prometheus-linux-nfsdv4-exporter It is a prometheus-exporter that reports basic metrics of NFSv4 clients from the server side. Since Linux Kernel 5.3, NFSv4 mount points have information reported inside the /proc/fs/nfsd/clients/, it is possible to retrieve some limited information of clients that are using NFSv4.
