Разработчики Netams4 категорически не советуют  использовать источник данных "JPcapLocalDataSource". Поэтому мы добавим источник данных "RemoteAgentDatasource".


* чистка базы
<code bash>
mysql -uroot -p
use netams4;
delete from `utilization` where `period` < '2019-11-01';
OPTIMIZE TABLE utilization;
delete from `monitor` where `ts` < '2019-11-01';
OPTIMIZE TABLE monitor;
