Whether Management Center persists metrics. Default: true. See Historical Metrics.

Time-to-Live (TTL) in ISO-8601-based durations format for each record in the metrics persistence. Default: P1D (one day). This value must be positive. See Historical Metrics.

Whether Management Center generates a regular healthcheck report. Default: true. See Running a Config Healthcheck.

Whether Management Center sends usage data to the Hazelcast phone home server. Default: true. See Usage Analytics.

Metrics to include in the /metrics endpoint. Default: ' ' (empty).

Metrics to exclude from the /metrics endpoint. Default: ' ' (empty).

Port on which the /metrics endpoint is exposed.

In this example, the /metrics endpoint would be available on port 2222: http://localhost:2222/metrics.

Path to a text file that contains words that cannot be included in user passwords.
