Monitoring, Logging, and Cost Estimating
Dan Sullivan · 2019
This Chapter offers information on the Stackdriver, a GCP service for resource monitoring, logging, tracing, and debugging. Stackdriver is a service for collecting performance metrics, logs, and event data from our resources. Metrics include measurements such as the average percent CPU utilization over the past minute and the number of bytes written to a storage device in the last minute. Metrics are defined measurements on a resource collected at regular intervals. Metrics return aggregate values, such as the maximum, minimum, or average value of the item measured, which could be CPU utilization, amount of memory used, or number of bytes written to a network interface. Stackdriver Monitoring allows you to define alerts on metrics, such as CPU utilization, so that you can be notified if part of your infrastructure is not performing as expected. Stackdriver Logging collects, stores, and manages log entries. Log data that needs to be stored more than 30 days can be exported to Cloud Storage, BigQuery, or Cloud Pub/Sub. Cloud Trace provides distributed tracing services to identify slow-running parts of code. Cloud Debug provides for creating snapshots of running code and injecting log messages without altering source code.
