Composer and Composer runtime will create log files in the Logs folder found in the application folder. The log files come in two formats: text files (.txt), and JSON files (.json)

Log Levels

There are five levels of debug messages:

• Fatal - The application will likely stop working, or a fatal error has occurred that will impact performance and/or output. It is advised to restart the application.
• Error - An error occurred. The application might be able to recover from the error.
• Warning - The application has detected an unexpected event that might impact performance and/or output. The warning might render an error, or the application might continue to operate without issues.
• Information - Normal log information
• Debug - More detailed information primarily used for debugging the application

Log Format

The default log format for Composer looks like this:

[{Timestamp:yyyy-MM-dd HH:mm:ss.fff} [{Level}] [{EventId}] {Message} {NewLine}

The extended log format, with Extended monitoring license enabled, looks like this:

[{Timestamp:yyyy-MM-dd HH:mm:ss.fff} [{Level}] [{EventId}] [{Tag}] [{Version}] {Message} {NewLine}

Log files - Extended Monitoring Enabled

If you have licensed the Extended Monitoring Plugin or are using the Trial version of Composer, you can configure Composer to add additional information to each log line. This information includes Server Label (user-defined information) and Version (application version). This additional information is helpful if running multiple instances of Composer, and collecting log files and metrics. The additional information can be used when searching log files, studying Grafana Dashboards, etc.

Examples

Log line without Server Label and Version:

[2023-10-06 14:16:11.203 [Information] [2001] Application started: VindralComposerRuntime R3 2023, v1.7.8678.19673

Log line with Server Label and Version:

[2023-10-06 14:16:11.203 [Information] [2001] [NICLAS-RYZEN-9] [1.7.8679] Application started: VindralComposerRuntime R3 2023, v1.7.8679.25763

To add Server Label and Version, activate the Add Server Label and Version to Log and Metrics in Settings.
