8.3.1 UPS Load Alert
The SNMP/Web adapter monitors the UPS Output Percent Load and reports a UpsLoadAlert when the
load drops of a defined percentage (the actual load step detected is also saved in the UPS log).
This functionality warns the user that there has been a drop in the UPS load. This could indicate
potential issues with the UPS load (fuse blown, breaker tripped, unit off, etc.). Per current
implementation, the alert is only available for HTTP based monitoring.
The following commands (available over the command-line interface – local console or telnet) have
been introduced to control this functionality.
Command Parameters Description
load_alert_thres [-1 | 5..100]
This command controls the UPS Load Alert. The UPS output
percent load is monitored, and when the drops is above
the specified threshold is will report a UpsLoadAlert
condition.
The parameter is expressed in percentage of the UPS
rating: the threshold can be set to a value between 5%
and 100%.
Setting it to –1 disables the functionality.
Default value: 15%
This command controls the time that the SNMP/Web
adapter will maintain active the UpsLoadAlert notification.
Once the configured time is expired the notification is
reset.
The parameter is expressed in minutes: it can be set to a
value between 1 and 500 minutes.
[-1 | 1..500] load_alert_time
Setting it to –1 means that the notification will never be
reset.
Default value: 15 minutes
Note: when this value is set, the UpsLoadAlert is reset if
active.
This command controls a filtering and averaging
mechanism applied on the UPS output percent load
measurement. This mechanism aims to prevent reporting
false conditions following transient conditions.
[1..5] load_alert_filter The parameter can be set to a value between 1 and 5,
where 1 is no filtering/averaging and 5 is highest filtering.
Default value: 3
Note: it is not recommended to change this setting.
