Uninstalling the Enterprise Agent (Linux Package)

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 14.04

  1. Determine whether the te-agent and the te-browserbot services are running:

    $ service te-agent status
    te-agent start/running, process 4686
    $ service te-browserbot status
    te-browserbot start/running, process 4785
  2. Stop the te-agent and the te-browserbot services:

    $ sudo service te-agent stop
    te-agent stop/waiting
    $ sudo service te-browserbot stop
    te-browserbot stop/waiting
  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 the agent.

    $ sudo apt-get purge te-agent
    $ sudo apt-get purge te-browserbot
  4. Verify that both packages have been removed:

    $ service te-agent status
    te-agent: unrecognized service
    $ service te-browserbot status
    te-browserbot: unrecognized service

Ubuntu 16.04 and 18.04

  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:

    $ sudo service te-browserbot status

    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:

    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

    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: groupbrowserbot' 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.please

If you do not plan to replace the agent, you should remove it from the ThousandEyes platform. From the 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.
