I’m using Icinga 2 and NSClient++ 0.5 to monitore some windows machines.
Now, I want to monitore a system where NSClient++ 0.3.9 is installed, but it can’t get updated because it is used by someone else for their monitoring.
For me, it wasn’t possible to execute any check on the 0.3.9-client. It always says:
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.
My question: is it generally possible to monitore an NSClient++ 0.3.9 with Icinga2? How did the syntax change between these versions?
Here is a part of NSC.ini from the system with 0.3.9 we want to integrate in our Icinga 2:
These are the settings we’re using normally to connect with our Icinga 2 using 0.5:
allowed hosts =
encoding = UTF8
password = $GEN$
allow arguments = true
allow nasty characters = 1
extended response = 1
insecure = 1
payload length = 8192
ssl options = no-sslv2,no-sslv3
string_length = 8192
use ssl = 1
verify mode = none
Thank you for your help!
