# Monitors Troubleshooting

## Monitor Not Generating Alerts

**Possible causes:**

* Monitor is disabled (check toggle)
* Thresholds are too lenient
* Data isn't violating conditions
* Asset isn't receiving new data

**Solutions:**

1. Verify monitor is enabled
2. Review threshold configuration
3. Check asset data freshness
4. Test with known violation scenario

## Too Many False Positives

**Possible causes:**

* Thresholds too strict
* Not accounting for normal variance
* Using Absolute when Automatic would be better

**Solutions:**

1. Switch to Automatic thresholds
2. Widen Acceptable Range
3. Increase Acceptable Drift %
4. Review historical data patterns

## Monitor Configuration Errors

**Common issues:**

* Invalid expression syntax
* SQL query errors
* Unsupported aggregations
* Attribute not found

**Solutions:**

1. Verify syntax follows documentation
2. Test SQL queries in your data warehouse first
3. Confirm attributes exist in asset
4. Check for typos in attribute names

## Cannot Edit Monitor Type

**Issue:** Monitor type cannot be changed after creation

**Solution:**

1. Create a new monitor with desired type
2. Copy configuration settings
3. Disable or delete old monitor
4. Enable new monitor

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.telm.ai/telmai/monitoring-data/monitors-management/monitors-troubleshooting.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
