Widget Alerts

Widget Alerts enable you to set up alerts directly on a widget based on a threshold, anomaly detected, or custom condition in your data and have the alert along with results sent via email/webhook/Slack.


Sections

  • Creating a Threshold Widget Alert
  • Creating an Anomaly Detection Widget Alert
  • Creating a Custom Widget Alert
  • Advanced Settings
  • Send alert via Email
  • Send alert via Webhook
  • Send alert via Slack


To get started, navigate to the widget you want to create an alert for and click the Add/Remove Alert Icon. 



Creating a Threshold Widget Alert

  1. Navigate to the widget you want to create an alert for and click the Add/Remove Alert icon
  2. Select Add Alert + to open the Create Alert sidebar 
  3. Select the Threshold tab
  4. Give your Alert a name. This is how it will be displayed in Alerts Management
  5. In Alerts metric dropdown, select the field you want to set an alert on
  6. Choose the the threshold type (i.e. >, >=, =, <=, <)
  7. In the Threshold box, enter the value that will trigger the alert
  8. See section below for Advanced Settings
  9. Select a Send Alert via action to configure alert to be sent via email/webhook/Slack



Creating an Anomaly Detection Widget Alert

Time-series anomaly detection is used to identify unusual patterns that do not conform to expected behavior, called outliers. This alert notifies you when such anomalies are detected within your data.


  1. Navigate to the widget you want to create an alert for and click the Add/Remove Alert Icon
  2. Select Add Alert + to open the Create Alert sidebar 
  3. Select the Anomaly Detection (Beta) tab
  4. Give your Alert a name. This is how it will be displayed in Alerts Management
  5. In Alerts metric dropdown, select the field you want to set an alert on
  6. Set the Anomaly Detection Threshold (default: 50). The threshold/band width determines the range of expected values. Values outside of the threshold are considered anomalies. 
  7. Select the Date/Time Dimension - this is the time series feature of the selected dataset, typically used as the x-axis of time-series charts
  8. Select a Dimension to detect anomalies across other fields in your dataset
  9. Use the Preview button to preview the anomaly detection model which is trained and applied to the data
  10. Select the type of dimension from Dimension drop-down to see the specific values
  11. See section below for Advanced Settings
  12. Select a Send Alert via action to configure alert to be sent via email/webhook/Slack



Creating a Custom Widget Alert

  1. Navigate to the widget you want to create an alert for and click the Add/Remove Alert Icon
  2. Select Add Alert + to open the Create Alert sidebar 
  3. Select the Custom tab
  4. Give your Alert a name. This is how it will be displayed in Alerts Management
  5. In the Cloud9QL condition editor, enter a custom alert condition syntax. For example, to be notified when the stock Close price exceeds the 50-period moving average, use the syntax:
  6. The custom condition you?ve specified will trigger the alert
  7. See section below for Advanced Settings
  8. Select a Send Alert via action to configure alert to be sent via email/webhook/Slack


Advanced Settings

These are additional options to configure your Alert. Check the Advanced Settings box to expand the menu.



  • Generate Alert if no data is detected: Check this box to raise the alert if no data is returned from the alert condition
  • Attach conditional data as part of the alert: Check this box to attach the underlying dataset after the alert condition is applied as part of the alert
  • Attach another dataset on trigger: Check this box to attach a separate dataset when the condition is triggered. For example, if an alert is triggered for total Users crossing a threshold, but you need the data sent/attached to be from a list of Users from a separate dataset/query. Cloud9QL can be applied on that dataset to optionally manipulate the results
  • Enable realtime alerts: Check this box to trigger the alert every time the dataset is updated. Not available for direct datasets. If users want to receive alerts based on time period, leave the box unchecked and specify the Run Every box with a value with minutes, hours, days, or months option. Mention the timezone in which you want the alert to trigger.
  • Skip Alert if data is same as last alert: Check this box to skip this alert If the data is the same as the last alert. Useful to avoid repetitive alerts


Send alert via

This section will walk you through setting up Alert notifications for Widget Alerts.


Email

Email Alerts allows you to send the alert via email along with a CSV attachment of results to a list of recipients. 



To set up an Email Alert:

  1. Under Send alert via, select the Email tab, then click Setup
  2. Enter the Email Subject that will be displayed
  3. In the Email From section, enter the email address that the email will be sent from (support@knowi.com by default). This address will appear as the sender of the email when received in your inbox
  4. Enter the email address of the recipient(s). Comma separated for multiple recipients
  5. Enter the Email Body. (Optional) Write custom HTML to customize the email template
  6. Attach Full Dataset as CSV (optional): Check this box to attach the full underlying dataset as a CSV to the email
  7. Attach Results after Cloud9QL as CSV (optional): Check this box to attach the results after the trigger condition as a CSV to the email
  8. Click Save Settings
  9. Click Test Run (optional) to send a test email alert to the chosen recipient(s)
  10. Once configuration is complete, click Save Alert
  11. You can add a new Alert or edit an existing one by clicking the Alert Icon in the widget


Webhook

Webhook Alerts allow you to send an alert directly to your application (or third party applications). When the condition is triggered, we'll send a POST request with a JSON payload of the data, which you can use to drive actions within your application. 

The data in the POST will be a JSON formatted dataset of either the full raw dataset for which the alert is generated, or the dataset after Cloud9QL which triggered the alert. Additionally, you can use Cloud9QL to make any adjustments to the data before posting.



To set up a Webhook Alert:

  1. Under Send alert via, select the Webhook tab, then click Setup
  2. Click Add New Webhook. This opens up the Create new webhook sidebar
  3. Under URL to Invoke, enter the endpoint in your application that can accept a post request with JSON (Array of Objects). For example: https://somehost.com/someEndpoint
  4. Enter an Authentication URL, In cases where you need to call an authentication endpoint first to obtain a token, which is then passed into the actual POST request, use the Authentication URL along with any Authentication headers. This will invoke a separate POST call to obtain an auth token first, which can be subsequently passed as a token into the Headers section:
    • Authorization: Bearer {access token}
  5. Under Headers, enter any optional authentication related headers. One header per line. For example:
  6. Under Auth Headers, enter any optional authentication related headers. One header per line. For example:

  7. Under Cloud9QL filter before POST, leave empty if you want to send the full results of the Alert. Otherwise, enter any additional manipulation to the data using C9QL before sending to the endpoint. For example, if you only want to send a subset of the most recent close prices which are over 160 and order them by date descending, enter:
    • select * where close > 160 order by date desc limit 10;
  8. Check the box Use full dataset into POST to send the whole dataset. If left unchecked, then the results after Cloud9QL which triggered data will be used
  9. Click Save Settings
  10. Click Test Run (optional) to send a test webhook alert to the chosen application. Here?s an example of the results in JSON form:
  11. Once configuration is complete, click Save Alert
  12. You can add a new Alert or edit an existing one by clicking the Alert Icon in the widget


Slack

Slack integration allows you to trigger actions in your Slack channel(s) for a given condition triggered by an alert. When the condition is triggered, we'll send a message to a predefined channel(s) including the attachment of full data or conditional data depending on the options selected.
