Command Reference

Command Reference

DL Command

DL Command

Displays monitoring statistics for a PowerExchange Logger for Linux, UNIX, and Windows process and its tasks.
The command writes the following statistics to the PowerExchange message log file and displays the statistics on screen:
  • The PowerExchange Logger process ID
  • The status of the PowerExchange Logger Writer subtask at the time the command is issued
  • The CPU time used by the PowerExchange Logger since it started
  • PowerExchange Logger memory use by the Controller, Command Handler, and Writer tasks. For the tasks, memory use is reported in the following categories:
    • Current. The amount of memory that the task is currently using.
    • Total. The amount of memory in use by the task plus related header overhead. This value fluctuates as memory is dynamically allocated and freed during PowerExchange Logger processing
    • Maximum. The largest amount of memory that has been recorded for the "Total" category up to the point in time when the monitoring statistics are generated.
  • Counts of inserts, updates, deletes, and commits that the PowerExchange Logger has processed, total and for the open Logger log file and the active logging cycle
Before you run the command, you must configure the STATS=(MONITOR) parameter in the PowerExchange Logger pwxccl.cfg configuration file on the system where the PowerExchange Logger runs to enable collection of the monitoring statistics. In this statement, you can optionally include the
interval
positional parameter to print these statistics at a specific interval, in addition to printing them on demand.
Fewer interval-based monitoring statistics are displayed on screen than are printed to the PowerExchange message log to avoid flooding the screen with output over time.

Syntax

Use the following syntax to issue the command from the command line against a PowerExchange Logger process that is running in foreground mode:
DL
Alternatively, you can use the equivalent DS command:
DS
If you run the PowerExchange Logger in background mode, you must use the pwxcmd program to issue the displaystats -tp logger command.

Example Output

The following example command output shows the monitoring statistics for a PowerExchange Logger process and its tasks:
PWX-26011 Command handler received command "DS" PWX-00723 Command <display L stats> succeeded PWX-37130 PWXCCL pid = 7144 Writer status = Reading or waiting for source data PWX-37134 CPU Time = 0:00:02.589616 PWX-37131 Memory (Current/Total/Maximum) PWX-37132 Controller: (981/983/1849) KB Command Handler: (0/0/34) KB Writer: (5127/5147/5181) KB PWX-37135 Status 7144 Totals I=000000024344 U=000000000000 D=000000024336 C=000000004004 Total=000000052684 PWX-37136 CurrFileOpened : 2015-08-11 13:20:39 I=000000024344 U=000000000000 D=000000024336 C=000000004004 Total=000000052684 PWX-37137 Active Cycle : 2015-08-11 13:21:01 I=000000024344 U=000000000000 D=000000024336 C=000000004004 Total=000000052684
This report contains the following fields:
  • PWXCCL pid. The process ID of the PowerExchange Logger process.
  • Writer status. The status of the PowerExchange Logger Writer subtask at the time the command was issued.
  • CPU Time. The amount of CPU time used by the PowerExchange Logger since it started.
  • Controller. The amount of memory in kilobytes that the PowerExchange Logger Controller has used.
  • Command Handler. The amount of memory in kilobytes that the PowerExchange Logger Command Handler has used.
  • Writer. The amount of memory in kilobytes that the PowerExchange Logger Writer subtask has used.
  • Status. The process ID of the PowerExchange Logger process.
  • I, U, D, C, and Total. Counts of inserts, updates, deletes, and commits that the PowerExchange processed, with the total for all of these operation types. These values are reported for the PowerExchange Logger process, the currently open log file, and the active logging cycle.
  • CurrentFileOpened. The timestamp that indicates when the log file was opened.
  • Active Cycle. The timestamp that indicates when the active logging cycle started.
