Filtering Explore

Explore provides the ability to filter your view so you can focus on specific entities and sections of your system.

Create filters

  1. To filter Explore click the filter icon in the left-hand navigation menu. You can click the icon to toggle the visibility of the menu.
    Explore

  2. Once clicked the filter menu appears below:
    Explore

The Filter menu allows you to select a saved filter or write a new one. If you have any saved filters they are available in the dropdown menu Filter. The default value is None Selected. The Clear All button is available to clear any filters that are already applied.

  1. To create a new filter click in the Enter a key value pair to create a filter input area. A dropdown will appear showing you available keys you can filter by. You may only provide a value without a key.
    Explore

  2. Enter or select the keys you want to filter by then click Apply. Filters of the same key behave as an OR condition and different keys behave as an AND condition.
    Explore

The Dashboard and Explore menu will refresh with your filters applied.

Negation

You can apply the filter as an exclusion or negation so the filter acts as a not or bang !. This way the filter will return results that don't have those values. Simply click the prohibition or no sign to set. The filter will get a red border when set to exclude. You may manually add an exclamation or bang ! to the input area before selecting your filter. For example, !_key=value.

Saving filters

You can save filters so they are applied every time you explore the same Dashboards. To save, click the three-vertical dots icon and then click Save.
Explore

A pop up window is shown where you need to provide the filter a name. This name is what you'll see in the Filter dropdown menu.
Explore

We have named the filter "primary" in the above image. Once done click Save. When opening Explore you'll now see the primary filter as an option in the Filter menu.
Explore

Updating, Deleting, Saving filters as default

Saved filters can be applied as a default filter, edited, or deleted.

  • A default filter is applied every time you open Explore.
  • The update option is available if you edit a saved filter.
  • A deleted filter is not recoverable.
Explore

Remove Default filter

The default filter is displayed in the Filter dropdown menu with a Default label. Select the Remove default text link to clear your set default filter.
Explore

Linking to entities in Explore

Use the link button to the right of the Dashboard title in Explore to copy the link to your specific entity view in the dashboard. This is related to Stack Linking.
Explore

You can create a URL to a specific entity in Explore.

Syntax

https://<endpoint>/ui/#/explore/[@<startMs>,<endMs>]@topology=<topologyId>@<entityId>,<entityTypeId>,<entityName>[@<entityId>,<entityTypeId>,<entityName>][@filters@<negation>:<filterValue>[:<filter>],<negation2>:<filterValue2>[:<filter2>] ...]@selectedDashboardId@<dashboardId>

Required:

  • <endpoint> is your Sumo Logic service endpoint. See Sumo Logic Endpoints and Firewall Security for the endpoint URLs.
  • <entityKey> is the type of entity you want to explore, such as cluster, deployment, service, node, account, region, namespace, or pod.
  • <entityValue> is the value of the entity to explore.

Optional arguments:

  • <start> is the start of your dashboard time range in milliseconds since epoch.
  • <end> is the end of your dashboard time range in milliseconds since epoch.

Filters:

  • <filterValue> is the value of a key you want to filter.
  • <filter> (optional) is the metadata key you want to apply as a filter to explore. You do not have to provide a filter, you may only provide a filterValue.
  • <negation> set as 0 to apply your filters or 1 to treat the filters as an exclusion. Think of using 1 as using a not or ! bang, so the filter will return results that don't have those values. This is an example:
https://<endpoint>/ui/#//explore/@1628023955694,1628024855694@topology=0000000000000041@cluster=kubernetes@filters@1:cl-tracing-training:_collector,0:kubernetes:_origin

Dashboard:

  • <dashboardId> is the unique identifier of the Dashboard.

Example

Let’s create a URL to open Explore on the primary-eks cluster, kube-system namespace, and metrics-server service.

The custom URL that launches this log query in the Sumo Logic Search page would be similar to the following. The exact URL would depend on your Sumo Logic account endpoint, as listed in Sumo Logic Endpoints and Firewall Security.

https://service.us2.sumologic.com/ui/#/explore/@cluster=primary-eks@namespace=kube-system@service=metrics-server

Using milliseconds as this time range: 09/26/2020 to 09/29/2020 10:33:10.282 AM GMT-04:00 DST

https://service.us2.sumologic.com/ui/#/explore/@1601092800000,1601389990282@cluster=primary-eks@namespace=kube-system@service=metrics-server

Troubleshooting with Explore

Explore navigation capabilities allow you to quickly locate the object that needs debugging in a physical stack. This section walks you through a high-level troubleshooting scenario to illustrate the possibilities.

micro lesson

Step 1: Analyzing the cluster

We suspect there's a problem with a Kubernetes cluster but aren't sure where, so we start by analyzing the Cluster Overview dashboard. Everything that is running on the cluster is shown on this dashboard. The Terminated and Waiting by Namespace panel allows us to easily comprehend the failure states the namespaces are in. Here we can easily see if there are configuration issues or overall administration issues that need to be addressed.
Explore

Step 2: Exploring a namespace

To further pinpoint the problem with our cluster, we investigated the namespace by selecting kube-system in the navigation panel and switching to the Namespace Overview dashboard. This dashboard provides information on pods running in the deployment, failed pods, errors, CPU and memory usage, file system usage, terminated and waiting pods and containers. In this example, we're focusing on the CPU and memory usage panels of the dashboard in our attempt to find out where our application is running into problems.
Explore

Step 3: Drilling down into a pod

Once we've determined which pod is having problems, we can drill down into the pod for more granular data. For example, you can select the Details icon for a panel to view that data in a search. Or, you can review the actual logs in the Log Stream panel.
