Preventing Unnecessary Enlargement of Statistics Files

The Message Statistics facility counts messages and commands by message or command ID. The first word of the message or command is the message or command ID.

To prevent the Statistics files from becoming too large and to eliminate duplicate information, it may be appropriate to group messages or commands according to other criteria. It is useful, for example, to group messages or commands under one message or command ID when:

Messages start with free text. Accumulating each of these messages under a different message ID enlarges the size of the Statistics file, and may prevent the accumulation of meaningful statistics for the message.

Concatenation of JES2 commands with different operands results in separate statistics accumulation for each operand. For example, statistics for $PJ05555 and $PJ01234 are normally accumulated under different IDs even though both IDs refer to the same command.

Separate statistics are accumulated for messages that are not of interest to the user.

AutoEdit reserved variable %%$STATID can be used to specify the ID under which the messages or commands are accumulated. For example

ON COMMAND $P*

DO SET %%$STATID=$P

Rule table STATS from the RULES library has been provided to perform the necessary grouping by %%$STATID. This table can be adapted and used according to site requirements.
