### 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:
|
|
```
|
|
docker run --name telegraf
|
|
-v /:/hostfs:ro
|
|
-v /etc:/hostfs/etc:ro
|
|
-v /proc:/hostfs/proc:ro
|
|
-v /sys:/hostfs/sys:ro
|
|
-v /var:/hostfs/var:ro
|
|
-v /run:/hostfs/run: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?
|
|
|
|
Go uses a pure Go resolver by default for [name resolution](https://golang.org/pkg/net/#hdr-Name_Resolution).
|
|
This resolver behaves differently than the C library functions but is more
|
|
efficient when used with the Go runtime.
|
|
|
|
If you encounter problems or want to use more advanced name resolution methods
|
|
that are unsupported by the pure Go resolver, you can switch to the cgo
|
|
resolver.
|
|
|
|
If running manually set:
|
|
```
|
|
export GODEBUG=netdns=cgo
|
|
```
|
|
|
|
If running as a service add the environment variable to `/etc/default/telegraf`:
|
|
```
|
|
GODEBUG=netdns=cgo
|
|
```
|
|
|
|
### Q: When will the next version be released?
|
|
|
|
The latest release date estimate can be viewed on the
|
|
[milestones](https://github.com/influxdata/telegraf/milestones) page.
