Kubernetes Controller Manager (deprecated)

Use this Splunk Observability Cloud integration for the kube-controller-manager monitor. See benefits, install, configuration, and metrics

Note: This monitor is deprecated in favor of the prometheus-exporter monitor. See Prometheus Exporter for more information.

The monitor queries path /metrics by default when no path is configured. It converts the Prometheus metric types to Splunk Observability Cloud metric types as described in the documentation for Prometheus Exporter. All Prometheus labels are converted directly to Infrastructure Monitoring dimensions.

Configuration settings

The following table shows the configuration options for this monitor:

Option

Required

Type

Description

httpTimeout

no

int64

HTTP timeout duration for both read and writes. This should be a

duration string that is accepted by https://golang.org/pkg/time/#ParseDuration (default: 10s)

username

no

string

Basic Auth username to use on each request, if any.

password

no

string

Basic Auth password to use on each request, if any.

useHTTPS

no

bool

If true, the agent will connect to the server using HTTPS

instead of plain HTTP. (default: false)

httpHeaders

no

map of strings

A map of HTTP header names to values. Comma separated multiple

values for the same message-header is supported.

skipVerify

no

bool

If useHTTPS is true and this option is also true, the

exporter’s TLS cert will not be verified. (default: false)

caCertPath

no

string

Path to the CA cert that has signed the TLS cert, unnecessary if

skipVerify is set to false.

clientCertPath

no

string

Path to the client TLS cert to use for TLS required connections

clientKeyPath

no

string

Path to the client TLS key to use for TLS required connections

host

yes

string

Host of the exporter

port

yes

integer

Port of the exporter

useServiceAccount

no

bool

Use pod service account to authenticate. (default:

false)

metricPath

no

string

Path to the metrics endpoint on the exporter server, usually

/metrics (the default). (default: /metrics)

sendAllMetrics

no

bool

Send all the metrics that come out of the Prometheus exporter

without any filtering. This option has no effect when using the Prometheus exporter monitor directly since there is no built-in filtering, only when embedding it in other monitors. (default: false)

Metrics

These are the metrics available for this integration. All metrics are custom and are only emitted if specified explicitly.

Notes

  • To learn more about the available in Splunk Observability Cloud see Metric types.

  • In host-based subscription plans, default metrics are those metrics included in host-based subscriptions in Splunk Observability Cloud, such as host, container, or bundled metrics. Custom metrics are not provided by default and might be subject to charges. See Metric categories for more information.

  • In MTS-based subscription plans, all metrics are custom.

  • To add additional metrics, see how to configure extraMetrics in Add additional metrics.
