Hello again 
After sawing the email I remembered you
I experiemented with an Bash library too of rcon, but after some digging and trying out I was able to write the agent in Python3 for it and got an great output:
<<<rconcheck>>>
[b'hostname: W2TJ Competitive Server
version : 1.37.5.3/13753 1119/7863 insecure [INVALID_STEAMID]
udp/ip : 10.0.7.13:27015
os : Linux
type : community dedicated
map : de_dust2
players : 0 humans, 0 bots (30/0 max) (hibernating)
# userid name uniqueid connected ping loss state rate adr
#end
\x00\x00']
What I’m now struggeling with is, that I hard code the RCON Password:
#!/usr/bin/env python3
from srcds.rcon import RconConnection
import socket
hostname = socket.gethostname()
ip = socket.gethostbyname(hostname)
print ("<<<rconcheck>>>")
try:
conn = RconConnection(ip, port=27015, password='Strongpasswd')
response = conn.exec_command('status')
print (response.replace("\\n","\n"))
except:
print("Something went wrong")
I guess in your checks you were able to put in some placeholders and write the credentials in WATO, didn’t you?
And again, like in TeamSpeak3 I’m stuck at the Check Plugin. I read the docu and read a lot of the check plugin that you wrote for me. Well, It seems that I did something wrong, because my CheckMK doesn’t recognize this check 
#!/usr/bin/env python

'inventory_function': inventory_rconcheck,
'check_function': check_rconcheck,

}
Do you got the time and an idea what went wrong with the CheckPlugin?
Thank in advance!
