Understanding the ProtecTIER Performance Analysis
This
topic explains how to interpret the output of the Performance Analysis
Report.
The Performance Analysis Report parses the long-term statistics from the node and creates easy to read HTML files with the performance information.
Report sections
The report will contain
3 main sections; each section contains a summary of the analysis and
several charts with different information from the node.
| Section | Explanation |
|---|---|
| Repository | This section contains repository information such as allocated, used and fragmented space. |
| Node 1/ Node 2 | This section contains the node specific performance information, such as backup and restore activity, delete, defrag and replication information. |
| Cluster | This section will be created only when the report is executed for both nodes. This section contains cluster wide performance information. |
Charts
Performance analysis charts explain
how the system was working at some specific period of time. Each chart
represents 10 days of information so if the report was executed with
a period of time of one month. There are four possible charts. You
can move between the charts to view and understand system activities.
Each activity on the chart gets a specific color and an axis. For
example, the following chart shows how the allocated space is affected
by the delete operation. Each time a delete operation is executed
the allocated space increases.
