What DumbMonit watches
The time series database and the log database themselves: whether they accept what they are sent, how much disk is left before they stop accepting anything, and what they refuse.
Typical use. Time series database: ingestion, refused samples, disk headroom

Setup steps: Let DumbMonit read VictoriaMetrics' own health
Nothing to install: check from the DumbMonit host that VictoriaMetrics answers on its API port (8428 by default).
curl http://victoriametrics.lan:8428/healthIf it runs with -httpAuth.username and -httpAuth.password, pick Username / password below; behind vmauth or a proxy that expects a bearer token, pick Bearer token.
In DumbMonit, enter the server address, for example "victoriametrics.lan" or "http://10.0.0.5:8428".
Heads-up. Free disk space is what to watch: below -storage.minFreeDiskSpaceBytes (100 MB by default) VictoriaMetrics turns read-only and refuses every new sample. DumbMonit shows the headroom left and warns under 10%.
