Alerts Overview


Alerts can be configured to trigger based on any Metric.

Metric Sessions

Required Fields

Palette requires filtering by the following fields:

MetricThe data points taken during this metric
PercentileThe percentile aggregation for data points.

Optional Fields

Refer to Metric Filtering to see all available filters.


A trigger is a condition that must be met for an alert to send. A trigger is composed of the following:

  • Aggregation Method
  • Trigger Type
  • Confirmation Period
  • Time Interval

Alert Trigger

Based on your configured query, Palette will aggregate a value over the confirmation period for the current period and then compare it against the previous period.

Aggregation Method

The aggregation method is the method used to aggregate the metric values over the confirmation period. Here’s a list of all available aggregation methods:

SumThe sum of all metric values
AverageThe average of all metric values
MinThe minimum value of all metric values
MaxThe maximum value of all metric values
Point by pointThis will compare each metric value of the current period to the corresponding metric value of the previous period

If there are missing values for a given bucket, Palette will drop them and only take into account valid values.

Trigger Type

There are two types of triggers:

ThresholdThe threshold is a fixed value in ms
PercentageThe percentage calculates a relative value based on the previous time interval.

Palette also allows setting up multiple triggers based on 3 predefined severity levels:

  • Critical
  • Warning
  • Recovery

Confirmation Period

The time period that the trigger is evaluated over. Palette evaluates the specified window every 5 minutes. For example, if you set the confirmation period to 30 minutes, Palette will evaluate the current time period at:

  • 9:00 AM - 9:30 AM
  • 9:05 AM - 9:35 AM
  • 9:10 AM - 9:40 AM
  • and so on…

Time Interval

The time interval is used to determine the two periods of the metric which will be compared against each other. The current period ends at the time the alert is evaluated, while the previous period ends at the time the alert is evaluated minus the confirmation period.

  • current time period
    • start = now - confirmation period
    • end = now
  • previous time period
    • start = now - confirmation period - time interval
    • end = now - confirmation period


Destinations are the external sources that Palette will notify when an alert is triggered. Palette supports the following destinations:

  • Slack - connect your Slack workspace to Palette and choose which channel to notify
  • Email - choose which team members to notify
