prometheus-linux-nfsdv4-exporter - prometheus exporter for NFSv4 server.

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.

Prometheus metrics:

• nfsiobytesread Total of bytes read
• nfsiobyteswrite Total of bytes write
• nfsnetworkconnections Total amount of network connections
• nfsnetworknetcount Total amount of packets
• nfsnetworktcpcount Total amount of TCP packets
• nfsnetworkudpcount Total amount of UDP packets
• nfsreplycache_hits Number of cache hits
• nfsreplycache_misses Number of cache misses
• nfsreplycache_nocache Number of nocache
• nfsv4opdelegperclient Number of deleg operations per NFSv4 client
• nfsv4oplayoutperclient Number of layout operations per NFSv4 client
• nfsv4oplockperclient Number of lock operations per NFSv4 client
• nfsv4opopenperclient Number of open operations per NFSv4 client
