Data Aggregator Configuration Changes During Network Disconnects to a Data Collector Host

Occasionally, the connection between a Data Aggregator host and a Data Collector host breaks, such as, when a network disconnect occurs. If the Data Aggregator and Data Collector processes are running during a disconnect, you can make configuration changes to the Data Aggregator installation. In this case, polling continues on the Data Collector host according to the configuration that existed before the network disconnect. Once the connection between the Data Aggregator and the Data Collector hosts reestablishes, Data Collector downloads the new configuration and adjusts polling accordingly.

For example, you make one of the following configuration changes:

• Change the expression an SNMP vendor certification uses to calculate a value on a metric family.
• Change the metric family to poll a new operational metric.

When the connection between the Data Aggregator and the Data Collector hosts is broken, the changes cannot take effect. After reconnection, Data Collector begins polling the new SNMP MIB objects used in the new expression or in calculating the new operational metric.
