The extension is not downloaded to ActiveGate

[Yamis]

I have created my first extension2.0 to scrape a Prometheus OpenMetrics endpoint but before I can reap the rewards of my labour it looks like I'm getting stuck near the very end.

ActiveGate 1.263.143 is deployed onto a Linux host.

The extension never gets pushed to the ActiveGate, even hours after being submitted.

Failed to assign monitoring configuration to ActiveGate. Reason: Extension custom:ome.extension(0.0.1) not available in cache yet (queued for download)
Failed to assign monitoring configuration to ActiveGate. Reason: Cannot extract extension from /var/lib/dynatrace/remotepluginmodule/agent/runtime/extensions/download/custom_ome.extension: checking signature failed

I'm not sure where to go to find out more detail in the logs.

Any help appreciated - thanks.

Hi,

Extension's logs are in "/var/lib/dynatrace/remotepluginmodule<CONFIG>/remotepluginmodule" following this link.

I would check if all folder and sub-folders in "/opt/dynatrace/remotepluginmodule<INSTALL>/remotepluginmodule" have correct permisions and I would restart extension service.

You can check also troubleshoot extensions documentation.

Best regards

Hi,

Have you made sure to upload your certificate that was used to sign the extension to the ActiveGate Host, it needs to be present in the credential vault as well as in all of the ActiveGate Hosts that will run the extension?https://www.dynatrace.com/support/help/shortlink/sign-extension#upload

This is indeed the cause of that error.

Awesome thanks folks!

That did indeed fix it, on to the next hurdle 🙂

It's a complicated process but I can see the security benefits.
