A few words about jail traffic counting

command: fwcounters

Description:

Currently, the easiest way to count traffic - use functional of ipfw count on the JID of necessary environment.

Necessary conditions for the implementation of this:

  • loaded module ipfw.ko;
  • mounted in CBSD (for example via cbsd initenv-tui) ipfw_enable parameters to 1;
  • count the presence of the rules in ipfw before any other firewall rules.

CBSD starting and stopping the jails and removes automatically sets the rules for traffic jail, using a range of these rules settingCBSD (range by default fwcount_st="99" - fwcount_end="2000" )

In other words, if you want to count traffic and still have the ability to filter traffic, create filtering rules above 2000 and not taking rules from 99 to 2000.

Collect of traffic occurs 1 time per hour or when stopping the jail and stored in SQLite3 base, located in the system directory jail: $workdir/jails-system/$jname/traffic/YYYY-MM.sqlite, where YYYY, MM - year and month.

Example. Enjoying the traffic statistics for the jail kde4. meaning of the fields outgoing and incoming - in bytes:

root@home:/ # sqlite3 /usr/jails/jails-system/kde4/traffic/2014-09.sqlite 
SQLite version 3.8.6 2014-08-15 11:46:33
Enter ".help" for usage hints.

sqlite> .schema traffic
CREATE TABLE traffic (  dt TIMESTAMP DATE DEFAULT (datetime('now','localtime')) UNIQUE PRIMARY KEY, incoming integer, outgoing integer  );

sqlite> select * from traffic order by dt desc limit 15;
