GH Viewer - Monitoring for TIBCO Rendezvous, TIBCO EMS and SOA

GH Viewer is Green Hat's open, flexible monitoring platform for distributed technologies, including TIBCO's Rendezvous (RV), Hawk and EMS. In this section you can learn how you can monitor your TIBCO RV network using GH Viewer. Information on using GH Viewer with TIBCO Hawk and TIBCO EMS is provided elsewhere.

How much of your data is reaching its intended destination on the first attempt? Who is the biggest producer of data on the network right now, and who has been producing the most data over the past 24 hours? Who is the slowest machine on the network, are they running an old version of Rendezvous?

Your application may be working fine on the surface, producers are publishing, consumers are getting the data they are supposed to, and superficially everything appears to be functioning correctly. But is it really?

Many tools provide information on how many packets are on the network, but without protocol specific information, it is not possible to tell if they are good packets, or bad ones. A network with 1000 packets per second might be fine, if all the packets are data packets, but if they are error packets, there is a real problem. A sniffer cannot give you that information.

GH Viewer, Green Hat's performance monitoring system, understands Rendezvous (RV) traffic, so it can tell the difference between good packets and bad ones -
  • Minimises downtime by instantly identifying problem machines.

  • Historical access to data allows extensive analysis of problems by remote personnel.

  • Information provided enables preventive maintenance.

  • Enables close investigation of incidents after they have occurred to determine cause.

  • Summary screen shows version number and most recent start time, allowing simple system problems to be spotted effortlessly.

  • Real-time graphs of all variables, including packets sent, received and missed.

  • Top-ten subscribers, publishers and slow machines. Log of all errors.

  • Save and load functions permit traces of "busy" days to be preserved for comparison in the future, allowing relative system performance to be determined.

Now in its 4th version, GH Viewer provides an open platform for monitoring and alerting, not just for TIBCO, but for any data you like. A simple plug-in interface enables customers to include their own unique sources of monitoring information, and then use the power of GH Viewer to build displays for that information alongside GH Viewer's built-in sources.

For the beginner, Green Hat have provided several powerful displays to help you find problems in your TIBCO RV network. The advanced user can use GH Viewer to build their own monitoring tool.

GH Viewer in Detail

Monitor Traffic

By providing a constantly updating real-time display of your network traffic, GH Viewer lets you monitor the health of the network. Although the Rendezvous daemon itself contains an HTTP interface, it is hard to get an overall picture of what the network is doing. GH Viewer removes this blind spot.

Alerts

GH Viewer incorporates a powerful rules engine. Users build rules to draw their attention to specific conditions. When a rule matches, configurable actions take place, including SNMP traps, messages, emails or command execution. An API allows the addition of new, custom actions, e.g. to interface with in-house systems.

Store Data

In the course of normal operation, GH Viewer builds up profiles of TIBCO Rendezvous (RV) network performance information. These profiles are stored for as long as the user wishes to keep them. This can provide valuable information about the impact of a new release of software on the network performance. Used proactively, this information can help developers understand the changes they have made. Used reactively, it can help support staff prove that a new release has a significantly different network profile from a previous release.

GH Viewer works with a variety of leading databases to store your monitoring information for as long as you want.

View Summaries

GH Viewer provides a summary screen showing all hosts together with key information about those hosts, such as Rendezvous (RV) version number. This makes it very easy to see which machines still require upgrading, or have not been rebooted recently. Plan Capacity

By providing historic information on existing systems, and statistics on new systems, GH Viewer can be used for capacity planning a TIBCO Rendezvous Network, before roll-outs occur.

Current traffic can be instantly compared with historical traffic, showing whether today is busier than past days. Any historical sample can be compared with any other, using a simple dialog to configure the data source. The flexibility of GH Viewer allows it to pull together a wide variety of data from several different networks and display them together.

Using the graph configurator, users can set up any combination of graph traces and axes to display the data in the clearest, most appropriate, way.

The tool provides a zooming function to allow problems to be examined in detail, down to the individual host.
