Windows Performance Counters Receiver

This receiver, for Windows only, captures the configured system, application, or custom performance counter data from the Windows registry using the PDH interface. It is based on the Telegraf Windows Performance Counters Input Plugin.

• Memory\Committed Bytes
• Processor\% Processor Time, with a datapoint for each Instance label = (_Total, 1, 2, 3, ... )

If one of the specified performance counters cannot be loaded on startup, a warning will be printed, but the application will not fail fast. It is expected that some performance counters may not exist on some systems due to different OS configuration.

Configuration

The collection interval and the list of performance counters to be scraped can be configured:

windowsperfcounters:
  collection_interval: <duration> # default = "1m"
  initial_delay: <duration> # default = "1s"
  metrics:
    <metric name>:
      description: <description>
      unit: <unit type>
      gauge:
    <metric name>:
      description: <description>
      unit: <unit type>
      sum:
        aggregation: <cumulative or delta>
        monotonic: <true or false>
  perfcounters:
    - object: <object name>
      instances: [<instance name>]*
      counters:
        - name: <counter name>
          metric: <metric name>
          attributes:
            <key>: <value>

*Note instances can have several special values depending on the type of counter:

Value | Interpretation -- | -- Not specified | This is the only valid value if the counter has no instances "*" | All instances "_Total" | The "total" instance "instance1" | A single instance ["instance1", "instance2", ...] | A set of instances ["_Total", "instance1", "instance2", ...] | A set of instances including the "total" instance

Scraping at different frequencies

If you would like to scrape some counters at a different frequency than others, you can configure multiple windowsperfcounters receivers with different collection_interval values. For example:

receivers:
  windowsperfcounters/memory:
    metrics:
      bytes.committed:
        description: the number of bytes committed to memory
        unit: By
        gauge:
    collection_interval: 30s
    perfcounters:
      - object: Memory
        counters:
          - name: Committed Bytes
            metric: bytes.committed

  windowsperfcounters/processor:
    collection_interval: 1m
    metrics:
      processor.time:
        description: active and idle time of the processor
        unit: "%"
        gauge:
    perfcounters:
      - object: "Processor"
        instances: "*"
        counters:
          - name: "% Processor Time"
            metric: processor.time
            attributes:
              state: active
      - object: "Processor"
        instances: [1, 2]
        counters:
          - name: "% Idle Time"
            metric: processor.time
            attributes:
              state: idle

service:
  pipelines:
    metrics:
      receivers: [windowsperfcounters/memory, windowsperfcounters/processor]

Defining metric format

To report metrics in the desired output format, define a metric and reference it in the corresponding counter, along with any applicable attributes. The metric's data type can either be gauge (default) or sum.

| Field Name | Description | Value | Default | | -- | -- | -- | -- | | name | The key for the metric. | string | Counter Name | | description | definition of what the metric measures. | string | | | unit | what is being measured. | string | 1 | | sum | representation of a sum metric. | Sum Config | | | gauge | representation of a gauge metric. | Gauge Config | |

Sum Config

| Field Name | Description | Value | Default | | -- | -- | -- | -- | | aggregation | The type of aggregation temporality for the metric. | [cumulative or delta] | | | monotonic | whether or not the metric value can decrease. | false | |

Gauge Config

A gauge config currently accepts no settings. It is specified as an object for forwards compatibility.

e.g. To output the Memory/Committed Bytes counter as a metric with the name bytes.committed:

receivers:
  windowsperfcounters:
    metrics:
      bytes.committed:
        description: the number of bytes committed to memory
        unit: By
        gauge:
    collection_interval: 30s
    perfcounters:
    - object: Memory
      counters:
        - name: Committed Bytes
          metric: bytes.committed

service:
  pipelines:
    metrics:
      receivers: [windowsperfcounters]

Known Limitation

• The network interface is not available inside the container. Hence, the metrics for the object Network Interface aren't generated in that scenario. In the case of sub-process, it captures Network Interface metrics. There is a similar open issue in Github and Docker forum.
