We have a Nagios 3.0.6 / NSClient++ 0.3.9 implementation with more than 600 hosts and 7000 services.
We intend to upgrade to Nagios 4 but not immediately.
Meanwhile, we would like to solve some problems, mainly about CheckEventLog, but we are not able to access documentation about NSClient++ 0.3.9.
Can you help us?
Thanks in advance!
