This video will show how to configure MikroTik WebProxy Log Analyzer to analyze MikroTik proxy user's activity. MikroTik RouterOS generally logs various system events and status information. Logs are mainly saved in router’s memory (RAM) or disk. MikroTik logs can also be sent by email or even can be sent to a remote syslog server. All logs those are saved in router’s local memory can be viewed from Log menu. Any log entry that is saved in local memory contains time and date when event occurred, topics that this message belongs to and message itself. But local log information is not enough for analyzing user’s activity completely. So, if you wish to view user activity elaborately, you must use any remote syslog server.
