I’m having trouble with the content\_encoding = “gzip” setting in the telegraf config. It does not appear to work for me. I’m seeing 0 bytes at the target http output webserver.

- Default encoding works. (uncompressed)
- GZIP encoding sent manually via curl command works as well. (see below)

I’m using same input for comprressed and decompressed cases from telegraf.

Is there anything I’m missing from my telegraf config file below? My sample python webserver use the following code to decompress and print the output.

```
            with gzip.GzipFile(fileobj=BytesIO(raw_data)) as gz:
                decompressed_data = gz.read().decode('utf-8')
            print("Decompressed Data:\n", decompressed_data)

```

**Debug Webserver Output - Uncompressed output works fine.**

**Disregard this issue.**

This was a problem with my test webserver which was looking at content-length. Telegraf will send GZIP’d data as chunked, so content-length will always be 0. If content-length is 0, I needed to check if payload data is chunked and read payload accordingly. In any case, this is not a telegraf issue.
