Troubleshooting Response Time Measurement Issues

At times, you may not be able to set response time measurement settings or view RTM data. This section describes situations that might cause RTM issues.

Accessing Variables After Upgrades

If you upgrade PacketWise software, you will not be able to immediately access the new response-time variables introduced in the upgraded software version.

To access the variables, reset the measurement engine after installing the upgrade version.

1. Click setup on the navigation bar.

2. From the Choose Setup Page list, select unit resets.

3. Click reset measurement data.

This rebuilds the measurement database to include the expanded set of variables.

Note: Resetting erases all stored measurement data.

Data for Manually Created Classes

If you manually create a traffic class, you must create a corresponding inbound or outbound class to contain the response-time statistics.

Browser Data Differs From Command-Line Data

When you use the browser to view the Worst Clients or Worst Servers windows, you may see more addresses than when you use the rtm drilldown command.

The rtm drilldown command is designed to suppress hosts that had fewer than N transactions because they might skew the data. To include every host in the rtm drilldown list, set the optional cutoff parameter to 1.

For example:

rtm drilldown /outbound/outside/http 10 1

Graph Issues

Response-time graphs may not generate. This could be caused by one of the following conditions:

• The measurement engine was recently reset and is in the process of restarting.
• There isn't enough data to graph
• A system error has been identified.

The graphing feature requires a minimum number of data points to generate a line graph, a bar chart, or a pie chart. The number of data points is dependent on the graphing period requested and how recently the measurement engine was reset.
