Expand description

Tracing configuration section.

Fields

use_color: bool

Whether to use colored terminal output, if available.

Colored terminal output is automatically disabled if an output stream is connected to a file. (Or another non-terminal device.)

Defaults to true, which automatically enables colored output to terminals.

filter: Option<String>

The filter used for tracing events.

The filter is used to create a tracing-subscriber EnvFilter, and more details on the syntax can be found there or in the examples below.

If no filter is specified (None), the filter is set to info if the -v flag is given and warn if it is not given.

Examples

warn,zebrad=info,zebra_network=debug sets a global warn level, an info level for the zebrad crate, and a debug level for the zebra_network crate.

[block_verify{height=Some\(block::Height\(.*000\)\)}]=trace

sets trace level for all events occurring in the context of a block_verify span whose height field ends in 000, i.e., traces the verification of every 1000th block.

endpoint_addr: Option<SocketAddr>

The address used for an ad-hoc RPC endpoint allowing dynamic control of the tracing filter.

If this is set to None, the endpoint is disabled.

flamegraph: Option<PathBuf>

Controls whether to write a flamegraph of tracing spans.

If this is set to None, flamegraphs are disabled. Otherwise, it specifies an output file path, as described below.

This path is not used verbatim when writing out the flamegraph. This is because the flamegraph is written out as two parts. First the flamegraph is constantly persisted to the disk in a “folded” representation that records collapsed stack traces of the tracing spans that are active. Then, when the application is finished running the destructor will flush the flamegraph output to the folded file and then read that file and generate the final flamegraph from it as an SVG.

The need to create two files means that we will slightly manipulate the path given to us to create the two representations.

Example

Given flamegraph = "flamegraph" we will generate a flamegraph.svg and a flamegraph.folded file in the current directory.

If you provide a path with an extension the extension will be ignored and replaced with .folded and .svg for the respective files.

use_journald: bool

The use_journald flag sends tracing events to systemd-journald, on Linux distributions that use systemd.
