 I tried ntopng again in December 2023.  I ran in a Docker container on my Router, although markedly improved since trying a few years ago this this program suite still uses uses a lot of resources on my router which loads it up close to 50%.  There are occasional reports of dropped packet and such, further indicating overload.\\  I noted a problem with installing the Docker version.  The Docker package documentation and defaults are to the ''latest'', yet the available package is listed as ''stable'', e.g. ''docker run -it -p 3000:3000 --net=host ntop/ntopng:stable -i br0'' versus the instructed ''docker run -it -p 3000:3000 -v $(pwd)/ntopng.license:/etc/ntopng.license:ro --net=host ntop/ntopng:latest -i br0'' \\ I tried ntopng again in December 2023.  I ran in a Docker container on my Router, although markedly improved since trying a few years ago this this program suite still uses uses a lot of resources on my router which loads it up close to 50%.  There are occasional reports of dropped packet and such, further indicating overload.\\  I noted a problem with installing the Docker version.  The Docker package documentation and defaults are to the ''latest'', yet the available package is listed as ''stable'', e.g. ''docker run -it -p 3000:3000 --net=host ntop/ntopng:stable -i br0'' versus the instructed ''docker run -it -p 3000:3000 -v $(pwd)/ntopng.license:/etc/ntopng.license:ro --net=host ntop/ntopng:latest -i br0'' \\
-Another thing I do not like about this package is that the free community version is a significantly cut down of the full paid version.  The cost on the paid versions are substaincial and I can simply not justify for non-comerical home use.  There is no general individual personal free full use version available.\\ +Another thing I do not like about this package is that the free community version is a significantly cut down of the full paid version.  The cost on the paid versions are substantial and I can simply not justify for non-commercial home use.  There is no general individual personal free full use version available.  The Docker container image is 2GB in size, the biggest image I have seen to date.

 That being said, I can see the benefits of containerisation, such as Docker, versus full virtual machines, such as KVM. Of course there are also benefits with full VMs!. That being said, I can see the benefits of containerisation, such as Docker, versus full virtual machines, such as KVM.

 +In 2022 I revisited Docker and basically have move my various VM applications to Docker containers/ stacks.  I run my Docker instance in a VM to isolate Docker from bare metal.  This is primarily as Docker plays around with iptables. I do not like this, particularly on my main router machine that I use on bare metal nftables as the router/fire software.
