Cluster Performance

Question

Cluster Performance I have a client who has 2-web server which are clustered. Two questions...

1. What data makes up the statistics or information you would use to be able to monitor performance or load?

2. Once you have this data identified, how do you know it is time to add a third server?

Answer 1

Uou... no simple question:

• OS memory and CPU statistics
• JVM heap size, CPU usage, GC frecuency
• Balancer logs, session replication stas, bandwith usage

And so on...

It is time to add a 3 server when 2 are well configured and they can not keep up to the expected QoS.

Regards.
