Oracle Tuxedo Monitoring
Overview
Oracle Tuxedo provides the framework for building scalable multi-tier client/server applications in heterogeneous distributed environments. From the Web to the Enterprise, Tuxedo users can develop, manage, and deploy distributed applications independent of the underlying hardware, operating system, network and database environment.
Monitoring Oracle Tuxedo applications can be complex, providing requests that run across multiple processes, machines, and domain boundaries. Applications Manager can help you monitor system and application data from key Tuxedo components like the bulletin board, queue and communication bridge details, transaction info, ATMI operations and service details.
Creating a new Oracle Tuxedo monitor
Oracle Tuxedo Versions Supported: Tuxedo version 6.5 and above.We are using BEA SNMP Agent and the SNMP MIBs to manage Tuxedo applications.
Prerequisites for monitoring Oracle Tuxedo: You must have Tuxedo SNMP agent installed. When you specify the SNMP community string, make sure that the community string has at least 'Read-only' privileges.
Attributes Monitored: Refer Oracle Tuxedo Monitoring Parameters to know more about the attributes monitored.
To create a Oracle Tuxedo Monitor:
- Click on New Monitor link.
- Select Oracle Tuxedo.
- Enter the Display Name of the monitor.
- Enter the Hostname of the host where the Oracle Tuxedo Server is running.
- Enter the SNMP port number , on which the Tuxedo SNMP agent is running. The default port number is 161.
- You can enter your own credential details or select preconfigured credentials details in Credentials Manager.
- Specify the SNMP community string of Tuxedo SNMP agent. The default value is 'public'. Make sure you use a community string, that has 'Read' privileges.
- Enter the timeout in seconds.
- Set the Polling interval.
- If you are adding a new monitor from the Central Server, select a Probe Server.
- Choose the Monitor Group from the combo box with which you want to associate Tuxedo server (optional). You can choose multiple groups to associate your monitor.
- Click Add Monitor(s). This discovers the Tuxedo server from the network and starts monitoring it.
Monitored Parameters
Go to the Monitors Category View by clicking the Monitors tab. Click on Oracle Tuxedo under the Middleware/Portal Table. Displayed is the Oracle Tuxedo bulk configuration view distributed into three tabs:
- Availability tab, gives the Availability history for the past 24 hours or 30 days.
- Performance tab gives the Health Status and events for the past 24 hours or 30 days.
- List view enables you to perform bulk admin configurations.
Click on the monitor name to see all the server details listed under the following tabs:
