NPM Network Collection Function
The NPM network collection function records volume, performance, and reliability data as collected in the Network Control Program (NCP), which is the communication controller's operating system.

The NPM network collection function records volume, performance, and reliability data as collected in the Network Control Program (NCP), which is the communication controller's operating system.
NPM communicates with the Network Performance Analysis Logical Unit (NPALU) in the NCP to retrieve data that can then be recorded in its review file, the network log, and/or SMF (or the VM equivalent). The
MICS Network Analyzer
is designed to process the SMF type 28 record, or the VM equivalent for NPM.The NPM Network Subsystem produces many subtypes of the SMF type 28 record. Of these subtypes,
MICS
processes only those that are Interval or Monitor Event Records. Specifically, these are subtypes '10'X, '11'X, '12'X', '13'X, '18'X, '19'X, '70'X, '71'X, '74'X, '75'X, '77'X, 'A0'X, 'A1'X, 'D6'X, 'D7'X, and 'DC'X.Interval Record
The SMF type 28 record (subtypes '10'X, '11'X, '12'X, '13'X, '70'X, '71'X, '74'X, '75'X, '77'X 'A0'X, 'A1'X, 'D6'X, 'D7'X, and 'DC'X) contains load, performance, and reliability data collected within the user-defined time interval that is specified in the INTERVAL operand of the NPM command. At interval expiration, NPM requests data from the communication controller, which it assembles and records to SMF. More frequent collection results in more precise data, but at a higher processing cost for both the network and the
MICS Network Analyzer
.Monitor Event/Exception Record/Resolution Record
NPM is capable of recording exception conditions that are recognized by the NCP. Exceptions are recorded in the SMF type 28 subtype '18'X and resolutions in SMF 28 subtype '19'X records.
Note that you must provide an archive file that contains SMF type 28 records for DAILY processing by the
MICS Network Analyzer
