No-op

No-op stands for "No operation". No-op scaler is used for debugging purposes. It doesn't do anything other than logging the event data received from the triggers connected to it.

Configuration

[[scaler]]
type = "noop"
id = "<choose a name>"

Example

The following waymond config would periodically trigger the buildkite trigger. The events from buildkite trigger will not be used to perform any autoscaling operation. Instead, the noop scaler connected to it will log all the event data in waymond logs.

[[trigger]]
type = "cron"
id = "global_cron"
expression = "*/1 * * * *"

[[trigger]]
type = "buildkite"
id = "my_buildkite_org"
# set BUILDKITE_TOKEN environment variable

[[connect]]
type = "direct"
id = "check_my_buildkite_org_queues_periodically"
from = "trigger.global_cron"
to = "trigger.my_buildkite_org"

[[scaler]]
type = "noop"
id = "noop"

[[connect]]
type = "direct"
id = "print_trigger_output"
from = "trigger.my_buildkite_org"
to = "scaler.noop"

Events

Emits scaler.<id>.output event that produces the same data received in the noop scaler as the input via scaler.<id>.input event.
