Issue/Introduction

When viewing the Self Monitoring Dashboards in Dx NetOps Performance Management,  Dx NetOps Portal web UI all Views return a message "No Data Available".

The DataAggregator:<IP> default Data Aggregator (DA) Device element is not found in the Inventory->All Items->'System Health - Data Aggregator' group.

Environment

All supported Dx NetOps Performance Management releases

Cause

Out of the box a default Data Aggregator (DA) Device element is created in the Dx NetOps Performance Management environment. This is used to provide Self Monitoring data for the environment in default Dashboards.

The product also allows an SNMP agent on the DA to be discovered and managed as a standard SNMP managed Device element.

The product reconciles the two Device elements based on IP and Device Type details. It results in a single Device element to use for both SNMP managed Server data, and Self Monitoring data for the Dx NetOps Performance Management environment. The SNMP managed Device element gets set with two Device Type values 'Data Aggregator, Server'.

A Dx Netops Mediation Manager (CAMM)  Device Pack (DP) is integrated with the Dx NetOps Performance Management environment. This DP creates a Device element representing the DA using the servers IP address as both a Device name, and as an IP Address in the IP Address field. This Device element has a Device Type set to 'EMS Device'.

Due to the Dx Netops Mediation Manager (CAMM) Device element using the same IP as the default DA Device element, but having an unexpected 'EMS Device' Device Type set, this broke the products reconciliation code. The result was the Dx NetOps Portal system selecting the Dx Netops Mediation Manager (CAMM) Device element when Self Monitoring data was requested. Because the data is not tied to that Device element, it returned 'No Data Available'.

Resolution

There are two methods to resolving this.

1: If the Dx Netops Mediation Manager(CAMM) DP should not be creating Device elements representing the DA server, delete the elements and edit the Dx Netops Mediation Manager(CAMM) DP to ensure the DA is not created as an element.

2: If the Dx Netops Mediation Manager(CAMM) DP should be creating Device elements representing the DA server, configure them to set the IP Address to a blank/empty value.
