Query Explanation

The rule watches the cassandra_stats{name="org:apache:cassandra:metrics:storage:totalhints:count"} metric and uses changes(...[1m]) to count how many times the hint count value changes in the past minute; if it changes more than three times (> 3), the alert fires, signalling rapid hint‑count fluctuations that may indicate nodes are going down.
