Threshold Notification Overview • Min - When collected data drops below a value, report an error • Equal - When collected data equals a value, report an error • What message should be generated when the threshold is exceeded. • At what value should this threshold get reset. Thresholds are defined and associated with statistics. A single statistic can have many thresholds indicating a severity such as Critical, Major, Minor, etc. Whenever data is collected for the statistic, it is cross-checked with the associated thresholds. If the collected value exceeds the thresholds, then the threshold message is displayed. Refer to the following figure. FIGURE 8-5 Threshold Processing Thresholds can be created, modified, or deleted directly in the AlliedView NMS internal file by defining the attributes of the thresholds. Warning: Editing configuration files directly should only be done under the supervision of Allied Telesis support personnel, since it is very easy to delete or change thresholds that would result in a loss of threshold monitoring for devices. Moreover, any changes in one file need to be coordinated with changes in other files. Use the forms and menus described in this section to set up thresholds. There are three threshold types: • Long Values Thresholds can be associated with Data identifiers for which data collected is of type long. Some of such sample Data identifiers are IfAdminStat, IfOperStat etc. in RFC 1213 MIB. The value you provide for this Threshold will be compared as it is with data collected for the identifier. • String Values Thresholds can be associated with Data identifiers for which data collected is of type string. An example is SysDescr. To monitor a change in system description use String Thresholds. • Percentage Values 8-12 AlliedView NMS Administration Guide (Setting Up Performance Management)
