| start_time | datetime | The time when the agent began processing the article. |
| duration | int | The length of time that the agent processed an article, in seconds. |
| inserts | int | The number of inserts that have been applied to a specific article during synchronization. This value will increment during the synchronization process, and the ending value represents the total number. |
