It’s a centralised multi-tenant store, supporting the Prometheus query API. So you can point clients directly at Mimir, they send in PromQL and they get data back in Json.
(Note I work on Mimir)
- eatonphil 5y agoIs there an example of running mimir without prometheus?
- bboreham 5y agoFor example sending metrics from an OpenTelemetry pipeline. Mimir accepts the Prometheus remote-write api, which is protobuf-over-http; can be generated by anything really.
- k8sToGo 5y agoBut who does the scraping of the prometheus agents? Mimir or still prometheus server?
- bboreham 5y agoIf you have systems exporting metrics in Prometheus style, then you can use Prometheus to scrape them and remote-write to Mimir. You can alternately use Prometheus Agent, to save storing the data and running a query engine at the leaf. You can also use the OpenTelemetry suite to perform the same operation, though this is more appealing if you want some other OpenTelemetry features at the same time. Eg if you prefer the ‘pipeline’ style.
- inkel 5y agoYou configure with Remote Write [1] to the Mimir instance. Then the Prometheus agents will send the metrics to Mimir. 1: https://prometheus.io/docs/prometheus/latest/configuration/configuration/#remote_write https://prometheus.io/docs/prometheus/latest/configuration/c...
- Duologic 5y agoLast year I wrote a blog post about this exact question: Who watches the watchers? The general takeaway is that you run a minimal prometheus/alertmanager setup that only scrapes the agents, then use a dead man switch-like system to ensure this pipeline keeps working.
