monitor disk io

[obi3]

Hello everyone,
I have just installed proxmox for first time and first thing i have tried to do is monitor disk io.
I tried by parsing the output of iostat and ingesting the data in influx ... so this is what i get
i can't find out why i have constant io traffic of around 45MB , I have only 1 container running and no io consuming services on it.Also i tried to create 1.2GB file and it has been reported as you can see on the graph. Thank you

Eg. background services will log data to syslog and other logfiles. Check under /var/log, it should have grown.
