Network Traffic Report
Published : April 8, 2005 | Updated : August 17, 2005
The Network Traffic Report provides network traffic information for synchronization jobs. It also charts data transmission and job duration, and provides information about data throughput. The data is collected per file server and aggregated for all file servers or per protection group and aggregated for all protection groups.
The first page of the report, the summary page, shows network traffic statistics for all file servers or protection groups at a file server or protection group level, as specified in the report parameters. Subsequent pages, the detailed pages, show network traffic details for each file server or protection group at a volume level.
Frequently asked questions
When you review the data in the Network Traffic Report, you may have questions about how to use the data or interpret the report.
How can I stabilize the average job duration if it is increasing?
If network bandwidth throttling is enabled, you can try increasing the maximum bandwidth percentage or you can disable the network bandwidth throttling option to determine if this solves the problem. Check subsequent Network Traffic Reports to see if job duration stabilizes. For more information, see How to configure advanced options.
What does average data transferred mean?
The data transferred statistics indicate how much replication or synchronization data is moving through the network.
Do the ranking tables include data for all file servers, protection groups, or volumes?
No, the ranking tables on the summary page include data for only the top 10 file servers or protection groups and the detail pages show only the top 10 volumes.
How can I use the statistics in the ranking tables?
The Total Data Transferred table indicates the amount of data transferred for the reported time period. The Average Weekly Data Change Rate table indicates the most active file server, protection group, or volume in terms of data change.
How is the weekly data change rate calculated?
The weekly data change rate is the ratio of the size of synchronization data transferred to the size of the data (or volume) being protected, expressed as a percentage.
Does the report include a daily data change rate?
No, the report provides a weekly data change rate for all granularity options (weekly, monthly, quarterly, annually). To calculate an approximate daily data change rate, divide the weekly data change rate by seven.
Should I do anything if the data change rate is high?
Based on sample measurements, an average daily change rate of more than 10 percent is high and can lead to synchronization failures. If the data change rate is high, make sure that there is enough disk space in the synchronization log on the file server to track data changes. For more information, see How to modify disk allocation. As a precautionary measure, you can also enable nearly-continuous synchronization, if you are not already doing so. For more information, see How to modify protection options.
