Monitoring Application - Reload fails with error "Exception of type 'System.OutOfMemoryException' on monitor_apps_REST_appobject

Bastien_Laugiero — Tue, 07 Nov 2023 08:37:21 GMT

Monitoring applications reload (Operation Monitor or Session Monitor) fails all of a sudden with error:

Error: HTTP protocol error 500 (Internal Server Error):
Exception of type 'System.OutOfMemoryException' was thrown.

Looking several lines above you can identify what was the last Data Connection in use:

If the last connection opened was 'monitor_apps_REST_appobject' then it means that there are too many AppObject to load and the system is going out of memory.

Resolution

To work around this issue, it is possible to implement a filter in the data connection 'monitor_apps_REST_appobject' to reduce the amount of application object loaded.

To do so:

Open the Qlik Sense Management Console
Open Data Connections
Edit the Data Connection exhibiting the issue and view the Connection String. The default string will include https://localhost/qrs/app/object/full, which retrieves a full list of app objects.
Modify the filter to only obtain a specific AppObject type, such as 'sheet':
https://localhost/qrs/app/object/full?filter=objectType+eq+'sheet'

Hello, I'm currently trying to filter more than one Object Type, how would the url be?

Would it be something like this? https://localhost/qrs/app/object/full?filter=objectType+eq+'sheet'+or+'treemap' (this URL doesn't work but it's what I've been testing).

Best regards,

Guillermo Cornec.

Hello @GCornec

I'd recommend posting about this directly in our forums (not specifically the article topic, but your query on trying to get two filters to work). I'll also be reaching out internally to see if I can find an answer for you, but the forum is the best bet.

Initially, these were the comments I gathered:

Can you try to verify if the treemap object type works individually? So, only filter for it
Can you see if using brackets () to divide them helps? See this for a similar example.

All the best,
Sonja
