Health Monitor issue
I am facing a weird issue. We renewed our SSL certificate and our health monitor uses this renewed certificate. Post renewal , our pool member went down. For Tshooting, i enabled monitor logging and the weird part is LTM was not showing any logs in the /var/log/monitor path. So i tried to debug manually by telnetting to the server port and issued the GET string commands, but as soon i paste it, the cli closes the connection (not sure why??)
String in health montior : GET /keepAlive.html\r\n HTTP/1.1\r\nHost: \r\nConnection: close\r\n\r\n
1) [Active F5] # telnet 10.177.222.35 15000
Connected to 10.177.222.35.
Escape character is '^]'.
GET /keepAlive.html HTTP/1.1 (As soon as i put this line, immediately connection closes)
Host: Connection closed by foreign host
2) I tired another method, through openssl
openssl s_client -connect 10.177.222.35:15000
GET /keepAlive.html HTTP/1.1
I get a 400 bad request.
So kinda confused, if i am doing anything wrong. I more interested in the first one why the connection closes as soon as i paste it.
Note : Reverted to old certificate and the Pool came up. And after this only the montior logging started to work. Now even after the pool member is up, i tried the above methods, and i still get the same results.
We are checking internally on the certificate, why this is happening, as its the same cert , just the validity is extended . But i am concerned about the montior tshoot steps i did.
