By default, the Integration Server server.log rotates daily at midnight. If services log large payloads, the server.log can increase rapidly in size. In addition to consuming resources, a large server.log file can be difficult to examine. To avoid this, you can configure Integration Server to rotate the server.log file by size in addition to rotating by day.

Integration Server provides a server configuration parameter that you can use to specify the size limit for the server log. When watt.server.serverlogRotateSize is set to a valid value, Integration Server rotates the server.log when the server.log file size reaches that size or at midnight, whichever occurs first. For example, if watt.server.serverlogRotateSize is set to 100KB and at midnight the server.log file size is 80KB, Integration Server still rotates the server.log file at midnight.

When Integration Server rotates the server.log file, Integration Server renames the current log to use the archive file name and starts a new server.log file. If rotating based on size, the archive file name uses the format server.log.yyyyMMdd.n, where yyyyMMdd is the date the log file was created and n is the number of the log file created that day.
