# Tune Monitoring for Latency, Accuracy, and Cost

> Tune live-monitor and live-digest settings for reliability and efficiency

## Goal

Balance detection speed, output quality, and usage cost for your workload.

## Shared Tuning Principle

Start from a reliable condition, then adjust only one parameter at a time.

1. Validate stream with [Validate Stream](/api-reference/streams-validate)
2. Validate condition with [Check Once](/api-reference/check-once)
3. Launch monitor or digest
4. Review runtime output via [Get Job Details](/api-reference/jobs-get)
5. Iterate

## Live Monitor Levers

### `interval_seconds`

How often condition checks run.

* lower values: faster detection, higher usage
* higher values: slower detection, lower usage

### Condition quality

Precise conditions reduce false triggers and wasted reruns.

Guide: [Writing Reliable Conditions](/guides/writing-conditions)

## Live Digest Levers

### `window_minutes`

How much time each summary covers.

* shorter windows: more frequent summaries
* longer windows: fewer summaries

### `capture_interval_seconds`

How often frames are sampled.

* lower intervals: richer detail, higher usage
* higher intervals: lower usage, less detail

### `max_windows`

Optional cap on number of summary windows per job.

## Starting Profiles

### Fast incident detection (`live-monitor`)

```json theme={null}
{
  "interval_seconds": 10
}
```

### Balanced digest (`live-digest`)

```json theme={null}
{
  "window_minutes": 10,
  "capture_interval_seconds": 60
}
```

### Cost-controlled digest (`live-digest`)

```json theme={null}
{
  "window_minutes": 30,
  "capture_interval_seconds": 180
}
```

## Common Mistakes

* Skipping `check-once` before long runs
* Changing multiple parameters at once
* Using vague conditions that inflate noise
