# Frequently Asked Questions

## Q: How can I monitor the Docker Engine Host from within a container?

You will need to setup several volume mounts as well as some environment
variables:

```shell
docker run --name telegraf \
    -v /:/hostfs:ro \
    -e HOST_ETC=/hostfs/etc \
    -e HOST_PROC=/hostfs/proc \
    -e HOST_SYS=/hostfs/sys \
    -e HOST_VAR=/hostfs/var \
    -e HOST_RUN=/hostfs/run \
    -e HOST_MOUNT_PREFIX=/hostfs \
    telegraf
```

## Q: Why do I get a "no such host" error resolving hostnames that other programs can resolve?
