Issue/Introduction

Trying to capture DisplayString data via SNMP for inclusion in Table Views as a column. 

The OID targeted is defined with a value of "SYNTAX DisplayString (0 .. 255)".

In this situation this OID represents the IP address for the device. It is static and will not change post Discovery. It doesn't need to be polled.

How can we capture this value, and display it in CA Performance Center (CAPC) in a Table Column along side other metrics for the device?

Environment

All supported releases of CA Performance Management

Resolution

You can add it into a Certification as a new Metric, but there is no way to add it to any View or Report in CAPC. 

We only allow selection of Polled Metrics in Views and Reports, nothing can be added that comes from a DisplayString such as Name, Description, etc. We do allow some other fields, specifically on interfaces but that is the limit.

What if it was polled and had the same value all the time?
We only support metrics that are numbers to be polled. Since it's not a number, we can't poll it.

This is hard coded there is no custom/automatic adding of fields.

OpenAPI would not have access to the new metric field either.

We do have custom attributes on devices and interfaces that can be created. Need to use REST to set these values on the items in the Data Aggregator (DA). That info is synced to CAPC and can be added to Views and Reports.
