Incomplete event data from a situation is forwarded to Tivoli Enterprise Portal Server

Context:

The typical situation for monitoring agents in IBM® Tivoli® Monitoring targets a specific resource and generates a limited amount of monitoring data. In some cases, a OMEGAMON® for Storage on z/OS® situation can generate larger amounts of information.

For example, a situation might generate a large amount of information if it monitors multiple sub-objects on a managed system, such as a situation that monitors multiple channels. As a result, relatively large amounts of monitoring data might be generated every time that the thresholds of the situation are triggered.

Limitation:

When TEC integration is enabled for the OMEGAMON for Storage on z/OS, the Tivoli Enterprise Portal Server receives a buffer of monitoring data that cannot exceed 4K bytes in size. In most cases, this buffer size is sufficient. However, some situations in OMEGAMON for Storage on z/OS can generate more than 4K bytes of data. When the data generated for the situation exceeds this limit, the excess data is truncated and is not presented at the Tivoli Enterprise Portal Server.

Workaround:

None. For situations that can generate large amounts of data, be aware that Tivoli Enterprise Portal Server is retrieving only the first 4K bytes of data.
