Hello, I've ran into a strange behaviour, a nagios plugin does not execute correctly when called from icinga2, but is OK from command line.
The check is (cmk_load.pl and check_mk_agent.pl are perl scripts of mine):
> object CheckCommand "Check_Load" {
> import "plugin-check-command"
> command = [ PluginDir + "/cmk_checks/cmk_load.pl" ]
> arguments = {
> "-H" = "$address$"
> "-w" = "$warn$"
> "-c" = "$crit$"
> "-vd" = ""
> }
>
> vars.warn = "4,4,4"
> vars.crit = "8,8,8"
> }
When running from command line *as icinga user* it is OK :
> # su icinga
> bash-4.2$ /usr/lib64/nagios/plugins/cmk_checks/cmk_load.pl -vd
> DEBUG: $VAR1 = [
> '0.10 0.11 0.11 1/302 31501 2'
> ];
>
> CMK_LOAD OK - load average 0.10, 0.11, 0.11|load1=0.100;1.000;5.000;0;
> load5=0.110;1.000;5.000;0; load15=0.110;1.000;5.000;0;
But inside icinga, I got this result :
> DEBUG: $VAR1 = undef;
> Use of uninitialized value $load_datas in split at
> /usr/share/perl5/check_mk_agent.pm line 132.
> Use of uninitialized value $l1 in numeric gt (>) at
> /usr/share/perl5/check_mk_agent.pm line 134.
> Use of uninitialized value $l5 in numeric gt (>) at
> /usr/share/perl5/check_mk_agent.pm line 134.
debug.log show me that the plugin is called with the correct parameters.
I have an idea of what fails (DEBUG: $VAR1 = undef; is self
explanatory), but I don't have a clue about how to debug it, aside from
running from cli as user icinga, which does not fail...
If you're curious, the full (dirty) code is here :

Thanks for any help,
Cheers,
