Usage metrics
Learn about the main usage metrics that impact Camunda 8 pricing.
Definition of metrics
There are four main usage metrics that have an impact on Camunda 8 pricing. The specific metrics that apply to billing may vary depending on your contractual agreement with Camunda.
It is important to understand these definitions, their impact on billing, and how to retrieve them.
Root process instance
The number of root process instance executions started. This is also known as process instances (PI). A root process instance has no parent process instance, i.e. it is a top-level execution.
Decision instance
The number of evaluated decision instances (DI). A decision instance is a DMN decision table or a DMN literal expression. In a Decision Requirements Diagram (DRD) each evaluated decision table or expression is counted separately.
Task user
The number of task users (TU) that have served as assignees.
Tenant
A tenant is a logically isolated space within a shared Camunda 8 installation, with its own data, configurations, and user permissions. Usage metrics can report how many tenants were active in a period and, when available, a per-tenant breakdown of process, decision, and task-user usage.
Retrieve metrics in SaaS
In Camunda 8 SaaS an Owner or Admin of an organization can retrieve the information from the Billing page.
You can access the Billing page by selecting Organization Management in the Camunda Console navigation bar.
Retrieve metrics on Self-Managed
