Once in the service parameters, you will notice fields indicated with numbers of arguments representing the values of the thresholds. One field represents the value for the thresholds in “Warning” state and the other that of the “Critical” state. In our example, $ARG3$ and $ARG4$ represent these values but it should be noted that this can change from one service to another.
These fields are said to be dynamic, in other words, the values represented by these arguments can change from one type of service to another. Therefore, they are not specific for only entering values representing thresholds. We can see it in this example with $ARG2$ representing the name of the interface and $ARG1$ that of the SNMP community.
Still in our example, 90% is the default value that we defined for the “Warning” threshold in the $ARG3$ field and 97% for the “Critical:” threshold in the $ARG4$ field. You must therefore change these two values to the one you want in these fields then click on “Save” to save your modifications.
