Phoning Home
Hazelcast uses phone home data to learn about usage of Hazelcast.
Hazelcast member instances call our phone home server initially when they are started and then for every 24 hours. This applies to all the instances joined to the cluster.

- Hazelcast version

- A hash value of the cluster ID
- Cluster size bands for 5, 10, 20, 40, 60, 100, 150, 300, 600 and > 600
- Number of connected clients bands of 5, 10, 20, 40, 60, 100, 150, 300, 600 and > 600
