I have a monitor server ubuntu and install icinga and check_nrpe on it.
I want to monitor many window server and install NSClient++ on them.
All thing is ok.
But recently, monitor server can't check window server and receive message: "CHECK_NRPE: Socket timeout after 10 seconds.".
I investigate nsclient.log and have many error:
"error:c:\source\master\include\socket/connection.hpp:276: Failed to establish secure connection: short read: 219"
Sometime It starts working again, but will fail again after a few minutes or so.
Please help me to solve this issue.
