How Metric Collections Works

VirtualWisdom performs the following multi‐step process to collect metrics.

The VirtualWisdom InfiniBox translator aggregates together live performance data (1 seconds data) and some point-in-time values (capacity etc) to populate all of the VirtualWisdom metrics. The live performance data requires an InfiniBox collector be set up on the InfiniBox array. These InfiniBox collectors track approximately the last 30 seconds of data at 1 second granularity. The VirtualWisdom InfiniBox translator therefore must connect to the array every 15 seconds (+/-) to pull the latest data before it is discarded. This live data is stored internally in the translator. Every 2 minutes the live data is batched into 30 second buckets and sent into VirtualWisdom for processing. This results in data arriving every 2 minutes with a granularity of 30 seconds.

During collection if the VirtualWisdom InfiniBox translator detects a problem with the InfiniBox collectors it will attempt to recreate the translators in order to maintain consistent data collection.
