The “updating client registry” message you’ve described indicates the server is processing messages from the keepalive queue, which are published by each client every 20 seconds.
See https://sensuapp.org/docs/latest/reference/clients.html for more detail on client keepalive behavior.
Aside from “updating client registry” debug messages, which are part of normal operation, are you seeing some other behavior that leads you to believe monitoring is not available?

When we update a check definition and restart the sensu servers we see a lot of “updating client registry” entries in the logs.
The whole process takes about 30 minutes which means we don’t have monitoring available at this time.
Any idea how to speed up this process?
Sensu servers: 6x VMs
Checks: per client ca. 6x (total: 9000x)
Thanks in advanced!
