Telemetry Dashboard does not have data and reload fails

[Tony_Digitalrep]

I have gone over this a few times and cannot seem to solve the problem.

I installed the telemetry dashboard. 

The App, Data Connections and Tasks look right. 

When I run the tasks  TelemetryDashboard-2-Reload-Dashboard it fails with the following error.

2023-05-02 20:27:50 0530 FROM '[lib://TelemetryMetadata/engineInfos.csv]' (txt, utf8, embedded labels, delimiter is '`')
2023-05-02 20:27:50 Error: Cannot open file: 'lib://TelemetryMetadata/engineInfos.csv' (Native Path: ***

2023-05-02 20:27:50 Execution Failed
2023-05-02 20:27:50 Execution finished.

I cannot find this file on the system. I cannot find a folder called TelemetryMetadata.

When I run the TelemetryDashboard.exe with -test and -fetchmetadata -debug    I get...

Any help would be appreciated.

Hey there @Tony_Digitalrep ,

From what I recall from my last configuration, the folder TelemetryMetadata should be created in your shared folder (QMC > Service Cluster > Root folder)
Also, you can take a look at QMC > Data Connections > TelemetryMetadata to see where this path leads on your system

I hope this helps,
Riccardo

Hi @Tony_Digitalrep,

Suggest you refer to the online Help for Telemetry Logging and the Telemetry Dashboard entry in the Qlik Sense Admin Playbook to ensure you have things configured correctly.

Best Regards

The path is to my shared folder. I dropped security to make sure that permissions were not an issue. The problem is that TelemetryMetadata is not created.

That file is never created. 

When you try to do a TelemetryDashboard.exe -fetchmetadata  from an Administrative command prompt. You get the following...

Telemetry Dashboard has stopped working. A problem cause the program to stop working correctly. Windows will close the program and notify you if a solution is available.

This is what you see at the command line.

I went through these files again. I had done everything in the them.

The issue seems to be that the metadata is not created. The file that the following says it is trying to fetch 

\\QS01\Nodes$\TelemetryDashboard\metadata.tdm 

Is never created. 

The TelemetryDashboard.exe crashes with a windows error if run with -intialize (after the first intialization) or if run with -fetchmetadata  --  It works fine with -test.  If you delete the tasks, dataconnections and app and rerun the intialization, it works without

I started from scratch and reinstalled and checked everything.

When I ran the tasks, I got the same error. The engineInfos.csv file does not exist anywhere on the system. This is a single node implementation.
