How it works Blackbox-exporter

Introduction

Blackbox-exporter is used to monitor applications and different monitoring components (commonly named monitoring of monitoring).

Blackbox-exporter executes probes against endpoints and returns metrics based on the results of those probes.

Probes location (tests source)

NGOT

On NGOT, the probes are deployed on the following service zones svc-monitoring-stack-corp-<production_line>-1 environment (monitoring-stack-corp-obs-corp-<production_line> namespace).

Where production_line can be either prd or stg.

Endpoints (tests destination)

NGOT

For example, for a customer that has both monitoring and logging service, the following endpoints are tested:

• Grafana URL (blackbox-exporter-grafana-obs-$CLIENT probe): http://grafana.obs-$CLIENT.cloudservicesfactory.com/loki/api/v1/push/;
• Loki URL (blackbox-exporter-loki-client-write-obs-$CLIENT probe): http://loki-write.obs-$CLIENT.cloudservicesfactory.com/loki/api/v1/push/;
• Prometheus Remote Write URL (remote-write-{0,1}-obs-$CLIENT-metrics-<production_line> probe).

Blackbox-exporter is also installed in client monitoring service zone (svc-monitoring-stack-client-$CLIENT in monitoring-stack-client-obs-$CLIENT namespace) in order to test the endpoints defined in probes by the customer and deployed with Gitops Workflow.
