Here is our setup :
Packbeat(v0.5) * 8 >> Redis (v3.0.5) << Logstash(v1.5.5) >> elasticsearch(v1.7.3)
We are very satisfy with this setup except we notice a memory leak on our redis server. Memory usage increases gradually every time, and finishes to reach the memory limit. When it's happening, we don't have any other choice to restart the redis server and all packetbeat agents.
Here is some graphs which show the activity on 6 hours.
Anybody encounter this issue ?
