WebMeter then generates the performance report based upon the parameters you configured. The performance report is displayed on 3 separate tabs - dashboard, history and detail. Each tab provides different views of the performance you experienced, within the scope of the report parameters. For example, if you specified a particular date range and URL pattern, these views will be generated over the performance data that matches these requirements. The sections that follow describe in more detail the information presented in the performance report tabs.
performance data on two key web metrics. These are bandwidth and latency. Bandwidth is important as it is the major factor in how long it takes to upload and download data. Latency is important as it is the major factor in the responsiveness of your browsing experience (or SaaS functionality).
The WebMeter performance report provides a dashboard showing a summary of these performance metrics, a history of the recorded performance over time and a detailed table of the data that forms the basis of the performance report. To create a performance report follow these steps:
Figure 1download performance, upload performance and the latency that you experienced within the scope of the report parameters.
Download performance is measured in Mbit/s. Each gauge for this statistic (best, worst and average) has a red, amber and green color scheme to indicate the level of performance achieved. In Figure 2 below, we can see that the best download performance achieved was 5.63 Mbit/s out of a potential maximum of 8 Mbit/s. This maximum was specified during installation and can be configured as your ISP or network connections change.
You will note from Figure 2 that the worst download performance was 0 Mbit/s. This can happen when WebMeter did not have appropriate data to calculate the statistic or the figure was so low that it does not register on the scale being used (i.e. Mbit/s).
Upload performance is measured in Mbit/s. Each gauge for this statistic (best, worst and average) has a red, amber and green color scheme to indicate the level of performance achieved. WebMeter's gauges need to cover both symmetrical (e.g. SDSL) and asymmetrical (e.g. ADSL) connectivity so does not alter the red, amber, green scales on upload to reflect the reduced capacity that is usual in domestic ADSL connections. In Figure 2 above, we can see that the best upload performance achieved was 0.16 Mbit/s out of a potential maximum of 8 Mbit/s.
Latency is measured in milliseconds. Each gauge for this statistic (best, worst and average) has a red, amber and green color scheme to indicate the level of performance achieved. The scale used for this colour scheme is based on reasonable thresholds that hold for the vast majority of Internet connectivity. In the example of Figure 2 a respectable 78 milliseconds latency was the best achieved with the worst being 13 seconds.
download, upload and the latency within the scope of the report parameters. A separate graph is presented for each of these three metrics, only download speed is fully illustrated in Figure 3.
Each graph allows you to drill into detail by clicking one of the "zoom" options in the top left hand corner. As you can see in Figure 3 this zoom resolution goes from 1 minute to 5 minutes and all the way to 6 months and 1 year. This can be useful when attempting to track down a performance issue which occurred at a particular point in the past.
The table is paginated so that you can conveniently click though transactions a batch at a time. Also, it is possible to order transactions by individual column values by clicking on any column. For example, you can order transactions by request size by clicking on the "Request" column.
At the bottom left hand corner of the table there is a button which allows you to export all data in the table as a CSV file. On windows platforms, this will allow you to open data in Microsoft Excel for further analysis and visualisation.
