Troubleshoot issues writing data
Learn how to avoid unexpected results and recover from errors when writing to InfluxDB.
If InfluxDB OSS successfully writes all the request data to the bucket, InfluxDB returns success (HTTP
204 status code).
The first rejected point in a batch causes InfluxDB to reject the entire batch and respond with an HTTP error status.
Review HTTP status codes
InfluxDB uses conventional HTTP status codes to indicate the success or failure of a request. Write requests return the following status codes:
204Success: All request data was written to the bucket.
400Bad request: The line protocol data in the request was malformed. The response body contains the first malformed line in the data. All request data was rejected and not written.
401Unauthorized: May indicate one of the following:
404Not found: A requested resource (e.g. an organization or bucket) was not found. The response body contains the requested resource type, e.g. “organization”, and resource name.
413Request entity too large: All request data was rejected and not written. InfluxDB OSS only returns this error if the Go (golang)
ioutil.ReadAll()function raises an error.
500Internal server error: Default HTTP status for an error.
503Service unavailable: Server is temporarily unavailable to accept writes. The
Retry-Afterheader describes when to try the write again.
message property of the response body may contain additional details about the error.
If some of your data did not write to the bucket, see how to troubleshoot rejected points.
If you notice data is missing in your bucket, do the following:
- Check the
messageproperty in the response body for details about the error.
- If the
messagedescribes a field error, troubleshoot rejected points.
- Verify all lines contain valid syntax (line protocol or CSV).
- Verify the timestamps match the precision parameter.
- Minimize payload size and network errors by optimizing writes.
Troubleshoot rejected points
InfluxDB rejects points for the following reasons:
- The batch contains another point with the same series, but one of the fields has a different value type.
- The bucket contains another point with the same series, but one of the fields has a different value type.
