Yes you can monitor the network traffic in the VM. You need the following tools to be installed

Telegraf (On VM) - A tool to capture the monitoring metrics from the VM

Add the following to your telegraf.conf to capture the network traffic


InfluxDB(On Local Server) - A Database to store the network metrics from Telegraf.

Grafana(On Local Server) - A dashboard to display the metrics from InfluxDB database

I hope this answer can help you

Hi thanks for posting the question.

Follow this API documentation to specify the volume_type while creating a volume.,create-consistency-group-snapshot-detail,update-volume-type-detail,create-volume-detail#create-volume

Below is an example from the document for your reference:

    "volume": {
        "size": 10,
        "availability_zone": null,
        "source_volid": null,
        "description": null,
        "multiattach ": false,
        "snapshot_id": null,
        "name": null,
        "imageRef": null,
        "volume_type": null,
        "metadata": {},
        "source_replica": null,
        "consistencygroup_id": null
    "OS-SCH-HNT:scheduler_hints": {
        "same_host": [

I hope that clears your doubt

Unfortunately Cassandra is not supported in ceilometer.

Its not mentioned in the documentation:

Observe the repo also:

There have been attempts to add a cassandra driver support but patches are abandoned and they are not merged

Take a look at blueprint for the same:

I hope this answers your question
