Introduction
|
|
------------
|
|
You can instruct ntopng to save in MySQL flow information so that you can
|
|
1. Visualize historical information using ntopng
|
|
2. Create your own reports using data stored in MySQL
|
|
|
|
|
|
How To Enable It
|
|
----------------
|
|
In order to enable this feature you need to start ntopng with the -F.
|
|
Example: ntopng -F "mysql;localhost;ntopng;flows;root;"
|
|
|
|
Note that ntopng will create the table automatically (you need to create the DB)
|
|
so no action is required from your side.
|
|
|
|
|
|
Using It
|
|
--------
|
|
Doing that ntopng will dump flow information in MySQL and allow you
|
|
to visualize top flows in the historical view of local hosts (you need
|
|
to click on the graph icon inside the host view). Example
|
|
http://localhost:3000/lua/host_details.lua?ifname=0&host=192.168.1.92&page=historical
|
|
|
|
The ntopng pro version contains much more detailed historical information
|
|
as well it allows you to navigate such information, thing that is not
|
|
possible with the community edition.
|
|
|
|
|
|
Data Retention
|
|
--------------
|
|
In order to avoid filling up your MySQL, ntopng will harvest old data. You
|
|
can specify the retention period in the preferences menu. The default
|
|
retention is 30 days (i.e. data older than 30 days is deleted).
|
|
|
|
|
|
Future Work
|
|
-----------
|
|
In the future we plan to consider adding ElasticSearch support to historical
|
|
view too. |
