Uninstalling the Enterprise Agent (Linux Package)

Due to recent platform-wide naming, navigation, and URL changes in the product, you may notice some discrepancies between the product and the screenshots displayed in our technical documentation. The instructions and actual pages in the product are still valid and haven’t changed. Please bear with us as we update our screenshots to better match the in-product experience. See the full scope of changes on Naming and Navigation Menu changes - Summary List.

Customers may need to remove the Enterprise Agent software which was installed on a supported Linux operating system from the te-agent and (optionally) te-browserbot packages. Additionally, customers may optionally remove the configuration files created by the agent. Customers may wish to keep the agent configuration files if the reason for removal is to fix a broken agent. Reinstalling agent software with existing configuration files allows the agent to resume running with the configuration of tests and other settings present prior to removing the agent software.

This article describes the steps required to remove an Enterprise Agent from each of the supported Linux distributions.

Ubuntu

1. Check if the te-agent and the te-browserbot services are running:

   $ sudo systemctl status te-agent
   ● te-agent.service - ThousandEyes Agent
      Loaded: loaded (/lib/systemd/system/te-agent.service; enabled; vendor preset:
      Active: active (running) since Tue 2017-04-04 12:11:49 CDT; 2min 5s ago
    Main PID: 1052 (te-agent)
       Tasks: 24
      Memory: 29.0M
         CPU: 1.182s
      CGroup: /system.slice/te-agent.service
              └─1052 /usr/local/bin/te-agent -C /etc/te-agent.cfg
   $ sudo service te-browserbot status
   ● te-browserbot.service - ThousandEyes BrowserBot
      Loaded: loaded (/lib/systemd/system/te-browserbot.service; enabled; vendor pr
      Active: active (running) since Tue 2017-04-04 12:12:16 CDT; 2min 17s ago
    Main PID: 1596 (java)
       Tasks: 90
      Memory: 162.0M
         CPU: 14.426s
      CGroup: /system.slice/te-browserbot.service

2. Stop the te-agent and the te-browserbot services:

   $ sudo systemctl stop te-agent
   $ sudo systemctl status te-agent
   ● te-agent.service - ThousandEyes Agent
      Loaded: loaded (/lib/systemd/system/te-agent.service; enabled; vendor preset:
      Active: inactive (dead) since Tue 2017-04-04 12:16:29 CDT; 9s ago
     Process: 3632 ExecStart=/usr/local/bin/te-agent -C /etc/te-agent.cfg (code=kil
    Main PID: 3632 (code=killed, signal=TERM)
   
   $ sudo systemctl stop te-browserbot
   $ sudo systemctl status te-browserbot
   ● te-browserbot.service - ThousandEyes BrowserBot
      Loaded: loaded (/lib/systemd/system/te-browserbot.service; enabled; vendor pr
      Active: inactive (dead) since Tue 2017-04-04 12:17:03 CDT; 8s ago
     Process: 3696 ExecStart=/usr/bin/java -Djava.io.tmpdir=/var/lib/te-browserbot/
    Main PID: 3696 (code=exited, status=143)

3. Purge the te-agent and the te-browserbot packages: If you're planning to re-install the agent software use "apt-get remove" instead of "apt-get purge". This will leave the necessary configuration files intact, so that once the agent is re-installed, there is no need to re-assign tests to it.

   $ sudo apt-get purge te-agent
   Removing te-agent (1.9.1-1~xenial) ...
   Updating certificates in /etc/ssl/certs...
   0 added, 0 removed; done.
   Running hooks in /etc/ca-certificates/update.d...
   
   done.
   done.
   Purging configuration files for te-agent (1.9.1-1~xenial) ...
   Updating certificates in /etc/ssl/certs...
   0 added, 0 removed; done.
   Running hooks in /etc/ca-certificates/update.d...
   
   done.
   done.
   
   
   $ sudo apt-get purge te-browserbot
   (Reading database ... 68880 files and directories currently installed.)
   Removing te-browserbot (1.38-1~xenial) ...
   Removing user `browserbot' ...
   Warning: group `browserbot' has no more members.
   Done.

4. Verify that both packages have been removed:

   $ sudo systemctl status te-agent
   ● te-agent.service
      Loaded: not-found (Reason: No such file or directory)
      Active: inactive (dead) since Tue 2017-04-04 12:16:29 CDT; 7min ago
    Main PID: 3632 (code=killed, signal=TERM)
   
   $ sudo systemctl status te-browserbot
   ● te-browserbot.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead) since Tue 2017-04-04 12:17:03 CDT; 7min ago
    Main PID: 3696 (code=exited, status=143)

Delete the Agent from the ThousandEyes Platform

If you have removed this agent with the expectation of replacing it, see Replacing an Enterprise Agent.

If you do not plan to replace the agent, you should remove it from the ThousandEyes platform. From the Network & App Synthetics > Agent Settings page, expand the agent's row, then click the More Actions icon and select Delete.

NOTE: Deleting an agent will remove it from any tests to which it was assigned, and any tests that have no other agents assigned will be disabled.
