InfluxDB is a purpose-built time-series database — a fast, well-loved place to store metrics and query them with Flux or InfluxQL. It does that one job well. What it doesn't do is the rest of operating a fleet: you still build ingestion pipelines, dashboards, alert rules, and notification plumbing. Plexus is that whole layer, finished — it includes the time-series store (3-year raw retention, 5-year hourly rollups) and adds auto-generated dashboards, threshold/event/offline monitors with routing, and a per-alert audit trail, so you don't stand up a TSDB and hand-build operations around it.
InfluxDB is a time-series database. InfluxDB is a time-series database you'd build a fleet UI on; Plexus includes time-series storage and ships the dashboards, monitors, and alert history already built on top. This page is written by Plexus, so read it with that in mind — we’ve tried to be straight about where InfluxDB is the better choice. Last updated July 2026.
Already storing telemetry in Postgres, TimescaleDB, MySQL, or ClickHouse? Plexus connects to those directly — no migration. InfluxDB itself isn't a supported connection today, so an Influx-centric stack is a genuine either/or: keep Influx and build your own frontend, or let Plexus be both the store and the frontend.

| Capability | Plexus | InfluxDB |
|---|---|---|
Purpose-built TSDB query language (Flux / InfluxQL) If you want a general-purpose TSDB to query directly, that's Influx's strength. | ○ | ● |
Standalone time-series store you run and build on Influx is a database to operate and build on; Plexus is a platform that happens to include storage. | ◐ | ● |
Direct, arbitrary querying of raw metrics Influx gives you full query access; Plexus queries through its dashboards, API, and terminal, shaped around operations. | ◐ | ● |
Time-series storage included Plexus includes a store with 3-year raw retention and 5-year hourly rollups; with Influx you run the database. | ● | ● |
Dashboards auto-generated from first ingest Influx has basic visualization; Plexus builds the fleet dashboard from the data that actually lands. | ● | ○ |
Threshold, event, and offline monitors with routing Influx has tasks and basic alerting; Plexus ships monitors with per-monitor email, Slack, or webhook routing and offline detection for sources that go dark. | ● | ◐ |
Per-alert audit trail with verdict capture Alert lifecycle, timeline, and verdicts are frontend concerns a TSDB doesn't carry. | ● | ○ |
Connects to an existing datastore in place Plexus reads Postgres, TimescaleDB, MySQL, and ClickHouse in place. InfluxDB itself isn't a supported connection today. | ● | ○ |
Pick InfluxDB Pick InfluxDB as a standalone time-series database if you want a purpose-built store with its own query language to build your own systems and dashboards on.
Pick Plexus Pick Plexus if you want the whole operating layer out of the box — storage, auto-generated dashboards, monitors with routing, and alert history as one platform — instead of running a TSDB and building the frontend on top of it yourself.
For a fleet's telemetry backend plus its operations UI, yes. Plexus includes time-series storage and ships dashboards, monitors, and alert history already built, so you don't run a separate TSDB and assemble the rest. If what you want is a general-purpose time-series database to query and build on directly, that's InfluxDB's job, not Plexus's.
Plexus includes storage — 3-year raw retention (7 days hot, then S3) and 5-year hourly rollups — so you don't need a separate TSDB. If your data already lives in Postgres, TimescaleDB, MySQL, or ClickHouse, Plexus connects to those in place. InfluxDB itself isn't a supported connection today.
Everything above the raw store: SDK and HTTP ingestion, dashboards that generate themselves from the first data, threshold/event/offline monitors with per-monitor notification routing, a full alert timeline with verdicts, and a plain-language ⌘K terminal — without building or operating any of it.
