Docker Containers View

These displays allow you to view the current and historical metrics for all containers in a heatmap or tabular format for one or all hosts, or view the current and historical metrics for a single container. Clicking Docker Containers from the left/navigation menu opens the Docker Containers Table display, which shows a tabular view of all containers and their associated metrics for a particular host. The options available under Docker Containers are:

•

All Containers Heatmap: Opens the Docker Containers Heatmap display, which provides a heatmap view of all containers and their associated metrics for a particular host.

•

Single Container Summary: Opens the Docker Single Container Summary display, which provides additional details and a way to view trending data for a single container for a particular host.

Docker Containers Table

This display allows you to view details in a table format for all containers on a particular host or for all containers on all hosts. You can drill-down and view the details for a particular container in the Docker Single Container Summary display by double-clicking on a row in the resulting table.

Filter By: The display includes these filtering options:
	Host	Select the host for which you want to show data in the display.
Containers		Lists the total number of containers (rows) found using the search parameters.
All Containers Table
	Host	The name of the host.
	Container	The name of the container.
	ID	The absolute container name.
	Alert Level	The current alert status. 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.
	Alert Count	Total number of alerts for the process.
	CPU Usage %	The percentage of CPU used by the container.
	Memory Avg MB	The average amount of memory, in megabytes, that is available to the container.
	Memory Usage MB	Current memory usage by the container, in megabytes, which includes all memory regardless of when it was accessed.
	Memory WS MB	The amount of memory (in megabytes) in the working set, which includes recently accessed memory, dirty memory, and kernel memory.
	Memory RSS MB	The Resident Set Size, which is the amount of anonymous and swap cache memory (including transparent/hugepages), in megabytes.
	Net Bytes In Avg	The average number of incoming bytes per second.
	Net Bytes Out Avg	The average number of outgoing bytes per second.
	Net Packets In Avg	The average number of incoming packets per second.
	Net Packets Out Avg	The average number of outgoing packets per second.
	Expired	When checked, performance data has not been received within the time specified (in seconds) in the Expire Time field in the Duration region in the RTView Configuration Application > (Project Name) > Solution Package Configuration > Docker > DATA STORAGE tab. The Delete Time field (also in the Duration region) allows you to define the amount of time (in seconds) in which the row will be removed from the table if there is no response.
	Timestamp	The date and time the row data was last updated.

Docker Containers Heatmap

Clicking All Containers Heatmap in the left/navigation menu opens the Docker Containers Heatmap, which provides an easy-to-view interface that allows you to quickly identify the current status of each of your containers for each available metric. You can view the containers in the heatmap based on the following metrics: the current alert severity, the current alert count, the percentage of CPU used, and the percentage of memory used. By default, this display shows the heatmap based on the Alert Severity metric.

Each rectangle in the heatmap represents a container. The rectangle color indicates the most critical alert state associated with the container. Choose a different metric to display from the Metric drop-down menu. You can use the Show Hosts check-box to include or exclude labels in the heatmap, and you can mouse over a rectangle to see additional metrics for a container.

Drill-down and investigate an engine by clicking a rectangle in the heatmap to view details in the Docker Single Container Summary display.

Filter:
	Host	Select the host (or All Hosts) for which you want to show data in the heatmap.
Fields and Data:
	Count	Lists the total number of containers (rows) found using the search parameters.
	Show Host	Select this check box to display the names of the containers at the top of each rectangle in the heatmap.
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	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 servers by host, where each rectangle represents a container. Mouse-over any rectangle to display the current values of the metrics for the container. Click on a rectangle to drill-down to the associated Docker Single Container Summary display for a detailed view of metrics for that particular container.
		Alert Severity	The current alert severity. Values range from 0 - 2, as indicated in the color gradient bar, where 2 is the highest 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.
		Alert Count	The total number of critical and warning unacknowledged alerts in the instance. 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.
		CPU Usage %	The percentage of CPU used by the container. 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 DocContainerCpuUsageHigh. 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.
		Memory Usage MB	The current memory usage by the container, in megabytes, which includes all memory regardless of when it was accessed. 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 connections in the heatmap. The middle value in the gradient bar indicates the middle value of the range. The Auto Scale option does not impact this metric.
		Net Avg Bytes In	The net average number of incoming bytes. 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 DocContainerNetBytesInHigh. 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.
		Net Avg Bytes Out	The net average number of outgoing bytes. 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 DocContainerNetBytesOutHigh. 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.

Docker Single Container Summary

Clicking Single Container Summary in the left/navigation menu opens the Docker Single Container Summary display, which provides a view of the current and historical metrics for a single container. You can view the current information pertaining to CPU usage percentage, Memory details, and network data details in the upper portion of the display. Clicking on the information boxes at the top of the display takes you to the Docker Containers Table display, where you can view additional containers data.

The Performance Trends trend graph allows you to view trend data for the CPU percentage, memory used, inbound net kilobytes, and outbound net kilobytes over a selected time range.

Clicking the Critical/Warning link at the bottom of the display opens the Alerts Table by Component display.

Filter By: The display might include these filtering options:
	Host	Select the host for which you want to show data in the display.
	Container	Select the container for which you want to show data in the display.
Fields and Data:
	CPU Usage %	The percentage of CPU used by the container.
	Memory Usage MB	The current memory usage by the container, in megabytes, which includes all memory regardless of when it was accessed.
	Memory WS MB	The amount of memory (in megabytes) in the working set, which includes recently accessed memory, dirty memory, and kernel memory.

	Avg Inbound Network KB	The average number of incoming network kilobytes.
	Avg Outbound Network KB	The average number of outbound network kilobytes.
	Performance Trends Graph	Traces the following: CPU %-- traces percentage of CPU used by the container. Mem Used MB -- traces the current memory usage by the container, in megabytes, which includes all memory regardless of when it was accessed. Inbound Net KB -- traces the average number of incoming kilobytes per second. Outbound Net KB -- traces the average number of outgoing kilobytes per second.
		Log Scale	Select 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.
		Time Settings	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.
