The following section will walk you through four of the many History reports available in order to acquaint you with NV4IP. The reports covered here are as follows:
This is a very rich source of data and you can spend many days exploring and investigating this area. To begin, complete the following steps:
1. Click on the History tab.
2. Click the Base History hyperlink under Workload and Performance. This is the historical version of the real-time report viewed earlier.
3. Return to the History tab and click the FTP Performance Expert hyperlink under Expert Reports to view and work with the FTP Performance Expert. If FTP data has been loaded, you may want to look at some of the reports found in FTP Expert. Start with the Top FTP Users (All Sessions) report. If you have done FTPs from the PC to the host, select Include FTP Server when asked what data to view. Otherwise select Include FTP Client. If you do not know, try selecting the server first.
4. Total FTP Bytes - This report shows any large file/data transfers that have occurred for the selected time period. For example, this report may be used to view FTPs that exceed one gigabyte.
5. Return to the History tab and click the Base History hyperlink and then select the Response Time for Network report. This report shows how peaks vs. average loads are handled in your network. Often, networks may handle normal traffic well but fail in their handling of bursts or large volumes. By viewing this report, you get a sense of how bad the peaks are. You should have the necessary data for this report if you completed the steps for using the Monitor. To determine a pattern, start with 256 byte packets to determine:
· What is the average?
· What is the maximum?
In good networks, sometimes the maximum is 10 times the average. In poorer performing networks, the multiplier may be substantially greater. There have been cases where the maximum has been up to 200 times the average.
