[SOLVED] netin seems to spike every 7 to 10 mins wonder if this is normal ?

[Spirog]

I am running latest version of Proxmox7.1
and everytime I look at netin in the below screenshot I see spikes right around 7 to 10 mins.

Just wondering if this is this normal ?


is seems to be the same when looking at my VM's under this node.

how can I find out what is creating the spikes every 7-10 mins.




PS I have edited the IP address below. this is not my IP address for security but resembles the setup.

Thank you in advance for your help

- if you need any more info please let me know I can get it for you.


- another question?

could this possibly be from a VM on this node> maybe a running cron job every 10 or so mins?

Does the node shows activity for all of the VM under it in netin graph?

- just want to make sure its not anything with my network configuration or my server host

thanks again for your help in advance

Hi,

could this possibly be from a VM on this node> maybe a running cron job every 10 or so mins?

yes, It looks like a cron job in your host/VM in your cluster running every 7-10 min

Does the node shows activity for all of the VM under it in netin graph?

Yes.
