Often times systems use the tag name "description" as part of the alarm payload. However, description is a reserved word, and its use or access is limited by the system.
Here are a few examples of how not to use tag name "description":
Use the tag as a primary or secondary property
Use the tag as part of the maintenance plan BPQL
Use the tag as part of a correlation pattern
We recommend users to create an additional tag (i.e. "short_description") that contains the value of description for use in the BigPanda system.
However, you are able to leverage the "description" field to create Alert Enrichment Rules (i.e extraction rules).
