case of a Script, HTTP, TCP, or gRPC check. Can be specified in the form of "10s"
or "5m" (i.e., 10 seconds or 5 minutes, respectively).
- `OutputMaxSize` `(positive int: 4096)` - Allow to put a maximum size of text

is 4k.
The value can be further limited for all checks of a given agent using the
`check_output_max_size` flag in the agent.
- `TLSSkipVerify` `(bool: false)` - Specifies if the certificate for an HTTPS
check should not be verified.

Many options allow configuring a subsection of either the bootstrap or

Overrides](#escape-hatch-overrides). Both require writing Envoy config in the
protobuf JSON encoding. Advanced options cover smaller chunks that might
commonly need to be set for tasks like configuring tracing. In contrast, escape hatches
give almost complete control over the proxy setup, but require operators to
manually code the entire configuration in protobuf JSON.
