[PATCH 0/6] Add BlkIO and CPU/mem stat API implementations for lxc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch set adds block io, memory and domain cpu statistics API
slot implementations to the LXC driver, in order to get linux
container monitoring and accounting a bit closer to qemu standards.

The last patch is a tad quirky (happy to hear suggestions on
alternative ways), in that it widens the permissible value set
at the .domainBlockStats slot: for lxc guests, it is relatively
likely to have zero disk devices, since host filesystems can be
used via passthrough bind mounts. Therefore, passing the null ptr
or the zero-length string as device path, is interpreted as 'return
summary stats for the entire domains's block io'.

Thorsten Behrens (6):
  Add util virCgroupGetBlkioIo*Serviced methods.
  Implement domainMemoryStats API slot for LXC driver.
  Make qemuGetDomainTotalCPUStats a virCgroup function.
  Implement domainGetCPUStats for lxc driver.
  Implemet lxcDomainBlockStats for lxc driver
  Widening API change - accept empty path for virDomainBlockStats
