2024-03-18check_ircd: IPv6 support (#1995)alvar1-35/+26
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. > $ netstat -p tcp -ln | grep 6667 > tcp6 0 0 *.6667 *.* LISTEN > $ ./plugins-scripts/check_ircd -H localhost > IRCD ok - Current Local Users: 4 > $ ./plugins-scripts/check_ircd -H localhost -4 > IRCD UNKNOWN: Could not start socket (Connection refused) > $ ./plugins-scripts/check_ircd -H localhost -6 > IRCD ok - Current Local Users: 4

2024-02-23check_disk increase alert precision (#1989)Sven Nierlein2-23/+7
* 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. old: ./check_disk -w 35% -c 20% -p / -f -vvv Thresholds(pct) for / warn: 35.000000 crit 20.000000 calling stat on / For /, used_pct=65 free_pct=35 used_units=286451 free_units=156651 total_units=443102 used_inodes_pct=11 free_inodes_pct=89 fsp.fsu_blocksize=4096 mult=1048576 Freespace_units result=0 Freespace% result=1 Usedspace_units result=0 Usedspace_percent result=0 Usedinodes_percent result=0 Freeinodes_percent result=0 DISK WARNING - free space: WARNING [ / 156651MiB (35% inode=89%)];| /=300365643776B;302006979788;371700898201;0;464626122752 new: ./check_disk -w 35% -c 20% -p / -f -vvv Thresholds(pct) for / warn: 35.000000 crit 20.000000 calling stat on / For /, used_pct=64.649722 free_pct=35.350278 used_units=286464 free_units=156637 total_units=443102 used_inodes_pct=10.016183 free_inodes_pct=89.983817 fsp.fsu_blocksize=4096 mult=1048576 Freespace_units result=0 Freespace% result=0 Usedspace_units result=0 Usedspace_percent result=0 Usedinodes_percent result=0 Freeinodes_percent result=0 DISK OK - free space: / 156637MiB (35.4% inode=90%);| /=300379275264B;302006979788;371700898201;0;464626122752 * check_disk: adjust test case to support float precision

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.

2023-11-27check_disk: fix ignore-missing in combination with includes (fixes #1963)refs/pull/1967/headSven Nierlein2-18/+33
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|

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.
