Configuring webhook NQL conditions

Write a query for the NQL conditions field of a webhook using:

NQL tables and NQL properties supported by Webhooks.
NQL operators supported by Webhooks.

NQL tables supported by Webhooks

Find below the NQL tables supported by Webhooks in the format of <namespace>.<table>.

The system displays an error message when saving a webhook configuration with unsupported NQL objects in the NQL conditions field, even for valid syntaxes.

Jump to the end of the page for examples of NQL conditions for Webhooks.

NQL objects supported by Webhooks

NQL properties supported by Webhooks

When writing the query in the NQL conditions field from the webhook configuration page, the system displays the supported NQL properties from the NQL objects listed above. See the image below.

Using unsupported NQL table properties results in system errors, even for valid syntaxes.

NQL operators supported by Webhooks

Not all NQL operators are available to the customer. When working with punctual events, use the following subset of NQL operators.

NQL Operator Type Available in Webhook Mandatory

NQL Operator	Type	Available in Webhook	Mandatory
`where`	selection	Yes	No
`list`	projection	Yes	Yes, at least once.
`and`	filtering	Yes	No
`or`	filtering	Yes	No
`contains`	filtering	Yes	No
`in`	filtering	Yes	No

where

selection

Yes

list

projection

Yes, at least once.

and

filtering

or

contains

You must add every NQL field you use as a placeholder in the webhook Resource or Payload to the list clause.

Even if you do not use any placeholders, still you must add one NQL field to the list clause.

Valid NQL conditions examples for alert-related webhooks

Some of the following valid NQL query examples assume you previously defined the associated alerts. Refer to the Getting started with Alerts documentation for more information.

Valid NQL example.1 - Trigger a webhook when a monitor named “(…)” triggers an alert, and when the condition on a specific web application is met.

alert.alerts
| where monitor.tags contains "web-applications"
| where alert.context contains "*Salesforce*" or alert.context contains "*Microsoft*"
| list alert.monitor.name, alert.status, monitor.tags, alert.context, trigger_time, recovery_time, alert.monitor.thresholds, monitor.priority, alert.trigger_values, alert.trigger_reference_value, alert.recovery_values, alert.context, device_view_link , issue_view_link

Valid NQL example.2 - Trigger a webhook when a monitor named “MS Teams crashes in the last 24 hours" triggers an alert.

alert.alerts
| where monitor.nql_id == "#ms_teams_crashes_in_the_last_24_hours"
| list alert.context

Valid NQL example.3 - Trigger a webhook when a monitor with high priority triggers an alert.

alert.alerts
| where monitor.priority == high
| list alert.context

Valid NQL example.4 - Trigger a Webhook when a monitor named “MS Teams crashes in the last 24 hours" or “Poor video quality for computers" triggers an alert.

alert.alerts
| where monitor.name == "MS Teams crashes in the last 24 hours" or monitor.name == "Poor video quality for computers"
| list alert.context

Valid NQL example.5 - Trigger a Webhook when a monitor with high priority or monitor named “MS Teams crashes for SD", and a tag that contains “servicenow" triggers an alert.

alert.alerts
| where monitor.priority == high or monitor.name == "MS Teams crashes for SD" and monitor.tags contains "servicenow"
| list alert.context

Other valid NQL conditions examples for webhooks

Valid NQL example.6 - Filter the device boots that are equal to fast_startup and when the duration is greater than 200 seconds.

device_performance.boots
| where type == fast_startup and duration > 200s
| list device_performance.boot.type, device_performance.boot.duration

Valid NQL example.7 - Filter the device crashes by error code 335 or 49 that refer to a timeout situation.

device_performance.system_crashes
| where error_code == 335 or error_code == 49 and label in ["TIMEOUT"]
| list device_performance.system_crash.error_code

Valid NQL example.8 - Filter all the execution crashes for the binary zoom.exe that have crashed on start more than 5 times.

execution.crashes
| where binary_path in ["zoom.exe"] and number_of_crashes >= 5 and crash_on_start == true
| list execution.crash.number_of_crashes

Valid NQL example.9 - Filter remote actions by nql_id and completed without a status [expired , failure , cancelled ].

remote_action.executions
| where remote_action.nql_id == "#update_binary" and status in [expired , failure , cancelled ]
| list remote_action.execution.outputs

Valid NQL example.10 - List answers, state, and details of a specific campaign.

campaign.responses 
| where campaign.name == "campaign name" 
| list answers , state , state_details

Invalid NQL conditions for webhooks and common mistakes

Some of the following invalid NQL query examples assume you previously defined the associated alerts. Refer to the Getting started with Alerts documentation for more information.

Invalid NQL example.1 - Unsupported NQL tables, missing the list operator and wrong usage of the in operator.

device_performance.system_crashes
| where error_code == 335 or error_code == 49 and label in [*TIMEOUT*]

Invalid NQL example.2 - Unavailable properties and the wrong usage of the in operator.

alert.alerts
| where trigger_time == "2021-10-23" and monitor.tags in ["*Logitech*"]
| list alert.context

Invalid NQL example.3 - Unavailable operators.

devices
| with alert.alerts during past 7d 
| summarize c1 = count() by sid

Invalid NQL example.4 - Unsupported NQL tables.

devices
| where device.operating_system.platform == Windows
| list device.name

Invalid NQL example.5 - Unsupported NQL operators.

devices
| with execution.crashes
| summarize count=count() by operating_system.name

Invalid NQL example.6 - Wrong value when comparing enums.

device_performance.BoOTS | where type == FULLboot
device_PErformance.BoOTS | where type == FULLboot
device_PErformance.BoOTS | where TyPe == FULLboot
device_performance . boots | where type == FullbooT
