Working with Multiple Instances of a Web Server

Information about the general configuration of the Sensor with one web server instance running on a web server.

In this scenario, a single web server instance is writing data to the memory mapped queue file, which is read by the transmitter and sent to the data workbench server.

When Sensor is installed on a web server that is running multiple collector instances, you can configure it one of two ways:

• You can have all of the collector modules share one queue file.

  When using a single queue file, the management, configuration, and administration is somewhat simplified because the architecture itself is less complex. However, with a single queue file, the entire web server, regardless of the number of instances, is identified as WEB1.

• You can replicate the above architecture multiple times and have each web server instance have a separate queue file.

  This enables you to identify each of the web server instances uniquely. In other words, the identification of the web server (and the corresponding SensorID in the Sensor configuration) is a function of this configuration.

In any case, the data still has all of the host name information so that you can distinguish between www.client.com, www2.client.com, and so forth. The correct configuration is determined by the analysis goals and whether the analysts need to segment the data based on a specific instance running on a web server.
