My metcibeat yaml is following：

```

However，filesystem metricset can't get host filesystem statistics:

Hi @Jun_Zhang,

This is a current limitation of Metricbeat, can you please open a new enhancement request under [https://github.com/elastic/beats/issues](https://github.com/elastic/beats/issues)?

Best regards
