Where does the mongodb's web ui populate its logs from?

[Rmon]

Where does the mongodb's web ui collect the logs from? are the log entries written to the database and or are they queried from the journal? 

Example:

Log 

Fri Oct  5 15:15:38 [conn142] end connection 127.0.0.1:57265 (3 connections now open)
           15:15:38 [conn143] end connection 127.0.0.1:57266 (2 connections now open)
           15:15:51 [initandlisten] connection accepted from 127.0.0.1:57270 #144 (3 connections now open)
           15:15:51 [conn144] queryModified: { _id: ObjectId('505e89a26627feb34a000001') }
           15:15:51 [initandlisten] connection accepted from 127.0.0.1:57271 #145 (4 connections now open)
           15:15:51 [conn144] queryModified: { _id: ObjectId('5064eddccc12c5fd57bac60d') }
           15:15:51 [conn144] queryModified: { _id: ObjectId('506515900d9d5f329a2c3c8d') }
           15:15:51 [conn144] queryModified: { _id: ObjectId('506515920d9d5f329a2c3c8e') }

Which 'web UI' are you talking about?  Are you talking about 'MMS'?

If so, the MMS agent will use the 'getLog' command to fetch the log file from every node in the cluster.

The log files are stored in the file system.
