- Reduce the example to one group; Fluent Bit uses only the last
  group in an upstream file.
- Use the tls.verify node key; tls_verify isn't recognized and is
  ignored.
- Replace the "defined globally" note: the section belongs in its
  own file, which the output's upstream parameter points to.
- Fix a grammar error and a hard line wrap.

• Documentation
  • Updated the upstream server configuration example and clarified required node settings.
  • Clarified that the section should be in a separate file referenced by the output plugin, and that only the last group is used when multiple groups are defined.

Walkthrough

The upstream server documentation now shows one forward-balancing group, uses tls.verify, and describes how to configure the group in a separate file and reference it with the output plugin’s upstream parameter.

Changes: Upstream server configuration

Layer / File(s)	Summary
Update upstream example and instructions administration/configuring-fluent-bit/yaml/upstream-servers-section.md	The example now uses tls.verify and contains one group. The documentation lists required node fields and says to place one group in a separate file referenced by the output plugin’s upstream parameter. It also states that Fluent Bit uses the last group if the file defines multiple groups.

Merge Risk: Low · previous review f2b34

The documentation fixes are correct, but the example now really disables TLS certificate verification for one node. Readers who copy it for remote servers could end up with an insecure setup, so consider changing it to true with a CA file before merging.

Full details: Title check

Explanation

The title names the documentation area and the two kinds of fixes made: the YAML upstream servers example and the file rules. The raw summary confirms the single edited file covers both: the example is reduced to one forward-balancing group, tls_verify becomes tls.verify, and the text now says the section belongs in a separate file. The title is specific and accurate, though the nested path prefix is somewhat long.

- Line 23: Update the `node-3` example so `tls.verify` is enabled and configure
`tls.ca_file` to reference a trusted CA certificate, rather than disabling
certificate verification.
