Operations Enterprise

caution

This feature is in alpha and certain aspects will change

We're very excited for people to use this feature. However, please note that changes in the API, behaviour and security will evolve. The feature is suitable to use in controlled testing environments.

As platform engineer you could need to have a finer understanding on the underlying logic for Explorer. The following options are available to you to operate and troubleshoot it.

Debug Access Rules​

It is a debugging tool to make visible explorer authorization logic. You could find it as tab Access Rules alongside the Query tab.

access rules

You could discover by Cluster and Subject the Kinds it is allowed to read. These are the rules that will be the source of truth doing authorization when a user does a query.

Monitoring​

Explorer provides the following telemetry to use for operations.

Metrics​

Explorer exports Prometheus metrics.

Configuration happens during releasing as shown below.

apiVersion: helm.toolkit.fluxcd.io/v2beta1

    #### Metrics - Prometheus metrics configuration
    metrics:
      # Enables metrics generation and prometheus endpoint
      enabled: false
      service:
        # -- Port to start the metrics exporter on
        port: 8080
        # -- Annotations to set on the service

          prometheus.io/path: "/metrics"
          prometheus.io/port: "{{ .Values.metrics.service.port }}"

Querying​

Based on go-http-metrics, the following metrics are generated.

Request Duration: histogram with the latency of the HTTP requests.

http_request_duration_seconds_bucket{handler="/v1/query",method="POST",le="0.05"} 0
http_request_duration_seconds_sum{handler="/v1/query",method="POST"} 10.088081923
http_request_duration_seconds_count{handler="/v1/query",method="POST"} 51

Response Size: histogram with the size of the HTTP responses in bytes

http_response_size_bytes_bucket{handler="/v1/query",method="POST",le="0.05"} 10
http_response_size_bytes_sum{handler="/v1/query",method="POST"} 120
http_response_size_bytes_count{handler="/v1/query",method="POST"} 10

Request In Flight: gauge with the number of inflight requests being handled at the same time.

http_requests_inflight{handler="/v1/query"} 0
