Description

Just like "network", "CPU" and "MEMORY", DISK IO information (READ/WRITE IOPS/THROUGHPUT) would be useful for quick inspection of (busy) VM's. Per DISK IO graphs would give the best insight in wich part of the VM is doing most of the IO. An item on the "Dashboard" of amount of DISK IO would be nice also.

  • Priority changed from None to High

Ok, moving it to the backlog with High Priority. We need to setup VM probes for all the hypervisors to get the DISK/IO info.

During the OpenNebula conference several presentations made note of the needs for DISK (IO) operations because of performance issues in their environment (user VM's hammering storage layer). I have at least spoken with 4 different OpenNebula users that made customs tools / scripts to collect data from libvirt to address this issue ... there seems to be a clear demand for this feature :-).

Seems to be related to #2768 (Ruben S. Montero: "This may require, update accounting schema as well as monitoring probes") ... if this information is to be used in accounting / showback.

+1, this feature would be great to have in OpenNebula. We are currently using https://github.com/fasrc/nebula-ceph-diamond-collector for monitoring vm disks on ceph using rbd performance counters

#14 Updated by Ruben S. Montero almost 5 years ago

Cool, we'll take a look at it. We need to generalize the framework to gather input from other storage sources LVM, FS... but this is something we can use to extend the VM monitoring.

#16 Updated by Miguel Ángel Álvarez Cabrerizo over 4 years ago

Added information for vCenter driver. The following metrics are used from vCenter's PerfManager using real-time data. vCenter statistics level must be set to 2 for 5 minute (Settings -> Statistics) in order to get disk IO info:

- virtualDisk.read to get diskrdbytes. vCenter provides an average in kilobytes/s so data retrieved will be an approximation.
- virtualDisk.write to get diskwriops. vCenter provides an average in kilobytes/s so data retrieved will be an approximation.
- virtualDisk.numberReadAveraged to get diskrdiops
- virtualDisk.numberWriteAveraged to get diskwriops
