Subj: IBMCON DN6x statistics logger for TOPS20 Rel 4
.subtitle Subj: IBMCON DN6x statisics logger for TOPS20 Rel 4
.fill
.para
The DN64 software available with TOPS20 Release 3A automatically
made entries in the system log file, ERROR.SYS providing notification
of the enabling and disabling of lines and periodic statistics reports.
In release 4 of TOPS20 the DN6x software has been integrated into
Galaxy, but the code to enter statistics into the system error
file was not included. The program IBMCON provides this service
in release 4 of TOPS20 for both the KS and KL processors.
.subttl USING IBMCON
.page
.CENTER
USING IBMCON
.para
IBMCON obtains the status of the front end solely by use of the monitor
interface to the DTE. Since IBMCON does not rely on other DN6x
components running in the mainframe it must periodically examine
or poll the front end to collect statistics and determine status
changes. This polling can affect performance. Only run IBMCON periodically
when you need to collect statistics or when the hardware is suspect.
.para
To run IBMCON you must be an enabled user with wheel or operator
capabilities. If you are not enabled or you do not have wheel
or operator capabilities, the enable command will always report
that the front end is not running. IBMCON provides command recognition
and prompting and defaults most arguments. The minimum interaction
necessary to begin data gathering is the enable command and port number.

COMMANDS
.skip 1
DISABLE (polling on port) port number
.skip 1
.para
The DISABLE command stops IBMCON from polling the specified port,
thus stopping all data gathering for all lines on that port.
The port number must be specified, it has no default. When IBMCON
is run on a KS processor, the port number is restricted to 10 or 11.
Ports 10 and 11 refer to the DN22 running on synchronous lines
KDP__0__0 and KDP__0__1 respectively. When running on a KL, the port
number is restricted to the range 11-13. Ports 11-13 refer to the
DN20 running on DTE'2 1-3 respectively.
.skip 1
.no fill
ENABLE (polling on port) port number (interval) minutes between polling
.fill
.skip 1
.para
The ENABLE command starts polling on the specified port for the
specified interval. After each interval has passed, IBMCON examines
all lines on the front end associated with the specified port to
determine if they have become active (the node to which they
connect has become enabled) or inactive (the node to which they
connect has become disabled). When a line becomes active or inactive
an entry is made in ERROR.SYS. Statistics entries are made in ERROR.SYS
for all active lines. The default polling interval is 10 minutes.
Note that when IBMCON is started it will make
a NODE HAS ENABLED entry even if the node had been up for some time.
Also note that the timestamp for the NODE ENABLED or DISABLED entries
reflects the time that IBMCON first saw the node active, not the exact
time at which the node was enabled.
.skip 1
EXIT
.skip 1
.para
The EXIT command causes IBMCON to exit to EXEC command level.
.skip 1
SET (logging interval on line) line number (port) port number
.break
.indent 5
(interval) minutes between logging
.skip 1
.para
The SET command changes the default logging interval on a line by line
basis. The logging interval is the time between statistics entries
for all active lines on enabled ports.
The default logging interval is 60 minutes. Note that this command
must be entered separately for each line which is to have a logging
interval different from the default.
.skip 1
WAIT (forever)
.skip 1
.para
The wait command causes IBMCON to run without an outstanding
input wait for commands. Following the wait command, no prompt
is issued and no command will be processed. The WAIT command
allows the user to run IBMCON in batch.

ERROR MESSAGES
.para
PORT port number IS NOT ENABLED
.PARA
An attempt was made to disable a port which was not enabled.
.para
PORT port number IS ALREADY ENABLED
.para
An attempt was made to enable a port which was already enabled.
.para
MORE LINES actual number of lines ON PORT THAN ALLOWED max number
.para
More lines were found on the enabled port than are allowed for by
IBMCON. IBMCON will truncate the number of lines watched to its
own maximum number (6).
.para
PORT port number NOT RUNNING
.para
This error message is printed whenever IBMCON cannot determine the
status of the front end. It is printed if the port is not running
or if the user is not an enabled wheel or operator.

The JSYS failed which enters entries into the system error file,

The line status string is returned as an 8 bit byte string packed 4 bytes left
justified in a 36 bit word. In each byte the bit numbering is bit 0 to
the right (LSB) and bit 7 to the left (MSB).
Any 16 bit values have the 8 bit bytes that make it up swapped. So before
these bits defined below are valid, the bytes have to be swapped back again.

Following the installation procedures described in the IBM
Emulation/Termination manual (AA-5095B-TM) is sufficient
for installing IBMCON. IBMCON requires no setup procedure
or data files; only the executable file IBMCON.EXE is required.
.para
Rebuilding IBMCON requires that the following files from the
Galaxy distribution tape can be found in the DSK: search path.
The versions of the files from the Galaxy tape used to build
IBMCON must correspond to the versions of the files used to build
the Galaxy which runs on the same system as IBMCON.
