Setting Data Logging - LEGRAND Server Technology PRO3X User Manual

Device > Any sub-event
▶
Example 3
This example illustrates a situation where two event rules combined regarding the outlet state changes
causes the PRO3X to continuously power cycle outlets 1 and 2 in turn.
Event selected
Outlet > Outlet 1 > Sensor > Outlet State > On/Off >
Both (trigger condition)
Outlet > Outlet 2 > Sensor > Outlet State > On/Off >
Both (trigger condition)
A Note about Untriggered Rules
In some cases, a measurement exceeds a threshold causing an alert. The measurement then returns to
a value within the threshold, but the PRO3X does not generate an alert message for the Deassertion
event. Such scenarios can occur due to the hysteresis tracking the PRO3X uses. See "To De-assert" and
Deassertion Hysteresis.

Setting Data Logging

The data log stores records of each internal sensor's readings. You can configure the log capacity and
the frequency that measurements are taken and stored. The total size of the data log is limited due to
memory constraints. For example, for a PDU with 500 sensors, the effective log size cannot be more
than 200 records. A log capacity warning appears if the desired log capacity is higher than the effective
log capacity.
You can configure how often measurements are written into the data log using the Measurements Per
Log Entry field. Since the internal sensors are measured every second, specifying a value of 60, for
example, would cause measurements to be written to the data log once every minute. Whenever
measurements are written to the log, three values for each sensor are written: the average, minimum
and maximum values. For example, if measurements are written every minute, the average of all
measurements that occurred during the preceding 60 seconds along with the minimum and maximum
measurement values are written to the log.
The device's SNMP agent must be enabled. In addition, using an NTP time server ensures accurately
time-stamped measurements.
By default, data logging is enabled. You must have the "Administrator Privileges" or "Change Pdu, Inlet,
Outlet & Overcurrent Protector Configuration" permissions to change the setting.
Important: The third-party management solutions like PowerIQ rely on the data logging feature, and the
settings should be changed only in accordance with those systems' requirements.
