The prior bindRemote function was restricted to IPv4 by explicitly using
address family specific functions as pack_sockaddr_in or unparametrized
gethostbyname. Since Perl 5.14, released in early 2013, there is
IO::Socket::IP, which supports lookups and connects for a dual stacked
network.
By switching the connection establishment code, the plugin is now able
to establish connections to IPv6-only hosts. Furthermore, additional -4
and -6 flags were introduced to enforce a specific address family.

For responding hosts nothing changes:
./check_icmp -H 10.0.0.1
OK - 10.0.0.1 rta 0.336ms lost 0%|rta=0.336ms;200.000;500.000;0; rtmax=0.471ms;;;; rtmin=0.000ms;;;; pl=0%;40;80;0;100
In case the host is down, the performance data now contain 'U' according to:
https://www.monitoring-plugins.org/doc/guidelines.html#AEN201
Old:
./check_icmp -H 10.0.0.99
CRITICAL - 10.0.0.99: Host unreachable @ 10.0.1.138. rta nan, lost 100%|pl=100%;40;80;0;100
Old:
./check_icmp -H 10.0.0.99
CRITICAL - 10.0.0.99: Host unreachable @ 10.0.1.138. rta nan, lost 100%|rta=U;;;; rtmax=U;;;; rtmin=U;;;; pl=100%;40;80;0;100
This confuses some performance graphing tools, ex.: pnp.

* check_disk increase alert precision
Free disk percentage value was rounded to a full integer meaning it alerted about ~1% percent too early. This is about 10GB on a 1TB disk.
The warning and critical thresholds already support float values, so just the percentage calculation needs to be improved.

check_procs: Improve help text, mentioning excluded processes

Also reindent the code, converting stray tabs to 2 spaces.

check_procs: ignore our own children
|
|
On systems with higher core counts check_procs will occasionally see
its own "ps" child process with a high CPU percentage and raise a
false alarm.
Ignoring the child processes of check_procs prevents this from happening.

check_disk: fix ignore-missing in combination with includes (fixes #1963)
|
|
Using --ignore-missing together with regex matching and ignore option lead
to a wrong error message.
./check_disk -n -w 10% -c 5% -W 10% -r /dummy -i /dummy2
DISK UNKNOWN: Paths need to be selected before using -i/-I. Use -A to select all paths explicitly
The use case here is a cluster with fail-over mounts. So it is a valid situation that
the regex match does not find anything in addtition with a ignore which also does not exist.
After this patch:
./check_disk -n -w 10% -c 5% -W 10% -r /dummy -i /dummy2
DISK OK - No disks were found for provided parameters|

Removing translation files
|
|
|
|
Unfortunately there is very less coverage of the translations and
was not very much contribution recently this area.
On the other side, maintaing the po files consumes a significant effort.
For now we drop the translation files, but we can revert this change
anytime in the future.
