Ed Schouten	a696830c38	Add a collector for NFS client statistics. ... This change adds a new collector called "nfs" that parses the contents of /proc/net/rpc/nfs and turns it into metrics. It can be used to inspect the number of operations per type, but also to keep an eye on an extraneous number of retransmissions, which may indicate connectivity issues. I've picked the name "nfs", as most operating systems use "nfs" for the client component and "nfsd" as the server component. If we want to add stats for the NFS server as well, we'd better call such a collector "nfsd".	2016-12-09 19:58:08 +01:00
