kube Proxy

By tracking the runtime metrics of kube-proxy, it helps to understand information such as the load of the network proxy, response time, synchronization status, etc.

Configuration¶

Prerequisites¶

Datakit has been installed

Configure Datakit¶

Go to the conf.d/samples directory under the datakit installation directory, copy prom.conf.sample and rename it to kube-proxy.conf

cp prom.conf.sample kube-proxy.conf

Adjust the content of kube-proxy.conf as follows:

[[inputs.prom]]
  ## Exporter URLs.
  urls = ["http://127.0.0.1:10249/metrics"]

  uds_path = ""

  ignore_req_err = false

  source = "kube-proxy"

  measurement_prefix = ""

  keep_exist_metric_name = false


  election = true

  disable_host_tag = false

  disable_instance_tag = false

  disable_info_tag = false


  [[inputs.prom.measurements]]
    prefix = "etcd_network_"
    name = "etcd_network"

  [[inputs.prom.measurements]]
    prefix = "etcd_server_"
    name = "etcd_server"

  [inputs.prom.tags_rename]
    overwrite_exist_tags = false

  [inputs.prom.as_logging]
    enable = false
    service = "service_name"

Restart datakit Execute the following command

datakit service -R

Metrics¶

kube-proxy Metrics Set¶

The Kube Proxy metrics are located under the kubeproxy metrics set. Here we introduce relevant explanations for Kube Proxy metrics.

Metrics	Description	Unit
`network_programming_duration_seconds_bucket`	`Time distribution of network programming operations`	s
`network_programming_duration_seconds_count`	`Total number of network programming operations that occurred`	count
`network_programming_duration_seconds_sum`	`Total time spent on all network programming operations`	s
`sync_proxy_rules_duration_seconds_bucket`	`Time distribution of sync proxy rules operations`	s
`sync_proxy_rules_duration_seconds_count`	`Total number of sync proxy rules operations`	count
`sync_proxy_rules_duration_seconds_sum`	`Total time spent on all sync proxy rules operations`	count
`sync_proxy_rules_endpoint_changes_pending`	`Number of endpoint changes waiting to be synchronized`	count
`sync_proxy_rules_endpoint_changes_total`	`Total number of times endpoints have been synchronized`	count
`sync_proxy_rules_iptables_restore_failures_total`	`Number of times IPTables rule restoration failed`	count
`sync_proxy_rules_no_local_endpoints_total`	`Number of services with no local endpoints`	count
`sync_proxy_rules_service_changes_pending`	`Number of service configuration changes waiting to be synchronized`	count
