TCP 8086
Synopsis
- InfluxDB uses TCP port 8086 by default for its HTTP API in both v1.x and v2.x.
- Real examples: Telegraf agents send metrics to http://host:8086, Grafana and Chronograf query InfluxDB on 8086, and Home Assistant/openHAB InfluxDB add-ons connect to InfluxDB on this port.
- Google Cloud Bigtable Emulator (from the Google Cloud SDK) listens on 8086 by default for client connections during local development (e.g., BIGTABLE_EMULATOR_HOST=localhost:8086).
- Security note: Exposed InfluxDB services on 8086 without authentication have been targeted to read or write data and have been abused in opportunistic attacks (e.g., dropping cryptominers or exfiltrating metrics).
