The success of your website lies in how satisfied your users are with it. To help ensure the quality of your user experience, Google uses various signals from a web page. The three Core Web Vitals are some of the most important ones. In this article, I’ll talk about what each Core Web Vital means and how to optimize them to deliver a better user experience.

Kubernetes is first and foremost an orchestration engine that has well-defined interfaces that allow for a wide variety of plugins and integrations to make it the industry-leading platform in the battle to run the world's workloads. From machine learning to running the applications a restaurant needs, you can see that just about everything now uses Kubernetes infrastructure. All these workloads, and the Kubernetes operator itself, produce output that is most often in the form of logs.

As we at Splunk accelerate our cloud journey, we’re often faced with the decision of when to use logs vs metrics — a decision many in IT face. On the surface, one can do a lot by just observing logs and events. In fact, in the early days of Splunk Cloud, this is exactly how we observed everything. As we continue to grow, however, we find ourselves using a combination of both. This post lays out the overall difference in logs and metrics and when to best utilize each.

Prometheus is a widely utilized time-series database for monitoring the health and performance of AWS infrastructure. With its ecosystem of data collection, storage, alerting, and analysis capabilities, among others, the open source tool set offers a complete package of monitoring solutions. Prometheus is ideal for scraping metrics from cloud-native services, storing the data for analysis, and monitoring the data with alerts.

When it comes to centralizing logs to Elasticsearch, the first log shipper that comes to mind is Logstash. People hear about it even if it’s not clear what it does: – Bob: I’m looking to aggregate logs – Alice: you mean… like… Logstash? When you get into it, you realize centralizing logs often implies a bunch of things, and Logstash isn’t the only log shipper that fits the bill.

In an earlier blog post, Log monitoring and unstructured log data, moving beyond tail -f, we talked about collecting and working with unstructured log data. We learned that it’s very easy to add data to the Elastic Stack. So far the only parsing we did was to extract the timestamp from this data, so older data gets backfilled correctly. We also talked about searching this unstructured data toward the end of the blog.
