Common questions
Is there any cost to use either tool?
Both Glances and zap are free and open‑source.
Can I use zap on Windows servers?
Zap runs wherever Go runs, so it works on Windows, but it only logs Go applications, not system metrics.
Does Glances provide alerting out of the box?
Glances includes configurable alert thresholds, but alerts require manual setup or external scripts.
