HP XP Array Manager Software - Manual (Page 245)

Monitoring Continuous Access Journal performance
Prerequisites
Make sure that the requirements described in “ Prerequisites for analyzing Continuous Access Journal
performance ” on page 244 are satisfied before using the Replication tab.
You can monitor Continuous Access Journal performance (C/T delta) from the Replication tab. If you
see problems, you can then perform an analysis to discover the root cause.
TIP:
By default, performance data is collected every four hours, and configuration information (including
storage systems, copy pairs, and pair management servers) is refreshed every 24 hours. The
Refresh Performance Data button allows you to do a manual refresh of the performance data, and
displays an option to refresh the configuration as well (Also refresh copy group information).
1. Open the Replication tab.
2. Examine the C/T delta trend in the Cnt Ac-J Performance Analysis window:
• The five copy groups with the largest percentage of C/T delta threshold are displayed.
• The text in the bar graph displays the actual C/T delta and threshold values.
• The default Time Period is one day. Use the range buttons to adjust the view.
• The Copy Groups tab includes a table with copy group information and key usage statistics.
• For reference, the Alerts tab includes a summary of alerts that are created by Replication
Manager.
NOTE:
You cannot change alerts from the Alerts tab. You can modify them only from Replication
Manager.
