Class LicenseUsageGauge

java.lang.Object

io.confluent.license.usage.LicenseUsageGauge

public final class LicenseUsageGauge
extends Object

Registers a per-node license-usage gauge (constant 1.0, tagged with component identity and license fingerprint) on the component's Metrics so its TelemetryReporter exports it. Best-effort: failures are logged and swallowed.

Method Details

refresh

public void refresh(License selectedLicense)

Re-registers the gauge on license change. A null license switches to invalid mode (identity tags plus license_category="invalid"); unchanged fingerprint or already-invalid mode is a no-op.

close

public void close()

Removes the registered gauge, if any. Safe to call multiple times.
