Frequency Distribution
Frequency Distribution
When you specify the FREQTABLE option of the STATS TERM command, the
PATHMON process displays supplemental statistics on response time within a given
time interval.
The supplemental information is contained in the frequency distribution table, as shown
in Example 5-9. A separate frequency distribution table is generated for each terminal.
The TCP does not generate values for these fields: REPLY REQ CNT, REPLY I/O
CNT, CHECKPOINT REQ CNT, CHECKPOINT I/O CNT, and DATA AVG SIZE.
Use the frequency distribution table to determine the number of transactions in
progress. Knowing the number of transactions enables you to identify the number of
links required, and thus the configuration you need.
The Table 5-7 on page 5-26 lists the terminal statistics for frequency distribution shown
in Example 5-9 on page 5-25.
