There's no direct limit of SNMP Trap elements in the system. But there's a limit for overall elements in the system. Please use the table from "Comparison chart: Master modules", "Comparison chart: PDUs", horizontal field "Max. amount of elements:". |
Introduction
All Vutlan monitoring systems support SNMP GET element,.
Virtual sensor "SNMP Get" is used to read data from external equipment via SNMP PDU GET (v1, v2c, v3). The "SNMP Get" sensor can be analog or discrete type. The analog sensor interprets the value read by SNMP as a decimal number, extraneous characters (if they are in the data line) are discarded. The discrete sensor compares the read value with the given sample (called "Normal value"), and if the sample is contained in the data line, then the element takes the state "normal", if the sample is not in the line, it takes the state "alarm".

# | Name | Description |
|---|---|---|
1 | Name | Created element name |
2 | User-defined type | Defines the icon to be displayed in the "System tree" |
3 | Units of measurement | The unit of measure in which the value is displayed in the "System tree" |
4 | Minimum value | Determines the minimum measurement range, when the value is out of range, the sensor goes into the "Not connected" state |
5 | Maximum value | Determines the maximum measurement range, when the value is out of range, the sensor goes into a "Not connected" state |
6 | Alarm and warning levels | Defines the alarm and warning thresholds, as for other sensors, see Sensor configuration |
7 | Hysteresis | Option of setting the hysteresis state, see Sensor configuration |
8 | Expression | Function of the form f (x). The default value for the sensor is equal to the measured value: "x", ie corresponds to the expression "x". To calculate the indirect value of the sensor is possible to use an arbitrary expression, which are permissible "(", ")", as well as:
For example: "0.1*x+0.5" |
