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