+# Common Logging Wrapper for Python
+
+* CommonLogger.py is the module (library) to import
+* CommonLogger_test.config is an example configuration file used by CommonLogger_test.py
+* CommonLogger_test.py is an example of how to import and use the CommonLogger module
+
+## Configuration File
+
+Configure common logging for a python application in a configuration file.
+In the file, put key = value assignments
+
+* defining the filename for each log file you will create, such as
+'error=/path/error.log', 'metrics=/path/metrics.log', 'audit=/path/audit.log',
+and 'debug=/path/debug.log'.
+The name used (shown here as 'error', 'metrics', etc.) is chosen in the program, allowing a single configuration file to be
+used by numerous different programs.
+(It will be referred to below as <logKey>.)
+* defining the style of the log messages to be produced,
+using <logKey> suffixed with 'Style', as in 'errorStyle=', and one of the
+words 'error', 'metrics', 'audit' and 'debug'.
+* defining the minimum level of log messages to be retained in a log file,
+using <logKey> suffixed with 'LogLevel', as in 'errorLogLevel=WARN'.
+The levels are DEBUG, INFO, WARN, ERROR, and FATAL.
+So specifying WARN will retain only WARN, ERROR, and FATAL level
+log messages, while specifying DEBUG will retain all levels of log messages:
+DEBUG, INFO, WARN, ERROR, and FATAL.
+
+Comments may be included on any line following a '#' character.
+
+Common logging monitors the configuration file so if the file is edited
+and any its values change, then common logging will implement the changes
+in the running application.
+This enables operations to change log levels or even log filenames without
+interrupting the running application.
+
+By default, log files are rotated daily at midnight UTC, retaining 6 backup versions by default.
+
+Other strategies can be specified within the configuration file using the keywords:
+
+* rotateMethod = one of 'time', 'size', and 'none' (case insensitive)
+
+If rotateMethod is 'time', the following keywords apply:
+* backupCount = Number of rotated backup files to retain, >= 0. 0 retains *all* backups.
+* timeRotateIntervalType = one of 'S', 'M', 'H', 'D', 'W0', 'W1', 'W2', 'W3', 'W4', 'W5', 'W6', 'midnight'
+(seconds, minutes, hours, days, weekday (0=Monday), or midnight UTC)
+* timeRotateInterval = number of seconds/minutes/hours/days between rotations. (Ignored for W#.)
+
+If rotateMethod is 'size', the following keywords apply:
+* backupCount = Number of rotated backup files to retain, >= 0. 0 retains *no* backups.
+* sizeMaxBytes = maximum number of bytes allowed in the file before rotation
+* sizeRotateMode = for now, this defaults to 'a' and may only be specified as 'a'.
+It is passed to the underlying Python Logging methods.
+
+
+Besides logging to a file, it is also possible to send log messages elsewhere,
+using <logKey> suffixed with 'LogType'.
+You can set <logKey>LogType to any of 'filelogger', 'stdoutlogger', 'stderrlogger', 'socketlogger' orlogger 'null' (case insensitive).
+
+* 'filelogger' is the default specifying logging to a file.
+* 'stdoutlogger' and 'stderrlogger' send the output to the corresponding output streams.
+* 'socketlogger' will send the output to the corresponding socket host.
+* 'nulllogger' turns off logging.
+
+If <logKey>LogType is 'socket', the following keywords apply:
+* <logKey>SocketHost = FQDN or IP address for a host to sent the logs to
+* <logKey>SocketPort = the port (> 0) to open on that host
+
+This is an example configuration file:
+
+ error = /var/log/DCAE/vPRO/error.log
+ errorLogLevel = WARN
+ errorStyle = error
+
+ metrics = /var/log/DCAE/vPRO/metrics.log
+ metricsLogLevel = INFO
+ metricsStyle = metrics
+
+ audit = /var/log/DCAE/vPRO/audit.log
+ auditLogLevel = INFO
+ auditStyle = audit
+
+ debug = /var/log/DCAE/vPRO/debug.log
+ debugLogLevel = DEBUG
+ debugStyle = debug
+
+## Coding Python Applications to Produce ONAP Common Logging
+
+A python application uses common logging by importing the CommonLogger
+module, instantiating a CommonLogger object for each log file, and then
+invoking each object's debug, info, warn, error, or fatal methods to log
+messages to the file. There are four styles of logging:
+error/info logs, debug logs, audit logs, and metrics logs.
