The manager writes status information to Server Status Streams, which are special Sybase CEP streams that transmit messages with various server events and metrics.
Every message appears as a row in a Server Status Stream and contains the following information:
SourceTimestamp: The message timestamp.
MessageGroup: The group to which the message belongs.
ObjectID: The object identifier for the group.
The code to listen to the status stream and act upon the events is called a "plugin", and it runs as part of the server process.
There are two groups of status events: container events that apply to the container server and manager events that apply to the manager server. Examples of status events include CclApplicationInfo Status messages, CclQueryInfo Status messages, ContainerInfo Status messages, and ManagerInfo Status messages.
