You can find the active checks in /omd/sites/check_mk/lib/nagios/plugins
You can execute an active check over cli as well.

-H
specify a target
[-4|-6]
Use IPv4 (default) or IPv6 to communicate with the targets
-w
warning threshold (currently 200,000ms,40%)
-c
critical threshold (currently 500,000ms,80%)
-s
specify a source IP address or device name
-n
number of packets to send (currently 5)
-i
max packet interval (currently 80,000ms)
-I
max target interval (currently 0,000ms)
-m
number of alive hosts required for success
-l
TTL on outgoing packets (currently 0)
-t
timeout value (seconds, currently 10)
-b
Number of icmp data bytes to send
Packet size will be data bytes + icmp header (currently 68 + 8)
-v

Notizen:
The -H switch is optional. Naming a host (or several) to check is not.
Threshold format for -w and -c is 200.25,60% for 200.25 msec RTA and 60%
packet loss. The default values should work well for most users.
You can specify different RTA factors using the standardized abbreviations
us (microseconds), ms (milliseconds, default) or just plain s for seconds.
The -v switch can be specified several times for increased verbosity.
