The Introscope EM is unable to send alerts / SNMP traps to the APM connector when the Webview process is running in a separate server
The problem affects any pre APM 9.1.5 version using any Catalyst APM Connector version.
In the EM log you will see the below exception:
[ERROR] [Alarm Pooled Worker] [Manager.SNMPAlertAction] Failed to send SNMP trap due to exception: Socket problem: host=<EM IP address>, port=6162, bindAddr=<Webview IP address> Cannot assign requested address: Cannot bind
Solution / workaround:
For customer using any pre Introscope 9.1.5: You need to install webview in the same server as the Introscope Enterprise Manager.
The problem is resolved in 9.1.5 and onward versions. A new field has been added to configure the Introscope Enterprise Manager and Webview servers separately.
