IBM MQ Topic Subscribers Table

This display allows you to view current alert status and performance metrics of all topic subscribers on a specific MQ broker in a table format.

Each row in the table contains data for a particular subscriber. You can search, filter, sort and choose columns to include by clicking a column header icon (to the right of each column label) and selecting Filter, Sort Ascending, Sort Descending or Columns.

You can also click any column header to sort and compare the values that interest you. Right-click on a table cell to Export to Excel or Copy Cell Value.

Investigate a topic by double-clicking a row, which opens the IBM MQ Topic Subscriber Summary display.

All Topic Subscribers Table

 

Broker

The name of the broker.

 

Topic String

The name of the topic string.

 

Subscription ID

When NO, the subscription is removed when the application that created it is closed or disconnected from the queue manager. When YES, the subscription persists even when the creating application is no longer running or has been disconnected. The subscription is reinstated when the queue manager is restarted.

IBM MQ Topic Subscribers Heatmap

View current alert status and performance metrics of all topic subscribers on a specific MQ broker.

Each rectangle in the heatmap represents a different topic subscriber, where the rectangle color indicates the most critical alert state for items associated with that topic subscriber, and the rectangle size represents the tablespace allocation size for the topic subscriber.

Each metric has its own color gradient bar legend that maps values to colors. By default, the Alert Severity metric is shown, which is the current alert severity for items associated with the rectangle. Values range from 0 - 2, as indicated in the color gradient bar:

(2) Red indicates that one or more metrics exceeded their ALARM LEVEL threshold.

(1) Yellow indicates that one or more metrics exceeded their WARNING LEVEL threshold.

(0) Green indicates that no metrics have exceeded their alert thresholds.

Use the Show Broker check-box to include or exclude labels in the heatmap, use the Log Scale check-box to apply log scale, and mouse over a rectangle to see additional metrics. Click a rectangle to drill down on an instance in the IBM MQ Topic Subscriber Summary display.

Fields and Data

 

Topic Subscribers

The number of topic subscribers found by the filter and listed in the heatmap.

 

Show Broker

Select this check box to display the names of the brokers at the top of each rectangle in the heatmap.

 

Log Scale

Select this check box to enable a logarithmic scale. Use Log Scale to see usage correlations for data with a wide range of values. For example, if a minority of your data is on a scale of tens, and a majority of your data is on a scale of thousands, the minority of your data is typically not visible in non-log scale graphs. Log Scale makes data on both scales visible by applying logarithmic values rather than actual values to the data.

 

Auto Scale

Select to enable auto-scaling. When auto-scaling is activated, the color gradient bar's maximum range displays the highest value.

Note: Some metrics auto-scale automatically, even when Auto Scale is not selected.

 

Metric

Choose a metric to view in the display. For details about the data, refer to vendor documentation.

 

 

Alert Severity

The current alert severity for items associated with the rectangle. Values range from 0 - 2, as indicated in the color gradient bar, where 2 is the highest Alert Severity:

(2) Red indicates that one or more metrics exceeded their ALARM LEVEL threshold.

(1) Yellow indicates that one or more metrics exceeded their WARNING LEVEL threshold.

(0) Green indicates that no metrics have exceeded their alert thresholds.

 

 

Alert Count

The total number of critical and warning unacknowledged alerts for items associated with the rectangle. The color gradient bar, populated by the current heatmap, shows 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.

 

 

Rate Message Count

The rate of messages put to the destination specified by the subscription. The color gradient bar, populated by the current heatmap, shows the value/color mapping. The numerical values in the gradient bar range from 0 to the maximum number of published topics in the heatmap. The middle value in the gradient bar indicates the middle value of the range.

 

IBM MQ Topic Subscriber Summary

Use this display to view current alert status and performance metrics for a specifig topic subscriber on a specific MQ broker. Select a broker, a topic string, and a subscription ID from the drop-down menus to view data for the selected topic subscriber. Clicking on the information boxes at the top of the display (such as Message Count and Message Rate) opens the IBM MQ Topic Subscribers Table display, where you can sort and compare the performance values of all topic subscribers.

The trend graph traces the Metric Trends (Message Rate) for the selected topic subscriber. You can specify the time range for the trend graph and view data based on a log scale, which enables visualization on a logarithmic scale and should be used when the range in your data is very broad.

Clicking the Critical/Warning link at the bottom of the display opens the Alerts Table by Component display. You can hover over the trend graph to see the values at a particular time.
