# Manage the Linux agent

This section describes how to start, stop and check the status of the `axolet` and `axoflow-otel-collector` services on Linux.

### Start the service

To start the `axolet` or `axoflow-otel-collector` service, execute the following commands:

  * `systemctl start axolet`
  * `systemctl start axoflow-otel-collector`



Alternatively, you can restart the service from AxoConsole:

  1. Find the host on the **Topology** or the **Sources** page. Alternatively, select `⌘/Ctrl + K` and enter the name of the host.
  2. Select the name of the host.
  3. Select **Services > Restart**.



### Stop the service

To stop the `axolet` or `axoflow-otel-collector` service, execute the following commands:

  * `systemctl stop axolet`
  * `systemctl stop axoflow-otel-collector`



### Check the status of the service

To check the status of the `axolet` or `axoflow-otel-collector` service, execute the following commands:

  * `systemctl status axolet`
  * `systemctl status axoflow-otel-collector`



For more detailed logs, run:

  * `journalctl -u axolet`
  * `journalctl -u axoflow-otel-collector`



## Upgrade Axoflow agent

AxoConsole raises an alert for the host when a new Axoflow agent version is available. To upgrade to the new version, re-run the one-liner installation command you used to install Axoflow agent, or select [**Provisioning > Select type and platform**](../../../docs/axoflow/provisioning/linux-agent/index.md) to create a new one (make sure to enable the **Advanced options > Install Collector agent** option).

Note that it can take a few minutes until the version numbers of the different services get updated on AxoConsole.
