This is a glossary of terms related to Percona Cloud Tools (PCT).

API key

A unique key used by Percona Agent to identify the data it collects as belonging to the corresponding organization. If you have a PCT Account, you can find the API key at https://cloud.percona.com/api-key

Note

Make sure that the correct organization is selected.

Metrics Monitor

A tool used for presenting collected MySQL and system metrics on time-based charts.

For more information, see the Metrics Monitor section.

organization

An entity in PCT that defines all infrustructure components and people involved. When you sign up for a PCT Account, a default organization is created. You can add other users to the organization, create other organizations, or be added to existing organizations.

Each organization is assigned a unique API key, which is used by Percona Agent to identify the data it collects. During installation, Percona Agent adds corresponding server and MySQL instances to the organization.

PCT Account

A user account on cloud.percona.com.

For more information, see the PCT Account section.

Percona Agent

A service that runs on the server, collects data about perfomance and MySQL metrics, and sends it to PCT.

For more information, see the Percona Agent section.

Percona Toolkit
A collection of advanced command-line tools to perform a variety of MySQL and system tasks. The toolkit is used by Percona Agent to generate System Info reports.
Performance Schema

An alternative source of query data to the slow query log. Performance Schema is available starting from MySQL 5.6, and is enabled by default starting from MySQL 5.6.6. Data is collected from the performance_schema.events_statements_summary_by_digest table, and is used by the Query Analytics tool.

For more information, see Performance Schema.

Query Analytics

A tool used for analyzing the history of MySQL queries. Data is collected either using the slow query log or Performance Schema.

For more information, see the Query Analytics section.

slow query log

The default source of query data for Query Analytics. Slow query log is available starting from MySQL 5.1, and provides a wealth of valuable data for deep analysis.

A faster and more efficient way (but without as much data) is the Performance Schema.

System Info

A tool for viewing the status and configuration of the server and MySQL instances. It uses tools from Percona Toolkit to generate the report.

For more information, see System Info.
