• Value
• Type
• Max - When collected data exceeds a value, report an error
• 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
