I've recently installed netdata on an Amazon EC2 debian instance that I have. Netdata is pretty cool, nice charts/graphs, painlessly easy to install (compared to others.)
A number of times each day I receive a message such as
1m ipv4 udp receive buffer errors = 9 errors number of UDP receive buffer errors during the last minute
and a few minutes later, a recovery message. There are probably hundreds of errors indicated with UDP/TCP through out the day. I also see a similar pattern on a server I have runnning at home.
I've used other monitoring packages over the years and have never seen errors of this type. I suspect some level of errors, especially on UDP, are normal, is that right? Is this expected behavior? Can I turn off the monitoring of these alarms?
I've moved to a second NIC on the machine at home with no essential change in behavior.
This Acceptable number of ethernet errors in a medium sized environment? suggests that I might have a serious problem, and I can certainly try other NICs at home. But however would I solve this on my EC2 instance?
It may also be worth noting that logwatch reports no problems at all, but then, it may not be configured for this.
Thanks for guidance.
