Viewing Error Messages with Text Console in
Crestron Toolbox
The persistent log (PLOG) is a log of error messages that are identified by the
control system. The latest PLOG can be viewed in the Text Console in Crestron
Toollbox and are available after a control system reboot. The control system, or
attached device, may have a MSG LED that indicates an error has occurred.
The control system stores current log files at “\SYS\PLOG\CurrentBoot”. The
current log file is locked and cannot be opened for transfer.
To view the contents of the current PLOG enter ERR PLOGCURRENT into the text
console in Crestron Toolbox.
The control system checks for new error messages every 2 minutes and commits any
messages to a log file for viewing. The control system creates up to 9 temporary log
files (“Crestron_01.log” to “Crestron_09.log”) and one permanent initial log file
(“Crestron_00.log”). Log files have a 256 kB maximum size for each file—when the
size limit is reached the next log file is created. Log files continue to be created until
all 10 files are full.
After all 10 log files are created and the 10
th
log file reached its 256 kB maximum
size the control system overwrites the first temporary log file (“Crestron_01.log”)
and begins logging until it is full. The control system then overwrites the second
temporary log file (“Crestron_02.log”). This operation repeats as long as there
continue to be errors.
If a soft reboot is performed any pending messages are written to the latest log file
and zipped into one file. On reboot the zipped file at “\SYS\PLOG\CurrentBoot” is
moved to “\SYS\PLOG\PreviousBoot”. During subsequent reboots the zipped file
from “\SYS\PLOG\PreviousBoot” is moved to “\SYS\PLOG\ZippedLogs” for future
storage.
The amount of space reserved for current and zipped log files is 50 MB. If the
control system runs out of space for log files it deletes the oldest log file. The control
system also has a maximum of 50 log files and deletes the oldest log file once the
maximum has been reached.
The control system continues logging errors as long as there are not over 250
messages per 2 minute period for two consecutive 2 minute logging periods. For
each error period the text console results displays PersistentLog: Error
state threshold met if error logging is suspended. When logging is
suspended the log file displays PersistentLog: Consecutive error
states detected; logging is suspended. The user also receives a
PersistentLog is suspended, please contact dealer. message
in the text console.
Message logging is resumed when there has been less than 10 error messages logged
for 10 consecutive 2 minute logging periods. When logging is resumed all messages
from the 10 consecutive 2 minute logging periods are logged to the log file. The log
in text console displays PersistentLog: Consecutive quite states
detected; logging is resumed.
An example of a PLOG result is shown below:
