How to monitor your tasks executions and system plan in NPrinting 17, 18 and all higher versions

Article Number: 000026913 | Last Modified: 2019/08/21

Description

Description:
  • NPrinting 17, 18 and all higher versions contain a hidden monitoring link that shows the status of executions within the current system admin plan. It is not possible to access it directly from the application because the feature is still in beta, but it can be very helpful for troubleshooting purposes.
  • Currently there is not other method for monitoring NPrinting tasks and/or system. A Feature Request (see below) has been registered for being able to monitor via SNMP.

Environment:
  • NPrinting 17, 18 and all higher versions

Cause

Feature Request ID(s):
  • ID - 991: SNMP Support for NPrinting (or at Platform level)

Resolution

Resolution
  • It is also possible to access a plan monitor at this link:
  • https://SERVERNAME:4993/#/admin/plan
Parameters Definitions for Admin Plan queue:
  • WORKLOAD: This is time expected for a single navigator/connection to resolve all the requests still present in the queue. It is expressed in milliseconds.
  • So, considering the data collected in previous task runs, NPrinting estimates how long each request will take. Then, it sums all these values.
    The estimation is done considering only one navigator working on the requests.
    A default value is given if it is the first time the connection runs.
  • PRIORITIZED WORKLOAD: It is the same as before, but each request time is multiplied by a coefficient between 1 and 11. The coefficient is assigned by NPrinting to each request according to its priority.
For example: If it is an On-Demand request, the coefficient is always 11 (the maximum), if there is a cycle in the report, we increase all the coefficient by 1. The coefficient are defined by internal algorithms in NPrinting.
  • CONNECTION WEIGHT: It calculates the 'keep alive' time of a navigator/connection. The value increases exponentially in time when a connection with requests has not a navigator opened for it. As soon as a navigator is opened for the connection, the value starts to decrease.
  • WEIGHTED WORKLOAD: It is the CONNECTION WEIGHT multiplied by the PRIORITIZED WORKLOAD. It is the priority assigned to the connection.
  • Engine Column (last column of Admin Plan): First 4 Alphanumeric Chars of the Engine GUID appear in this column. The full GUID for the NP Engine can be found by searching the NP Engine Log file for “Engine ID”
1st number: number of navigators going to be opened 
2nd number: number of navigators open
3rd number: closed navigators
Final number: the number of connections/navigators that will remain open/active once the process is completed

Yellow - indicates moving to closed. 
Blue - indicates moving connection/navigator to open.
Black - indicates waiting or working. 
Final number: the number of connections/navigators that will remain open/active once the process is completed

NOTE: Navigator Connections are internal processes within a single NP connection. For example, a single NPrinting Interface Connection to a QlikView or Qlik Sense document can have multiple internal navigator/connections. These are shown in the admin plan mentioned above. The number of internal navigator connections is limited to the number of cores on the NP engine computer.
ie: Depending on the complexity of the report (number of requests in play) 8 cores installed on a NP engine computer may result in up to 8 navigator connections opened in order to process a NPrinting report or reports. 

NOTE:
  • Task Execution and On Demand Execution are now available at the following links in the NP Web Console Since Nov. 2018 Release v18.39.6.0.
  • https://qlikserver3.domain.local:4993/#/tasks/executions
  • https://qlikserver3.domain.local:4993/#/admin/ondemand
  • Both of these links are available in the NP web console by click the 'Admin' menu option
