1. Proposed title of this feature request Disk Availability Tracking in Metrics 3. What is the nature and description of the request? Customer would like a way to track disk usage in the metrics. Customer is prioritizing ephemeral disk usage of docker pods, but would also find persistent volume tracking to be useful. 4. Why does the customer need this? (List the business requirements here) It is important to be able to track disk usage to not run out, especially as running out of disk space can cause issues that require more than just throwing extra storage on. This is important for stability reasons and to ensure that there is no downtime. 5. How would the customer like to achieve this? (List the functional requirements here) Add tracking of disk usage as well as graphs in the console as with mem and cpu 7. Is there already an existing RFE upstream or in Red Hat bugzilla? No BZ, but there is https://trello.com/c/lBWEQiHr/269-3-r-d-gather-pv-disk-usage-metrics-heapster-epic-ois-met-ux
Are you looking for just how much disk space is being used? eg using 10Gi of space out of 120Gi? Or are you looking for something like IOPS? Or something else?
It appears the customer is looking for information on how much disk space is currently being used by the container either via PV or ephemeral storage; they make no mention of IOPS or etc, and seem to be focused on current disk allocation.
Hello, Do we have a target version/date for this?
In 3.5: We have a few metrics here with regards to filesystem. We can see the usage and limit for each pod and each volume in the pod (note: we don't have PV usage metrics yet) We can also get the usage and limit values for the nodes themselves. In 3.4: There are some of preliminary filesystem metrics in here as well, but not to the extent that they are in 3.5 Note that none of these metrics are being displayed in the console anywhere and are only currently available via the Hawkular Metrics REST API. PRs have been opened for the console to start graphing this information.

Any update?
*** Bug 1548249 has been marked as a duplicate of this bug. ***
any update on this?
I'm also curious about an update for this.
It is better to set a Target Release, then would be easy to verify
Created attachment 1538368 [details] Disk Utilisation Usage data
See the picture in Comment 39, we can show the Disk usage data in grafana, and could also check volume info from prometheus kubelet_volume_stats_used_bytes -> used bytes, kubelet_volume_stats_available_bytes -> available bytes There is one Bug 1680517 on openstack now, but works with aws/gce, it does not related to this RFE, set it to VERIFIED. cluster monitoring images: v3.11.88
