Summary | {{ $value }} VCPUs on the {{ $labels.hostname }} node (>=
{{ cpu_minor_threshold * 100 }}% ) are used. |
Raise condition | label_replace(system_load15, "hostname", "$1", "host", "(.*)") > on
(hostname) openstack_nova_vcpus * 0.85 |
Description | Raises when the hypervisor consumes more than 85% of the available VCPU
(the average load for 15 minutes), according to the data from Nova API
and the load average from /proc/loadavg on the appropriate node. For
details, see Hypervisors.
