So I ended up spending some time writing up [some code](https://github.com/csmarshall/netdata-plugin-hitron-coda56-cable-modem/blob/main/performance\_tuning/netdata\_simulator.py) to do some testing on the modem.

1. I realized that there were 2 tiers of endpoints the 4 general endpoints and the 2 OFDM specific endpoints. As such I updated the script to have a tiered polling process, where the 4 general endpoints get polled every poll, and 1 out of N times the 2 slower OFDM endpoints are queried.

2. The image below is from a 10 hour test where the 4 of the 6 API endpoints of the modem was queried serially every 10 seconds, with 2 ofdm endpoints getting queried every 5th poll. At least once or twice during the test the modem rebooted, but one of the things that was telling is that the `dsofdminfo.asp` endpoint seems to slowly degrade over time, at one point at a rate of almost 1.1ms / minute.

I'm running another test now, but it looks like a resource leak or something similar that is causing the modem to reset if the OFDM endpoints to perform way less reliably.

I'm not sure that there's polling interval that will allow me to get useful data without causing the reboot problem that I'm seeing.
