influxdb-grafana

Getting Started

  • InfluxDB:
  • Grafana:

  • SQL Server:
    • Create a login - with a strong password - in every SQL Server instance you want to monitor:
     USE master; 
     GO
     CREATE LOGIN [linuxuser] WITH PASSWORD = N'mystrongpassword';
     GO
     GRANT VIEW SERVER STATE TO [linuxuser]; 
     GO
     GRANT VIEW ANY DEFINITION TO [linuxuser]; 
     GO

How to use GO code

  • Run in background: go run influxdb-sqlserver.go &
  • Build in the current directory: go build influxdb-sqlserver.go
  • Install in $GOPATH/bin: go install influxdb-sqlserver.go
