Issue with iptmon installation OpenWRT 21.02.0

[ChrisGoggin]

Thanks for the iptmon plugin I have been using it for quite a while on OpenWrt 19.07.x and it does exactly what I need!

iptmon v0.1.6 installs as per your readme with no problems with OpenWrt 19.07. However, it does not install correctly on 21.02.00.

Luckily I read through the other open issues and found the workaround for my problem in open issue init without static hosts #14

As Juergen noted in his comments if you:

1. manually add dhcpscript to /etc/config/dhcp, as below

config dnsmasq
          option dhcpscript '/usr/sbin/iptmon'

2. add "iptmon init" to /etc/rc.local

Once I made these two changes iptmon is working fine with OpenWrt 21.02.0.

I have raised this issue so that anyone else with similar problems will find a solution quickly.

Thanks again for the great plugin,
Chris

Thanks for opening this. I've been meaning to test against 21.xx builds but haven't gotten around to it. I'm glad you found a workaround.

I will have a closer look soon at implementing official support for OpenWrt 21.xx.

With two different routers on 21.02.1, I implemented the above changes. One seems fine, but the other does this:

Which is interesting, since iptmon, as far as I can tell, is configured the same way. It's unclear what's happening at midnight, but collectd is still running, and the router is not rebooting (though when I do, it will start working again but then just recur). Most of the data in the table below the graph stays the same throughout the day after the midnight event, but a few actually decrease, which is weird since I thought this was cumulative.

In any case, not sure if this is related to 21.02.1 or not.
