Link to current version of Zabbix agent MSI

[troffasky]

A permalink to the current version of the Zabbix agent MSI would be useful for scripting, etc.

Are you thinking about creating agent self update script? If so I would advice against it. It is better to use higher server version than the agent version and not the other way arround. As the backwards compatibility works from server to agent.
Once you update server you know which version of the agent you are going to use.

+1 for Blevar.

however if You still would like to pursue this, You might want to monitor the CDN for newer versions:

https://cdn.zabbix.com/zabbix/binaries/stable/

Clarifying that this is true when dealing with major versions, ie. 7.0 vs 7.2. For minor versions, not so much. We update agents minor versions more frequently than the server's and have never run into any problems. Same thing with proxies and servers, they should be of the same major version.

This is not for automatic updates, this is for initial install so we don't have to edit install scripts when we want to start installing a newer version.
msiexec is happy to follow redirects, so we just stuck a redirect on example.com/zabbxagent.msi to the current version and use that in scripts. That's good enough for me.
I am not clear on the logic of choosing a different server/agent versions.

I've used wildly different versions without any obvious ill effect [today I am deleting a bunch of hosts with 7.2.2 from a server running 4.4.10] . I know it's "not supported", but I don't pay for support anyway, so don't really care.

I agree, perpetual Evergreen download links for the latest agent versions should be made available. It is a simple easy thing to do.

Even the names contain "latest"...

[gherbstman]

That link is helpful indeed. However, you still need figure out your exact download URL. To that end, I wrote a PowerShell function that will get you the latest download link from the CDN for specific trains and windows architecture. It will also optionally download the MSI installer to a location of your choice.

Yeah, I guess that's close enough. Seeing as this exists, I do wonder why the documentation points to specific sub-versions and not just the /latest/ URL.

There is option to choose certain version... They could probably include "latest" in that list.. But noone has pointed it out yet...

[troffasky]

They seem to have disappeared today.

[cyber]

who knows... seems there is no windows agents in any of subdirs there.. 7.4.0, 7.4.1 , latest...

[dzidek23]

I came here to ask exactly this question.
Where are all of the Windows Installers?

Windows is also gone from OS selection list in zabbix dowload page.

[troffasky]

And disappeared from install instructions page. Intriguing. Is there a terrible CVE incoming?
