The license server log file

A good source of information about a running CLC License Server is the log file. It contains information about the license server software itself (e.g. start up, shutdown, version, location of the configuration file, etc.) as well as about the licenses available, and the usage of those licenses. By default, the log file is created anew when the CLC License Server is started up.

The log file is a text file called licenseserver.log and is located in the installation area of the CLC License Server. It can be viewed directly using standard tools for reading text files, or it can be viewed and searched using the the LM-X License Server Client described in section The LM-X Graphical License Server Client.

The name and location of the log file, and aspects of its contents, can be customized as described in section 3.1.

The log file can be used for generating license usage statistics directly, but for this purpose, the LM-X License Server Client or the XML output that can be generated using the LM-X End User Utility tool, described in XML format status information may be of interest.

The top of a CLC License Server log file is shown below. This example information is from a server running on macOS, but the output looks similar on all platforms. In this case, two license files were found in the licenses folder, and two licenses are available, one for the CLC Genomics Workbench and one for the CLC Microbial Genomics Module.
