59cb851cf5 Plugin lxc: add support for MUNIN_CAP_DIRTYCONFIG 2019-08-12 02:36:01 +02:00

f00f28cf6f Plugin lxc: use functions for top-level activities 
This clarifies the flow of control and allows to use
MUNIN_CAP_DIRTYCONFIG later.

4356a024a7 Plugin lxc: clarify name for function "active_guests" 
Previously a variable and a function used the same name.
This was no problem, but it can cause confusion.

55b881878c Plugin lxc: change the plugin from "bash" to "sh" 
No more bashisms were left.

8b955667c5 Plugin lxc: fix handling of "excludes" parameter 
Previously only the first item in the "excludes" environment variable
was really excluded.

46626b9953 Plugin lxc: simplify implementation of function "active_guests" 2019-08-12 02:36:01 +02:00
Lars Kruse
276e96c0dd Plugin lxc: remove ineffective "sort -u" from function "active_guests" 
The output of "lxc-ls" is not line-splitted.  Thus all active guests
are printed in a single line and "sort -u" (removal of non-unique
entries) had no effect.

da8a74fdcb Plugin lxc: omit output of "max" if the network interface speed is unknown 
The "U" value is not defined for the "max" field.

0d593014b4 Plugin lxc: fix printing of "${graph_period}" 
This specific text token ("${graph_period}") is interpreted by munin and
should not be interpreted by the shell.  Thus it needs to be escaped.

e91f7ecba7 Plugin lxc: remove ineffective usage of "bc" 
The command "wc -w" already outputs the final result.
Thus we do not need this command (and do not have to depend on it).

d415877cdc Plugin lxc: explicitly assign all accepted environment variables 2019-08-12 02:36:01 +02:00
Lars Kruse
ec3a7f4045 Plugin lxc: function "lxc_count_processes" now outputs its result 
Previously the result was returned as the exit code of the function
(which would prevent the usage of "set -e").
Additionally the fallback value that was previously calculated outside
of the function is now part of it.

9af96d2c60 Plugin lxc: draw stacked RAM graphs by default 
Previously "ram_display_stacked" defaulted to "false" (non-stacked
graphs).  The new default should be suitable for most situations.

ab6f4e3c6e Plugin lxc: fix configurable RAM graphing 
Previously (before the multigraph conversion) the configuration setting
for "lxc_ram" was called "areastack".  The multigraph conversion
documented a new configuration setting "ram_areastack", but it was not
used, yet.
Thus we can switch to a more descriptive name: "ram_display_stacked".
