4.4.5. Eyes

Domotz Eyes allow you to monitor services and other details on your network devices. Currently this includes:

 

  • TCP Services

 

  • SNMPv2 Sensors (via OID)

 

Other monitoring services may be added in the future.

4.4.5.1. Configuring a Domotz Eye

You will now see a new tab labelled Eyes. This is where you will configure the various TCP services or SNMP sensors. Please note that you can configure a maximum of 20 TCP services per device and unlimited SNMP sensors. The only limitation will depend on the plan you have subscribed to (see @5.2.2. Lite vs. Advanced vs. Premium‍).

4.4.5.2. How to add a TCP Service to be monitored

To Add a new TCP service to monitor, enter the name of the service or TCP port number associated with it and the search box will return all available services that match the text entered:

Once the TCP service is added, the Domotz Agent will start monitoring that service. The port will be marked as available (green) if the Service is available on that port or unavailable (red) if not:

On every single TCP service monitored, the user can set a “Custom” alert (from the Alerts tab) to be informed when the service change status (from available to unavailable and vice-versa):

4.4.5.3. How to configure an SNMP Sensor

4.4.5.3.1. Determine OID

It is very helpful to use an MIB Browser iReader like the following:http://ireasoning.com/mibbrowser.shtml – free version for end users). Using this tool it is possible to navigate the OID tree for devices that support SNMP to find the OID sensor that you want to monitor.

 

It is important to configure your MIB tool for SNMP version 2c

The following is an example of a Sensor that will allow you to monitor the level of black ink level of my printer. In order to do this you will need to find some information in order to find the data you are looking for:

 

Index number for Black cartridge
Maximum level for the black ink cartridge (to compare to current level in order to determine percentage consumed).
Current level of black ink cartridge
 

In order to do this, you will do the following:


1. You identify the reference index for the black cartridge (in this case the index is 4):

Using this index, I can get other details for OIDs that are related to this cartridge, i.e. the Maximum level and actual level of the toner in that cartridge which I can then monitor and use to define my alerts.

 

2. From the OID of the SuppliesMaxCapacity (in my case 1.3.6.1.2.1.43.11.1.1.8.1.4): you get 2500. This is the MAX value of the black toner that is supported by my printer. I will need this later to set up the alert.

 


3. Then you can get the the OID of the SuppliesLevel (the OID for the Black cartridge in the example is 1.3.6.1.2.1.43.11.1.1.9.1.4)

This OID is what you will add to Domotz and will begin to monitor from the Eye tab of the device (1.3.6.1.2.1.43.11.1.1.9.1.4)

You can refer to the manufacturer’s documentation to determine the correct OID and expected values
