Setup eBPF Profiling on Docker

To set up eBPF profiling with Grafana Agent on Linux, you need to:

  • Verify that your system meets the requirements.
  • Create a Grafana Agent configuration file. For more information, refer to the Configuration reference.
  • Run Grafana Agent or Grafana Alloy.
  • Verify that profiles are received.

Caution

Grafana Alloy is the new name for our distribution of the OTel collector. Grafana Agent has been deprecated and is in Long-Term Support (LTS) through October 31, 2025. Grafana Agent will reach an End-of-Life (EOL) on November 1, 2025. Read more about why we recommend migrating to Grafana Alloy.

Prerequisites

Before you begin, you need:

Note

If you don’t have a Grafana and/or a Pyroscope server, you can use the [Grafana Cloud][gcloud] free plan to get started.

Verify system meets the requirements

The eBPF profiler requires a Linux kernel version >= 4.9 (due to BPF_PROG_TYPE_PERF_EVENT).

BPF_PROG_TYPE_PERF_EVENT is a type of eBPF program that can be attached to hardware or software events, such as performance monitoring counters or tracepoints, in the Linux kernel.

To print the kernel version of your docker host, run:

shell
docker info | grep Kernel

Make sure you have a kernel version >= 4.9.

Configure Grafana Agent

You can configure the Grafana Agent eBPF profiler to profile local containers. To do so, use the discovery.docker component to discover local containers and the pyroscope.ebpf component to profile them.

Create a file named agent.river with the following content:

river
discovery.docker "local_containers" {
 host = "unix:///var/run/docker.sock"
}

pyroscope.ebpf "instance" {
 forward_to     = [pyroscope.write.endpoint.receiver]
 targets = discovery.docker.local_containers.targets
}


pyroscope.write "endpoint" {
 endpoint {
  basic_auth {
   password = "<PASSWORD>"
   username = "<USERNAME>"
  }
  url = "<URL>"
 }
 external_labels = {
  "env"      = "testing",
  "instance" = env("HOSTNAME"),
 }
}

Replace the <URL> placeholder with the appropriate server URL. This could be the Grafana Cloud URL or your own custom Pyroscope server URL.

If you need to send data to Grafana Cloud, you’ll have to configure HTTP Basic authentication. Replace <User> with your Grafana Cloud stack user and <Password> with your Grafana Cloud API key.

Note

If you’re using your own Pyroscope server, you can remove the basic_auth section altogether.

For more information, refer to the Configure the Grafana Pyroscope data source documentation.

Start Grafana Agent

To start Grafana Agent with Docker, run:

shell
docker run \
  -e AGENT_MODE=flow \
  -v $PWD/agent.river:/etc/agent/config.river \
  -v /var/run/docker.sock:/var/run/docker.sock \
  --pid=host \
  --privileged \
  -p 12345:12345 \
  grafana/agent:latest \
    run --server.http.listen-addr=0.0.0.0:12345 /etc/agent/config.river

Note: The --pid=host and --privileged flags are required to profile local containers with ebpf.

Verify profiles are received

To verify that the profiles are received by the Pyroscope server, go to the Pyroscope UI or Grafana Pyroscope datasource. Then select a profile type and a service from the dropdown menu.
