# nfsvis(1)

visualize performance of NFS statistics

## NAME

**nfsvis** - visualize performance of NFS statistics

## SYNOPSIS

**nfsvis** \[**-V**\] \[**-c** *version*\] \[**-m** *maxrate*\] \[**-s** *version*\] \[*pmview options*\]

## DESCRIPTION

**nfsvis** displays a three dimensional bar chart of NFS request statistics. The display is updated with new values retrieved from the target *host* or *archive* every *interval* seconds (default is 2 seconds).

Two blocks of statistics are displayed - one for the NFS server and one for the NFS client requests. The height of the bars is proportional to the rate at which the various request types are processed.

**nfsvis** generates a [**pmview**(1)](/pmview/1.md) configuration file, and passes most command line options to [**pmview**(1)](/pmview/1.md). Therefore, the command line options **-A**, **-a**, **-C**, **-h**, **-n**, **-O**, **-p**, **-S**, **-t**, **-T**, **-Z** and **-z**, and the user interface are described in the [**pmview**(1)](/pmview/1.md) man page.

## COMMAND LINE OPTIONS

The **nfsvis** specific options are:

- **-c**

  Monitor NFS *version* 2 or 3 client metrics.  The default is version 2.

- **-m**

  Use *maxrate* as the maximum NFS request rate over all classes of request, from which the height of the bars is computed.  This effectively specifies the height at which bars will be clipped.

- **-s**

  Monitor NFS *version* 2 or 3 server metrics.  The default is version 2.

- **-V**

  Verbose mode - output the generated [**pmview**(1)](/pmview/1.md) configuration file.

## FILES

- **$PCP\_VAR\_DIR/config/pmlogger/config.nfsvis**

  A [**pmlogger**(1)](/pmlogger/1.md) configuration file for **nfsvis** metrics.

- **$PCP\_SHARE\_DIR/lib/pmview-args**

  Shell procedures for parsing [**pmview**(1)](/pmview/1.md) command line options.

## PCP ENVIRONMENT

Environment variables with the prefix **PCP\_** are used to parameterize the file and directory names used by PCP. On each installation, the file */etc/pcp.conf* contains the local values for these variables. The **$PCP\_CONF** variable may be used to specify an alternative configuration file, as described in [**pcp.conf**(4)](/pcp.conf/4.md).
