Export/Download Data

[Mohammed Alzaabi]

Hello Yamcs Team,

I am trying to export a values of some parameters. So I created a display of the list of parameters I would like to export. Then, I click on the three dots and then Export archive data. Based on the old version of Yamcs , I expect a csv file of the values. This time, however, a replay service is initiated. The terminal shows:

13:33:14.761 elr [25] ProcessorFactory [ParameterArchive-backfilling_1] Loading processor service ReplaySer
vice
13:33:14.762 elr [25] Processor Creating new processor 'ParameterArchive-backfilling_1' of type 'ParameterA
rchive'
13:33:14.825 elr [42] Processor [ParameterArchive-backfilling_1] Processor ParameterArchive-backfilling_1 q
uitting
13:33:14.825 elr [42] Processor [ParameterArchive-backfilling_1] Processor ParameterArchive-backfilling_1 i
s out of business

Is the export data has changed? or do I need to enable a service to be able to export the data? My current Yamcs version is 5.6.3.

Thank you

Download while viewing a *.par file 'should' still work, and yes it uses a replay processor.

However the log excerpt that you pasted comes from backfilling, which is unrelated to downloads. Maybe there's an error before or after?

Here's an example of nominal output:

Hi,

Yes you are right. Below you can see the full log once I click on the Export archive data:

Please note that I replaced some text with X's such as the instance name and the list of parameters.

So with this, I can't see a csv file downloaded.

Thank you

Please note that I am using Firefox on Ubuntu. I also tried Chrome on the same machine. With Chrome, the browser seems like it tries to download a file named parameter_export_2022-06-29_11-48-40.csv but it remains in the "starting" stage of the download.

Does it reproduce having only a single parameter in your par file? Any parameter?

[fabia...@spaceapplications.com]

And also curious if other downloads work, for example an event or packet download.

[Mohammed Alzaabi]

Yes, the same thing happens when the .par has one parameter only

[Mohammed Alzaabi]

Downloading packets and events work without issues and I was able to download the dumps.

[Yago Isasi Parache]

I can confirm that I am also facing the issue described by Mr. Alzaabi with several and one parameters. In my case is with the YAMCS version 5.5.1 and using Microsoft Edge.

Is any specific  sql-query template that can be used on the shell to download directly the data?. Could not find information about that,...

Can you both please when running the request which gets stuck, send a kill -3 <yamcs-pid> and send me the stack trace that is printed in the Yamcs standard output?
