Described are techniques for processing event occurrence. A first notification may be received regarding a first occurrence of a first event. Responsive to receiving the first notification, first processing may be performed that includes mapping the first event to a first profile, and performing second processing using the first profile to collect first data regarding the first occurrence of the first event.

Event triggered data collection

A technique for logging events in a data storage system involves designating one subset of storage processors of the data storage system as clients that generate log entries and another subset of the storage processors as servers that receive log entries. Only one server is active at a time. The active server receives the generated log entries from the clients and persists the log entries to a centralized log store. Clients assign first timestamps to the log entries based on locally accessible clocks. The active server receives the log entries, including the first timestamps, from the clients and applies second timestamps based on a clock accessible to the server. As the second timestamps are consistent across the different clients, the second timestamps can be applied to correct misalignments in time among the log entries received from the clients.

Centralized logging for a data storage system

Disclosed is an approach for presenting RDF data as a set of relational views. By presenting the RDF data as relational views, this permits integrated access to the RDF-based data from existing relational database tools, such as by asserting SQL queries against the relational views. One or more classes are identified within the RDF data, wherein a relational view of the set of the relational views maps properties relating to a particular class.
