Monitoring through network modules. TCP Service.Service

In this case, monitoring will be added to verify that an SMTP (mail)email) service is active on a machinemachine. will be added. Although this couldcan be a very complex check (simulating thatthe sending of user credentials and passwordspasswords, are sent, thatsending an email is sent,email, etc.), it will be simplified here by only checkingverifying that the port is open and responsive.responding.

To do that,this, repeat the samesome steps from the previous chapter,chapter butwill thisbe timerepeated: choosefirst creating an agent and then creating a "network module (Network module".TCP module):

ThenNext, use the drop-down controls until you find the desired check (is found, Check SMTP Server)(25), and click on it to create the module:module (only necessary fields are shown; ensure it brings the agent's IP address):

Finally, repeat the steps will be repeated (go to the operation view and refresh until the monitor appears). Until a module has no data, it will be BLUE, which indicatesindicating that it ishas not yet been initialized:

After a few secondsseconds, it should start and take a value,value: GREEN if the SMTP server responds, or RED if it does not:

Monitoring through server plugins.plugins. Network packet loss.loss

We are going to monitor the network packet loss using a remote check that comes pre-configuredpreconfigured in Pandora FMS. ForTo thatdo this, go to the configurationagent administration view, of any agent connected to your network, becauseas we are going towill measure the packet loss from Pandora FMS to the IP address of thatany agent.

The configuration view can be accessed through the cogwheel icon:

From there go to the module view:

And we will create a "Plugin"module module:of the Plugin type:

SoYou must enter the IP address of the device to be monitored in the Target IP field before saving the new module should look like this:module.

We chose a "library" module that uploads some values automatically.
