Patch of check_ping that allows it to gracefully handle when ping outputs
to stderr "Warning: time of day goes back (-XXXXus), taking countermeasures."
Closes: #809 and #1195
The more important change: A fix for a bug which caused the check_ntp_time
and check_ntp_time check to always take the first response from ntp and not
the avarage since "j" is not increased anywhere. "i" should be used there
instead.
Partly Closes#956 and Closes#1166Closes: #1089
Each S.M.A.R.T. attribute is compared against a threshold. If it is LESSTHAN
that threshold an error is reported. This patch fixes the problem, that
attribute values EQUAL to the threshold are reported as error, which is wrong.
Only LESSTHAN the threshold is an error.

My SSD has some attributes which value and threshold are "0". Without the patch
this is reported as errornous.

check_ide_smart could disable offline auto tests but could not re-enable
them. For this reason all SMART command modes have been disabled
The disabled commands are -0/--auto-off, -1/--auto-on and
-i/--immediate
check_ide_smart was originally a smard control utility later converted
to a monitoring plugin. the -n option (Nagios check) should therefore be
the default.
This patch deprecates the -n and -q switches, and make the other
switches return nagios-compatible output (they are most likely used in
eventhandlers, but returning nagios-compatible output makes it clear and
easy to handle the return status)
while compiling i keep receiving an warning statement as follow:
warning: zero-length gnu_printf format string
using an unorthodox method to remove them

Install into /usr/local instead of /usr/local/nagios by default, in
order to comply with the Filesystem Hierarchy Standard (FHS) and
presumably the expectations of most users.
Changes to non-network checks for clarity on timeout value. Adapted from pull request #1209 tracker from user awiddersheim. (Closes: #1209)
Files: check_apt.c, check_disk.c, check_procs.c, negate.c
Addition of timeout message for non-network plugins(UT_PLUG_TIMEOUT), and alteration of UT_TIMEOUT to UT_CONN_TIMEOUT for networked checks. Alteration of pull request #1209 tracker by user awiddersheim.
This is an initial take at renaming the project to Monitoring Plugins.
It's not expected to be fully complete, and it is expected to break
things (The perl module for instance). More testing will be required
before this goes mainline.
If you specify -S1 -C 30... The -C option will reset the ssl_version to 0. This is not a good thing.
Instead we set the default to 0 and retain the version when later args are passed.
Fix the problem that check_http's "-N" option expects an argument
although it shouldn't. The corresponding long option ("--no-body")
wasn't affected.
This error was introduced in ee3c4014d5.
Thanks to Kerry Hughes for reporting it on the devel@ list.
This fixes an issue that appears when running check_procs over NRPE,
where the default shell is configured to (for example) dash, as is the
case on Debian.
dash (and tcsh, and mksh, and probably others), when invoked with -c forks an additional process
to execute the argument string. Contrast this with bash, which does not
do this, provided that the argument string simply can be exec()'d as-is.
To demonstrate:
$ bash -c pstree
init─┬ ..
...
├─sshd─-─sshd───pstree
versus
$ dash -c pstree
init─┬ ..
...
├─sshd─-─sshd───dash───pstree
The consequence of this fork is that the following invocation:
/opt/plugins/check_procs -a init
will result in this output:
PROCS OK: 2 processes with args 'init' | processes=2;;;0;
because the check_procs, in addition to finding the actual init process,
finds its parent shell as well.
This example is a bit contrived, but I think it illustrates the
point.
This wouldn't really be a problem, and normally isn't, if it weren't
for the fact that NRPE uses a call to popen() which does exactly the
above (executes '/bin/sh -c ...'), causing inconsistent behaviour
between distributions and much confusion for end users.
The argument may be made that the dash process spawned by NRPE is just a
process like any other, and should therefore be included in the process
count just like any other. However, this is not very intuitive, because
of the previously mentioned inconsistencies.
The argument might also well be made that we're _never_ interested in the
immediate ancestor of the plugin, and while it is unknown how many
installations have already made the necessary modifications to their
setups to make up for the fact that the plugin behaves the way it does,
it is not deemed worthwhile to entertain such workarounds.
Thus, this patch ignores the parent process.

if check_imap expects a string that never occurs, it currently waits forever
because thats how the imap protocoll works. Use a receive timeout in that case
so we can exit early with a proper error message.
check_load parses load from the uptime command if no proc filesystem is available. Seems
like there are at least 2 different uptime outputs.

older netcats do not understand -p, they expect host and port as additional argument.
This is backwards compatibel to newer clients. Also support netcat instead of nc.
