Filter By:

The number of producers found on the selected cluster, and that are listed in the All Producers Table.

The name of the cluster.*

The current alert severity.

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

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

Green indicates that no metrics have exceeded their alert thresholds.

The maximum number of messages that can be added to a batch before being sent to the event handler.*

The average per-second number of record sends that are dropped due to buffer exhaustion.*

The fraction of time an appender waits for space allocation.*

The rate of connections being closed.*

The rate of connections being created.*

The rate of input/output operations.*

The percent of time the producer was performing I/O operations while the CPU was idle.*

The age (in seconds) of the current producer metadata being used.*

The average number of outgoing bytes per second.*

The maximum time (in milliseconds) a request was throttled by a broker.*

The average time (in milliseconds) record batches spent in the record accumulator.*

The average per-second number of retried record sends.

The average record size.*

Denotes whether or not the producer is connected.

Fields and Data

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

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.

Select the metric driving the heatmap display. The default is Alert Severity. Each Metric has a color gradient bar that maps values to colors. Mouse-over any rectangle to display the current values of the metrics for the producer. Click on a rectangle to drill-down to the associated Kafka Single Producer Summary display for a detailed view of metrics for that particular producer.

The total number of critical and warning unacknowledged alerts in the adapters. 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 average alert count.

The rate of outgoing bytes (per second). The color gradient bar shows the range of the value/color mapping. ated by the current heatmap, shows the value/color mapping. The numerical values in the gradient bar range from 0 to the defined alert threshold of KafkaProducerOutgoingByteRate. The middle value in the gradient bar indicates the middle value of the range.

When Auto Scale is checked, the numeric values in the color gradient bar show the range of the data being displayed rather than the default values. The middle value changes accordingly to indicate the color of the middle value of the range.

The average amount of time between when a producer is called and when the producer receives a response from the broker. 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 defined alert threshold of KafkaProducerRequestLatency. The middle value in the gradient bar indicates the middle value of the range.

When Auto Scale is checked, the numeric values in the color gradient bar show the range of the data being displayed rather than the default values. The middle value changes accordingly to indicate the color of the middle value of the range.

Select the producer for which you want to show data in the display.

The rate of incoming and outgoing bytes (kilobytes per second).*

The rate of input/output network operations.*

The average batch size sent by the producer, and the maximum number of messages that can be added to a batch before being sent to the event handler.*

Performance

Requests/s -- traces the number of requests per second.

Responses/s -- traces the number of responses per second.

Max Request Latency ms -- traces the maximum request latency (in milliseconds).

Avg Request Latency ms -- traces the average request latency (in milliseconds).

Outgoing KBs/s -- traces the rate of outgoing bytes (kilobytes per second).

Avg IO Wait ms -- traces the average length of time the I/O thread spent waiting for a socket (in milliseconds).

JVM

JVM CPU % -- traces the CPU being used by the JVM.

Max Mem MB -- traces the maximum amount of available heap.

Committed Mem MB -- traces the amount of committed heap memory.

Used Mem MB -- traces the highest amount of heap used.

Live Threads -- traces the number of live threads.

Select a time range from the drop down menu varying from 5 Minutes to Last 7 Days. By default, the time range end point is the current time.

To change the time range, deselect the now toggle, which displays some additional date fields. You can click the left and right arrow buttons to decrease the end time by one time period (the time selected in the Time range drop down) per click, or you can choose the date and time from the associated calendar and clock icons. You can also enter the date and time in the text field using the following format: MMM dd, YYYY HH:MM:ss. For example, Aug 21, 2018 12:24 PM. Click the now toggle to reset the time range end point to the current time.

The highest number of threads running at one time during the current polling period.*

The amount of memory available after garbage collection takes place.
