Kibana: Kibana report timeout error on cloud

[liza-mae]

Kibana version:
6.5.0 - Cloud
Elasticsearch version:
6.5.0 - Cloud
Browser version:
Chrome

Original install method (e.g. download page, yum, from source, etc.):
Cloud

Describe the bug:
I am getting a timeout error on report generation:
Unable to generate report
TimeoutError: waiting for selector ".application" failed: timeout 30000ms exceeded

Is there a way to increase the time out ?

Steps to reproduce:

1. Create es/kibana cloud deployment
2. Add sample data
3. Generate PDF report from dashboards

Expected behavior:
Report generation should work

Screenshots (if relevant):

I increased the xpack.reporting.queue.timeout to 120000 and it worked, just curious in our documentation: https://www.elastic.co/guide/en/kibana/current/reporting-settings-kb.html we specify the default as 2 minutes - is the default for cloud different ?

[liza-mae]

Although one of the reports started and completed, the other one failed with max attempts reached.
This is for 2 minutes.

Experiencing the same issue. Setting xpack.reporting.queue.timeout in the cloud kibana settings doesn't fix it.

[joelgriffith]

I'd be helpful to know the size of both the reports and the instances that are running kibana. Large-ish PDF's can be a struggle to generate depending on the RAM available

[liza-mae]

@joelgriffith - I was using sample data when I received the error

[joelgriffith]

@liza-mae what's the size of the instance, in terms of memory GB and CPU? We've seen this timeout fairly frequently when RAM and/or CPU are constrained (and trying to run multiple reports at the same time... which it looks like what is happening in your screenshot).

[liza-mae]

@joelgriffith I use the default settings from staging, below is a pic:

[chrisdavies]

I would imagine that even if there are several reports queued up, it's only going to try to generate one at a time. That's the default behavior, I think. If so, then it's most likely a single report that's causing things to fall over.

[joelgriffith]

I haven't played much with the 1GB of RAM setup on 6.6.0... but I suspect that it's potentially a memory thing at play. I'll give it a shot locally and see what I find!

[liza-mae]

I have tried it on latest 6.6.0 and I get different errors - although sometimes it works sometimes not.

I'm still encountering this issue with 6.7. PDF export worked fine for me when I was running 6.5

[joelgriffith]

@timothy-gibson this is interesting. We've upgraded Chrome on 6.7 so it should be more stable. What's the size of the host (also any errors you're seeing)?

[timothy-gibson]

@joelgriffith currently running a HIGHIO.CLASSIC with 2GB of ram. The Kibana instance has 1GB of RAM. I would expect that this would work with this configuration given I didn't have any problems with exporting in 6.5.

Error Output:

I get this error on both single simple visualization exports and more complicated dashboard exports.

[joelgriffith]

@timothy-gibson it's probable that the newer version of Chromium that we've bundled with Kibana is performing slower than the prior one. We've also recently found a potential bug here: https://github.com/elastic/kibana/pull/34756/files, where certain navigation/waiting that happens in the browser defaults to 30 seconds regardless of what timeout is being set.

[timothy-gibson]

Thanks for the info @joelgriffith. Is there any known work around at this point for cloud instances? The only way I can put together reports at this point with our Kibana visualisations is by screenshot (which is not particularly high resolution), or embedding them externally in an iFrame.

[joelgriffith]

I'm trying to think of one, but unfortunately the only options are potentially downgrading back to your prior working version (not great), or waiting until the PR I linked get's merged then backported _then_ released (not great). Unfortunately downgrading Chromium is not something that I'd recommend, as when we _do_ update then issues could happen due to the version differences.

The only other possibility, at this point, is resizing the host so that it has more power to process. 4GB RAM + 2CPU's generally perform well for PDF generation, however it's still a possibility that you'd hit that same error.

Sorry -- I really do wish I had better suggestions. If something does hit I'll let you know!!

Hello. Has there been any further resolution to this issue?

[jgpereira23]

Also interested in knowing what was the resolution on this. Experiencing the same issue others are having. TimeoutError: waiting for selector "[data-test-subj="euiToastHeader"]" failed: timeout 30000ms exceeded

[syurdin]

I added a second Kibana node and it resolved the problem. But that costs
more money...

Hi - @jgpereira23 @syurdin this should be fixed with https://github.com/elastic/kibana/pull/34756 - what versions are you using ?

[timothy-gibson]

Hi, I've now upgraded to 6.8 and both PNG and PDF reports seem to be exporting okay
