Introduction
WatchMyDC supports adding a custom metric (SNMP OID) for a physical node. This document demonstrates the process of adding an SNMP OID from a MIB for observability and alert creation.
Dependency and Limitations
- The WatchMyDC MIB repository contains MIBs' from most manufacturers. However, in case a MIB is not present in the list please contact WatchMyDC support with the vendor & MIB name. (WatchMyDC will be allowing customers to import their own custom MIBs' soon.)
- 'Line Chart' and 'Text/Num' card supports a single OID.
- It takes 4-5 minutes to display the value or graph after adding the custom metric.
- WatchMyDC does not support custom metrics on WMI nodes as of now.
