DatabaseDataMonitor Service is not comming up.

Hello Experts,


I am facing DatabaseDataMonitor Service problem since I last rebotted NA server as users were facing application slowness issue. The service didnt came up and in details it shows following text:


Could not find a reporting task


Can anyone help me why I am facing this problem ? Also, I wanted to know how many users can simuntaneously work on NA console for configuration deployment and not face any application slowness issue.


Thanks in advance.

The error you are seeing is just a warning in fact. You are missing from the scheduled tasks a Generate Summary REport task (to re-occur daily).


Please add it as follows:


1. Reports > Reporting Tasks > Generate Summary Report (reoccurring options: Daily, Start at : your preferred time)

2. Rerun the monitor.


The performance issue is not related to the error you are seeing. There are a number of possible issues.

Please open a case with HP NA support to review your system/logs/DB and further investigate slowness issues.


Kind regards,

Hi Avi;


I did not see that there was a reply to this question and I wanted to make sure that you had your question answered.


To simply answer your question, there is no specific limitation in the number of users that a system can support.   It depends on a variety of environmental and applications variables that are put into place, such as size of memory, how much java memory is allocated, the number of concurrent tasks that are set in the application.   It really is a function of overall tuning. 


There are some resources that are available to you to help in determining how to size different aspects of Network Automation (NA).  Primarily, we have a document that can be found on the SSO called "NA Support Matrix"..   In NA Version 9.22, we've expanded this document to include a Tuning section.  This section makes recommendations based on testing different sized environments in our labs.    This document can be found at


I hope that this helps answer your question.

Thanks a lot Joe for making it to answer my query 🙂


Appretiate that !



Yes, I got my answer. Scalability depends on workload shared by NA on computer resources.


Thanks again !
