Getting Started After Deploying Prometheus¶

Service management is performed in the Prometheus web interface, the link to which is located in Invapi. Authentication credentials, which can be found either in the Information >> Tags section of the server control panel or in the email sent to you:

• Link: in the webpanel tag;
• Login and Password for server management: arrive in an email to your inbox when the server is ready after deployment.

Prometheus Dashboard¶

The Prometheus dashboard provides an intuitive user interface with numerous functional elements for effective monitoring and analysis of metric data. On this page, you'll find a menu for navigating key sections, settings for personalizing the interface, a field for entering metric data queries, and panels for displaying query results as tables or graphs.

Main Interface Elements:

• Query String: A field labeled Enter expression (press Shift+Enter for newlines) for entering PromQL queries. To the right is a button Execute to execute the query.
• Menu:
  • Alerts: section for viewing current alerts.
  • Status: Displays the status of the monitoring system.

The Expression (press Shift+Enter for newlines) string - a field for entering metric data queries, allows for multi-line queries and their execution by pressing the Execute button.

The Table and Graph options allow you to choose the way query results are displayed: as a table (Table) or graph (Graph).
