# SQL Server plugin
This sqlserver plugin provides metrics for your SQL Server instance.
It currently works with SQL Server versions 2008+.
Recorded metrics are lightweight and use Dynamic Management Views supplied by SQL Server:
```
Performance counters : 1000+ metrics from sys.dm_os_performance_counters
Performance metrics : special performance and ratio metrics
Wait stats : wait tasks categorized from sys.dm_os_wait_stats
Memory clerk : memory breakdown from sys.dm_os_memory_clerks
Database size : databases size trend from sys.dm_io_virtual_file_stats
Database IO : databases I/O from sys.dm_io_virtual_file_stats
Database latency : databases latency from sys.dm_io_virtual_file_stats
Database properties : databases properties, state and recovery model, from sys.databases
OS Volume : available, used and total space from sys.dm_os_volume_stats
CPU : cpu usage from sys.dm_os_ring_buffers
```
You must create a login on every instance you want to monitor, with following script:
```SQL
USE master;
GO
CREATE LOGIN [telegraf] WITH PASSWORD = N'mystrongpassword';
GO
GRANT VIEW SERVER STATE TO [telegraf];
GO
GRANT VIEW ANY DEFINITION TO [telegraf];
GO
```
