File does not exist

Note that, on the first attempt to upgrade OpenWrt, resulted in a large number of errors from Netdata.

I subsequently removed Netdata, re applied the upgrade firmware, and reinstalled Netdata.

In the Netdata GUI it reports as this version

I have fixed the symptoms, but I am not sure it should have been an issue in the first place.

Ref Issue https://github.com/openwrt/packages/issues/8968

TL;DR The solution is to disable the ipc plugin.

To help others:

Netdata works on default settings overwritten by settings in /etc/netdata/netdata.conf You can see the settings in use by navigating to http://IP_where_netdata_is_running:19999/netdata.conf.

SSH into the router and edit the /etc/netdata/netdata.conf file and add the following lines

[plugin:proc]
        ipc = no

You can add in the nano editor from the System -> Software menu on LuCI.

Reboot, and the log messages are gone.

HTH
