Qlik Sense Engine Health Check doesn't refresh

[dmnrp]

Hello, 

I'm developing a Qlik's Health status dashboard and I'm using the endpoint health check to get the data: https://help.qlik.com/en-US/sense-developer/November2018/Subsystems/EngineAPI/Content/Sense_EngineAP...

I've created a REST connection but only works the first time that I reload it. Everytime that I reload the app I always get the same data (no change) but if I put in browser https://server/engine/healthcheck/ and then refresh the app I get new data.

I think that REST Connector has a bug and It save previous state, not refresh

I also try using POSTMAN and works fine like browser

Does anybody also happen to? did anybody try developing engine status dashboard?

Regards

Hello:

I have done exactly the same and got the same result. The request doesn't refresh or the result gets cached and is not able to refresh the values. 

Regards.

Are you using the Qlik REST Connector, @Contractor ?

I am seeing similar behavior on any call which goes over QPS rather than directly to the Engine. I've pinged Qlik Support about it.

Hi LeviTurner,

Yes, I have used the REST connector using the appropriate URL targeting to the main server and even pointing directly to the engine (using default port) but without success.

Any clue about it?

Thanks and kind regards.

It's caused by caching at the Proxy level. See https://support.qlik.com/articles/000082982 for a pointer towards resolution.

Try set your query headers on your REST Data Connections:

Name : Cache-control   Value : max-age=0

or

Name : Cache-control   Value : no-cache
