Sensu HA cluster unstability

Sensu Go
#1

I have 3 node Sensu Go HA cluster running docker service.
Cluster is running but its very unstable. Frequently the cluster goes down with lot of etcd error.

“error”:“internal error: etcdserver: request timed out”

Would be great to know if anyone got a stable cluster.

Hey!
etcd can be very sensitive to disk latencies… so you might need to change your provisioning to increase CPU or IOPS

We have a section in our troubleshooting documents that covers etcd tuning that might help:

Any additional details you can share here or in that GitHub issue (perhaps following the guide @jspaleta mentioned above) would be greatly appreciated.
