The Outages tabs displays the states of the services (probes) and the History tab shows the response times of the probes on this server. You should check out the other tabs of the devices setting. Under Services, I added the MySQL probe I created and also the preset http and ping probes. I, then, opened the settings of my test server in the Devices folder. It is possible to create multiple email notification methods. You can configure such general settings by clicking on the corresponding symbol in the toolbar of The Dude. It probably makes more sense to use just one SMTP server for all outgoing email notifications. You just have to specify the address and the SMTP server. Creating an email notification is simple. There are already a couple of preconfigured notifications such as "popup", "beep" or "log to eventlog". Next, I created an email notification method in the Notification folder. You could also send a command to the server and let The Dude wait for a certain response (see screenshot). I configured the probe to connect to the TCP port 3306 only.
THE DUDE PLUS
You just have to click on the red plus symbol on the toolbar to add a new probe. In my test, I created a probe to monitor a MySQL server. You can also create your own probes easily.

But the The Dude also lets you monitor routers, switches, disk space, memory and so on. You will find the most famous network services like HTTP, Netbios or SMTP here. The Probes folder shows the services you can monitor out of the box. The fact that there are 15 more folders lets you guess that The Dude has countless features to offer.

To set up monitoring for a server, you only need the Probes, the Devices, and the Notification folder. Scanning networks can take a while and the many devices displayed will only confuse you. If you have a big network, it is probably better to run your tests in a small subnet first. After the installation, you have to specify the subnets you want to monitor.
