Cisco Unified JTAPI Alarms and Services


The Cisco Unified JTAPI alarms and services consists of a set of classes and interfaces that expose the additional functionality not readily exposed in JTAPI 1.2 specification but are available in Cisco Unified Communications Manager. Developers can use the classes and interfaces to create new applications or modify existing classes and interfaces to create new methods.

This chapter describes the alarms and services that are available for implementation in a Cisco Unified Communications Manager and contains the following sections:

Alarm Class Hierarchy

The following class hierarchy is contained in the com.cisco.services.alarm package.

java.lang.Object

         com.cisco.services.alarm.AlarmManager

         com.cisco.services.alarm.DefaultAlarm (implements com.cisco.services.alarm.Alarm)

         com.cisco.services.alarm.DefaultAlarmWriter (implements                com.cisco.services.alarm.AlarmWriter)

         com.cisco.services.alarm.ParameterList

AlarmManager

The AlarmManager is used to create Alarm objects. The AlarmManager is created with a facility and AlarmService hostname and port. All alarms created by the factory will be associated with this facility. This class also maintains a reference to a single AlarmWriter that can be used system wide. An application can make use of this AlarmWriter. AlarmManager exposes a default implementation of an AlarmWriter. Applications can override this with a user defined implementation of their own AlarmWriter.

Usage:

AlarmManager AlarmManager = new AlarmManager(facilityName, alarmServiceHost, alarmServicePort, debugTrace, errorTrace);

Alarms are created by the factory by supplying the alarmName (mnemonic), subfacility and severity Alarms can be cached for use in different parts of the application. During a send alarm applications can specify the variable parameters that offer specific information to the AlarmService.

Usage:

Typically applications will maintain their own AlarmManager instance. Applications will also have to set a debug and error trace to enable the alarm tracing to also be sent to the existing trace destinations.

Setup the manager and writer classes:
AlarmWriter alarmWriter = new DefaultAlarmWriter(port, alarmServiceHost);
AlarmManager alarmManager = new AlarmManager("AA_IVR", alarmWriter, debugTrace, errorTrace);

Generating the Alarms:
create an alarm for the subfacility and a default severity.
Alarm alarm = alarmManager.createAlarm("HTTPSS", Alarm.INFORMATIONAL);
alarm.send("090T") sends the alarm with the mnemonic
alarm.send("090T", "Port is stuck", "CTIPort01") or with a mnemonic and parameter

Alarm Interface Hierarchy

The following interface hierarchy is contained in the com.cisco.services.alarm package.

com.cisco.services.alarm.Alarm

com.cisco.services.alarm.AlarmWriter

Alarm

The Alarm interface is used to define Alarms in. An Alarm has an XML representation that it must adhere to in order to be recognized by the Alarm Service, with a DTD as shown below. An application can implement this interface or use the AlarmFactory to generate Alarms of the correct format. The Alarm is the a specification that needs to be sent to an AlarmService that will take some action based on the Alarm. Using this specification the AlarmService will access definitions available in a catalog. This catalog is maintained by the user requiring the Alarm function to effect the appropriate action for the Alarm. The severity specified the Alarm can over-ride the severity associated with this Alarm in the catalog. If no severity is specified in the Alarm the catalog severity is used.

Alarm severities are derived from Syslog and are defined as follows:

 0 = EMERGENCIES System unusable
1 = ALERTS Immediate action needed
2 = CRITICAL Critical conditions
3 = ERROR Error conditions
4 = WARNING Warning conditions
5 = NOTIFICATION Normal but significant condition
6 = INFORMATIONAL Informational messages only
7 = DEBUGGING Debugging messages

LogFileTraceWriter

This class extends the BaseTraceWriter class to implement a TraceWriter that writes to a set of log files, rotating among them as each becomes filled to a specified capacity and stores them in a specified directory.

Each of the log files is named according to a pattern controlled by three properties, CurrentFile, FileNameBase, and FileExtension. The CurrentFile property determines which log file, by ordinal number, is being written at present, the FileNameBase property determines the prefix of each log file name, and the FileExtension property determines the suffix, e.g. "txt". From these properties, log files are named FileNameBase LeadingZeroPadding CurrentFile.FileExtension. The CurrentFile property takes on a value from 1 to the value of the MaxFiles property. Note that the CurrentFile property, when converted to a String, is padded with leading zeroes depending on the values of the MaxFiles and CurrentFile properties. An index file tracks the index of the last file written. If the logFileWriter is recreated (for example if an application is restarted) new files will continue from the last written index.

