This SAM component monitor uses the SNMP protocol to retrieve an entry in a Management Information Base (MIB) by its Object Identifier (OID), and returns the value of the entry as a statistic. You can also use the Orion agent for Linux to monitor SNMP.
Value of the entry retrieved from the MIB.
Prerequisites for Orion agent for Linux
If using the Orion agent for Linux, you may need to complete additional configurations. See Configure Linux/Unix systems for monitoring by the Orion agent in SAM.
A default description of the monitor. You can override the default description by adding to or replacing the text, which is automatically saved. The variable to access this field is
Changing the default description to specify what will be monitored can be helpful when receiving alerts and notifications later.
Describes how the component monitor works.
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.
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.
Select this check box to open the Formula box where you can manipulate the returned value with a variety of mathematical possibilities. Choose common functions from drop-down lists to manipulate the returned value, or select the Custom Conversion option. See Convert values in data transformations for SAM component monitors for details.
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.
Add notes for easy reference. You can access this field by using the variable,
