Max Msgs          (Queues)

DESCRIPTION
The "Max Msgs" column represents the maximum number of "Messages" that have been
recorded on a particular system queue since Sun MTPScan initiation (not Sun MTP). A 
queue is an operating system resource enabling interprocess communication. 
Messages are posted on the queue by one process for retrieval by another process.


VALUES
The value of "Max Msgs" is a numeric quantity obtained by comparing the current
value to the number of "Messages" and setting "Max Msgs" to be the maximum of 
the two.


INTERPRETATION
This value indicates the queue usage (along with "Max Bytes") at peak loads in 
production processing. Note that the actual peak usage of a queue may occur 
between Update Intervals and may escape Sun MTPScan's inquiries to the operating
system.


CONCLUSIONS
Most systems have a kernel parameter that specifies the maximum number of
messages that can be on a queue at any given time. This parameter is similar
to the "Capacity" of a queue (which is measured in bytes). Consult the System   
Administrator's Guide to find out where to look for this value on the your 
system. If "Max Msgs" approaches this value, it must be increased to obtain
better performance from the Sun MTP system.

Also note that the size of the messages being put on the queue can also affect
the maximum number of messages allowed on a queue, because of a queue's 
"Capacity". For example, consider a queue that has a "Capacity" of 100 bytes and
a maximum of 10 messages. If the messages for this queue are 50 bytes each, the
queue has an effective limit of 2 messages.
