How to Monitor Redis Performance

The name Redis is derived from the phrase “REmote DIctionary Server.” The project is open-source, and is one of the most popular key-value databases in use today. The Redis dataset is stored entirely in memory, which allows it to function exceptionally fast, and the data is written to disk periodically to support persistence of the data if the memory is lost.

When using Redis as a data source for an application, it is important to ensure that the service remains both healthy and stable. The best way to do this is by developing and instituting a comprehensive monitoring plan. Development of such a plan and its implementation is the topic of this article. We’ll discuss what key metrics should be included in the plan and why, and we’ll conclude with a walkthrough of how to configure Redis to report its metrics to Librato, and how to view those metrics through a custom dashboard.

Continual monitoring in the face of cloud storage failure



Continual monitoring in the face of cloud storage failure

On February 28th, 2017, many companies experienced the effects of the failure of components of the S3 object storage service offered by Amazon Web Services (AWS). Since, according to the Synergy Research Group, AWS owns more than 40% of the public cloud market, this outage potentially affected a large number of systems hosts in the cloud. Because Librato is built on AWS and relies on services like S3, or services dependent on S3, we were not immune to the S3 downtime either. However, because our infrastructure is built with the Cockcroft quote above in mind, we were able to weather the storm with minimal disruption to our customers, and absolutely no loss of customer data.
