Creating a new WebLogic server monitor

Supported Versions: Following versions of WebLogic Servers can be monitored by Applications Manager:

  • WebLogic 6.1
  • WebLogic 7.x
  • WebLogic 8.x
  • WebLogic 9.x
  • WebLogic 10.x (WebLogic 11g)
  • WebLogic 12.x and above

To create a new WebLogic monitor, follow the steps given below:

  1. Click on New Monitor link.
  2. Select WebLogic Server.
  3. Enter a Display Name for the monitor.
  4. Enter the IP Address/ hostname of the host.
  5. Select the version of your Weblogic Server from drop-down menu.
  6. From the box, select whether SSL is enabled or not.
  7. Enter the port number in which WebLogic is running.
  8. You can enter your own credential details or select preconfigured credentials from details in Credentials Manager. If you wish to enter your own credentials, specify WebLogic version, username and password details for this monitor.
    9. Select the action you want to perform on deleted resources using the Action on Deleted Resources field.
  9. Choose one of the following from Discover Clusters and Servers option:
    • Do not discover: Clusters and managed servers will not be discovered.
    • Discover but do not monitor metrics: Clusters and managed servers will be discovered and added as separate monitors, but will be in unmanaged state.
    • Discover and monitor metrics: Clusters and managed servers will be discovered, added as separate monitors and metric data will be collected.

    Note: Clusters are added as Cluster Monitor type.

  10. Enter the polling interval time in minutes.
  11. If you are adding a new monitor from an Admin Server, select a Managed Server.
  12. Provide the monitor-specific authentication information, such as user name and password.
  13. Choose the Monitor Group from the combo box with which you want to associate WebLogic Server Monitor (optional). You can choose multiple groups to associate your monitor.
  14. Click Add Monitor(s). This discovers WebLogic server from the network and starts monitoring them.
Note:
  • The ports that need to be opened when the Weblogic Monitor is behind the firewall: Two-way communication between WebLogic listening port (Default : 7001) and Applications Manager web server port (default : 9090).

Monitored Parameters

WebLogic servers are monitored based on a few parameters or the attributes. These attributes provide information about the functioning of the Monitors of WebLogic server and you can also receive alarms based on the thresholds configured on the numerical attributes of the server.

  • 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.

JVM Heap Usage

Parameters Description
Minimum Heap Size The minimum amount of heap memory that was used by the WebLogic server. (KB)
Maximum Heap Size The maximum amount of heap memory that was used by the WebLogic server. (KB)
Average Heap Size The average amount of heap memory that was used by the WebLogic server. (KB)
Total Heap Size The total amount of heap memory allocated to the WebLogic server. (KB)
Current Heap Size The amount of heap memory currently available in the WebLogic server. (KB)
Current Heap Size (%) The percentage of the amount of heap memory currently available in the WebLogic server. (%)
Server Response Time
Server Response Time Server Response Time is the time the server takes to respond to a user request. Here, it is calculated as the time that the Weblogic Server takes to establish a connection with and respond to a request from Applications Manager. You can also track the minumum, maximum, average and current response time of your Weblogic Servers.

Threads waiting for connection Mentions the number of threads waiting for the connection.
JDBC Active Connections Mentions the number of active connections made to the monitor.
Total Connections Specifies the number of database connection pool.
Pool State Specifies the state of the pool Running/Suspended
JDBC Connection Leak Count There can be some problems in connections that are checked out from the connection pool but are not returned back to the pool and they are specified using the parameter.
JDBC Active Connection in % Amount of active connections in %

Thread Pool

Parameters Description
Idle Threads Count Specifies the threads that are idle or not used.
