Send alert notifications to Splunk platform using Splunk Observability Cloud 🔗

You can configure Splunk Observability Cloud to automatically send alert notifications to Splunk platform when a condition triggers the detector and when a clear condition clears the alert.

Note

To send Splunk Observability Cloud alert notifications to Splunk platform, complete the following configuration tasks:

Step 1: Create a Splunk platform integration in Splunk Observability Cloud 🔗

  1. Log in to Splunk Observability Cloud.

  2. Open the Splunk platform guided setup . Alternatively, you can navigate to the guided setup on your own:

    1. In the navigation menu, select Data Management.

    2. Go to the Available integrations tab, or select Add Integration in the Deployed integrations tab.

    3. In the integration filter menu, select All.

    4. In the Search field, search for Splunk platform, and select it.

    5. Select New Integration to display the configuration options.

  3. On the Summary page, select Next.

  4. On the Configure connection page, enter information into the following fields:

    Field

    Description

    Name

    Give your integration a unique and descriptive name. For information about the downstream use of this name, see About naming your integrations.

    URL

    Enter the HTTP Event Collector (HEC) URI for your Splunk platform instance. To learn more, see the Send data to HTTP Event Collector section in the Documentation for Splunk Cloud Platform.

    HEC token

    Enter the HTTP Event Collector token that allows access to your Splunk platform instance. To learn more, see Set up and use HTTP Event Collector in Splunk Web .

    Note

    Splunk Observability Cloud doesn’t support HEC indexer acknowledgement. To use the Splunk platform integration, don’t activate indexer acknowledgement for HEC token in your Splunk Enterprise instance.

  5. Select Next.

  6. On the Customize message page, you see the default template for a Splunk platform integration. You can customize your payload to make sure responders have the context needed to resolve the issues. To learn more, see Supported variables for Splunk platform integration custom payload.

  7. Select Next.

  8. Review your integration and select Save.

Step 2: Add a Splunk platform integration as a detector alert recipient in Observability Cloud 🔗

To add a Splunk platform integration as a detector alert recipient in Splunk Observability Cloud:

  1. Create or edit a detector that you want to configure to send alert notifications using your Splunk platform integration.

    For more information about working with detectors, see Create detectors to trigger alerts and Subscribe to alerts using the Detector menu.

  2. In the Alert recipients step, select Add Recipient.

  3. Select Splunk platform and then select the name of the Splunk platform integration you want to use to send alert notifications. This is the integration name you created in Step 1: Create a Splunk platform integration in Splunk Observability Cloud.

  4. Activate and save the detector.

Splunk Observability Cloud sends an alert notification to Splunk platform when the detector triggers or clears an alert.

Supported variables for Splunk platform integration custom payload 🔗

The following table shows the full list of variables for customization.

Note

  • Unless otherwise indicated in the description, all variables are of type string.

  • When a variable is optional, it means it’s not always available. If you use an optional variable that isn’t available in the present conditions to construct your payload, Handlebars converts it to an empty string.

Variable

Description

detector

Name of the detector.

detectorUrl

URL of the detector, which includes a parameter to select this specific incident.

detectorId

ID of the detector.

description

(Optional) Description of the rule for the detector.

dimensions

A map of the dimensions in the input MTS.

imageUrl

(Optional) URL of the alert preview image.

incidentId

Unique identifier for this alert notification.

eventType

Unique identifier for the version of the detector that sent the notification.

rule

Name of the detector rule that triggered the alert.

severity

Severity level of the rule determined by Splunk Observability Cloud. Use this variable in your custom payload.

runbookUrl

Runbook URL specified in this rule.

tip

Tip specified in this rule.

messageTitle

Notification title for this rule.

messageBody

Notification message for this rule.

detectOnCondition

(Optional) Criteria for metric data and detection criteria for the detector rule, written in SignalFlow format.

detectOffCondition

(Optional) Clear metric data and detection criteria in this rule, in SignalFlow format.

status

Status of the incident, kept for backwards compatibility. Use statusExtended for more detailed information. Valid values include:

  • anomalous: the alert is firing because the detect conditions are met.

  • ok: the alert is cleared because the detect conditions are no longer met or the clear conditions, if any, are met.

statusExtended

New variable for status of the incident. Use in place of status. Valid values include:

  • anomalous: the alert is firing because the detect conditions are met.

  • ok: the alert is cleared because the detect conditions are no longer met or the clear conditions, if any, are met.

  • manually resolved: a user resolves the alert through the UI or the API.

  • stopped: the detector that triggered the alert is edited or deleted.

timestamp

Time the event occurred, in ISO 8601 format.

inputs

Map of the inputs involved in this rule. This variable is of type array. For more information, see inputs array.

sf_schema

The schema version for this event. The value is always set to 2.

orgId

The organization ID of the Splunk Observability Cloud org where the alert is coming from.

originatingMetric

Name of the metric that triggered the alert.

src

The source of the alert, as defined by the following dimensions. The first dimension value available is set as the source of the alert.

  • k8s.pod.name

  • k8s.cluster.name

  • k8s.node.name

  • k8s.container.name

  • host

  • host.name

  • aws_arn

  • gcp_standard_id

  • azure_resource_id

inputs array 🔗

Each object in the inputs array is named after the program variable it’s bound to. If an object isn’t bound to a program variable, it uses a name like _S0, _S1, and so on.

Each input object contains the following elements:

Element

Description

key

(Optional) Map of the dimensions of the input signal. This element might be empty if there are no dimensions; for example, if the input was a static value and not a comparison against scalar values.

value

Value of the input when the alert triggered or when it cleared.

fragment

(Optional) This is the fragment of the SignalFlow program that represents the input. This element might not be present for some detectors or for static, anonymous inputs.

Helper functions 🔗

Apart from using template variables to customize your payload, you can also use the following helper functions to make sure the right value is set on the outgoing alert.

Function

Description

Examples

coalesce

Returns the first value that is not empty. You can use this function to specify the desired order of dimensions for the src variable.
{{{coalesce dimensions.host dimensions.aws_arn ‘No ID Found!’}}}
This example sets dimensions.host on the alert if it is present, dimensions.aws_arn as a second option, and the string “No ID Found!” if neither host nor AWS ID is present.

severityDecoder

Returns 2 if the status variable is ok. Otherwise, the function checks and decodes the severity variable:

  • 1: Info

  • 3: Warning

  • 4: Minor

  • 5: Major

  • 6: Critical

  • empty: Unknown severity
{{{severityDecoder ok='ok' Major='not_ok' default='empty'}}}
This example overrides the default return values and customizes them.

encodeString

Escapes quote and newline characters in a string.

{{{encodeString messageTitle}}}

notEmpty

Adds text to a payload only if the value specified is not empty map. This function only works with the inputs and dimensions variables.
This example only prints if dimensions is not empty: {{#notEmpty dimensions}}
{{/notEmpty}}

json

Converts a string to a raw JSON value. Use this function to turn text from a detector into a JSON payload that can be evaluated in third-party integrations.

{{{json dimensions}}}

substring

Returns a new character sequence that is a subsequence of this sequence. The subsequence starts with the character at the specified index and ends with the character at the second to last index.
{{substring var 1}}
{{substring var 1 3}}

abbreviate

Truncates a string if it is longer than the specified number of characters. Minimum abbreviation width is 4.

{{abbreviate long_str 5}}

replace

Replaces each substring of this string that matches the literal target sequence with the specified literal replacement sequence.

{{replace abbreviated '...' ''}}

eq

Checks if two elements are equal.
{{#eq a b}}yes{{else}}no{{/eq}}
{{#eq a 2}}yes{{else}}no{{/eq}}
