This feature is available as part of the Honeycomb Enterprise and Pro plans.
OpenTelemetry Collector can be deployed as an agent running on individual hosts, where it will regularly collect and forward diagnostic information about the system it runs on. For example, it can collect regular samples of CPU, memory, disk, and network utilization so that this data can be visualized in a Honeycomb query. These instructions describe how to install and run OpenTelemetry Collector in this way, and send the data it collects into Honeycomb.
OpenTelemetry Collector can be widely deployed across all your hosts as an agent. It can then be configured to scrape a specific set of system metrics at a regular interval (for example, once every 10 seconds), batch that data, and forward it to Honeycomb for querying and display. Each data point will be tagged with information about the host it was collected from, so that you can calculate aggregations across arbitrary subsets of production hosts.
The easiest way to get started collecting host metrics is by using one of our Collector binaries.
Download a binary that is compatible with your system, along with the
Run the binary with the command below.
xxxxx with your API key,
hostmetrics with the name of the dataset you would like to send metrics to,
otelcol_hny_linux_amd64 with the path to the binary you are using,
foozle with your service name, and
production with your environment:
HNY_API_KEY=xxxxx \ HNY_DATASET=hostmetrics \ OTEL_RESOURCE_ATTRIBUTES='service.name=foozle,deployment.environment=production' \ ./otelcol_hny_linux_amd64 --config ./honeycomb-metrics-config.yaml
A process will start and begin sending metrics to your dataset every 10 seconds.
You can add custom resource attributes to all your data points by changing the
OTEL_RESOURCE_ATTRIBUTES environment variable.
Attributes are separated by the comma character (
(See more information about attributes and this environment variable.)
If your host is deployed using Docker, Google Cloud, Google Kubernetes Engine, Amazon EC2, Amazon ECS, Amazon Elastic Beanstalk, Amazon EKS, or Azure, you can utilize the resource detection processor to automatically add metadata about the host to every metric data point.
(See more information about the resource detection processor.)
To enable the resource detection processor, edit the configuration file and add a value from the list below to

It is possible to use a different build of OpenTelemetry Collector to send host metrics to Honeycomb.
If you do this, we still recommend using our
honeycomb-metrics-config.yaml file as a basis for your configuration, since it is designed to keep your event volume low while providing you with as much data as possible in each event.
