My entire devices performance data collection not happening within poll time interval? Is there any configuration like increasing threads or any other option so that it attempts to collect more number of nodes in bulk?

Yes, there is back end DB configuration available which can be used to fine tune the number of threads so that we can poll more number of nodes at a time in parallel. These threads can be fine tuned per data collector level that is, SNMP, WMI etc.

These configuration should be done by the products experts as it may cause the high CPU usage and can lead to overall slowness of the server so we suggest to support team for the optimal configuration.
