Host Metrics Receiver

Status
Stability beta
Supported pipeline types metrics
Distributions core, contrib

The Host Metrics receiver generates metrics about the host system scraped from various sources. This is intended to be used when the collector is deployed as an agent.

Getting Started

The collection interval and the categories of metrics to be scraped can be configured:

hostmetrics:
  collection_interval: <duration> # default = 1m
  scrapers:
    <scraper1>:
    <scraper2>:
    ...

The available scrapers are:

Scraper Supported OSs Description
cpu All except Mac[1] CPU utilization metrics
disk All except Mac[1] Disk I/O metrics
load All CPU load metrics
filesystem All File System utilization metrics
memory All Memory utilization metrics
network All Network interface I/O metrics & TCP connection metrics
paging All Paging/Swap space utilization and I/O metrics
processes Linux Process count metrics
process Linux & Windows Per process CPU, Memory, and Disk I/O metrics
Notes

[1] Not supported on Mac when compiled without cgo which is the default.

Several scrapers support additional configuration:

Disk
disk:
  <include|exclude>:
    devices: [ <device name>, ... ]
    match_type: <strict|regexp>
File System
filesystem:
  <include_devices|exclude_devices>:
    devices: [ <device name>, ... ]
    match_type: <strict|regexp>
  <include_fs_types|exclude_fs_types>:
    fs_types: [ <filesystem type>, ... ]
    match_type: <strict|regexp>
  <include_mount_points|exclude_mount_points>:
    mount_points: [ <mount point>, ... ]
    match_type: <strict|regexp>
Load

cpu_average specifies whether to divide the average load by the reported number of logical CPUs (default: false).

load:
  cpu_average: <false|true>
Network
network:
  <include|exclude>:
    interfaces: [ <interface name>, ... ]
    match_type: <strict|regexp>
Process
process:
  <include|exclude>:
    names: [ <process name>, ... ]
    match_type: <strict|regexp>
  mute_process_name_error: <true|false>
  scrape_process_delay: <time>

Advanced Configuration

Filtering

If you are only interested in a subset of metrics from a particular source, it is recommended you use this receiver with the Filter Processor.

Different Frequencies

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

receivers:
  hostmetrics:
    collection_interval: 30s
    scrapers:
      cpu:
      memory:

  hostmetrics/disk:
    collection_interval: 1m
    scrapers:
      disk:
      filesystem:

service:
  pipelines:
    metrics:
      receivers: [hostmetrics, hostmetrics/disk]

Resource attributes

Currently, the hostmetrics receiver does not set any Resource attributes on the exported metrics. However, if you want to set Resource attributes, you can provide them via environment variables via the resourcedetection processor. For example, you can add the following resource attributes to adhere to Resource Semantic Conventions:

export OTEL_RESOURCE_ATTRIBUTES="service.name=<the name of your service>,service.namespace=<the namespace of your service>,service.instance.id=<uuid of the instance>"

Functions

func NewFactory

func NewFactory() component.ReceiverFactory

NewFactory creates a new factory for host metrics receiver.

Types

type Config

type Config struct {
	scraperhelper.ScraperControllerSettings `mapstructure:",squash"`
	Scrapers                                map[string]internal.Config `mapstructure:"-"`
}

Config defines configuration for HostMetrics receiver.

func (*Config) Unmarshal

func (cfg *Config) Unmarshal(componentParser *confmap.Conf) error

Unmarshal a config.Parser into the config struct.

func (*Config) Validate

func (cfg *Config) Validate() error

Validate checks the receiver configuration is valid

perfcounters
Package perfcounters is a thin wrapper around https://godoc.org/github.com/leoluk/perflib_exporter/perflib that provides functions to scrape raw performance counter data, without calculating rates or formatting them, from the registry.
