As a real-time monitoring solution, Veeam ONE actively performs input-output operations against its database. Version 9 uses modified monitoring engine. Data collection and database data writing procedures have been overhauled, increasing the list of collected performance counters, the number of operations per second in regards to SQL database and WMI. The data are collected and written to the database using sophisticated algorithms for processing performance data and alarms.
The aforementioned processes cause relatively stable IOPS index with regular 5-minute spiking that references to the frequency with which bulk insert into the database takes place.
