WebSphere Server Monitoring


Create a New Monitor

The supported versions of WebSphere Servers are 5.x, 6.x, 7.x, 8.x and 9.x

Prerequisites for Websphere Monitoring:
For Applications Manager to collect data from WebSphere Application Server, configurations are required at the Performance Monitoring Infrastructure (PMI) specification level. Refer Prerequisites Section for configuration details.

To create a WebSphere Server Monitor

  1. Click on New Monitor link.
  2. Select WebSphere Server.
  3. Select the Deployment Mode as Base or Network Deployment.
  4. For Base Mode, Enter the Host name/IP Address of the host in which websphere application server is running.
    For Network Deployment, enter the Host name/IP Address of the websphere application server in which the perf servlet is installed. This will automatically discover all the WebSphere servers in Network Deployment.
  5. Enter the SubNetMask of the network.
  6. Enter the HTTP Transport Port (9080 by default).
  7. Enter the polling interval time in minutes.
  8. If you are adding a new monitor from an Admin Server, select a Managed Server.
  9. Select the version of the WebSphere to be monitored - 5.x, 6.x, 7.x, 8.x and 9.x
  10. Enter the port number of the SOAP Connector (8880 by default).
  11. If you want to monitor WebSphere through SSL mode, select the SSL is enabled checkbox.
  12. Enter the User Name and Password, if Global Security is enabled.
  13. In Network Deployment Mode, Enter the Network Deployer's Host and SOAP Port (Default : 8879).
  14. Choose the Monitor Group from the combo box with which you want to associate WebSphere Server Monitor (optional). You can choose multiple groups to associate your monitor.
  15. Click Add Monitor(s). This discovers WebSphere server from the network and starts monitoring them.

Note:
Applications Manager has been tested for WebSphere versions of English, German, Japanese and Chinese languages. In the Network Deployment mode, the child monitors which are automatically discovered cannot be deleted from the list view. If a user tries to delete a child monitor, it will get added again in next poll of the Parent monitor. Child monitors will be deleted only if the parent monitor is deleted. If they want to stop data collection(don't want to monitor) for child monitors, they need to mention those child monitors in Exclude list of the parent monitor in edit monitor page. If they mentioned it in exclude list of parent monitor page, then those child monitors will be unmanaged and data collection stops for those monitors.

Monitored Parameters

The 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 individual monitors listed, to view the following information

WebSphere servers are monitored based on the attributes listed under the following tabs:

The monitoring details of the server are represented graphically that helps to understand the parameters with ease. You can also configure thresholds to the attributes monitored by the server based on these details.

Monitor Details

ParametersDescription
Deployment Mode The deployment mode of the WebSphere server. You can choose either Base or Network Deployment.If you select:
  • Base Mode, enter the Host Name/IP Address of the host in which the WebSphere application server is running.
  • Network Deployment, enter the Host name/IP Address of the WebSphere Application server in which the perf servlet is installed. This will automatically discover all the WebSphere servers in Network Deployment.
WebSphere Version Denotes the version of the WebSphere server monitor.
Port Refers to HTTP Transport port.
Subnet Mask The subNetMask of the WebSphere server.
Do not resolve DNS name If you have multiple system IP addresses configured with a single DNS name, select the ‘Do not resolve DNS name’ option under‘Advancedsection.
Network Deployer Host, Network Deployer SOAP Port If you have chosen the ‘Network Deployment’ mode, specify the Network Deployer Host and Network Deployer SOAP Port values. The default SOAP port is 8879.
SSL is enabled If you want to monitor WebSphere through SSL mode, select the ‘SSL is enabled’ checkbox.
App Servers to Monitor If you want to monitor selected app servers running in the WebSphere server, select the ‘Advanced Options’ checkbox and specify the app servers in the ‘App Servers to Monitor’ field. If you want to monitor all the app servers in the WebSphere server, leave this field empty.
