Task configuration options

This page documents an earlier version of InfluxDB. InfluxDB v2.7 is the latest stable version. View this page in the v2.7 documentation.

Task options define specific information about a task. They are set in a Flux script or in the InfluxDB user interface (UI). The following task options are available:

• name
• every
• cron
• offset

every and cron are mutually exclusive, but at least one is required.

name

The name of the task. Required.

Data type: String

In Flux:

option task = {
    name: "taskName",
    // ...
}

every

The interval at which the task runs. This option also determines when the task first starts to run, depending on the specified time (in duration literal).

Data type: Duration

For example, if you save or schedule a task at 2:30 and run the task every hour (1h):

option task = {name: "aggregation", every: 1h}

The task first executes at 3:00pm, and subsequently every hour after that.

In Flux:

option task = {
    // ...
    every: 1h,
}

In the InfluxDB UI, use the Interval field to set this option.

cron

The cron expression that defines the schedule on which the task runs. Cron scheduling is based on system time.

Data type: String

In Flux:

option task = {
    // ...
    cron: "0 * * * *",
}

offset

Delays the execution of the task but preserves the original time range. For example, if a task is to run on the hour, a 10m offset will delay it to 10 minutes after the hour, but all time ranges defined in the task are relative to the specified execution time. A common use case is offsetting execution to account for data that may arrive late.

Data type: Duration

In Flux:

option task = {
    // ...
    offset: 10m,
}
