# ElasticsearchException: Rollup job [my_rollup] cannot be started because the index pattern [logs-*] does not match any existing indices with matching rollup configuration

- **ID:** `elasticsearch/rollup-job-configuration-mismatch`
- **Domain:** elasticsearch
- **Category:** config_error
- **Verification:** ai_generated
- **Fix Rate:** 78%

## Root Cause

The rollup job's index pattern does not match any indices that have the required rollup configuration, or the indices were created after the rollup job was defined without proper metadata.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 7.13.0 | active | — | — |
| 8.6.0 | active | — | — |
| 8.12.0 | active | — | — |

## Workarounds

1. **Delete the rollup job and recreate it after ensuring the index pattern matches existing indices: DELETE /_rollup/job/my_rollup, then PUT /_rollup/job/my_rollup with the correct index pattern and matching field definitions.** (85% success)
   ```

   ```
2. **Use the Rollup Index Capabilities API to check which indices have rollup metadata: GET /logs-*/_rollup/data, then manually add the rollup metadata to missing indices using the Update Index Settings API: PUT /logs-2025/_settings { 'index.rollup.meta': { 'job': 'my_rollup' } }.** (75% success)

   ```

## Dead Ends

- **** — Manually creating indices with the same name pattern does not automatically set the rollup metadata; the indices must be created through the rollup job or have the _rollup.meta field set. (75% fail)
- **** — Restarting the rollup job with the same configuration will fail again because the underlying indices are still mismatched. (90% fail)
