SNMP Monitor

This SAM component monitor uses the SNMP protocol to retrieve an entry in a MIB by its OID, and returns the value of the entry as a statistic.

Statistic

Value of the entry retrieved from the MIB.

Prerequisites for Orion Platform agent for Linux

If using the Orion Platform agent for Linux, additional setup may be required. See Configure Linux/Unix systems for monitoring by the Orion Platform agent in SAM.

Field descriptions

Description

A default description of the monitor. To override the default description, add to or replace existing text. Changes are automatically saved. The variable to access this field is ${UserDescription}.

Customize descriptions to specify what will be monitored so related alerts and notifications are more meaningful later.

Component Type

Describes how the component monitor works.

Enable Component

Determines if the component is enabled. Disabling the component leaves it in the application in a deactivated state not influencing either SolarWinds SAM application availability or status.

Method Type

Get: A manager-to-agent request to retrieve the value of a variable or list of variables. Desired variables are specified in variable bindings (values are not used). Retrieval of the specified variable values is to be done as an atomic operation by the agent. A response with current values is returned.

Get Next: A manager-to-agent request to discover available variables and their values. Returns a Response with variable binding for the lexicographically next variable in the MIB. The entire MIB of an agent can be walked by iterative application of GetNextRequest starting at OID 0. Rows of a table can be read by specifying column OIDs in the variable bindings of the request.

Object Identifier (OID)

Specify the OID of the entry in the MIB you want to retrieve.

Custom SNMP port

The port number of the custom SNMP port. Set this field to 0 to use the default SNMP port defined in the Node’s properties.

Count Statistic as Difference

Changes the statistic to be the difference in query values between polling cycles.

Convert Value

Select the "Yes, convert returned value" option to display fields where you can select a common function or enter a custom formula. The Custom Conversion option provides basic arithmetic operators (+, -, *, /), plus built-in mathematical functions for more advanced conversions. See Convert values in data transformations for SAM component monitors.

Statistic Threshold

Specify when a threshold that indicates a warning or critical level has been breached. Logical operators are in the drop down followed by a blank field for you to enter the value of this threshold. For example: Less than 15 for warning, and Less than 5 for critical. See Application Monitor Thresholds.

User Notes

Add notes for easy reference. You can access this field by using the variable, ${UserNotes}.
