I can't tell specifically what metrics you are comparing so I will give some general information.

Have you compared the disk usage info to what is reported by df? The fsstats metricset reports free, used, and total. The used is computed with total - free, but there is also a concept of available and possibly the other usage metric is showing total - available. If there's a difference we should align.

The network metrics reported by Metricbeat are the raw counters (total values) reported by the OS. In order to measure rates you need to differentiate. https://github.com/elastic/beats/issues/2783#issuecomment-331169736
