6.4.1 Types

The threshold types can be edited at the Settings=>Thresholds=>Types menu. Each threshold may belong to a type which does not need to be specified, therefore when a type is deleted, the thresholds belonging to that type will not be deleted but become typeless. The types have these parameters:

·       Name

·       Deduplication window: if an alarm is cleared and raised again within this window then PVSR reopens the alarm instead of creating a new one. If a threshold or an even is not having a type like the one configured on this page or the type does not have any setting for this then the application will use the THRESHOLD_DEDUP_WINDOW and the EVENT_DEDUP_WINDOW parameters in the CONFIG_INI.pm file.

·       Optional up and down SNMP trap: with the help of the SNMP Up Trap parameter the trap to be used in case of a threshold violation can be set, and the SNMP Down Trap parameter specifies the trap to be used when the violation ends

·       Alarm and Clear e-mail: use the custom e-mail notifications when an alarm is raised or cleared instead of the default e-mail notifications

The types have two purposes: they can be used when filtering the alarms, on the other hand they can be used to send out a custom SNMP traps or custom e-mails when a threshold violation occurs or ends. If a threshold has an SNMP trap value set then

·       If it has a threshold type and the type has a corresponding (up or down) trap and at least one variable in the trap can be filled in according to the specification of the trap then the system sends that custom trap

·       If any of the condition above do not apply then it sends the standard PVSR trap

If a threshold has an e-mail set then

·       If it has a threshold type and the type has a corresponding custom e-mail and at least one variable in the e-mail can be filled in according to the specification of the e-mail and the e-mail address is configured to receive one e-mail per alarm notification then the system sends that custom e-mail

·       If any of the condition above do not apply then it sends the standard PVSR e-mail

A restricted administrator cannot edit a type if it is used by a threshold template or by a threshold for which the user doesn’t have right.

One of the threshold type can be specified as default in the CONFIG_INI.pm file with the DEF_THRESHOLD_TYPE parameter. The value of the parameter must be the ID of the threshold type.
