2. Click on "Monitor" on the left side to access the "Monitor" menu.

3. In the "Monitor" menu, click on "System Statistics."

4. The "System Statistics" page appears.

See the detailed information about the statistics panes below:

• Service Summary
• Server Information
• Response Time Graph
• Memory Graph
• Statistics Configuration Panel

Service Summary

This panel provides the following information:

• Average Response Time - The average amount of time taken by the mediation channel to mediate a message (in milliseconds).
• Minimum Response Time - The least amount of time taken by the mediation channel to mediate a message (in milliseconds).
• Maximum Response Time - The greatest amount of time taken by the mediation channel to mediate a message (in milliseconds).
• Total Request Count - The total number of messages received and mediated through the mediation channel.
• Total Response Count - The total number of messages send and mediated through the mediation channel.
• Total Fault Count - The number of messages that triggered faults while being mediated through the channel.
