Rebooted a couple of days ago. Post RS Errors increasing a lot.

SNR/RxMER all 38+, speedtest giving expected speeds, only a small number of Pre RS errors and no Post RS ones.
Only fly in the ointment is that I ran a speedtest just prior to performing your suggested actions and also got the expected speed. As per the title, this is intermittent 😞
OK, afternoon chore is to automate this data gathering.

The one good thing about this is that I've looked into monitoring the status of the CM. Thanks to other pages on this board I know that
http://192.168.0.1/walk?oids=1.3.6.1.2.1.10.127.1.1.4.1.4
gives the Post RS Errors in JSON format:
{ "1.3.6.1.2.1.10.127.1.1.4.1.4.3":"59", "1.3.6.1.2.1.10.127.1.1.4.1.4.48":"0", "1.3.6.1.2.1.10.127.1.1.4.1.4.49":"0", "1.3.6.1.2.1.10.127.1.1.4.1.4.50":"2", "1.3.6.1.2.1.10.127.1.1.4.1.4.51":"14", "1.3.6.1.2.1.10.127.1.1.4.1.4.52":"0", "1.3.6.1.2.1.10.127.1.1.4.1.4.53":"0", "1.3.6.1.2.1.10.127.1.1.4.1.4.54":"0", "1.3.6.1.2.1.10.127.1.1.4.1.4.55":"26", "1.3.6.1.2.1.10.127.1.1.4.1.4.56":"1", "1.3.6.1.2.1.10.127.1.1.4.1.4.57":"47", "1.3.6.1.2.1.10.127.1.1.4.1.4.58":"45", "1.3.6.1.2.1.10.127.1.1.4.1.4.59":"121", "1.3.6.1.2.1.10.127.1.1.4.1.4.60":"48", "1.3.6.1.2.1.10.127.1.1.4.1.4.61":"75", "1.3.6.1.2.1.10.127.1.1.4.1.4.62":"25", "1.3.6.1.2.1.10.127.1.1.4.1.4.63":"22", "1.3.6.1.2.1.10.127.1.1.4.1.4.64":"28", "1.3.6.1.2.1.10.127.1.1.4.1.4.65":"0", "1.3.6.1.2.1.10.127.1.1.4.1.4.66":"0", "1.3.6.1.2.1.10.127.1.1.4.1.4.67":"0", "1.3.6.1.2.1.10.127.1.1.4.1.4.68":"0", "1.3.6.1.2.1.10.127.1.1.4.1.4.69":"0", "1.3.6.1.2.1.10.127.1.1.4.1.4.70":"0", "1":"Finish" }
at the minute. http://192.168.0.1/walk?oids=1.3.6.1.2.1.10.127.1.1.4.1.5 appears to be the SNR:
{ "1.3.6.1.2.1.10.127.1.1.4.1.5.3":"386", "1.3.6.1.2.1.10.127.1.1.4.1.5.48":"386", "1.3.6.1.2.1.10.127.1.1.4.1.5.49":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.50":"386", "1.3.6.1.2.1.10.127.1.1.4.1.5.51":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.52":"386", "1.3.6.1.2.1.10.127.1.1.4.1.5.53":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.54":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.55":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.56":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.57":"386", "1.3.6.1.2.1.10.127.1.1.4.1.5.58":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.59":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.60":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.61":"386", "1.3.6.1.2.1.10.127.1.1.4.1.5.62":"386", "1.3.6.1.2.1.10.127.1.1.4.1.5.63":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.64":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.65":"386", "1.3.6.1.2.1.10.127.1.1.4.1.5.66":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.67":"389", "1.3.6.1.2.1.10.127.1.1.4.1.5.68":"386", "1.3.6.1.2.1.10.127.1.1.4.1.5.69":"386", "1.3.6.1.2.1.10.127.1.1.4.1.5.70":"386", "1":"Finish" }
which is still looking good.
Running the following hacky line is good enough at the moment:
echo -n $(date -u +%Y-%m-%d,%T,) >> error_count.csv; wget -q -O - http://192.168.0.1/walk?oids=1.3.6.1.2.1.10.127.1.1.4.1.4 | grep "1.3.6.1.2.1.10.127.1.1.4.1.4"| sed 's/1.3.6.1.2.1.10.127.1.1.4.1.4.//;s/:/,/'| sort | xargs >> error_count.csv
The only thing I don't understand is why this reboot worked (with the 5min+ gap) and the one I did previously (with only a few seconds between turning off and on) didn't.
Anyway all fine so far 🙂

Still fine so I'm happy to call that fixed.
Lots of stuff on GitHub to do various things with the Hub3. Didn't realise the SNMP stuff was exposed by the web interface. In case it helps others, the device-specific MIBs are here:
https://mibs.observium.org/mib/ARRIS-CM-DEVICE-MIB/
https://mibs.observium.org/mib/ARRIS-ROUTER-DEVICE-MIB/
Values can be set through that interface too, but that seems a little too dodgy for this forum 🙂
