Monitorix is a lightweight http://www.aliyun.com/zixun/aggregation/13446.html "> system monitoring tool. can be used for UNIX servers, which can also be used on embedded devices because of their simplicity and small size. It consists primarily of two programs: a collector called Monitorix, a Perl daemon, similar to the automatic start of any other system service, and the other a CGI script called monitorix.cgi.
The Monitorix 2.3.0 version introduces two new interesting graphics to monitor NFS server and client statistics, and supports NFS versions 2,3 and 4. Add a new option $netstats_in_bps in the configuration file, this new option provides bits and bytes to switch between all network values per second. Another important change is the better support of the newer NVIDIA drivers.
