Frequency Distribution
Frequency Distribution
When you specify the FREQTABLE option of the STATS SERVER command, the
PATHMON process displays supplemental statistics on the completion of SCREEN
COBOL SEND statements within a given time interval. These statistics are collected
only if your environment includes the Pathway/iTS product.
The supplemental information is contained in the frequency distribution table, as shown
in Example 7-5. A separate frequency distribution table is generated for each server
class.
Table 7-4 on page 7-8 shows the server statistics for frequency distribution and what
they indicate.
