Table: kubernetes_event - Query Kubernetes Events using SQL

Kubernetes Events are objects that provide insight into what is happening inside a cluster, such as what decisions were made by scheduler or why some pods were evicted from the node. Events are a resource type in Kubernetes that are automatically created when certain situations occur, and they give developers a tool to understand the activity of the system.

Table Usage Guide

The kubernetes_event table provides insights into events within a Kubernetes system. As a DevOps engineer or system administrator, explore event-specific details through this table, including the involved object, source, message, and related metadata. Utilize it to monitor system behaviors, troubleshoot issues, and understand the state changes in the workloads running on the cluster.

Examples

Basic Info

Explore the recent events in your Kubernetes environment to understand the status and health of your objects. This query can help you identify any issues or anomalies, providing valuable insights for troubleshooting and maintenance.

select
  namespace,
  last_timestamp,
  type,
  reason,
  concat(
    involved_object ->> 'kind',
    '/',
    involved_object ->> 'name'
  ) as object,
  message
from
  kubernetes_event;

select
  namespace,
  last_timestamp,
  type,
  reason,
  involved_object || '/' || involved_object as object,
  message
from
  kubernetes_event;

List warning events by last timestamp

Identify instances where warning events have occurred in your Kubernetes environment. This query is useful for tracking and understanding the chronology of these events to manage and troubleshoot issues effectively.

select
  namespace,
  last_timestamp,
  type,
  reason,
  concat(
    involved_object ->> 'kind',
    '/',
    involved_object ->> 'name'
  ) as object,
  message
from
  kubernetes_event
where
  type = 'Warning'
order by
  namespace,
  last_timestamp;

select
  namespace,
  last_timestamp,
  type,
  reason,
  involved_object || '/' || involved_object as object,
  message
from
  kubernetes_event
where
  type = 'Warning'
order by
  namespace,
  last_timestamp;

List manifest resources

Explore which Kubernetes events have a defined path to gain insights into the health and status of your Kubernetes resources. This can help identify any potential issues or anomalies within your system.

select
  namespace,
  type,
  reason,
  concat(
    involved_object ->> 'kind',
    '/',
    involved_object ->> 'name'
  ) as object,
  message,
  path
from
  kubernetes_event
where
  path is not null;

select
  namespace,
  type,
  reason,
  involved_object || '/' || involved_object as object,
  message,
  path
from
  kubernetes_event
where
  path is not null;

Schema for kubernetes_event

Name	Type	Description
_ctx	jsonb	Steampipe context in JSON form, e.g. connection_name.
action	text	What action was taken/failed with the regarding object.
annotations	jsonb	Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata.
context_name	text	Kubectl config context name.
count	bigint	The number of times this event has occurred.
creation_timestamp	timestamp with time zone	CreationTimestamp is a timestamp representing the server time when this object was created.
deletion_grace_period_seconds	bigint	Number of seconds allowed for this object to gracefully terminate before it will be removed from the system. Only set when deletionTimestamp is also set.
deletion_timestamp	timestamp with time zone	DeletionTimestamp is RFC 3339 date and time at which this resource will be deleted.
end_line	bigint	The path to the manifest file.
event_time	timestamp with time zone	Time when this event was first observed.
finalizers	jsonb	Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed.
first_timestamp	timestamp with time zone	The time at which the event was first recorded.
generate_name	text	GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided.
generation	bigint	A sequence number representing a specific generation of the desired state.
involved_object	jsonb	The object that this event is about.
labels	jsonb	Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services.
last_timestamp	timestamp with time zone	Time when this event was last observed.
message	text	A description of the status of this operation.
name	text	Name of the object. Name must be unique within a namespace.
namespace	text	Namespace defines the space within which each name must be unique.
owner_references	jsonb	List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.
path	text	The path to the manifest file.
reason	text	The reason the transition into the object's current status.
related	jsonb	Optional secondary object for more complex actions.
reporting_component	text	Name of the controller that emitted this event.
reporting_instance	text	ID of the controller instance.
resource_version	text	An opaque value that represents the internal version of this object that can be used by clients to determine when objects have changed.
series	jsonb	Data about the event series this event represents.
source	jsonb	The component reporting this event.
source_type	text	The source of the resource. Possible values are: deployed and manifest. If the resource is fetched from the spec file the value will be manifest.
start_line	bigint	The path to the manifest file.
type	text	Type of this event (Normal, Warning), new types could be added in the future.
uid	text	UID is the unique in time and space value for this object.

Export

This table is available as a standalone Exporter CLI. Steampipe exporters are stand-alone binaries that allow you to extract data using Steampipe plugins without a database.

You can download the tarball for your platform from the Releases page, but it is simplest to install them with the steampipe_export_installer.sh script:

/bin/sh -c "$(curl -fsSL https://steampipe.io/install/export.sh)" -- kubernetes

You can pass the configuration to the command with the --config argument:

steampipe_export_kubernetes --config '<your_config>' kubernetes_event
