This plugin collects NFS client statistics from any system that has NFS tools installed
Used for monitoring the rate of change in NFS ops
The intention for this plugin is to identify which hosts could be having slowness issues or problems with NFS.
This plugin is used in the [snap framework] (http://github.com/intelsdi-x/snap).
In order to use this plugin you need "nfs-client" to be installed on a Linux target host.
- Linux OS
- [nfs-client package] (#installation)
- golang 1.5+
To install sysstat package from the official repositories simply use:
- For Ubuntu, Debian:
sudo apt-get install nfs-client - For CentOS, Fedora:
sudo yum install nfs-client
Get the source by running a go get to fetch the code:
$ go get github.com/thomastaylor312/snap-plugin-collector-nfsclient
Build the plugin by running make within the cloned repo:
$ cd $GOPATH/src/github.com/thomastaylor312/snap-plugin-collector-nfsclient && make
This builds the plugin in /build/rootfs/
You can also download prebuilt binaries for OS X and Linux (64-bit) at the releases page
- Set up the snap framework
- Ensure
$SNAP_PATHis exported
export SNAP_PATH=$GOPATH/src/github.com/intelsdi-x/snap/build
By default iostat executable binary are searched in the directories named by the PATH environment.

This is still in progress
This plugin is still in active development. As we launch this plugin, we have a few items in mind for the next few releases:
- Add support for non-default NFS ports
- Additional error handling
