I've been testing out packetbeat as a hobby and I have a couple issues.
First, one where packetbeat won't start:
Fail to set the IP addresses: ERR command not allowed when used memory > 'maxmemory'
/usr/bin/packetbeat: main.go:146: ERR command not allowed when used memory > 'maxmemory'
Also, I had an issue that unfortunately I don't have the logs for now but basically packetbeat was producing a ton of max connections error in syslog (reading proc filesystem).
Any ideas on how to tune packetbeat?
