Visual presentation of metrics reflecting lifecycle events of software artifacts

A system comprising:

• a memory;
• and
• a processing device, coupled to the memory, wherein the processing device is configured to:
• receive a data processing rule specifying an aggregation operation to be performed on raw data items reflecting lifecycle events associated with a software artifact, the data processing rule further specifying an event type, an event aggregation parameter and an event filtering time range, wherein the event aggregation parameter is provided by an identifier of a code base associated with the software artifact;
• receive, from one or more data collection agents, a plurality of raw data items;
• select, from the plurality of raw data items, one or more raw data items comprising the specified event aggregation parameter and specifying lifecycle events of the specified event type falling within the event filtering time range;
• produce, by applying the data processing rule to the selected raw data items, a plurality of values of a metric reflecting lifecycle events associated with the software artifact;
• and
• cause the values to be graphically represented using a graphical user interface (GUI).

A computer-readable non-transitory storage medium comprising executable instructions that, when executed by a first computer system, cause the computer system to perform operations comprising:

• receiving a data processing rule specifying an aggregation operation to be performed on raw data items reflecting lifecycle events associated with a software artifact, the data processing rule further specifying an event type, an event aggregation parameter and an event filtering time range, wherein the event aggregation parameter is provided by an identifier of a code base associated with the software artifact;
• receiving, from one or more data collection agents, a plurality of raw data items;
• selecting, from the plurality of raw data items, one or more raw data items comprising the specified event aggregation parameter and specifying lifecycle events of the specified event type falling within the event filtering time range;
• producing, by applying the data processing rule to the selected raw data items, a plurality of values of a metric reflecting lifecycle events associated with the software artifact;
• and
• causing the values to be graphically represented using a graphical user interface (GUI).
