IMPAX 6.5.1 Application Server Knowledge Base > Logging events and problems
Depending on the configuration of logging levels for your system, specific events are written to the log files. To troubleshoot your system, you must view and interpret the various entries in the logs. A new log file is created each day for each application, web service and Windows service logged. Only five days of logs are kept for each log file, and on the sixth day the oldest log is deleted and a new log is created.
There are seven log levels that can be set to identify the level of information that is collected. In the log files, each level is identified with their own prefix:
| Log Level | Description |
|---|---|
| OFF | No log file is created, and no information is written to the log file. |
FATAL
|
Identifies a very severe error that will cause the application to abort the action and close. This log level records only Fatal entries. In the log file, a Fatal message appears as: FATAL 2005.03.24 09:46:50.628 (1444) ... |
ERROR
|
Identifies error events that have occurred but have allowed the application to continue running. This log level includes both Fatal and Error entries. In the log file, an Error message appears as: ERROR 2005.05.11 21:17:20.323 (6fc) ... |
WARN
|
Identifies an action that has failed. For example, the failed action is retried, but after the first failed retry a Warn message is logged. After the maximum number of retries, an Error message is logged. This log level includes Fatal, Error, and Warn entries. In the log file, a Warn message appears as: WARN 2005.01.18 14:38:51.625 ... |
INFO
|
Indicates important information that determines the flow of data through the system. Info messages are of specific interest to service and support personnel. This log level includes Fatal, Error, Warn, and Info entries. In the log file, an Info message appears as: INFO 2005.04.28 11:18:03.760... |
DEBUG
|
Logs almost every step made by every process. Debug logs are generated by all other processes. Service personnel use debug logging to determine the state of the system leading up to an error. This log level includes Fatal, Error, Warn, Info, and Debug entries. In the log file, a Debug message appears as: DEBUG 2005.04.28 11:18:03.770... |
| ALL | All log levels are recorded in the logs. |
All log entries are structured as follows: X yyyy.mm.dd hh:mm:ss.mmm (####) [loc:user] message, where:
X is the log level
yyyy.mm.dd is the date
hh:mm:ss.mmm is the time with millisecond accuracy
(####) is the optional thread within an application that logged the entry
[loc:user] is the IP address and user ID for the machine where the log entry was triggered
message is the detailed information that identifies the event that triggered the entry
