 (Buffer overflow checks)
* -fstack-protector-strong or -fstack-protector-all
* -fpie -fPIE (Position Independent Executable support)
* -Wstack-protector
* -Wl,-z,relro (RELRO (read-only relocation))
* -Wl,-z,now
The option `--disable-hardening' disable the attempt to harden
the resulting executables.
* End the ./configure output with a summary of the build options.
* Add the option --enable-werror to ./configure, to make all warnings
as errors. This option is disabled by default.
* Package creation:
* Add Fedora 27 and Fedora 28 to the supported distributions.
* Test framework:
* Some new unit tests have been added.
* lib/container
* lib/url_encode
* tests/testutils
-- Fixes:
* Fix some issues reported by Codacy, Coverity, and LGTM.
-- Experimental
* Add the command line option `--enable-libprocps' that will
link the binaries with the library libprocps newlib instead
of using the internal libraries.
======================================================================
Major changes between "nagios-plugins-linux" versions 21 and 22
-- "Commit 600" release
-- Fixes
* vminfo lib: add the following items to the /proc/vmstat parser:
- vm_pgalloc_dma32
- vm_pgrefill_dma32
- vm_pgscan_direct_dma32
- vm_pgscan_kswapd_dma32
- vm_pgsteal_dma32
- vm_pgsteal_direct_dma
- vm_pgsteal_direct_dma32
The DMA32 memory zone is only available on 64-bit linux
(low ~4GBytes of memory). This patch can slightly modify the value
of the memory counters reported by check_memory.
-- Enhancements
* Fix several warnings reported by Codacy and Codeclimate.
======================================================================
Major changes between "nagios-plugins-linux" versions 20 and 21
-- Enhancements
* check_paging: the command-line option `--swapping-only' has been
added for displaying only the swap reads and writes. The help
message has been updated and improved by added some lines that
explain which kernel variable(s) are selected when a user specify
the warning and/or critical thresholds.
* The Docker-based framework for packaging the Nagios Plugins for
Linux (test-build) supports two new extra distributions:
Debian 9 (Stretch)
Fedora 26
* The test framework (make check) has been reworked and enriched in
new modules:
tests/tsclock_thresholds
tests/tscswch
tests/tsintr
tests/tslibmeminfo_conversions
tests/tslibmeminfo_interface
tests/tslibmeminfo_procparser
tests/tslibmessages
tests/tslibvminfo
tests/tsload_normalize
tests/tsload_thresholds
tests/tspaging
tests/tstemperature
tests/tsuptime
The result of each text execution is now diplayed with colors.
* The code of several plugins has been polished and modularized to
allow testing.
* The glibc function `secure_getenv()' (or `__secure_getenv()' on
Ubuntu, and maybe other distributions) is now used, instead of
`getenv()', in the test code to improve security.
======================================================================
Major changes between "nagios-plugins-linux" versions 19 and 20
-- Security fixes
* Some insecure data handling issues discovered by Coverity in the
new test framework have been fixed.
-- Enhancements
* The Clang Static Analyser can now be executed by running the command
make -C tests check-clang-checker
in the project root directory.
All the warnings spotted by this code analyser have been fixed.
* A new Docker-based framework for packaging the Nagios Plugins for
Linux (rpm and deb packages) is now available.
The supported Linux distributions follow:
CentOS 5/6/7
Debian 6 (Squeeze), 7 (Wheezy), 8 (Jessie)
Fedora 24/25/rawhide
RHEL 5/6/7
* Nagios Plugins for Linux has been Debianized.
* The messages displayed in case of a too large "count" or "delay"
error have been improved.
======================================================================
Major changes between "nagios-plugins-linux" versions 18 and 19
-- Fixes
* check_multipath: recent versions of multipath no longer open a
multipathd socket file in the file system, but instead use an
abstract namespace socket: @/org/kernel/linux/storage/multipathd.
Thanks to Chris Procter "chr15p" for reporting the issue and
creating a pull request.
* check_load: fixed the performance data output
-- Security fixes
check_cpu: fixed coverity 152987 "Untrusted loop bound"
check_cswch: fixed coverity 152985 "Untrusted loop bound"
check_fc: fixed coverity 152984 "Untrusted value as argument"
check_intr: fixed coverity 152986 "Untrusted loop bound"
-- Enhancements
* check_multipath: fixed the long-standing gcc compiler warning:
"dereferencing type-punned pointer might break strict-aliasing
rules [-Wstrict-aliasing]".
This was a false problem, but the code has been modified to quiet
the warning.
* check_multipath: use a larger buffer for queries to make this
plugin working with systems that have lots of mapped disks.
* test-suite: a framework for testing the code (make check) has been
added and some tests are now available.
