SOLVED

First problem was the service definition were I added a register 0 definition. This is only used for macros.

Service Definition

define service{
use generic-service
name CPU-stats
check_command snmp_cpustats!supersecreto
service_description CPU Stats
host_name nagios02
notification_interval 0
notification_options c,r
notification_period 24x7
}

define service{
use generic-service
name CPU Load
check_command snmp_load!supersecreto!70!90
service_description CPU Load
host_name nagios02
notification_interval 0
notification_options c,r
notification_period 24x7
}

And the second problem was that the in the command definition the -C community parameter is not been taken by the check_snmp command giving a time out

# 'snmp_load' command definition
define command{
command_name snmp_load
command_line /usr/lib/nagios/plugins/check_snmp -H '$HOSTADDRESS$' -C
'$ARG1$' -o .1.3.6.1.4.1.2021.10.1.5.1,.1.3.6.1.4.1.2021.10.1. 5.2,.1.3.6.1.4.1.
2021.10.1.5.3 -w :'$ARG2$',:'$ARG3$',:'$ARG4$' -c :'$ARG5$',:'$ARG6$',:'$ARG7$'
-l load
}


# 'snmp_cpustats' command definition
define command{
command_name snmp_cpustats
command_line /usr/lib/nagios/plugins/check_snmp -H '$HOSTADDRESS$' -C
'$ARG1$' -o .1.3.6.1.4.1.2021.11.9.0,.1.3.6.1.4.1.2021.11.10.0 ,.1.3.6.1.4.1.202
1.11.11.0 -l 'CPU usage (user system idle)' -u '%'
}

After change this and harcode the community everything worked!!!

# 'snmp_load' command definition
define command{
command_name snmp_load
command_line /usr/lib/nagios/plugins/check_snmp -H '$HOSTADDRESS$' -C
supersecreto -o .1.3.6.1.4.1.2021.10.1.5.1,.1.3.6.1.4.1.2021.10.1. 5.2,.1.3.6.1.
4.1.2021.10.1.5.3 -w :'$ARG1$',:'$ARG2$',:'$ARG3$' -c :'$ARG4$',:'$ARG5$',:'$ARG
6$' -l load
}


# 'snmp_cpustats' command definition
define command{
command_name snmp_cpustats
command_line /usr/lib/nagios/plugins/check_snmp -H '$HOSTADDRESS$' -C
supersecreto -o .1.3.6.1.4.1.2021.11.9.0,.1.3.6.1.4.1.2021.11.10.0 ,.1.3.6.1.4.1
.2021.11.11.0 -l 'CPU usage (user system idle)' -u '%'
