Description

Configured NameNode HA. Build #435, 3-node cluster

The Percent JournalNodes Available alert has no instances. But the JournalNode process alert has three instances as expected.

This happens when the alert has not run yet and the component is brought online. The first time the alert runs, it records an OK, which is technically not a state change (since there was no prior state). Because no state change occurred, the aggregate listener did not fire.
