Forking raises a race condition, where the parent might run the
test before the child has had time to fork. If that happens,
an error similar to this is produced:
Failed test 'Output correct'
at ./t/check_procs.t line 32.
'PROCS OK: 0 processes with args 'sleep 7' | processes=0;;;0;'
doesn't match '/^PROCS OK: 1 process?/'
Sleeping a bit should avoid the problem. It might be enough to
sleep less than a second, but perl's built-in sleep function only
supports integer seconds.
In our build environment, the build failed 3 of 4 times before
this patch. After the patch it failed 0 of 7 times.

The SNMPv3 noAuthNoPriv security level, somewhat unintuitively, requires
a security name to be passed along together with the request. Check_snmp
previously did not do this, causing snmpget to throw an error:
"External command error: No log handling enabled - turning on stderr
logging
snmpget: No securityName specified"
This patch fixes the issue by always providing the security name when
noAuthNoPriv is specified.

Also default to "-u test -ptest" which are default MySQL accounts only
missing the prescribed privileges.
The database is no longer specified as it is not used.
If wanted is should be its own parameter/tests.

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.
|
|
- check http had wrong number of skipped tests
- check tcp did not use the 'no internet' flag at all
|
|
also grandparents make this test fail but is not a problem in real live.
NPTest->testCmd uses "sh -c" already, so there is no need to do that twice.

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.

at least on freebsd, there are a processes with state 'S', they always
use two character status.
|
|
|

freebsds ping takes a few seconds till it returns, so a 1 second timeout does
not work for the test.

nc.traditional is available on (at least) ubuntu systems and uses traditional nc syntax

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.

multiple headers have to be set by multiple -k switches. Seperating them
by semicolons is not longer supported as semicolons are valid characters in
http headers.

"./check_tcp -6 -p 80 host" leads to an error:
TCP CRITICAL - Invalid hostname, address or socket: 127.0.0.1
because 127.0.0.1 is the fallback host, the tailing hostname
was ignored.

Fixes for check_apt handling of -i/-e/-c regexps and SECURITY_RE, plus tests

nagios.com seems to have changed their ip address. Also added tests
about -4/-6 option.
|
|
Add a hidden "--input-file" option to check_apt (modelled on
check_procs) so that it can take files with sample apt output as input.
Add tests for my SECURITY_RE fix (debian3) and for the include, exclude
and critical options.

In the C shell and in the Z shell, the "?" character must be quoted or
backslash-escaped in order to use it verbatim. Therefore, a command
such as
check_by_ssh -H test.example.com -l joe echo huh?
might fail, depending on joe's login shell on test.example.com.
Just to make sure, this commit removes most punctuation characters from
our test strings.

Older versions of SQLite3 don't seem to support that.

All tests use sqlite3. A temporary database is created for the purpose of the

This patch adds a check for the certificate cn (hostname) to normal
certificate checks. It returns CRITICAL if th cn is missing, otherwise it
prints it in the normal output.

1. Timetick test could fail with uptime > 115 days. Thresholds are
double type, so it's safe to put a large number even for 32bit systems.
2. Add a test based on an invalid bug report, worthy anyway.
|
|
Original patch to make Timeticks works as in check_snmp v1.4.14, it turns
out is_numeric isn't so useful and treating all types as numeric works
best for backwards-compatibility. This is how it used to work in 1.4.14.
As a special case, I also make calculate_rate look up for numeric values
as it would otherwise return the last value instead.
|
|
Add support for checking the number of usable time sources (i.e., the
number of peers which are classified as so-called "truechimers" by NTP's
intersection algorithm). The new "-m" and "-n" options allow for
specifying the according WARNING and CRITICAL thresholds (and thereby
activating the truechimers check), respectively.
