Simple Network Management Protocol (SNMP) is an "Internet-standard protocol for managing devices on IP networks". Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks, and more. It is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. SNMP is a component of the Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF). It consists of a set of standards for network management, including an application layer protocol, a database schema, and a set of data objects. SNMP Agents expose ‘MIB Objects’ expressed as Variables.
SNMP Server module allows SNMP agent exploring, crawling for exposed variables, displaying real-time values on the mobile clients and monitoring variables for changes using configured rules.
Using VSAX Manager you start by discovering your network for SNMP agents by clicking on the button 'Manage SNMP Agents' and then on 'Discover'
or you can manually add them by providing the connection details.
After the SNMP agent configuration is complete you need to add the variables you wish to monitor. You can add variables from the Edit Agent dialog inside the Variables tab.
In order to correctly identify each of the variable's type and usage you need to consult the “SNMP MIB Reference Guide” released by the vendor of the agent. The MIB Document contains information regarding each variable exposed by the SNMP agent.
It is possible to manually write the variable Oid (Object identifier) or using the crawl (“...” button in the Add Variable dialog) feature.
Inside the Notifications tab in VSAX Manager, Server Modules sub tab in SNMP sub tab you can configure notifications for monitored SNMP variables.
How to enable notifications for SNMP monitoring
“SNMP” tab contains a list of notification rules for monitored SNMP Variables. To configure SNMP notifications you must first add a SNMP agent and the variables that you are interested in. Consult the MIB Document released by the device’s or software’s vendor to get an accurate information of each variable’s purpose.
To add a SNMP click on “Add” button, select a variable from the monitored variables list by pressing the “…” button and double clicking (or selecting a variable and pressing “OK”), input variable’s type and choose a notification condition.
Note: You may have more than one notification rule for one SNMP variable.
