PROBLEM DESCRIPTION

This article explains how you can use the Detail column in Xmanager to display useful data such as user information and server load.

RESOLUTION

Xmanager displays the Willing message received from the remote host on the detail column. This message can be configured by users to send useful information from the server.

The following example shows you can configure the Willing message using gdm and gdm-binary:

1. Add the following line in /etc/gdm/gdm.conf or /etc/gdm/gdm/custom.conf:

   Willing=/etc/gdm/Xwilling

2. Create /etc/gdm/Xwilling and add the following lines:

   #!/bin/sh
   load="`uptime|sed -e 's/^.*load[^0-9]*//'`"
   nrusers="`who|cut -c 1-8|sort -u|wc -l|sed 's/^[ ]*//'`"
   s=""; [ "$nrusers" != 1 ] && s=s
   echo "${nrusers} user${s}, load: ${load}"

3. Change the permission on /etc/gdm/Xwilling
   

   chmod a+x /etc/gdm/Xwilling

4. Check Xmanager for Xwilling information
