Error when exporting long pages to PDF

Hello,

One of my network engineers came to me today stating that when he tries to export to PDF he is getting an error message that "There was an error trying to export the page to PDF. Please try again later." He is trying to export the events from one of the device types for the past 3 months so it is probably hitting the 2k displayed events limiter. When I try it with a smaller subset of data it works fine and other pages work fine as well. I went into the logs and found this:

2017-02-14 16:03:28,826 [10] (0) ERROR Orion_ExportToPDF - (null) Unable to convert html into PDF file.

EO.Pdf.HtmlToPdfException: Conversion failed. Browser engine failed to render page. Failed on command 4 ---> System.Exception: Browser engine failed to render page. Failed on command 4

at Orion_ExportToPDF.ConvertHtmlIntoPdfFile(ThreadData threadData, String outFile, String htmlCodeToConvert, String applicationRoot)

But I'm not sure what to make of it. Any ideas? It doesn't seem like a big enough issue to open a ticket for so was hoping maybe someone here had seen this before. Is there a limit to how much data we can send to the PDF converter?

Environment: Windows Server 2012 R2 Orion Platform 2016.2.100, DPA 10.2.0, IVIM 2.1.2, NetPath 1.0.1, QoE 2.2.0, NPM 12.0.1, SAM 6.3.0, VNQM 4.2.4, SRM 6.3.0, NTA 3.11.0

Thanks,

Hi Silverback,

Thank you so much for the reply! I hadn't run across that particular help article in my searches. I tried changing the timing and it still gives the same error. I can actually reproduce it at the command line as well if I remote into the server and run the exporttopdfcmd.exe directly (supplying the input and output files manually.) I've tried updating the browser settings as some of the other help articles mentioned but I haven't tried removing the ExporttoPDF.aspx.cs template as described in this article (Error when trying to export page to PDF - SolarWinds Worldwide, LLC. Help and Support ) yet as I am not seeing that particular error message in the logs and it is working with smaller amounts of data. Actually the working with smaller amounts of data thing got my excited when I saw your post as it seemed a perfect fit.

I am wondering if I am wasting time trying to fix this as it appears they are depreciating it in 12.1.

Export to PDF feature

The Export to PDF button on dashboards is deprecated as of this release and will be removed in a future release. SolarWinds recommends that you use the Save as PDF functionality built into your browser.

Maybe I should move this to the bottom of my priority pile and hope the network engineer forgets about it and no one else notices

Good morning!

Once thing you could try is adjusting the timeouts on the PDF exporter. Take a look at the article below, and see if it can help you:

https://support.solarwinds.com/Success_Center/Network_Performance_Monitor_(NPM)/Adjust_PDF_timeouts_in_NPM_12

Hope it helps. Let us know how you get on!

If you access the page that you are trying to export by its usual URL plus

&printable=true

appended to the end, does the PDF export succeed?

Hi D09H,

Thanks for the response. Adding &printable=true to the end of the URL gives me a page cannot be displayed error... No webpage was found for the web address: http://solarwinds server/orion/netperfmon/events.aspx&printable=true

I think I'm going to close out this issue as I have advised the network engineer to just use the export to PDF in the browser or limit the returns to less then 500 and he was happy with that answer. The PDF export works fine as long as the data returned doesn't get to long.

Thanks for your help

Rob

No problem. Maybe try opening a ticket with support, they may have a fix for this which isn't on the Success Centre!

Incidentally, if you hit the 'save as PDF' option at the top of the report, when viewing the report in Orion, does the file get created?
