Profiling systemd

tip

You can learn about how to run the Parca Agent binary; if you haven't already.

caution

To specify which service discovery to use for the Parca Agent, we use the following flags:

      --kubernetes              Discover containers running on this node to
                                profile automatically.
      --systemd-units=SYSTEMD-UNITS,...
                                systemd units to profile on this node.

By default, the Agent uses Kubernetes service discovery. So we need to disable it:

parca-agent \
  --http-address=":7071" \
  --node=systemd-test \
+  --kubernetes=false \
  --insecure

Profiling additional units​

To profile units, you just need to specify the name of the service in --systemd-units flag.

parca-agent \
  --http-address=":7071" \
  --node=systemd-test \
+  --systemd-units=docker.service,my-app.service \
  --kubernetes=false \
  --insecure

Now we can view the active profilers by visiting http://localhost:7071:
