tracing-layer-win-eventlog
Layer for the tracing_subscriber to write to the Windows EventLog
Usage
If the Windows EventLog does not yet exist, it has to be created first.
# PowerShell v5.1 running as Administrator
New-EventLog -LogName Application -Source hello_world
use tracing_subscriber::{layer::SubscriberExt as _, util::SubscriberInitExt as _};
fn main() {
println!("Hello, world!");
let eventlog = tracing_layer_win_eventlog::EventLogLayer::new("hello_world".to_owned());
tracing_subscriber::registry()
.with(eventlog)
.init();
tracing::info!(id = 40, "hello world!");
}
The id
is optional and used as the Windows EventID and has to be unsigned
. If no id
is given, the tracing::Level
will be used as the EventID.
The parent spans are listed above the message in the source
key. If there are multiple parent spans they are concatenated with the /
separator.
All other objects that are passed are written below the message in a key: value
pair.
Example
#[tracing::instrument]
fn windows() {
let path = "C:\\Windows";
tracing::debug!(id=2,?path,"currently in windir");
}
The above example will be written to the EventLog as follows:
ID: 2
source: windows
message: currently in windir
path: "\"C:\\Windows\""
