You can use Log Insight to analyse any unstructured or structured log files.

If the source host has the capability to send log events over either the syslog protocol or HTTP, Log Insight can accept the data. To analyze historic data you can import log files that were archived by Log Insight.

See Import a Log Insight Archive into Log Insight.


Although Log Insight can handle historic data and real-time data simultaneously, you are advised to deploy a separate instance of Log Insight to process imported log files.
