linux snclient nrpe external command arguments not parsed

[Wolverine65]

I'm trying to use the check_logfiles check from omd nagios host with NRPE module enabled on the scnlient agent machines

omd thruk host:

$ /omd/sites/vpe/lib/monitoring-plugins/check_nrpe -H $IP_ADDRESS -t 20 -c check_logfiles rundeck_logfile_scm_failed

snclient agent:

snclient.ini # SNClient v0.33 (Build: 7357817, go1.23.8)

[/settings/NRPE/server]
allow nasty characters = true
allow arguments = true

[/settings/external scripts/scripts]

allow arguments = yes
check_logfiles=scripts/check_logfiles --config $ARGS$

tried all of these ( with and without quotes )

$ARGS$ contains all macros space separated without quotes.
$ARGS"$ contains all macros space separated with quotes.
$ARGSn$ contains the value of the argument at position n.

[check_wrap:74] command before macros expanded: check_logfiles --config '$ARG1$'
[2025-05-23 10:40:18.546][Debug][pid:1275678][check_wrap:76] command after macros expanded: check_logfile --config '' "

resulting outcome should be

check_logfiles --config rundeck_logfile_scm_failed

could you try the latest nightly build? Because we "improved" the macro and args handling since the 0.33 release and there is a good chance this is working much better now.

could you try .../check_nrpe ... -c check_logfiles -a rundeck_logfile_scm_failed with the -a. I guess check_nrpe simply does not submits the argumens otherwise.
