Challenge
Starting with version 9, Veeam ONE database server shows high IOPS usage of approximately 700-800 operations per second with regular spikes exceeding 2500 operations every 5 minutes.
Cause
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.
Solution
This behavior is by design. Possible solutions to balance the load include:
- Migrating Veeam One database to a dedicated datastore to minimize the impact on other applications
- Changing the Scalability mode as per KB2017
