CWATCH

CWATCH monitors the Oracle JavaCAPS 5.1.x and 6.x integration suite. CWATCH communicates with the JavaCAPS Integration Server and the Sun Enterprise Manager Server, detects and reports problems and generates a breakdown of all monitored components.

Advantages

CWATCH monitors reliably, stand-alone, unobserved and 24x7 the components of JavaCAPS. If a problem is detected CWATCH alarms the administrator via configurable channels. This allows to react in a timely fashion, or even to solve problems in their beginning, before end users take notice. CWATCH reduces the effort operating JavaCAPS as it monitors automatically and in short intervals that otherwise would have to be done manually. Using the summary view of the observation results and the enterprise manager alerts, it is possible, thanks to the monitoring web application of CWATCH, to find sources of error quickly and to solve potential problems.

How it works

CWATCH is comprised of 3 components that are described below.

1. Configuration component:

CwatchConfigGui provides a graphical user interface to configure CWATCH. The essential part of the configuration is the watchlist. You can specify what you would like to monitor for each component of JavaCAPS individually in the watchlist. Furthermore, the global settings for alarming are configured in this program.

2. Observation component:

The CWATCH Agent is the observation component, that continuously analyzes the current status of JavaCAPS. In case of an error an alarm will be sent. After the problem is solved CWATCH is capable to send an "all-clear" signal. The CWATCH Agent is a very stable multi threaded program. It can be started multiple times, each instance responsible for its own scope. In the viewing applications, the different scopes can be viewed separately.

Options to start CWATCH

  • CwatchMain is a command line program that is started manually or from an operating systems scheduler.
  • CwatchService is started as a service and runs in the background.
CWATCH monitors:
  • Status of integration servers, JMS servers, JCD services
  • Socket connection status to other systems
  • The number of messages in queues and topics. If STCMS destinations are monitored, even the age of the messages can be checked
  • Components alerts in the Enterprise Manager Servers
  • Usage of the JVM Heap and the PermGen space in the heap. By request it calculates an average of several samples, to avoid false reports on peaks.
  • The message throughput of Java collaborations. Notifications are sent, if no messages were processed in a certain periode of time
Special functions:
  • Restart of JCD's
  • Ignore problems within a configured period
  • Notification when the problem is resolved
  • e-Mail Notification uses a global list of recipients, or can be set individually per component
  • Switch alerting on and off individually
The alarming channels are:
  • e-Mail
  • Execution of a program
  • Log files
  • RSS feed
  • SNMP V2 traps
  • TwitterŽ
3. Display component:

The web application cwatchmon and the graphical user interface CwatchMonitor are used to provide a overview of the monitored Java CAPS components an their status information.

The GUI is divided into the following parts:
  • A total status overview
  • An overview of all detected problems
  • Enterprise Manager Alerts overview
    • Alerts details view
Screenshots

CWATCH Monitor - Status overview

Lists the monitored components with their status, message counter, problem details, and more. All columns may be sorted. Status overview automatically refreshes every minute, no need to that manually.
 
CWATCH Monitor - Problem overview

Provides an overview of all failed components. This view shows all problems at a glance, you do not have to scroll through the status-overview.
 
CWATCH Monitor - Alerts overview

Shows all Enterprise Manager alerts with severity of 'warning' (or worse). Alerts are deleted automatically from Enterprise Manager after they are successfully inserted into the CWATCH database. This saves you tedious, manual deletion via Enterprise Manager. A well-arranged table with the 'alert message' and the number of alerts is provided. Clicking an alert opens the appropriate detail-table for this alert. There you may delete the alerts.

A long list is rendered page-by-page allowing standard navigation.
