In this guide we show how to configure a Prometheus instance to securely send metrics to your Opstrace instance.
- An Opstrace instance.
- A decision: for which Opstrace tenant would you like to send data?
- An Opstrace tenant authentication token file (for the tenant of your choice). Also see concepts.
A Prometheus instance can be instructed to replicate its state to a remote system by defining a remote_write configuration block.
What follows is the basic structure of this configuration block to make Prometheus send data to your Opstrace instance:
remote_write:- url: <string>bearer_token_file: <filename>tls_config:insecure_skip_verify: <boolean>
This is the tenant-specific data API endpoint of an Opstrace instance for ingesting metrics. The endpoint URL is constructed using the tenant name and the instance name:
Your Opstrace instance exposes the metrics ingestion API securely. For authenticating the client towards the Opstrace instance, the client has to present a tenant-specific data API authentication token with every request.
To achieve that, we use the
TLS is used for establishing a secure, private transport between the Prometheus instance and the Opstrace instance.
By default, the Prometheus instance attempts to verify the certificate exposed by the Opstrace instance against its trust store, for establishing authenticity of the Opstrace instance towards Prometheus.
Depending on the
cert_issuer instance configuration option (see configuration) you may want to disable server certificate verification for testing purposes.
This can be achieved via
This is required for example when using
