Function nagiosplugin::safe_run

pub fn safe_run<E>(
    f: impl FnOnce() -> Result<Resource, E>,
    error_state: ServiceState
) -> RunResult<E>

Helper function to safely run a check with a defined ServiceState on error and return a RunResult which can be used to print and exit.

Example

use std::error::Error;

use nagiosplugin::{safe_run, Metric, Resource, ServiceState, TriggerIfValue};

fn main() {
    safe_run(do_check, ServiceState::Critical).print_and_exit()
}

fn do_check() -> Result<Resource, Box<dyn Error>> {
   // The first metric will not issue an alarm, the second one will.
   let resource = Resource::new("foo")
        .with_description("This is a simple test plugin")
        .with_result(Metric::new("test", 15).with_thresholds(20, 50, TriggerIfValue::Greater))
        .with_result(Metric::new("alerting", 42).with_thresholds(40, 50, TriggerIfValue::Greater));

    Ok(resource)
}
