Monitoring network performance

In this recipe, we'll look at the following network metrics:

• network.interface.collisions
• network.interface.in.bytes
• network.interface.in.packets
• network.interface.in.errors
• network.interface.in.drops
• network.interface.out.bytes
• network.interface.out.packets
• network.interface.out.errors
• network.interface.out.drops

How to do it…

Now, one last time, we'll look at how we can create a text and graphical representation of data. Perform the following steps:

1. Display live data for the preceding metrics; run the following command:

   ~]# pmdumptext -H -t 1 -i -l network.interface.collisions network.interface.in.bytes network.interface.in.packets network.interface.in.errors network.interface.in.drops network.interface.out.bytes network.interface.out.packets network.interface.out.errors network.interface.out.drops -h guest.example.com
   

   
2. Create a configuration file for pmchart to display live data called network.conf with the following contents:

   #kmchart
   version 1
   
   chart...
