Critical Applications Subagent

Atlanta, Georgia, October 8, 1997 - Mission-critical software applications can now be monitored and controlled using the same tools which manage mission-critical hardware. SNMP Research International, Inc. announces the Critical Application Subagent which is a vital new extension to the EMANATE Run-time Extensible Agent System for monitoring and control of mission-critical applications. The Critical Application Subagent monitors applications and carries out suitable actions whenever one of these applications terminates.

Managers of networks know that their task is not complete unless the applications that help the organization fulfill its mission remain up and running. However, many solutions which attempt to address applications management are based upon proprietary tools which further fragment the manager's job. The Critical Applications Subagent uses SNMP, the most widely used open management framework and the basis for all popular manager stations.

Other solutions to the applications management task are based on an open management framework, but offer more information than the manager needs to know. This additional information makes these solutions difficult to implement and use. The Critical Applications Subagent is focused primarily on whether an application is running or not. It can be configured to take action immediately to restart the application and to notify managers so that the manager can address more complex management issues using other available tools.

The Critical Application Subagent is architecturally the parent of the applications it manages, so it starts the managed applications. As a result, the Subagent is informed if the application exits. Then, the Critical Applications Subagent has the ability to examine the termination status, restart the application and send a trap to notify the management station that a critical application is down, including an indication of which critical application is down.

At other times, the Critical Application Subagent can be queried about data related to the execution status of the applications. For instance, the Critical Applications Subagent can report the execution state of the applications, time and exit code for the last time a critical application terminated, and statistics on how many times an application has been restarted. If the administrator so chooses, the Critical Application Subagent can be configured to also send a trap when all applications are running.

The Critical Application Subagent permits the manager to add new applications in the field without restarting the Critical Application Subagent. The manager can also change the actions which are to be taken when an application terminates. Not only can one configure which applications are monitored by the Critical Application Subagent, but the applications may be started or stopped using SNMP set operations. Finally their parameters can also be controlled.

For example, an administrator can use SNMP to switch from a test system to a production system if excessive failures are encountered.

Since the EMANATE Master Agent supports industrial strength security using SNMPv2* or SNMPv3, malicious use of the Critical Application Subagent can easily be avoided. SNMPv2* and SNMPv3 provide facilities for limiting access to certain objects to limited sets of users. If desired, all unsecured SNMPv1 and SNMPv2c access to the Critical Application Subagent information can be prohibited.

The Critical Application Subagent is licensed in either full source code or in binary form. Quantity discounts are available. An EMANATE Master Agent is also required.

About SNMP Research International, Inc.:

SNMP Research International produces a complete family of management products based on SNMPv1, SNMPv2c, SNMPv2*, SNMPv3, and other protocols for agents, management stations, and mid-level managers. These products form the basis of many of today's SNMP products offered by leading networking companies. The founder of SNMP Research, Dr. Jeff Case, has long been a contributor in the area of SNMP and has authored or coauthored many standards documents and articles on the topic. As a result of his efforts, SNMP Research is in a leadership position with respect to defining the standards and constructing implementations based on SNMP, the standard protocol for TCP/IP management.
