[1/2] git commit: updated refs/heads/statscollector-graphite to
9ba50f3
Repository: cloudstack
Updated Branches:
refs/heads/statscollector-graphite 621156ca5 -> 9ba50f30e (forced update)
CLOUDSTACK-7641: Do not always ask libvirt to refresh a storage pool
On larger (especially RBD) storage pools this can take a lot of
time slowing operations like creating volumes down.
The getStorageStats command will still ask a pool to be refreshed so
that the management server has accurate information about the storage pools.
On larger deployments, with thousands of volumes in one pool, this should
significantly improve storage related operations

[2/2] git commit: updated refs/heads/statscollector-graphite to
9ba50f3
Posted by wi...@apache.org.
CLOUDSTACK-7583: Send VmStats to Graphite host when configured
This allows external processing of VmStats information without using
the usage server of CloudStack
Statistics are being send to Graphite using UDP and not TCP.
UDP is used to prevent the management server waiting for TCP timeouts
when the Graphite server is unavailable
