Upgrading Agent via Wazuh Dashboard

[Arby Malabo]

Hello Everyone,

Is there a way to upgrade endpoint agents via wazuh dashboard?, it's a pain to go to each endpoint to manually upgrade the agent.

Hello Arby,

It is possible to upgrade agents from the Wazuh dashboard using the API Console.

Kindly navigate to Tools > API Console paste the API command PUT /agents/upgrade?agents_list=all&pretty=true and click the play button (screenshot attached).
If you want to check the upgrade status, paste the API command GET /agents/upgrade_result and click on the play button.

When upgrading more than 3000 agents at the same time, it's highly recommended to use the parameter wait_for_complete set to true to avoid a possible API timeout.
Example: PUT /agents/upgrade?agents_list=all&wait_for_complete=true&pretty=true

You can also try to upgrade specific agents by using their agent IDs separated with a comma.
Example: PUT /agents/upgrade?agents_list=005,007&pretty=true

Note: This number of agents from which wait_for_complete=true is recommended, has been set after testing the endpoint in a Wazuh environment whose manager was installed in a host with specifications: 2.5 GHz AMD EPYC 7000 series processor and 4 GiB of memory.
Using an agents list with a size less than or equal to 3000 and a host with the same or higher specs guarantees this endpoint to return a response before the API timeout.

You can also check this link for more information and other methods of remotely upgrading agents: Agent remote upgrade.

I hope you find this helpful!

Hi Pacome,

Just a follow-up question, if I run this command "PUT /agents/upgrade?agents_list=all&pretty=true" when some agents are offline, will the offline agents be upgraded when they get back online?. or should I run the command again?
