Host Metrics
When vector is run under kubernetes, you may experience an error when loading the partition usage data:
Failed to load partition usage data. mount_point="/host/proc/sys/fs/binfmt_misc" error=FFI function "statvfs" call failed: Too many levels of symbolic links (os error 40)
To work around this configuration issue, add one of the following lines to the
host_metrics configuration section:
filesystem.devices.excludes = ["binfmt_misc"],
filesystem.filesystems.excludes = ["binfmt_misc"], or
filesystem.mountpoints.excludes = ["*/proc/sys/fs/binfmt_misc"].
This workaround is included by default in the Helm chart distributed with Vector.
Configuration Options
Required Options
type(required)
The component type. This is a required field for all components and tells Vector which component to use.
| Type | Syntax | Default | Example |
|---|---|---|---|
| string | literal | ["host_metrics"] |
Advanced Options
collectors(optional)
The list of host metric collector services to use. Defaults to all collectors.
| Type | Syntax | Default | Example |
|---|---|---|---|
| array | literal | cgroupscpudiskfilesystemloadhostmemorynetwork | ["cgroups","cpu","disk","filesystem","load","host","memory","network"] |
namespace(optional)
The namespace of metrics. Disabled if empty.
| Type | Syntax | Default | Example |
|---|---|---|---|
| string | literal | host |
scrape_interval_secs(optional)
The interval between metric gathering, in seconds.
| Type | Syntax | Default | Example |
|---|---|---|---|
| uint | 15 |
cgroups(optional)
Options for the "cgroups" (controller groups) metrics collector.
Note: this collector is only available on Linux systems, and only supports either version 2 or hybrid cgroups.
| Type | Syntax | Default | Example |
|---|---|---|---|
| hash | literal | [] |
disk(optional)
Options for the "disk" metrics collector.
| Type | Syntax | Default | Example |
|---|---|---|---|
| hash | literal | [] |
filesystem(optional)
Options for the "filesystem" metrics collector.
| Type | Syntax | Default | Example |
|---|---|---|---|
| hash | literal | [] |
network(optional)
Options for the "network" metrics collector.
| Type | Syntax | Default | Example |
|---|---|---|---|
| hash | literal | [] |
How it Works
State
This component is stateless, meaning its behavior is consistent across each input.
Context
By default, the host_metrics source augments events with helpful
context keys.