-- Compatibility issues
* check_multipath: by default the abstract namespace socket
"@/org/kernel/linux/storage/multipathd" is now selected at build
time. If you need to monitor old distributions (RHEL5 and RHEL6
for instance) you need to configure this package as followed:
./configure --with-socketfile=/var/run/multipathd.sock
======================================================================
Major changes between "nagios-plugins-linux" versions 17 and 18
-- Fixes
* check_clock,
check_cpufreq,
check_cswch,
check_intr,
check_multipath,
check_nbprocs,
check_network,
check_tcpcount,
check_users: fix the return code of the warning and critical
case. Thanks Paul Dunkler for pointing out this issue.
* check_cpu: fix the detection of the CPU 64-bit op-mode.
* check_cpu: fix a memory resource leak reported by the Coverity Scan
tool.
* meminfo lib (check_memory): use SReclaimable in cached.
The cached memory is something you can get back and reclaim if
under memory pressure. Make cached only use the reclaimable
component and ignore the unreclaimable values which doesn't make
sense in this context.
======================================================================
Major changes between "nagios-plugins-linux" versions 16 and 17
-- "400th (git) commit" release
-- Enhancements
* check_fc: new plugin for checking the status of the fiber channel
ports.
-- Fixes
* Fix a resource leak in the library 'thresholds'.
* Minor fix in the library 'interrupt'.
======================================================================
Major changes between "nagios-plugins-linux" versions 15 and 16
-- "25 aprile" release
-- Enhancements
* check_cpufreq: new plugin.
* meminfo lib: reduce the memory footprint by not allocating the
variable exported by /proc/memory and not used by any plugin.
* check_cpu: new option '--per-cpu' for checking the CPU utilization
for each CPU. A warning message is returned if at least one CPU
exceeds the warning threshold and no CPU exceed the critical state.
A critical message is returned if at least one CPU exceeds the
critical threshold.
The option '--cpufreq' has been removed because this information is
now provided by the new plugin 'check_cpufreq'.
-- Fixes
* check_multipath: fix the regular expression that catches the failed
paths and that prevented the plugin from working correctly.
* Improved code quality based on the Coverity scan analysis.
* Build system: minor fixes to make the Travis-CI Continuous
Integration work - gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) environment.
Update some obsolete macros used by configure.ac.
Portability has been improved.
======================================================================
Major changes between "nagios-plugins-linux" versions 14 and 15
-- Enhancements
* check_memory / meminfo lib: the command line option '-C|--caches'
now does nothing but is still accepted for compatibility.
The memory usage calculation has been reviewed and is now more
accurate. The changes are based on the (long) discussions and
patches that have been recently posted in the procps mailing list.
* check_memory / meminfo lib: a fall-back has been implemented in
order to provide the memory available counter for the linux kernels
2.6.27 and above,
* check_cpu: add one decimal digit to the counters 'cpu_user',
'cpu_system', 'cpu_idle', 'cpu_iowait', and 'cpu_steal'.
* check_cpu: new command line option '-m|--no-cpu-model' for removing
the cpu model description from the output message.
======================================================================
Major changes between "nagios-plugins-linux" versions 13 and 14
-= Korbielow 2014 release =-
-- Enhancements
* check_users: new '--verbose' mode, for debugging.
* check_uptime: new option '-m|--clock-monotonic' for retrieving the
time of the linux monotonic clock instead of using the system
statistics returned by 'sysinfo()'.
* New library 'xstrtol' containing the function 'strtol_or_err' that
was previosly duplicated in several plugins.
-- Fixes
* check_clock: option '--refclock': validate the input instead of
returning crap when the date format is unsupported.
* check_readonlys: do not dereference a null pointer string in the
output message when no readonly filesystems are detected.
* Minor fixes.
======================================================================
Major changes between "nagios-plugins-linux" versions 12 and 13
-- Enhancements
* The build system, the plugins and libraries are been reworked in
order to support some older Linux kernels and (gcc) compilers.
The "nagios-plugins-linux" can now be compiled and run on older
linux systems, like RHEL 5 (gcc 4.1.2, kernel 2.6.18).
* check_memory: new option '-a|--available' for selecting the kernel
counter 'MemAvailable' instead of the default one (memory used).
This feature requires a Linux kernel 3.14 or better.
For older kernels the plugin falls back to the free memory counter.
-- Fixes
* check_tcpcount: do not exit with 'error opening /proc/net/tcp6'
when the command line option '--tcp6' has not been specified.
* cpustats library: do not exit with an error message if 'softirq'
cannot be found in /proc/stat'. This entry is not provided by old
kernels.
=====================================================================
Major changes between "nagios-plugins-linux" versions 11 and 12
* New plugin 'check_intr'.
* meminfo library: get 'MemAvailable' value from /proc/meminfo
(kernel 3.14+) for a future usage.
* check_cswch: fix the unit displayed in the output message when
'count' is 1.
======================================================================
Major changes between "nagios-plugins-linux" versions 10 and 11
* New plugin 'check_cswch'.
* check_cpu: better output of '--cpuinfo' when a hot pluggable cpu
is offline.
======================================================================
Major changes between "nagios-plugins-linux" versions 9 and 10
* check_temperature: modify the syntax of the switch command
