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.

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.

Configuration

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

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

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]

Scrapers

The available scrapers are:

Scraper	Supported OSs	Description
cpu	All	CPU utilization metrics
disk	All	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
processes	Linux	Process count metrics
swap	All	Swap space utilization and I/O metrics
process	Linux & Windows	Per process CPU, Memory, and Disk I/O metrics

Several scrapers support additional configuration:

  <include|exclude>:
    devices: [ <device name>, ... ]
    match_type: <strict|regexp>

File System

filesystem:
  <include|exclude>:
    devices: [ <device name>, ... ]
    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>
