the job will repeat. The Weeks and Months tabs also allow you to set collection to occur on
certain days or during certain months. Once you’ve set the interval, click the Add button
and the new collection interval will appear beneath the box.

˽ Attach to Multi-drop Server (if available) – Causes Collector to assign this sensor,
along with any other sensor that has the same IP/port and has this setting checked, to
a multi-drop collection group. For multi-drop–capable sensors on a common IP/port,
Collector supports optimized multi-drop communication for a set of sensors with a
common communication gateway.
The following is a list of important notes about multi-drop collection:
˽ Sensors assigned to the same multi-drop server for collection MUST have the same
collection interval, even if the individual sensor intervals are different.
If a multi-drop server group using this IP/port already exists when a sensor is added, its
collection interval will automatically be changed to the group value. If no other sensors
are currently set to be collected via multi-drop, this sensor will become the start of a
new group, and will use the sensor’s current collection interval as the group collection
interval; future sensors added to the group will have their collection intervals changed
to this value.
˽ A sensor does NOT need to have multi-drop collection enabled even if it shares an IP/
port with other sensors. Multi-drop collection must be disabled if a different collec-
tion interval is required for a sensor. Each sensor that is NOT enabled for multi-drop
communication with the same IP/port combination as other sensors will be competing
with those sensors for a common connection. If one Collector collection thread is us-
ing a connection, other competing threads will have to wait until the communication
pathway is open before continuing.
˽ Proper multi-drop data collection requires the use of a driver that specifically supports
multi-drop capable sensors. If the current sensor driver is incapable of supporting
multi-drop communication, enabling multi-drop data collection for this sensor will
result in data collection errors.
