![]() Each OID is a managed object containing a specific value. What is a MIB?Ī MIB is a hierarchical collection where each entry is addressed through an object identifier called OID. The Printer-MIB Management Information Base (MIB) is essential for this process. For instance, we want to receive an email when the black ink falls below a 10% capacity. In order to monitor the ink levels on a printer you’ll need to set up different SNMP sensors, one for each of the colors of our printer and add an alert when one of these values falls below a specific threshold. Introduction to automating SNMP monitoring with Node-RED Thanks to a Node-RED flow, we will be able to setups the SNMP triggers for new printers without user intervention.Īs the example in this tutorial, I chose an example of monitoring printer ink levels, however, the very same approach can be easily applied and used in many different scenarios including: In this Node-RED SNMP tutorial, we’ll cover how to monitor the ink levels of printers and be alerted when the ink levels fall below a defined threshold. SNMP is a powerful tool that can help you better monitor and get alerts for essential networked devices from printers to storage arrays. ![]()
