Swap

Configuration

The swap collector is used to collect the usage of the host swap memory.

Collector Configuration

Go to the conf.d/host directory under the DataKit installation directory, copy swap.conf.sample and name it swap.conf. Examples are as follows:

[[inputs.swap]]
  ##(optional) collect interval, default is 10 seconds
  interval = '10s'
  ##

[inputs.swap.tags]
# some_tag = "some_value"
# more_tag = "some_other_value"

After configuration, restart DataKit.

Can be turned on by ConfigMap Injection Collector Configuration or Config ENV_DATAKIT_INPUTS .

Can also be turned on by environment variables, (needs to be added as the default collector in ENV_DEFAULT_ENABLED_INPUTS):

  • ENV_INPUT_SWAP_INTERVAL

    Collect interval

    Type: TimeDuration

    ConfField: interval

    Default: 10s

  • ENV_INPUT_SWAP_TAGS

    Customize tags. If there is a tag with the same name in the configuration file, it will be overwritten

    Type: Map

    ConfField: tags

    Example: tag1=value1,tag2=value2

Metric

For all of the following data collections, a global tag named host is appended by default (the tag value is the host name of the DataKit), or other tags can be specified in the configuration by [inputs.swap.tags]:

[inputs.swap.tags]
 # some_tag = "some_value"
 # more_tag = "some_other_value"
 # ...
