Number of processes seems much more normal right now. Also the reports are faster and cpu during processing is lower.
Is this just an update chrome version?

According to the profiler nothing is still running, but the container is still using 100% CPU. There's no special config, apart from license key and admin users and such

I also noticed that CPU usage is always high, even when no reports are being requested. It seems that the chrome render processes aren't quit after rendering. See this process list:

Some use 20 hours of CPU time and more..

We're running jsreport in a docker container in Azure App service. At the moment we have to restart the app service at least daily because of these errors:

Timeout when waiting for worker
Error: Timeout when waiting for worker
    at Timeout._onTimeout (/app/node_modules/@jsreport/advanced-workers/lib/pool.js:78:27)
    at listOnTimeout (node:internal/timers:557:17)
    at processTimers (node:internal/timers:500:7)

The only logentry is:
info +0 Render request 1226 queued for execution and waiting for availible worker

I can't determine what report is being requested because all report names are listed as 'anonymous'

Do you have any suggestions on where to start investigating the issue?

srijken

Thanks for fixing the link. But I still don't know what to enter there for development purposes?

Hi,

We have an enterprise license, and would like to run a development instance using docker containers in azure. What the correct way to setup the license key info?

This:
https://jsreport.net/learn/faq#how-to-apply-license-key

Links to: https://github.com/jsreport/jsreport/blob/master/docker/README.md#apply-license-key

resulting in a HTTP 404...

srijken

Is there an extension available that lets me do this? It would be nice to be able to save reports in git, and/or have some sort of deployment solution so we can also have versioning of the reports.

srijken

thanks again

One more question about jsreport win-install: How can I configure it to run in production instead of develop?

srijken

Thanks, that works

srijken

When running without IISNode it works as expected. This setup works for me just as well..

What's the best way to run jsreport as a windows service so that it starts op when the machine boots?

srijken

Tried both electron and electron-prebuilt. Currently electron is installed version 1.6.6.

Yeah it's configured with 2 cores right now. And I'm just rendering a Hello world, so the template shouldn't be intensive in any way.

I can't get electron-pdf rendering to work. Tried both electron and electron-prebuilt.

Is there anything I can change in the config or something to make it work? Better ways to debug this are also welcome..

This is about the only thing I can get out of the logs.

Thanks! I just wanted to make sure that we don't run into problems when the key gets used on both machines.

Hi,

How does the license key work, and how does it know whether it counts as a development server or not?

Do I have to set the key in the development server as well to be able to store more than 5 reports?

Thanks,
Sander

The api description states that authentication should be done using Basic authentication. This means that the token that gets sent only changes when the user or password is changed.

Aren't you afraid that this way this information can leak causing people to access reports they're not allowed to and/or consuming someone else's credits?

Are there any plans to set up an authentication mechanism that has a limited token lifetime, like OAuth 2.0 (with client credentials flow)?

Thanks,
Sander
