These IDs are independent of the IDs that you see in the first column of the list. PRTG translates them into the corresponding strings. The numbers are the IDs of the SLA types as reported by the target device. The sensor can support the following operations with the specified type IDs: If a type is missing, check the configuration of the target device. The list options depend on the configuration of the target device that you query. PRTG creates one sensor for each SLA that you select. Select the IP SLAs that you want to monitor. The settings that you select in the Add Sensor dialog are valid for all sensors that you create when you finish the dialog. You can change nearly all settings on the sensor's Settings tab after creation. Therefore, you do not see all settings in this dialog. It only shows the settings that are required to create the sensor. The Add Sensor dialog appears when you manually add a new sensor to a device.

You can change the behavior of a channel by editing the lookup file that the channel uses. This means that possible states are defined in a lookup file. This sensor uses lookups to determine the status values of one or more channels.This sensor has a low performance impact.If there is a very large number of IP SLAs available during sensor creation, we recommend that you limit the result set by using the Start Interface Index and End Interface Index options in the SNMP Compatibility Options setting of the parent device or group.If you encounter this issue, open the SNMP Compatibility Options setting of the parent device or group and set the Request Mode to Use single get. The sensor shows the following error message: No such object (SNMP error # 222). In certain cases, the object identifiers (OID) that the sensor uses are not available on the target device.
