Which is better for mixed cloud-native and legacy environments: HertzBeat or Zabbix?

Neither tool is a strict upgrade over the other; the right pick depends on what the environment actually needs.

HertzBeat's case: agentless YML templates onboard cloud-native and modern services fast, cloud-edge collectors handle isolated network segments cleanly, and the all-in-one design (collection + storage + alerting + notification) means fewer separate tools to run. It's a good fit when a team wants speed of setup and a smaller operational footprint.

Zabbix's case: it's a much longer-established project with deep, battle-tested support for very large legacy fleets, a mature agent that captures low-level OS metrics HertzBeat would need SSH command execution to approximate, and a larger base of enterprise deployment experience to draw on.

A reasonable rule of thumb: HertzBeat tends to be the stronger fit for cloud-native-heavy environments prioritizing fast onboarding and a unified platform, while Zabbix still has an edge for very large, long-running legacy estates where deep agent-based OS visibility and a long enterprise track record matter more than setup speed. Many teams also run both during a transition period rather than treating it as all-or-nothing.
