WebLogic Servers View

These displays present performance metrics and alert statuses for all Oracle WebLogic Servers and Clusters. Clicking WebLogic Servers from the left menu opens the WebLogic Servers Table display, which shows all available utilization metrics for all Oracle® WebLogic servers in a tabular format. The following displays are available:

• Servers Heatmap: Opens the WebLogic Servers Heatmap display, which shows status and alerts for all Oracle® WebLogic servers in a heatmap.
• Clusters Table: Opens the WebLogic Clusters Table display, which enables you to track utilization and performance metrics for all clusters on a particular domain, or on all domains.

 

WebLogic Servers Table

This display provides utilization metrics for all WebLogic Servers for a particular domain in a tabular format. Each row in this table includes heap, processing, thread, and version metrics (among others) for a particular server. Click a column header to sort column data in numerical or alphabetical order. Double-click on a table row to drill-down to the WebLogic Server Summary display and view metrics for that particular server. You can click on the drop down list in the display title to toggle between commonly accessed displays.

WebLogic Servers Heatmap

Clicking Servers Heatmap in the left/navigation menu opens the WebLogic Servers Heatmap display, which allows you to view the status and alerts of all Oracle® WebLogic servers. You can view the servers in the heatmap based on the following metrics: Alert Severity, Alert Count, Jvm CPU %, Host CPU %, Jvm Memory %, Open Sockets, Thread Total Count, and Hogging Threads.

The heatmap is organized by host, each rectangle representing a server. The rectangle color indicates the most critical alert state. Click on a node to drill-down to the WebLogic Server Applications Summary display and view metrics for a particular connection. You can toggle between the commonly accessed displays by clicking the display title’s drop down list. Mouse-over rectangles to view more details about host performance and status.

Heatmap

 

Log Scale

This option enables visualization on a logarithmic scale, and should be used when the range in your data is very broad. For example, if you have data that ranges from the tens to the thousands, then data in the range of tens will be neglected visually if you do not check this option. This option makes data on both extreme ranges visible by using the logarithmic of the values rather than the actual values.

 

 

Metric

Select the metric driving the heatmap display. The default is Alert Severity. Each Metric has a color gradient bar that maps values to colors. The heatmap organizes the instances by host, where each rectangle represents an instance. Mouse-over any rectangle to display the current values of the metrics for the instance. Click on a rectangle to drill-down to the associated WebLogic Server Applications Summary display for a detailed view of metrics for that particular domain.

 

 

Alert Severity

The maximum alert level in the item (index) associated with the rectangle. Values range from 0 to 2, as indicated in the color gradient bar , where 2 is the greatest Alert Severity.

2 -- Metrics that have exceeded their specified ALARMLEVEL threshold and have an Alert Severity value of 2 are shown in red. For a given rectangle, this indicates that one or more metrics have exceeded their alarm threshold.

1 -- Metrics that have exceeded their specified WARNINGLEVEL threshold and have an Alert Severity value of 1 are shown in yellow. For a given rectangle, this indicates that one or more metrics have exceeded their warning threshold.

0 -- Metrics that have not exceeded either specified threshold have an Alert Severity value of 0 and are shown in green. For a given rectangle, this indicates that no metrics have exceeded a specified alert threshold.

 

 

  

The total number of alarm and warning alerts in a given item (index) associated with the rectangle.

The color gradient bar shows the range of the value/color mapping. The numerical values in the gradient bar range from 0 to the maximum count of alerts in the heatmap. The middle value in the gradient bar indicates the middle value of the range.

 

 

Jvm CPU %

The percentage of JVM CPU currently being used in a given item (index) associated with the rectangle. The color gradient bar shows the range of the value/color mapping. The numerical values in the gradient bar range from 0 to the alert threshold of WlsServerCpuHigh. The middle value in the gradient bar indicates the middle value of the range.

 

 

Host CPU %

The percentage of Host CPU currently being used in a given item (index) associated with the rectangle. The color gradient bar shows the range of the value/color mapping. The numerical values in the gradient bar range from 0 to the alert threshold of WlsServerHostCpuHigh. The middle value in the gradient bar indicates the middle value of the range.

 

 

JVM Memory %

The percentage of JVM Memory currently being used in a given item (index) associated with the rectangle. The color gradient bar shows the range of the value/color mapping. The numerical values in the gradient bar range from 0 to the alert threshold of WlsMemoryUsageHigh. The middle value in the gradient bar indicates the middle value of the range.

 

 

Open Sockets

The total number of open sockets currently being used in a given item (index) associated with the rectangle. The color gradient bar shows the range of the value/color mapping. The numerical values in the gradient bar range from 0 to the alert threshold of WlsOpenSocketsHigh. The middle value in the gradient bar indicates the middle value of the range.

 

 

Thread Total Count

The total number of threads in a given item (index) associated with the rectangle. The color gradient bar shows the range of the value/color mapping. The numerical values in the gradient bar range from 0 to the alert threshold of WlsThreadsTotalHigh. The middle value in the gradient bar indicates the middle value of the range.

 

 

Hogging Threads

The total number of hogging threads currently being used in a given item (index) associated with the rectangle. The color gradient bar shows the range of the value/color mapping. The numerical values in the gradient bar range from 0 to the alert threshold of WlsHoggingThreadsHigh. The middle value in the gradient bar indicates the middle value of the range.
