Additionaly it is possible to configure custom tags that are applied to the metrics via `host_tags_template` or `service_tags_template`.
Depending on whether the write event was triggered on a service or host object, additional tags are added to the ElasticSearch entries.
A host metrics entry configured with the following `host_tags_template`:
```
host_tags_template = {
os_name = "$host.vars.os$"
custom_label = "A Custom Label"
list = [ "$host.groups$", "$host.vars.foo$" ]
}
```
Will in addition to the above mentioned lines also contain:
```
os_name = "Linux"
custom_label = "A Custom Label"
list = [ "group-A;linux-servers", "bar" ]
```
