This adds support for @<range> and makes stuff a bit simpler by removing code
duplications.
Note: Previously, the compatibility code for 'check_procs <warn> <max>'
accepted something like 'check_procs -w 10:-1 -c 10:-1 20 50' as well
(treating it as if '-w 10:20 -c 10:50' was specified). This is no longer the
case ... additional arguments are only used as warn/crit thresholds in case
-w/-c is not specified at all.

The initial file was created in the user's home and later tested in the
doc directory. Instead, just rsync if the file is missing.
Also add some temporary files to gitignore/make clean

Dying without a hint of what went wrong is just plain annoying. With
this patch we at least get a hint.
While at it, we fix the string offset so the output we're interested
in doesn't keep the equal sign that snmpget prints.

Since the state patch introduction, we've been freeing uninitialized
memory in lib/utils_base.c::np_cleanup(), which caused coredumps
with check_snmp when illegal threshold ranges (for example) were
passed, or when we called 'die' without having read any state.
This patch fixes it by replacing the malloc() calls in there (all of
them, since using malloc() is almost always an error) with calloc().
malloc() either doesn't initialize the memory at all, or taints it
with a special marker so it can tell us when we're free()'ing memory
that hasn't been initialized. calloc() explicitly initializes the
allocated memory to nul bytes, which is a zero-cost operation when
we get the memory from the kernel (which alread does that) and almost
always desirable everywhere else.

Once upon a time, check_snmp used to accept inverse ranges in the
format of '2:1' to mean "alert if value is inside this range".
Since commit 7cb3ae09334796f3b54e4e6438e38c2cc679b360, ranges such
as those have instead triggered the error "Range format incorrect"
and resulted in an UNKNOWN warning state. This patch attempts to
fix the situation so that the old-style ranges continues to mean
exactly what the once did and people with lots of snmp checks can
avoid a bazillion false positives from their environments.

This commit add a runtime option to ignore the root-reserved space
when calculating perfdata.
Before / after:
./check_disk -w 2% -c 1% /home
./check_disk -w 2% -c 1% -f /home
DISK CRITICAL - free space: /home 272 MB (1% inode=83%);| /home=17551MB;18401;18589;0;18777
DISK CRITICAL - free space: /home 272 MB (1% inode=83%);| /home=17551MB;17466;17644;0;17823
Well, it doesn't really give me more space :) but the perfdata are a
little bit more coherent.
Note that there are still a rounding issue on the percent calculation
(cf calculate_percent() comments, taken from coreutils 'df' command).
272/17823 -> 1.526%
Since the warning/critical/min/max data are usually not saved in RRD DB,
you can activate the option without seeing landslides in the graphs.

Let OpenSSL load its configuration file. See the OPENSSL_config(3) man
page for details.
(Suggested by Max Kosmach in Debian bug report #689960, forwarded by Jan
Wagner.)

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.

For the default security upgrade detection regular expression, match
"Debian-Security" in package description when it's anywhere after the
first parenthesis (not just the second space-delimited word). For
example:
... (4.0.1-5.4 Debian:6.0.6/stable, Debian-Security:6.0/stable ...

"critical" regular expressions. Instead, check for lines beginning
with "Inst" using strncmp and apply the regular expressions only when
such lines are found.
Fixes Debian bug #522812, along the lines suggested by the bug
submitter, Justin T Pryzby.

Fix the threshold specifications in the example for checking the number
of truechimers.

Mention that the check_ntp_peer plugin checks the stratum of the
synchronization peer, not the stratum of the monitored server itself.
Thanks to Marc Haber for bringing this up on the "nagios-users" mailing
list (Message-ID: <20120722142840.GA6931@torres.zugschlus.de>).

In check_http.c, tabs aren't used for indentation.

The "ssl_version" variable was undeclared when the plugins were compiled
--without-openssl and --without-gnutls.
Bug reported by Michael LaCorte on the "nagiosplug-help" mailing list
(Message-ID: <CCD30C91-A2A8-463A-82A9-F99B54F741D3@gmail.com>).

… thus, treat "elapsed time" and the thresholds as floating point values.
|
|
There is no reasonable default value for that.

This option may be used to specify further connection parameters to be passed
to PQconnectdb(). For example, this may be used to specify a service name in
pg_service.conf to be used for additional connection parameters: -o
'service=<name>' or to specify the SSL mode: -o 'sslmode=require'.
See the chapter "libpq - C Library" in the PostgreSQL manual for details.
|
|
These options are not currently supported.
|
|
PostgreSQL accepts the directory name of its UNIX socket as hostname as well,
e.g. /var/run/postgresql/.
|
|
This is more flexible and the recommended way to connect to a PostgreSQL
database.
Also, the verbose output now includes detailed information about the
connection.
|
|
Previously, "(null)" was printed (when using GNU's libc). This has been
changed to print the empty string instead.
|
|
The query result (the double value of the first column in the first row, to be
precise) will be checked against threshold ranges specified using the -C and
-W options.
Note that this also allows to query PostgreSQL internal values using the
information available from the database daemon's "statistics collector" -- see
the chapter "Monitoring Database Activity" in the PostgreSQL manual for
details.

A recent update removed the declarations for a couple variables in
check_smtp.c that are still being used, which caused a failure
in the compilation of check_smtp.c. This commit restores those variable
declarations so the check_smtp.c will again compile.
|
|
Earlier versions of check_smtp generated an (invalid) "MAIL FROM"
command without arguments by default. These days, a "MAIL FROM" command
is only sent if the --from option is specified.
This commit removes a comment which explains the old behaviour, and it
updates a variable name accordingly.
