kube Proxy

By tracking the performance metrics of kube proxy, it helps to understand the load, response time, synchronization status, and other information of network agents

Config¶

Preconditions¶

Installed datakit

Configure Datakit¶

Go to the conf.d/prom directory under the datakit installation directory, copy prom.conf.sample and name it 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

Metric¶

kube-proxy Metric set¶

The Kube Proxy metric is located under the kubeproxy metric set. Here is an introduction to the Kube Proxy metric

`sync_proxy_rules_duration_seconds_bucket`	`Time distribution of synchronous proxy rule operations`	s
`sync_proxy_rules_duration_seconds_count`	`The total number of synchronous proxy rule operations`	count
`sync_proxy_rules_duration_seconds_sum`	`The total time required for all synchronous proxy rule operations`	count
`sync_proxy_rules_endpoint_changes_pending`	`How many endpoint changes are waiting to be synchronized`	count
`sync_proxy_rules_endpoint_changes_total`	`The total number of synchronized endpoint changes`	count
`sync_proxy_rules_iptables_restore_failures_total`	`The number of times IPTables rule recovery failed`	count
`sync_proxy_rules_no_local_endpoints_total`	`Number of services without local endpoints`	count
`sync_proxy_rules_service_changes_pending`	`How many service configuration changes are waiting to be synchronized`	count
