System Monitoring Various Tandem software products help you monitor the TRANSFER delivery system.
Tasks are routinely performed by various individuals at each node in the network. A
system administrator monitors sessions currently in progress through the ADMIN
application. A system operator takes TMF online dumps of the TRANSFER database
files. A system manager monitors the overall activity within the TRANSFER
environment.
The following paragraphs provide a brief overview of the software products that you
can use to monitor TRANSFER operations. You can find detailed information in the
related manuals for these products.
PATHWAY Environment PATHCOM, the PATHWAY command interface to PATHMON, allows you to
monitor activity in the TRANSFER PATHWAY system, to stop terminals and
processes if problems arise, to perform online load balancing, and to make
configuration changes.
Network Environment Tandem offers several software products that help you monitor your network:
The Communications Utility Program (CUP)
The Communications Management Interface (CMI)
The Subsystem Control Facility (SCF)
With these tools, you can add and delete terminals as requirements change, monitor
activity on communication lines, and diagnose problems on communication lines. You
can monitor network lines as well as lines connecting terminals to your NonStop
system.
In addition, the NETMON network utility program lets you monitor traffic throughout
the network and identify problems on network lines. If traffic is too heavy on a
particular line or through a particular node, you can change the weighting factors used
to select paths between nodes.
System Performance MEASURE, a performance measurement tool, lets you measure CPU and disk activity
throughout the system. If traffic is uneven or too heavy, you might want to move
devices or processes from one processor to another processor or move files from one
disk to another disk.
