mongodb. I want to get disk.device.usage in percentage.

2018-01-20 01:35:55 -0600 commented answer enable “memory.usage”, “disk.device.usage” meter

requirement is to get the disk.device.usage in percentage.I have no idea how to do that in pipeline.yaml. But i have done it for memory usage . I have tried same for disk.device.usage and it is not working. disk.device.usage is not coming in the command $ ceilometer meter-list using mongodb

2018-01-18 08:25:04 -0600 asked a question disk used in percentage to be polled from application

What is the difference between disk.usage and disk.device.usage ? pls explain with example

How to measure the percentage of disk used by instance ? I want to add to ceilometer to poll(every 10 minutes) from application . i.e i have to get disk used in percentage. Following meters are there in ceilometer:- disk.allocation
disk.capacity
disk.ephemeral.size
disk.read.bytes
disk.read.bytes.rate
disk.read.requests
disk.read.requests.rate
disk.root.size
disk.usage
disk.write.bytes
disk.write.bytes.rate
disk.write.requests
disk.write.requests.rate

how to configure in pipeline.yaml to get disk used in percentage .

2018-01-18 08:25:04 -0600 answered a question enable “memory.usage”, “disk.device.usage” meter

I have configured memory usage in pipeline.yaml sources:

[...]
- name: memory_source
      interval: 600
      meters:
          - "memory.usage"
      sinks:
          - memory_sink
sinks:
[...]
- name: memory_sink
      transformers:
          - name: "arithmetic"
            parameters:
                target:
                    name: "memory_usage"
                    unit: "%"
                    type: "gauge"
                    expr: "100 * $(memory.usage) / ($(memory.usage).resource_metadata.memory_mb)"

However I am unable to get disk.device.usage

Thanks Bernd. memory.usage and disk.device.usage is not configured in pipeline.yaml or nova.conf. I want to know, how to configure those parameters and enable it at openstack level. so that i can query from application for every 600 sec. as of now I can query cpu_util .

2018-01-10 01:33:43 -0600 asked a question enable “memory.usage”, “disk.device.usage” meter

How to enable “memory.usage”, “disk.device.usage” in openstack (ceilometer/nova)

need to get those meter for every 10 minutes (600 secs)

Details :-

Compiled against library: libvirt 1.2.17 Using library: libvirt 1.2.17 Using API: QEMU 1.2.17 Running hypervisor: QEMU 2.6.0

I am new to openstack . Hence could you please post detailed answer/configuration.
