Channel Path Activity Report
The CHANNEL control statement produces the Channel Path Activity Report. The header of this report shows the date and time the data was collected and the interval between snapshots. Each row in this report reflects the activity of a single channel path. This report is sorted by default in order of increasing channel path ID.
The following figure is an example of the Channel Path Activity Report.

The following table lists the header, ID (used when specifying keywords), and a brief description of each column in this report.
Column descriptions for the Channel Path Activity Report
Column header | Column ID | Description |
|---|---|---|
ID | CHPID | hexadecimal number representing the channel path. |
CHANNEL NO | GNO | for each channel type which is managed by DCM (Dynamic CHPID Management) a summary line showing the average values for all channels in this group The number of channels of the group is given in column NO. |
CHANNEL G | CHGEN | indicates the generation (G) and is used to differentiate between channels of the same channel type, when one has significant differences from the other |
CHAN TYPE | TYPE | channel path type |
SHR | SHR | indicates whether the channel path is shared between LPARs |
PART BUSY | PARTBUSY | percentage of time that a shared channel path was busy on the home partition |
TOT BUSY | TOTBUSY | channel path utilization percentage for the entire system |
BUS BUSY | BUSBUSY | percentage of the cycles per second used for I/O operations over the maximum internal bus cycles per second |
PART READ | PARTREAD | rate per second of megabytes read using the channel for the partition |
TOT READ | TOTREAD | rate per second of megabytes read using the channel for the complex |
PART WRITE | PARTWRITE | rate per second of megabytes written using the channel for the partition |
TOT WRITE | TOTWRITE | rate per second of megabytes written using the channel for the complex |
PART B/SEC | MSGPBYT | rate of messages sent by programs (in bytes) for the partition |
TOTAL B/SEC | MSGTBYT | rate of messages sent by programs (in bytes) for the entire complex |
PART M/SEC | MSGPRTE | rate of messages sent by programs for the partition |
TOTAL M/SEC | MSGTRTE | rate of messages sent by programs for the entire complex |
PART M-SIZE | MSGPSZE | average size of messages sent for the partition |
