The VMware vRealize Operations Management Pack for SNMP guide provides information about installing and configuring the Management Pack for SNMP.
Introduction to SNMP
The Simple Network Management Protocol (SNMP) is a standard Internet protocol for managing devices on IP networks. The SNMP adapter is an embedded adapter for vRealize Operations Manager that collects metrics from devices that support SNMP. These devices typically include routers, switches, servers, workstations, and printers.
SNMP displays management data on SNMP managed devices as variables, which are organized in hierarchies. Management Information Base (MIB) files describe these hierarchies and contain object identifiers (OIDs) that identify each variable.
The SNMP adapter uses MIB files to identify the metrics that have to be collected from a particular device. When you install the SNMP adapter, the installation utility places a set of standard MIB files in the conf/mib folder. You can import additional MIB files after you install the SNMP adapter. The MIB files that are added will appear in the MIB list drop-down menu.
The SNMP adapter supports devices that are configured with SNMP v2C and V3. The SNMP adapter supports auto-discovery of devices when you add a range or pool of IP addresses while configuring the adapter. The SNMP adapter does not support the device with V3 Auth Only, the v3 device must have both Authentication and Privacy Protocols enabled.
The SNMP adapter ships a range of MIB files, and metrics are created for all the OIDs that have the data type that the Management Pack supports. By default, all metrics are created but none are enabled. You can enable metrics by using Policies to monitor network devices and its components.
The information in this guide is intended for anyone who wants to install and configure the Management Pack for SNMP.
