Metadata Events

The metadata module emits the following events and telemetry information.

Counters​

Stored Objects​

This counter is used to get counts of things stored on the chain.

When this module writes a new object to the chain, this counter is incremented by 1. When this module deletes an object from the chain, this counter is decremented by 1. When this module updates an object on the chain, this counter is not updated.

Stored Object: Keys​

"metadata", "stored-object"

Stored Object: Labels​

"category", "object-type"

Stored Object: Label: Category​

This label groups the objects into a general type.

The string for this label is "category".

Possible values:

  • "entry"
