Crate nagiosplugin[−][src]

The nagiosplugin crate provides some basic utilities to make it easier to write nagios checks.

Macros

Let’s you simply create a resource from multiple metrics. It’s a bit like the vec! macro.

PartialOrdMetric	A PartialOrdMetric is a metric which will automatically calculate the State based on the given value and warning and/or critical value.
Resource	A Resource basically represents a single service if you view it from the perspective of nagios. If you init it without a state it will determine one from the given metrics.
SimpleMetric	Represents a simple metric where no logic is performed. You give some values in and the same get out.
StaticCheckable	Use a `StaticCheckable` for things you want to check but which do not contain a metric.

State	Represents a service state from nagios.
Unit

Checkable	The checkable trait represents anything that has some relevance as a checkable entity in icinga. Most notably `Metric`s. There are also `StaticCheckable`s which do not contain any metrics but influence the service state and output of the plugin.
Metric	This trait can be implemented for any kind of metric and will be used to generate the final string output for nagios. Calls to the functions should return immediately and not query the service every time.
ResourceMetric	Represents a single metric of a resource. You shouldn’t need to implement this by yourself since the crate provided types already implement this.
ToPerfString	The purpose of ToPerfString is only so one can define custom representations of custom types without using the ToString trait so we don’t interfere with that.

safe_run	Runs the given closure and exits with a State::Critical after printing out the error message if the Result contains an Err.
safe_run_sync	Runs the given closure and exits with a State::Critical after printing out the error message if the Result contains an Err.
safe_run_with_state	Runs the given closure and exits with the given State after printing out the error message if the Result contains an Err.
safe_run_with_state_sync	Runs the given closure and exits with the given State after printing out the error message if the Result contains an Err.