Where the log files are stored is determined by the path, dirNameBase, useSameDir. If a path is not specified, the current path is used as default. If a dirNameBase is not specified, it write log files in the path. Depending upon whether useSameDir is true or false, files are written to the same directory or a new directory, each time an instance of LogFileTraceWriter is created. In case new directories are being made each time, the directory name will consist of the dirNameBase and a number, separated by an '_'. The number is one more than the greatest number associated with directories with the same dirNameBame in the path. While specifying the path, you may use either a "/" or "\\", but not "\"

The LogFileTraceWriter keeps track of how many bytes have been written to the current log file. When that number grows within approximately LogFileTraceWriter.ROLLOVER_THRESHOLD bytes, tracing continues to the next file, which is either CurrentFile + 1 if CurrentFile is not equal to MaxFiles, or 1 if CurrentFile is equal to MaxFiles.


Note All properties of this class are specified in the constructor; there is no way to change them dynamically. Caveat: If two instances of LogFileTraceWriter are created with the same path and dirNameBase, and useSameDir is true, they may write to the same file.


Example

The following code instantiates a LogFileTraceWriter that will create log files called "MyLog01.log" through "MyLog12.log". Each file will grow to approximately 100K bytes in size before the next file is created:

LogFileTraceWriter out = new LogFileTraceWriter ( "MyLog", "log", 12, 100 * 1024 ); will create a log file TraceWriter which will rotate traces to 12 files from Mylog01.log and Mylog12.log with a file size of 100 KBytes. By default the tracing is set to the HIGHEST_LEVEL.

Example

The following code constructs a LogFileTraceWriter which stores the log files in the path "c:/LogFiles" in a sub directory, "Run". The files will be named MyLogXX.log. The number of rotating files will be 12 with a size of 100 KB. The same directory gets used for each instance of the application.

LogFileTraceWriter out = new LogFileTraceWriter ("c:/logFiles", "Run", "MyLog", "log", 12, 100*1024, true);

Trace

The Trace interface defines the methods that allow application tracing. Trace also defines the standard trace types as specified by Syslog Trace Logging.Syslog currently defines 8 levels of trace. The severity of the message is indicated in the trace as a number ranging between [0-7] (0 and 7 included). Currently 7 is HIGHEST_LEVEL and 0 is the LOWEST_LEVEL trace. All 8 levels are predefined here as static int types for reference in tracing sub-system implementations.

The severities traced are as follows:

 0 = EMERGENCIES System unusable
1 = ALERTS Immediate action needed
2 = CRITICAL Critical conditions
3 = ERROR Error conditions
4 = WARNING Warning conditions
5 = NOTIFICATION Normal but significant condition
6 = INFORMATIONAL Informational messages only
7 = DEBUGGING Debugging messages

TraceManager

The TraceManager interface defines the methods that allow applications trace management.

Typically, an application obtains only one TraceManager object. All Trace objects are created by default: Predefined Trace in accordance with Syslog definitions are:

 ConditionalTraces: INFORMATIONAL, DEBUGGING, NOTIFICATION, WARNING
 UnconditionalTraces: ERROR, CRITICAL, ALERTS, EMERGENCIES

Facilities/Sub-Facilities:

Facility—A code consisting of two or more uppercase letters that indicate the facility to which the message refers. A facility can be a hardware device, a protocol, or a module of the system software.

SubFacility—A code consisting of two or more uppercase letters that indicate the sub-facility to which the message refers. A sub-facility can be a hardware device component, a protocol unit, or a sub-module of the system software.

By default all 8 Conditional and UnConditional Traces are created for the Facility and 8 for each of the subFacilities In order to use the DEBUGGING trace for the parent FACILITY, for example, the application needs to use the getConditionalTrace( "DEBUGGING" ) method of this object.

In order to use the DEBUGGING trace for the SUBFACILITY, for example, the application needs to use the getConditionalTrace( SUBFACILITY + "_" + "DEBUGGING" ) method of this object or use the getConditionalTrace( SUBFACILITY, "DEBUGGING" ) method.

System wide TraceWriterManager is set through the setTraceWriterManager method provided by this interface.

The Trace Manager object also allows the application to enable or disable tracing for all trace through the enableAll() and disableAll() methods.

TraceWriter

The TraceWriter interface abstracts the details of trace message output. The TraceWriter uses its enabled method to advertise whether or not the print and println methods will have any effect. Users of TraceWriter should use the value returned by the getEnabled method as an indication of whether they should invoke the print and println methods at all.

TraceWriterManager

TraceWriterManager contains the list of TraceWriter objects that are used to implement the tracing. The list is populated at startup from the switches in a .ini file. A LogFileTraceWriter, a ConsoleTraceWriter, and a SyslogTraceWriter are available. Users can override the existing TraceWriters by setting a user implemented TraceWriter[] or adding to the existing TraceWriters. This makes it possible to add other TraceWriters that can function along with existing trace writers.
