Host Metrics Receiver

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.

Supported pipeline types: metrics

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>

Network

network:
  <include|exclude>:
    interfaces: [ <interface name>, ... ]
    match_type: <strict|regexp>

Process

process:
  disk:
    <include|exclude>:
      names: [ <process name>, ... ]
      match_type: <strict|regexp>

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]