+The difference between the types of logs is in the list of fields that
+are printed out.
+
+### Importing the CommonLogger Module
+
+Importing the CommonLogger module is typical:
+
+ sys.path.append("/opt/app/dcae-commonlogging/python")
+ import CommonLogger
+
+### Creating a CommonLogger object:
+
+When creating a CommonLogger object, three arguments are required:
+
+1. The configuration filename.
+2. The keyword name in the configuration file that
+defines the log filename and parameters controlling rotation of the logfiles.
+(This is the <logKey> referred to above.)
+3. The keyword arguments for style and to set default values for the log record fields.
+
+The style of the log (one of CommonLoger.DebugFile, CommonLogger.AuditFile,
+CommonLogger.MetricsFile and CommonLogger.ErrorFile), must be specified either
+in the configuration file (e.g., errorStyle=error or metricsStyle=metrics) or
+using a style= keyword and one of the values: CommonLoger.DebugFile,
+CommonLogger.AuditFile, CommonLogger.MetricsFile and CommonLogger.ErrorFile.
+
+Keyword arguments for log record fields are as follows.
+The annotation indicates whether the field is included in
+(d) debug logs, (a) audit logs, (m) metrics logs, and (e) error logs.
+
+* requestID (dame)
+* serviceInstanceID (am)
+* threadID (am)
+* serverName (am)
+* serviceName (am)
+* instanceUUID (am)
+* severity (am)
+* serverIPAddress (am)
+* server (am)
+* IPAddress (am)
+* className (am)
+* timer (am)
+* partnerName (ame)
+* targetEntity (me)
+* targetServiceName (me)
+* statusCode (am)
+* responseCode (am)
+* responseDescription (am)
+* processKey (am)
+* targetVirtualEntity (m)
+* customField1 (am)
+* customField2 (am)
+* customField3 (am)
+* customField4 (am)
+* errorCategory (e)
+* errorCode (e)
+* errorDescription (e)
+
+Sample code:
+
+ """ The style can be specified here or in the config file using errorStyle. """
+ errorLog = CommonLogger.CommonLogger("my.config", "error", style=CommonLogger.ErrorFile, serviceName="DCAE/vPRO")
+ infoLog = CommonLogger.CommonLogger("my.config", "info", serviceName="DCAE/vPRO")
+
+### Setting default values for fields:
+
+The object's setFields method allows keyword arguments changing default values for the log record fields.
+
+ errorLog.setFields(serviceName="DCAE/vPRO", threadID="thread-2")
+
+### Calling Methods
+
+The object's debug(), info(), warn(), error(), and fatal() methods require a detailMessage argument
+(which can be a zero-length string) and allow the keyword arguments for setting log record field
+values for just that one message.
+Any newlines or '|' characters in the message will be changed to a single space.
+
+ infoLog.info("Something benign happened.")
+ errorLog.fatal("Something very bad happened.", threadID="thread-4")
+
+### Output
+
+Note that no field may contain the '|' (pipe) field separation character, as that
+character is used as the separator between fields.
+Here is a possible example of a produced log record:
+
+ 2015-10-12T15:56:43,182+00:00|netman@localdcae.att.com:~/vPRO_trinity/vPRO.py:905+2015-08-20 20:57:14.463426||||DCAE/vPRO:App-C.Restart|d4d5fc66-70f9-11e5-b0b1-005056866a82|INFO||135.16.76.33|mtvpro01dev1.dev.att.com|||1001|Finished Restart
+ 2016-12-09T23:06:02,314+00:00||MainThread|DCAE/vPRO|||||||a FATAL message for the error log
+
+### Example Code
+
+The main within CommonLogger.py contains a regression test of the CommonLogger methods.
+
+CommonLogger_test.py contains a complete demonstration of a python application
+using the python CommonLogging wrapper module, including creating UUIDs,
+setting default log field values, and timing operations.
+
+## Upgrading from Previous Versions of CommonLogger
+
+The current version of CommonLogger is 99% compatible with earlier versions of CommonLogger.
+The key change, due to update ONAP logging requirements, is the choice to use different lists
+of fields in different types of log files.
+This required adding a mandatory "style" to be given, which we chose to do using either a
+new keyword in the configuration file, or using a new parameter keyword when creating the logger.
