RPM Network Agent Operations

You install the Network Agent as part of an overall workflow for setting up Network Visibility. The three supported workflows are:

See Set Up Network Visibility on Linux.

Install the RPM Agent

  1. Check System Requirements. See Network Visibility Supported Environments.
  2. Stop each application of interest if it is monitored by an installed App Agent. You will restart each application after you install and set up the Network Agent.
  3. Verify that you have sudo or root access permissions on the machine where you want to install the Network Agent. (You do not need sudo or root access to run the Agent.)
  4. Open a command prompt on the host, enter the mount command, and check the mounted file system for the directory where you plan to install the Agent. The file system should not have the noexec and nsuid flags set.
  5. Download the network-agent package to the machine.
  6. Verify that you have sudo or root access permissions on the machine where you want to install the Agent.
  7. Download the Agent package to the machine.
  8. Open a terminal window and enter: sudo rpm -ivh <installer.rpm>
    The Network Agent software is installed under /opt/appdynamics/netviz.
  9. To start the Agent, enter: sudo service appd-netviz start
  10. Verify that the Network Agent is running: sudo service appd-netviz status
  11. If you experience any problems or issues, see FAQs for Network Visibility.
  12. If you are installing the Network Agent as part of aSet Up Network Visibility on Linux workflow, proceed to the next step in the workflow:

Administer the RPM Agent

You should run the following commands as a <network_agent_user> with permissions to configure and run the Agent on the host machine.

OperationCommandNotes
Start Agent 
sudo service appd-netviz start

If the Agent starts successfully, the following displays:

Starting appd-netviz (via systemctl): [ OK ]

Stop Agent 
sudo service appd-netviz stop

If the Agent stops successfully, the following displays:

Stopping appd-netviz (via systemctl): [ OK ]

Restart Agent 
sudo service appd-netviz restart

If the Agent restarts successfully, the following displays:

Stopping appd-netviz (via systemctl): [ OK ]

Check Agent status 
sudo service appd-netviz status

The following example illustrates status output:

Uninstall the RPM Agent

To uninstall the Network Agent, enter:

sudo rpm -e appd-netviz

This command generates no output. To confirm that the Agent is removed, enter the status command again: sudo service appd-netviz status
