What is Petals View?

Petals View is a webapplication dedicated to Petals ESB flows monitoring.

Installation in a nutshell

• download these components: petals-se-notification.zip & petals-se-kpi.zi;
• download petals view's war (petalsview.war);
• create all sa-kpi you need to get the infos you want (with prior installation and configuration of related components and services assemblies).

How does it work?

• You configure a component so that when it is installed, it will register in petals-se-notification base: "I will send notifications to you".
• Upon reception, petals-se-notification forwards these notifications to petals-se-kpi (configured with its own services assemblies – sa-kpi).
• What is a sa-kpi? It's a set of filters that will select specific information among the whole flow data. Whenever a notification fits with a sa-kpi, this notification (with selected data only) will be saved in a relational database. This database has to be shared between KPI Service Engine and Petals View.
• Petals View then connects to this database to retrieve informations.
• Messages are saved into the database in a "raw" format. Petals View will give them meaning by naming and organizing them in a human-readable way.
