Issue/Introduction

Hi,

Using PM 3.7.16 and CAMM 3.7

I'm creating a custom device pack to address some PM limitations with utilization calculations.

The device pack generates CAMMXML data that seems valid.

I have a custom vendor cert and metric family to receive the data, this also imports successfully.

CAMM Inventory is created successfully.

Note that the target devices are SNMP devices that are polled via SNMP on datacollector 1 (domain "A") and receive CAMM items on datacollector 2 (same domain "A").

When performance metrics are generated by CAMM and read by DC, I see error messages in Expression.log about missing attribute, however this attribute is populated for all records.

The result, is that I'm getting new records in vertica for the expected items, for each timestamp pushed by CAMM, but all metric values as blank.

 

I'll attach the files for CAMM output (inventory and perf), DA VC, MF and component definition, and DC log.

Cause

The tags are case sensitive

The CAMM XML produced <Data-Speed> tags instead of <DATA-Speed>

Environment

Release : 3.7

Component : CA MEDIATION MANAGER

Resolution

Recreated with <DATA-Speed>
