Issue/Introduction:

Not seeing Web Server metrics using Web Server PowerPack standalone agent connected to a secure/https Web Server.

The WebServerAgent.log shows message::

[ERROR] [WebServerMonitor] Could not get metrics from server : https://<host> Could be due to unsupported protocol or cipherSuite being used

javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

Cause:

The Web Server has the SSL/TLS 1.0 protocol disabled and only supports the TLS 1.1 and 1.2 protocols.

Environment:

APM 9.x, 10.x

Resolution:

In WebServerConfig.xml change the Web Server definition line to have Protocol="TLS" instead of Protocol="SSL".

Additional Information:

NOTE: Support for the TLS 1.1 & 1.2 protocol is only provided in Web Server Agent 10.2 and later.
