🥜 nitpick
You could update the config file name accordingly

💬 suggestion
Should be possible to run the request using the Docker client in

datadog-agent/test/new-e2e/pkg/environments/dockerhost.go

To be tested:

// stop
s.Env().Docker.GetClient().ContainerStop(context.Background(), "dd-snmp", container.StopOptions{})

// restart
s.Env().Docker.GetClient().ContainerRestart(context.Background(), s.Env().Agent.ContainerName, container.StopOptions{})

But I think you need to get the ID from the container name

Checked and indeed you would need to get the container ID, will create a card to provide this through the Docker client, we can generate a list of container ids by their name.

Yes I tried before to get the list of container ids filtered by the name and then get the first one from the list but it is maybe easier like this

require.NoError(s.T(), err)

_, err = s.Env().RemoteHost.Execute(fmt.Sprintf("docker restart %s", s.Env().Agent.ContainerName))
require.NoError(s.T(), err)

err = fakeintake.FlushServerAndResetAggregators()
require.NoError(s.T(), err)

var metrics []*aggregator.MetricSeries

require.EventuallyWithT(s.T(), func(t *assert.CollectT) {
metrics, err = fakeintake.FilterMetrics("snmp.device.reachable")
assert.NoError(t, err)
assert.NotEmpty(t, metrics)
}, 5*time.Minute, 5*time.Second)

tags := metrics[0].Tags

require.Zero(s.T(), metrics[0].Points[0].Value)
require.ElementsMatch(s.T(), tags, initialTags)
