Minimal ingestion profile for control plane Metrics in Managed Prometheus

Azure Monitor metrics addon collects many Prometheus metrics by default. Minimal ingestion profile is a setting that helps reduce ingestion volume of metrics, as only metrics used by default dashboards, default recording rules and default alerts are collected. This section describes how this setting is configured specifically for control plane metrics. This section also lists metrics collected by default when minimal ingestion profile is enabled.

Note

For addon based collection, Minimal ingestion profile setting is enabled by default. The discussion here is focused on control plane metrics. The current set of default targets and metrics is listed here.

Following targets are enabled/ON by default - meaning you don't have to provide any scrape job configuration for scraping these targets, as metrics addon scrapes these targets automatically by default:

• controlplane-apiserver (job=controlplane-apiserver)
• controlplane-etcd (job=controlplane-etcd)

Following targets are available to scrape, but scraping isn't enabled (disabled/OFF) by default. Meaning you don't have to provide any scrape job configuration for scraping these targets, and you need to turn ON/enable scraping for these targets using the ama-metrics-settings-configmap under the default-scrape-settings-enabled section.

• controlplane-cluster-autoscaler
• controlplane-kube-scheduler
• controlplane-kube-controller-manager

Note

The default scrape frequency for all default targets and scrapes is 30 seconds. You can override it for each target using the ama-metrics-settings-configmap under default-targets-scrape-interval-settings section.

Minimal ingestion for default ON targets

The following metrics are allow-listed with minimalingestionprofile=true for default ON targets. The below metrics are collected by default, as these targets are scraped by default.

controlplane-apiserver:

• apiserver_request_total
• apiserver_cache_list_fetched_objects_total
• apiserver_cache_list_returned_objects_total
• apiserver_flowcontrol_demand_seats_average
• apiserver_flowcontrol_current_limit_seats
• apiserver_request_sli_duration_seconds_bucket
• apiserver_request_sli_duration_seconds_sum
• apiserver_request_sli_duration_seconds_count
• process_start_time_seconds
• apiserver_request_duration_seconds_bucket
• apiserver_request_duration_seconds_sum
• apiserver_request_duration_seconds_count
• apiserver_storage_list_fetched_objects_total
• apiserver_storage_list_returned_objects_total
• apiserver_current_inflight_requests

Note

apiserver_request_sli_duration_seconds_bucket and apiserver_request_duration_seconds_bucket are not collected now with a recent release. These are high cardinality metrics which may increase the number of metrics stored based on the number of custom resources in the cluster. If you would like to collect these bucket metrics, you can add it to the keep list. We highly recommend not turning off the minimal ingestion profile for the control plane components

controlplane-etcd:

• etcd_server_has_leader
• rest_client_requests_total
• etcd_mvcc_db_total_size_in_bytes
• etcd_mvcc_db_total_size_in_use_in_bytes
• etcd_server_slow_read_indexes_total
• etcd_server_slow_apply_total
• etcd_network_client_grpc_sent_bytes_total
• etcd_server_heartbeat_send_failures_total

Minimal ingestion for default OFF targets

The following are metrics that are allow-listed with minimalingestionprofile=true for default OFF targets. These metrics aren't collected by default. You can turn ON scraping for these targets using default-scrape-settings-enabled.<target-name>=true using the ama-metrics-settings-configmap under the default-scrape-settings-enabled section.

controlplane-kube-controller-manager:

• workqueue_depth
• rest_client_requests_total
• rest_client_request_duration_seconds

controlplane-kube-scheduler:

• scheduler_pending_pods
• scheduler_unschedulable_pods
• scheduler_queue_incoming_pods_total
• scheduler_schedule_attempts_total
• scheduler_preemption_attempts_total

controlplane-cluster-autoscaler:

• rest_client_requests_total
• cluster_autoscaler_last_activity
• cluster_autoscaler_cluster_safe_to_autoscale
• cluster_autoscaler_failed_scale_ups_total
• cluster_autoscaler_scale_down_in_cooldown
• cluster_autoscaler_scaled_up_nodes_total
• cluster_autoscaler_unneeded_nodes_count
• cluster_autoscaler_unschedulable_pods_count
• cluster_autoscaler_nodes_count
• cloudprovider_azure_api_request_errors
• cloudprovider_azure_api_request_duration_seconds_bucket
• cloudprovider_azure_api_request_duration_seconds_count

Note

The CPU and memory usage metrics for all control-plane targets are not exposed irrespective of the profile.
