Monitoring of Tasks that reload Apps in Qlik Sense.
One or more tasks are scheduled on the Qlik server that automatically load the Apps,
The goal is to be able to query the status of a task with the help of REST API technology and integrate it with the PRTG monitoring system.
Step 1 -> Creation of a dedicated Virtual Proxy in Qlik QMC.
The documentation to be able to proceed is available from the following link:
Step 2 -> API Query Mode and Test.
Once the JWT virtual proxy has been configured and the validity of the Token has been verified as per the official guide, it is possible to proceed with the desired query.
NB. In this case we validated the token using a Service user who also runs all the dedicated services including the Proxy Service.
In this case we will monitor the correct reload of the tasks on the QLIK server, the Tasks are scheduled on the server and allow the App data to be reloaded.
When one of these tasks fails via API call, it is possible to have a json result with the related details inside.
Below is an example of an API call:
This is an example of a task we want to monitor:
A quick method to test if the call was successful is from the browser using the Mode Header extension for google chrome described in step 1.
https://chrome.google.com/webstore/detail/modheader-modify-http-hea/idgpnmonknjnojddfkpgkljpfnnfcklj
So for the call to be successful you need to pass the following parameters:
Where Header name: Authorization and Header value: Bearer followed by the previously generated and tested Token and finally the Xrfkey key.
This will be the result in Json format returned by the browser if the call is successful:
Specifically in PRTG what we are going to monitor is:
"startTime": "2022-05-04T07:46:34.100Z"
"stopTime": "2022-05-04T07:46:37.636Z"
3. Other information that we may integrate and otherwise see in PRTG.
NB. A table with Qlik Sense reload task status codes and descriptions is available from the following link
https://help.qlik.com/en-US/alerting/July2023/Content/QlikAlerting/system-alerts.htm
This is an example of the string JSON with ok API call.
Step 3 -> Task monitoring from PRTG.
Type of sensor used in PRTG.
How to create a sensor.
The path on the PRTG server where the template is to be uploaded is as follows:
C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\rest
In the following path, however, it is necessary to define a Lookups in order to allow the sensor to interpret the various states of the Qlik Tasks listed in Step 2.
C:\Program Files (x86)\PRTG Network Monitor\lookups\custom
Result JSON query Task from Browser a part of this information will be used for the sensor in PRTG each task will correspond to a specific sensor.
The REST Custom Sensor was used in PRTG.
The REST Custom sensor queries a Representational State Transfer (REST) application programming interface (API) endpoint and maps the JavaScript Object Notation (JSON) or Extensible Markup Language (XML) result to the sensor values the mapping rule must be available as a REST configuration file in JSON template format (*.template) according to the PRTG API definition for custom sensors.
Two files have been created on the PRTG server.
Final integration flow monitoring Task PRTG -> QLIK.
Following upgrade from Qlikview 11.2 to 12.7, we've noticed that Access Point previously showed the qvw file name in mixed case, but now has in lower case.
Following screenshot shows example on old/new version.
Is there any way to revert to mixed case on latest version?
The attached Migration Playbook is intended to be a consolidation of references for those who are on a QlikView NPrinting 16 to Qlik NPrinting 19 migration journey. It includes migration content from Qlik Community Posts, Qlik YouTube Channels, Qlik Support articles, Qlik Help site references, and guidance from the Qlik NPrinting product team. Read it from front to back or just selectively review the sections that relate to you - I hope you find this useful!
Reminder - this is relevant to QlikView NPrinting 16 customers only. If you are on Qlik NPrinting 17+ this guide is not for you.
