[Fleet] Give the ability to set up elastic agent download timeout

[jlind23]

As part of the policy we should give the ability to the customer to set up "agent.download.timeout: 10s" through the UI instead of letting them do it in the fleet.yml config.

Fleet UI enhancements:

1. agent.download.timeout to be configurable via UI. the default value set to 10minutes
2. NEW: a configurable interval to log an informational "progression" event which tracks the download transmission rate and percentage completed. Default set to every 1 minute. this variable currently doesn't exist and will be implemented.

@mostlyjason Could be interesting to expose agent settings at the policy level for:

• download timeout (this issue)
• download source URI ([Fleet] Ability to configure agent.download.sourceURI in Kibana #100413)
• auto-upgrading agents ([Fleet] Automatic Agent Upgrade option in Agent Policy #120735)

Hi @jlind23 !
Are there any updates on this one?

About 30% of our elastic agents can't upgrade due to poor internet connection plus download timeout being very low currently (120s). I haven't found a way to modify this setting via fleet either.

Would be lovely to have this in the UI.

Hi @nickbabkin,

Did you recently try the new rolling upgrade feature in order to release the network pressure?
Plus, AFAIR, @blakerouse changed this default timeout to 10minutes.

Hi @jlind23,

Yes we did, we are geographically distributed and unfortunately in some regions connection is so poor that 150 Mb can't be downloaded within 2 minutes.

In what version was download timeout changed to 10 minutes? Maybe I have to manually upgrade our agents to that one first.

Hi @nickbabkin the default to 10min was introduced by this PR: elastic/elastic-agent#308
It should be available from 8.3 on.

[nickbabkin]

@jlind23 lovely, thanks!
Now I need to find a way to update stuck agents manually to 8.3, and going forward from there I will be upgrading them via Fleet.

We are running 8.4.1 version of the elastic agent here. I am trying to upgrade an agent from 8.4.1 to 8.4.2 and the agent download is taking more than 10 minutes from an internal artifacts location. How do I increase the timeout from 10 minutes to a higher number?

We are running a geographically distributed company and aren't able to download the agent binaries in 10 minutes too. We would also love to have the ability to set download timeout from the UI.
