Hi, As already suggested by James, using a single instance is recommended to monitor multiple interfaces on the same box. ntopng is also multi-tenant so you have the option to create users and associate interfaces and networks to them. In this way you can create non-privileged users that don't have access to all the traffic.
However, if you still want to run multiple instances on the same box, you must use for each instance a different: - redis database id - data dir - http port - pid file or things will be messed up... simone On Fri, Aug 26, 2016 at 11:54 PM, James Lay <j...@slave-tothe-box.net> wrote: > On 2016-08-26 15:39, n...@funkpickle.com wrote: > >> v.2.4.160818 [Professional Edition] >> GIT rev: 2.4-stable:d786da67470dd879c5bbe13d38a7f95f2b598626:20160818 >> Pro rev: r641 >> System Id: 3BB0D75C7A06AB13 >> Built on: Ubuntu 14.04.5 LTS >> >> I am spawning 3 different ntopng instances to monitor different >> network segments on different ethernet adapters.
