GUI - Dashboard, Logging, Report
NxFilter can keep its log data up to 400 days and generates a daily, weekly and a user level report based on the log data.

On the dashboard of NxFilter, There are several charts for showing the activity in your network for the last 2 hours. At the bottom of the dashboard, you can see up to 10 recent block logs for the last 12 hours.

The difference between 'request-sum' and 'request-cnt' is from NxFilter's logging system. To reduce the amount of disk access, NxFilter keeps all the log data into its memory space before it flushes out the data once in a minute. If there is a request for the same domain from the same user in a minute, it only increases the count for the data. So, 'request-sum' means the sum of all the requests and 'request-cnt' means the count for all the unique data.

Logging > Request
You can search through DNS request log data with various conditions on 'Logging > Request'. Logging data is being updated once in a minute to reduce the load of your system.

Use square brackets for the exact matching keyword on log search.
    ex) [nxfilter], []
