Tools / Apache HertzBeat Interview Questions

When would you choose VictoriaMetrics vs IoTDB for HertzBeat?

Both are supported HertzBeat storage backends, but they fit different situations.

VictoriaMetrics	Apache IoTDB
HertzBeat's own documented default recommendation.	Strong fit if you already run IoT/industrial time-series workloads.
PromQL-compatible, simple operationally.	Purpose-built for very high-cardinality IoT sensor data.
Good general-purpose choice for most teams.	Useful when consolidating with an existing IoTDB deployment.

For a typical infrastructure/application monitoring deployment with no other IoTDB usage, VictoriaMetrics is the simpler default; IoTDB makes more sense when a team already standardizes on it elsewhere.

HertzBeat's documentation recommends which TSDB by default? VictoriaMetrics

✓ Correct! Well done.

Apache IoTDB

✗ Try again if not.

Neither; a TSDB is mandatory to even start HertzBeat

✗ Try again if not.

Choosing IoTDB makes the most sense when: You have no existing time-series infrastructure at all

✗ Try again if not.

Your team already standardizes on IoTDB elsewhere

✓ Correct! Well done.

You need agentless collection specifically

✗ Try again if not.
