Maximum message length

This value is the maximum message length that the OS agent can receive without truncating the message.

The maximum message length is different for Performance Management and Tivoli® Netcool/OMNIbus.

Performance Management
For events sent to Performance Management, the msg attribute is limited to 2048 bytes. Messages that are greater in length are truncated.
Tivoli Netcool/OMNIbus
For events sent through the Probe for Tivoli EIF to Netcool/OMNIbus, the total size of the event, including the class name and all slots and their values cannot exceed 4096 bytes. For example, in the following sample EIF event, ;END does not count against the 4096-byte limit. However, everything else does count against the limit, including the syntactic elements such as the semicolons, quotation marks, and equal signs.
