The sections below describe the metrics supported by SUSE OpenStack Cloud Monitoring:
Standard metrics for general monitoring of servers and networks.
Additional metrics for monitoring specific servers and services.
SUSE OpenStack Cloud Monitoring supports the following standard metrics for monitoring servers and networks. These metrics usually do not require specific settings. The metrics are grouped by metrics types. Each metrics type references a set of related metrics.
Metrics on CPU usage, e.g. the percentage of time the CPU is idle when no I/O requests are in progress, or the percentage of time the CPU is used at system level or user level.
Metrics on disk space, e.g. the percentage of disk space that is used on a device, or the total amount of disk space aggregated across all the disks on a particular node.
Metrics on the average system load over different periods (e.g. 1 minute, 5 minutes, or 15 minutes).
Metrics on memory usage, e.g. the number of megabytes of total memory or free memory, or the percentage of free swap memory.
Metrics on the network, e.g. the number of network bytes received or sent per second, or the number of network errors on incoming or outgoing network traffic per second.
These metrics are configured automatically on all machines and nodes that have
the monasca-agent role assigned. This applies not only to
network.yaml but also to all metrics covered in this chapter.
