Logging and monitoring

OpenStack clouds require appropriate monitoring platforms to catch and manage errors.

Note

We recommend leveraging existing monitoring systems to see if they are able to effectively monitor an OpenStack environment.

Specific meters that are critically important to capture include:

• Image disk utilization
• Response time to the Compute API

Logging and monitoring does not significantly differ for a multi-site OpenStack cloud. The tools described in the Logging and monitoring chapter of the Operations Guide remain applicable. Logging and monitoring can be provided on a per-site basis, and in a common centralized location.

When attempting to deploy logging and monitoring facilities to a centralized location, care must be taken with the load placed on the inter-site networking links.
