Displaying Statistics
STATUS PATHMON Command
The STATUS PATHMON command displays status information for all PATHMON
processes in the Pathway/XM environment. For each PATHMON process, the display
includes the PATHMON process name, the state (open or closed) of the PATHCTL and
log files, and a list of the processes (such as LINKMON processes, TCPs, and
PXMCOM processes) currently communicating with this PATHMON process.
You specify this command as follows:
>> STATUS PATHMON
For the syntax of the STATUS PATHMON command, refer to STATUS PATHMON
on page 11-76.
Displaying Statistics
The STATS command displays current statistical information about an object in the
Pathway/XM environment. The only global Pathway/XM object for which statistics are
displayed is the NODE object.
STATS NODE Command
The STATS NODE command displays statistics about the usage of the resources
represented by the NODE object. You can display statistics for a single NODE object or
for all NODE objects in the Pathway/XM environment.
This command displays the following information for a NODE object:
•
For each CPU, the maximum and current number of process reservations (including
reservations for all types of processes, not just distributed server processes)
•
The percentage of reservation requests denied and reservation extension requests
The following example displays statistics for a NODE object named CLIENT1:
>> STATS NODE CLIENT1
To set all statistics counters to zero for this NODE object, you can issue the following
command:
>> STATS NODE CLIENT1 RESET
The statistics for NODE objects are always available. Statistics collection for NODE
objects cannot be turned on or off by SET commands in the PXMCFG command file.
For the syntax of the STATS NODE command, refer to STATS NODE on page 11-64.
Migrating Configurations Online
As your business needs change, requirements for your transaction processing
configuration are likely to change. At any time, while your Pathway/XM environment is
running, you can create a new SuperCTL file, adding, deleting and modifying objects, as
needed. Then you direct Pathway/XM to generate a plan for migrating from your
