Issue/Introduction

Items are note seen in the NetOps Portal user interface when looking at the device on the Data Aggregator (Administration > Monitored Devices in the NetOps Portal user interface).  

Examples:

All Devices shows a count of (0)

When looking at a device with thousands of interfaces, the interfaces are not displayed

Environment

Performance Management, all supported versions

Cause

The rest call made to retrieve the list of interfaces is to large for the system to handle.  Here is an example of the Warning seen in the Data Aggregator's karaf.log:

 

WARN | ########-####### | YYYY-MM-DD HH:MM:SS,#### | WebApplicationExceptionMapper | pl.WebApplicationExceptionMapper 73 | xf.cxf-rt-frontend-jaxrs | | javax.ws.rs.WebApplicationException: java.lang.IllegalArgumentException: The estimated count of <number over 200000> for endpoint ports exceeds the maximum allowed by the manager of 200000. To avoid risking the integrity of the server, we are unable to return the request XML. 

Resolution

1. Create a file named com.ca.im.item.ws.impl.AutomaticWebServiceManagerImpl.cfg in the DA's INSTALL_ROOT/apache-karaf/etc/ directory. 
2. Add the following line to that file:   maxReturnItemCount=<number>
3. Now update the interface list for the device in question, on the DA
   • Go to Administration > Monitored Devices
   • Find the device in question
   • Under the "Polled Metric Families" tab click next to the "interfaces" metric
   • Interfaces should not appear in the bottom "Interface Components" pane

Additional Information

The exact <number> that you put in should mimic the approximate count seen in the DA karaf.log with a little headroom. Setting this to a high number can result in OutOfMemory errors.
