Overview
Most observability vendors are SaaS, so Antimetal reaches them directly over their public API. Tools you host yourself are different: they usually live inside your own network or VPC and are not reachable from the public internet. For these, Antimetal runs a dedicated, read-only connector for your organization. You provide the instance URL and a read-only token, and the connector queries that instance on your behalf. This page covers what the connectors need and how to make a private instance reachable. It applies to:- Grafana (self-hosted)
- Victoria Logs
- Victoria Metrics
- Prometheus and Pyroscope, when accessed as Grafana data sources
If you use a managed version of any of these (for example Grafana Cloud), follow the Grafana guide instead. Managed instances are reached over their public endpoint and need no reachability setup.
What the connector needs
Every self-hosted connector requires two things:| Requirement | Detail |
|---|---|
| Instance URL | The HTTPS endpoint of your instance, reachable from the Antimetal connector. |
| Read-only token | A bearer token or service account scoped to read only. Antimetal performs no writes. |
Making a private instance reachable
If your instance is not exposed to the public internet, choose one of the following. You can start narrow and expand later.Option 1: Public endpoint with an IP allowlist
Option 1: Public endpoint with an IP allowlist
Expose the instance over HTTPS, require the read-only token on every request, and restrict inbound access to Antimetal’s egress IP. Traffic is encrypted in transit and authenticated, and only Antimetal’s address can reach the endpoint.
Allowlist Antimetal’s egress IP:
44.195.180.21/32. This is a single static address, so it is safe to pin in your firewall rules.Option 2: Private connectivity
Option 2: Private connectivity
