The "type" of information managed by CEMon is defined by plugins (also known as sensors) that can be plugged into the CEMon core engine.

Each plugin is basically responsible to deal with a specific "type" of information.

For each plugin (identified by a topic name), one or more dialects (representing how the relevant information is rendered) are available.

Existing CEMon sensors are:

• CE_MONITOR. Returns CE information, according to the Glue Schema.
• OSG_CE Returns CE information, according to the Glue Schema, suitable for OSG needs.
• GridICE Returns GridICE information
• CREAM job Returns CREAM job state information

By implementing specific sensors, the CEMon service can also be configured to collect and provide other information types.

It is possible to interact with the CEMon service in a synchronous way (i.e. the client queries the CEMon service to get the required info) or asynchronously (i.e. the client can subscribe to get asynchronous notifications coming from the CEMon service). Moreover the CEMon administrator can configure predefined subscriptions, so the specified clients are automatically notified with asynchronous events, without the need of an explicit subscription.

Specific policies and specific actions can be set on CEMon subscriptions. For example if is possible to define a subscriptions so that the client is notified only when certain conditions are satisfied.
