Entropy and netdev problems

Hey guys,

My Ubuntu server is running Netdata and it keeps throwing alerts about Netdev and periodically Entropy. I have followed the Red Hat guide as best I can but I cant seem to get netdev to calm down.

Here is my sysctl.conf file: https://pastebin.com/Kf29QuQq

Here are some screenshots of my netdata to show what it looks like right now.

Don’t know if you found a solution to this over the last 4 months, but I was trying out the new question mark feature and found your post.

Regarding entropy. I chose to use a random number generator called haveged, on my ubuntu server. Try and see if you server’s entropy lever is below 1000 with this command. If it is, you should probably do something about it.

cat /proc/sys/kernel/random/entropy_avail

As stated in this guide on the Arch wiki

As I mentioned, I use haveged, a minimal resource program. I don’t know if there are alternatives out there, or if there are specific security concerns regarding your use case. In any case, haveged can be installed from the default ubuntu repository.

sudo apt install haveged
