Tracker follows Cloudwatch's evaluation approach:
When you create a task, you specify three settings to enable tracker to evaluate when to change the task state:
- Name is a symbolic string that describes the task
- Datapoints is the number of data points that will conform the evaluation period for the task. The data points will be consecutive and treated as 1 per day.
- Tolerance is the number of days without acks or
backupsfrom a given task that before triggering an error state.
| System got | Datapoints | Tolerance | Status | Why? |
|---|---|---|---|---|
| X X X X X | 5 | 0 | OK | Over the last 5 days, the task tracked 5 backups (x),5 (5 backups) >= 5 (5 datapoints - 0 tolerance) |
| _ X X X _ | 5 | 2 | OK | 3 backups >= 5 datapoints - 2 tolerance |
| X X X | 5 | 0 | INSUFFICIENT | Task needs 5 datapoints to determine status. We'll have to wait 2 more days |
| X X X _ _ | 5 | 1 | ERROR | This assertion failed: 3 backups >= 5 datapoints - 1 tolerance |
The tracker package exposes a customizable tracker client that wraps the rest API. or manipulate Go programs.
t := tracker.New(apiKey)
err := t.CreateBackup(taskID)
Exposes a simple CLI to track backups. Refer to releases.
API_KEY is required to be defined as env var.
