####OPEN SOURCE & CROSS-PLATFORM TOOL FOR SIMPLIFIED MONITORING ####getwarden.net
Define "health checks" for your applications, resources and infrastructure. Keep your Warden on the watch.
Warden is a simple, cross-platform library, built to solve the problem of monitoring the resources such as the websites, API, databases, CPU etc.
It allows to quickly define the watchers responsible for performing checks on specific resources and integrations to easily notify about any issues related to the possible downtime of your system.
Each watcher might have its own custom interval. For example you may want to check e.g. the API availability every 500 milliseconds, while the database should respond only every 10 seconds and so on. Or you could just set the common one interval (5 seconds by default) for all of the watchers.
On top of that, you may use all of this information to collect the custom metrics thanks to the hooks.
- Disk
- MongoDB
- MSSQL
- Performance
- Process
- Redis
- Server
- Web
- SSL certificates (3rd party)
- Azure Storage (3rd party)
- Azure Service Bus (3rd party)
You can make use of the Web Panel which provides the UI for organizing your monitoring workspace, dashboard with real-time statistics and the storage of the historical data. If you don't want to host it on your own, there's an online version available, running in the Azure cloud at panel.getwarden.net
Yes, please navigate to the wiki page where you can find detailed information about configuring and running the Warden.
Available as a NuGet package.
Install-Package Warden
Watchers and integrations are available as a separate NuGet packages listed here.

Configure the Warden by adding the watchers and setting up the hooks and integrations to get notified about failures, successful checks, exceptions etc. - use that information e.g. in order to let your system administrator know when something goes wrong or to build your custom metrics.
var configuration = WardenConfiguration
.Create()
.AddWebWatcher("http://my-website.com")
.AddMongoDbWatcher("mongodb://localhost:27017", "MyDatabase", cfg =>
{
cfg.WithQuery("Users", "{\"name\": \"admin\"}")
.EnsureThat(users => users.Any(user => user.role == "admin"));
})
.IntegrateWithSendGrid("api-key", "noreply@system.com", cfg =>
{
cfg.WithDefaultSubject("Monitoring status")
.WithDefaultReceivers("admin@system.com");
})
.SetGlobalWatcherHooks(hooks =>
{
hooks.OnStart(check => GlobalHookOnStart(check))
.OnCompleted(result => GlobalHookOnCompleted(result));
})
.SetAggregatedWatcherHooks((hooks, integrations) =>
{
hooks.OnFirstFailureAsync(results =>
integrations.SendGrid().SendEmailAsync("Monitoring errors have occured."))
.OnFirstSuccessAsync(results =>
integrations.SendGrid().SendEmailAsync("Everything is up and running again!"));
})
.SetHooks(hooks =>
{
hooks.OnIterationCompleted(iteration => OnIterationCompleted(iteration))
.OnError(exception => Logger.Error(exception));
})
.Build();
Start the Warden and let him do his job - now you have the full control over your system monitoring!
var warden = WardenInstance.Create(configuration);
await warden.StartAsync();
