Prometheus

Prometheus is an open-source systems monitoring and alerting toolkit designed for reliability and scalability in cloud-native and containerized environments. It provides powerful time-series data collection, storage, and querying capabilities for infrastructure and application monitoring, performance tracking, and observability.

Before you start

Prometheus needs no credentials — Huntbase queries it without signing in.

Connect Prometheus

1. Go to Connections and click New connection, or click New connection on the Prometheus product page.
2. On Product, pick Prometheus and choose the Owner.
3. On Details, give the connection a Name and, optionally, a Description.
4. On Connect, fill in the settings and credentials described below.
5. On Verify, review the summary and click Create & check.

For everything else on the setup page — saving a draft, I'll do this later, and what each check result means — see Connections.

Settings

Where your Prometheus lives:

Field	Required	Notes
Prometheus Address	No	The HTTP address of your Prometheus server, such as http://localhost:9090.
Metrics	No	Regular expressions for the metric names to expose as tables, such as prometheus_http_requests_.*.

Credentials

The only Method is No Authentication. Enter a Credential label (for example Production), then fill in:

No fields — choose this method to connect without credentials.

Query it

Once connected, Prometheus can serve these languages in a query tab, and Scout can use it when you ask in Auto:

Language	Use it for
SQLite	SQL over the 7 tables listed below, alongside every other connected source.

Example: SQLite

List all alerts — Gain insights into all the alerts currently active in your system.

select
  *
from
  prometheus_alert;

Prometheus ships with 25 query templates. Find them in Library › Queries — see Query templates.

Tables

Prometheus adds 7 tables. Browse their columns from Schema in the query bar's ⋯ menu.

All 7 tables

Table	Contains
prometheus_alert	Alerts currently firing on the Prometheus server.
prometheus_label	Labels used in metrics in the Prometheus server.
prometheus_metric	Query metrics in the Prometheus server.
prometheus_rule	Rules in the Prometheus server.
prometheus_rule_group	Rule groups in the Prometheus server.
prometheus_series	Series in the Prometheus server.
prometheus_target	Target scraped by the Prometheus server.
