Use navigators in Splunk Infrastructure Monitoring
Use a navigator in Splunk Infrastructure Monitoring
View all navigators
To see all navigators, select Infrastructure from the Splunk Observability Cloud home page.
On the Infrastructure Monitoring landing page, each card represents a navigator, corresponding to the services you monitor in Splunk Observability Cloud. A navigator card shows a count of instances in the population and highlights critical alerts linked to that population. Select the navigator card to open the navigator.
Drill down into the detail view of an instance
The detail view of an instance displays additional information about the instance. For example, if you navigate to the detail view for a host instance, you can see system metrics information in the built-in dashboard with charts. You can also find various properties of the host, processes running on the host, and so on on the Properties sidebar.
In heat map view, select a square to drill down into the detail view of that instance. In table view, select the instance ID of an instance to drill down into the detail view that instance.
As you drill down into a single instance, you can use the breadcrumb trail to switch to the detail view of another instance or to return to the navigator view.
Use the Dashboard section
The Dashboard section contains built-in dashboards that provide access to detailed information about the instances displayed.
Dashboards in navigators are read‑only, so you can’t directly make any changes to them. However, you can clone a built-in dashboard to make changes to the clone, or download a built-in dashboard. As an admin, you can also add or remove custom dashboards, and hide any built-in dashboards that you don’t use.
To learn more, see Clone a built-in dashboard in a navigator and Export a built-in dashboard in a navigator in the Built-in dashboards documentation.
If you have only the public cloud service and the Smart Agent configured, some charts in the built-in dashboards for Amazon EC2, GCP Compute Engine, and Azure Virtual Machines instances display no data.
If you have only the public cloud service configured, you can see all the cards representing the services where data come from, but some charts in the built-in dashboards for Amazon EC2, GCP Compute Engine, and Azure Virtual Machines instances display no data.
If you have only Smart Agent configured, Amazon EC2, GCP Compute Engine, and Azure Virtual Machines instance navigators aren’t available.
Add filter
Select Add Filter to create a filter and view a specific slice of your environment based on dimensions or properties you specify. Filtering is particularly useful for viewing only the instances running a specific service, or in a particular availability zone.
Filters that you apply to your host instances also filter dependencies in the navigator sidebar. To learn more about the navigator sidebar, see View dependencies in the navigator sidebar in the same topic.
Customize time range
By default, you see data from the last three hours. You can use the time picker to select a new time range. When you select a new time range, the navigator updates to show the status of instances during that time.
If the time between the end and start dates of your selected time range is more than seven days, the navigator might take longer to respond.
Color by
Use the Color by drop-down menu in the control bar to specify the metric you want to use to color the squares. Square color values vary depending on which Color‑by criteria you choose.
For example, if you select CPU Utilization, colors range from green (lowest 20% of values among all instances) to red (highest 20% of values among all instances). For many metrics, red indicates intensity of performance rather than a problem situation.
White squares indicate instances that do not emit values for the specified metric.
Black squares indicate instances considered "dead" by Infrastructure Monitoring because they do not emit values for a specified period of time.
You can specify settings related to these non-emitting instances by selecting Navigator Settings from the Actions menu (⋯). When the instances begin emitting values again, the squares are recolored accordingly.
Group by
Use the Group by drop-down menu in the control bar to partition instances by the selected dimension or property. As you hover over or select the different options in the list, the instances immediately rearrange themselves in the navigator. This feature lets you do a hierarchical grouping of up to two levels.
In some cases, you might see an option titled "n/a" in the drop-down menu. This group contains instances that don’t have a value for the Group‑by dimension or property you specify.
When you specify a Group‑by field, you can select a group name to filter the navigator to only show the instances in that group. The breadcrumb trail updates to indicate your selected group.
Find outliers
Apply outlier detection to identify instance outliers in your data. Outliers are denoted by the color red based on values of the Color by metric.
Outlier detection can be determined by one of two strategies that are common in data analysis:
Deviation from population mean
Highlight instances with values significantly higher than the average value of other instances. This strategy tends to highlight only those instances with the most extreme values, and provides meaningful results only when you have a large number of instances (15 or more).
Deviation from the population median
Highlight instances with values significantly higher than the median value of other instances. If there are relatively small differences in value among the majority of instances, this strategy tends to highlight any instance which is not part of this majority.
For example, if instances are grouped by the service that they are running, colored by cpu.utilization
, and outlier detection is enabled, then instances that use significantly more CPU than their others are highlighted in red. You can then investigate those specific instances to determine why they are behaving differently.
While both outlier strategies highlight instances that are behaving differently from others, if the population has two groups of outliers, such as when most instances are running at 20% CPU utilization but three are running at 60% one is running at 80%, deviation from mean finds the greater outlier (instances running at 80%), while the deviation from median can typically identify both groups. You can always switch from one strategy to another to find the one that works best for your specific environment.
The Find Outliers feature also provides a population selector that lets you restrict the comparison population to only those instances that have similar characteristics (as defined by the Group By dimension). For example, you might not want to compare a server against others that are running different software. It is more relevant to determine outliers among servers providing the same service. Grouping instances by the service that they run and using that as your population basis ensures that instances are compared only with their peers to determine if they behave atypically.
Use metric classes
By default, some navigators display a multi-metric table view with a subset of metrics and KPIs used to monitor the performance of your instances. You can customize the multi-metric table view by using predefined metric classes, which are groupings of related metrics and KPIs useful for troubleshooting specific aspects of your deployment.
If predefined metric classes are available for the navigator, you can use the Metric class drop-down menu in the table view to customize your view.
The Metric class drop-down menu only appears if the navigator has predefined metric classes. For more information on the available predefined metric classes, see Predefined metric classes.
View global data links
By default, Splunk Infrastructure Monitoring automatically creates and displays global data links in the navigator table view and Metadata tab.
To configure additional global data links to appear in the Metadata tab, see Link metadata to related resources using global data links.
Best practice
To get the most out of the navigator sidebar, configure the services you want to track in the Splunk Distribution of OpenTelemetry Collector configuration file as service.name
values under extraDimensions
. By configuring service.name
values, you can see more details about your data, such as which individual services are running on specific host instances.
Example
For example, the redis-cart
service is included in this Splunk Distribution of OpenTelemetry Collector configuration.
receiver_creator:
receivers:
smartagent/redis:
rule: type == "pod" && name contains "redis"
config:
type: collectd/redis
host: redis-cart
port: 6379
extraDimensions:
service.name: redis-cart
For more information on the Splunk Distribution of OpenTelemetry Collector configuration, see Collector components.
