LOGS Reference
LOGGING
JANOS creates a number of log files. These are text files where generally a
single line represents some event. Each entry has a timestamp to the
millisecond shown in the local timezone. The (Java date) format is as
follows:
MM/DD/yy HH:mm:ss.SSS, message...
05/28/21 09:25:52.000, Clock synchronized via NTP (+6)
System log files are located in the root of the File System and are
limited in size. When a log file reaches approximately 64KB in size
it is aged. The .LOG file is then saved as a .LOG.BAK file overwriting
any previous backup and a new .LOG file is started. A SYSLOG Server may
be optionally defined which will receive notice of logged events.
/jniorsys.log
This is the main system log containing general log notices. Entries appear
here when the unit boots, processes are started, Registry keys are altered,
etc. Any issues with the system will be reported here.
/jniorboot.log
This is a record of the most recent boot. This includes diagnostic reports.
Any issue in start-up will be reported in this log. Unlike other log files
this file contains only the most recent start-up detail. On the next boot
the content is appended to the associated .LOG.BAK file which remains
constrained to a maximum length of 64KB.
/jniorio.log
This is generated by the
IOLOG command. It will contain I/O logs for all
recent Digital Input and Relay Output state changes.
/auxio.log
This is generated by the IOLOG -A command. It will contain a detailed
record of serial communications over the AUX port.
/sensorio.log
Also generated by the IOLOG -S command, this contains details of Sensor
Port communications.
/jmpserver.log
This contains log information pertaining to access and use of the
JANOS Management Protocol (JMP).
JMP is a
JSON based protocol current
recommended for JNIOR communications.
/protocol.log
This contains log information pertaining to access and use of the
legacy JNIOR Protocol.
/access.log
Contains notices of failed login attempts.
/web.log
This is a detailed WebServer log.
/tls.log
This log reports issues with SSL/TLS secure communications.
/php.log
Logs errors and event pertaining the the JANOS PHP-like scripting language.
/errors.log
Errors encountered by applications are logged here. If you understand the
reason for the logged error detail you should delete this LOG. It is
important to recognize when errors occur and thus want to see when this
log file appears. The presence of an errors.log file sets the unit's
attention flag.
/dump.log
In an extreme situation the operating system may need to shutdown and
restart. A dump is generated that can be used by INTEG to further debug
the situation. If you have updated JANOS since the dump file was created
you should delete it. The presence of a dump.log sets the unit's attention
flag.
