# Skill Monitor overview

> The Overview section of Skill Monitor shows per-skill stats — queue, throughput, manual review time, STP rate, accuracy, and total transactions.

The **Overview** section displays per-skill statistics across the [transactions](/vantage/documentation/runtime/skill-monitor/transactions) processed by ABBYY Vantage.

## Statistics columns

* **Queue / Throughput** — number of transactions awaiting processing and the number processed by the skill in the last hour.
* **Estimated Manual Review Time** — estimated time operators need to manually review the documents (for skills with the Manual Review stage enabled).
* **Quality STP Rate** — percentage of documents the system processed automatically without sending them to manual review (for Process skills with the Manual Review stage enabled).
* **Accuracy** — the learning accuracy for Document skills and Classification skills.
* **Processed Transactions** — total number of completed transactions processed by the skill.

<Info>
  If Queue shows a high number while Throughput stays low — for example, Queue is 300 and Throughput is 0 — transactions are held up at one of the processing steps. The system administrator needs to investigate.

### What creates a transaction

A transaction is a unit for processing documents and document groups in Vantage. The following actions create a transaction:

* Uploading documents on the **Documents** page.
* Uploading documents from a mobile device.
* Uploading documents using **Try Skill**.
* Creating a transaction via the Vantage API.
* Uploading documents from third-party systems using connectors.
* Uploading documents from an additional source set up in the **Input** activity block of a Process skill (an email folder or a shared folder).
* Uploading documents in Skill Designer.

## Finding and filtering skills

Use the **Find name** button to search for skills. You can also sort skills by type using the filter at the top of the page.

## Using these statistics

Administrators and supervisors use these statistics to optimize system operation. For example:

* A process owner can check the **Throughput** column to see whether the number of processed transactions meets the KPIs.
* A processing supervisor can compare the **Queue** and **Throughput** columns to see whether transactions get stuck at certain stages.
* A manual review supervisor can check the **Estimated Manual Review Time** column to see whether more operators should be allocated to a particular skill.

To view document processing statistics for a specific skill, click its name in the table or open the [Transactions section](/vantage/documentation/runtime/skill-monitor/transactions) using the bookmarks at the top of the screen.
