Performance Counters (KPIs)

This article describes the basics of how Co-browse works together with the third-party Metrics Java library to provide reporting metrics about your server's Co-browse sessions. It also gives a walk-through of how to set up a sample JMX interface in order to view the metrics the Co-browse Server creates.

Co-browse and Metrics Library

Genesys Co-browse integrates with the third-party Metrics Java library, a toolkit that support all kinds of metrics out of the box: for example, counter, timer, histogram, and gauge.

This Metric library gives you several ways to report on current values: JMX (the main method), REST (for performance testing), and Logging.

About Co-browse Metrics

Starting with release 8.5.100.05, the Co-browse Server integrates with the Metrics Library client for the Java Management Extensions (JMX) reporter interface. JMX lets you observe Co-browse metrics using JMX tools.

Co-browse Server 8.5.002 extended metrics functionality to support logging to a file and the console.

Overview of Available Co-browse Metrics

Co-browse Server generates these kinds of metrics:

  • Current count of sessions in different states (counter metric)
  • Count of completed sessions since the start of the server (counter metric)
  • Session timings (timer/histogram)
    • Agent overall rendering time (histogram)
    • Agent stages rendering time (histogram)
    • Co-browse session initialization on server side (timer)
    • Time of Customer, Agent, and Controller joining to the Co-browse session (timer)
  • Sessions interrupted without accept (counter metric).

Breakdown of Available Co-browse Metrics

Metric name Description Added in version:
ActiveSessions Sessions set to "Activated" status when session is created by Customer and joined by Agent 8.5.001
CanceledInactiveSessions Sessions canceled by initiator 8.5.001
InactiveSessions Sessions set to "Inactive" status when session is created by Customer but waiting for Agent to join 8.5.001
LiveSessions All sessions in statuses "Inactive" or "Activated". 8.5.001
NormallyEndedActiveSessions Sessions ended during period of two sides Co-browse activity 8.5.001
TerminatedByUserDisconnectionSessions Sessions ended through User timeout disconnect 8.5.001
TimeoutedInactiveSessions Sessions ended by timeout in awaiting for Agent connection 8.5.001
TotalFinishedSessions Total count of all finished sessions 8.5.001
CreateSessionAverage Histogram showing the timings for session creation on the server side 8.5.001
JoinSessionAverage Histogram showing the timings for the server join procedure for each member in a Co-browse activity 8.5.001
SlaveInitAverage Histogram showing the timings for Agent initialization after a page reload with session ID 8.5.001
SlaveGetSessionAverage Histogram showing the timings for the Agent to obtain the session environment after a page reload with session ID 8.5.001
SlaveHandshakeAverage Histogram showing the timings for the Agent handshake via CometD after a page reload with session ID 8.5.001
SlaveJoinAverage Histogram showing the timings for the Agent to join a session after a page reload with session ID 8.5.001
SlavePageDataAverage Histogram of timing for Agent got page data since page reload with session ID 8.5.001
SlaveRenderAverage Histogram showing the timings for the Agent to fully render after a page reload with session ID 8.5.001
ServerResponseTime Histogram showing the average timings for the latest N routings of data from customer browser to agent browser, where N is defined by the ServerResponseTime.slidingWindowSize option value. 8.5.002

How To Expose Co-browse metrics through the JMX interface

There are many JMX tools that you can use to observe the metrics Co-browse Server creates:

  • JConsole tool bundled with Oracle Java (TM)
  • EJTools JMX Browser
  • Panoptes
  • jManage
  • MC4J
  • Zabbix

Using JConsole to Observe Co-browse Metrics

To use JConsole to view Co-browse metrics:

  1. Connect JConsole to Co-browse Server
  2. Open the JMX panel to view the metrics

Connect JConsole to Co-browse Server

Connecting JConsole to Co-browse Server depends on the Co-browse Server process:

Connect to Co-browse started as a local java process

GCB JConsole Service.png

  1. Run jconsole.exe from the <jdk>/bin directory.
  2. In the New Connection dialog, specify the Co-browse launcher java process.

    If the Co-browse Server was started using a .bat file in the same host where JMX console is opened, specify the following process from the Local Process list:

    com.genesys.launcher.bootstrap.Bootstrap
    


Connect to Co-browse started as a server

1

If the Co-browse Server was started remotely as a server, follow these steps:

  1. Run jconsole.exe from the <jdk>/bin directory.
  2. Open setenv.bat and uncomment all lines under
    :: Uncomment for enabling JMX Remote. Memorize JMX port.
    Save your changes.
  3. Restart the Co-browse Server application.
  4. Specify host:<JMX port> in the Remote Process section:

Connect to Co-browse started as a Windows service

If you started Co-browse Server as a Windows service, first stop the service, reinstall it, and start it again, as follows:

  1. Stop the service.
  2. Open setenv.bat and find the service name in the line set SVC_NAME=
  3. Run this command:
    cobrowse.bat -service SERVICENAME remove
    to remove the service.
  4. Open setenv.bat and uncomment all lines under
     :: Uncomment for enabling JMX Remote. Memorize JMX port.
    Save your changes.
  5. Run this command:
    cobrowse.bat -service SERVICENAME install
    to install the service.
  6. Start the service.
  7. Specify host:<JMX port> from the Remote Process section, see above.


Once you connect to JConsole to Co-browse Server, you can open the JMX panel to view the metrics.

Open the JMX panel to view the metrics

  1. Click Connect in the New Connection dialog. The JMX panel opens.
  2. Open the MBeans tab and expand the Cobrowse branch. All Co-browse metrics are there.
  3. To refresh the metrics, click Refresh.

Configuring logging reporter for metrics

Co-browse Server release 8.5.002 extends metric functionality to support logging to a file and to the console.

To configure the logging reporter to log to a file or to the console:

Logging to a file

To enable logging to a file:

metrics section

In the metrics section of your Co-browse Cluster application configure the following:

log section

In the Co-browse Node application log section configure the following:

  • Set verbose to trace
  • Set <output>=<log file name> where output is all, trace, or debug.

Logging to the console

To enable logging to the console:

metrics section

In the metrics section of you Co-browse Cluster application configure the following:

log section

In the Co-browse Node application log section configure the following:

  • Set verbose to trace
  • Set <output>=<stdout> where output is all, trace, or debug.
