In this post, you’ll learn what causes high series cardinality in a time series database and how to locate and eliminate the culprits. First, for those of you just encountering this concept, let’s define it: The number of unique database, measurement, tag set, and field key combinations in an InfluxDB instance. Because high series cardinality is a primary driver of high memory usage for many database workloads, it is important to understand what causes it and how to resolve it.

Have you ever had to saw through a board by hand? I had to finish a partial cut by hand the other day while building a new mantle for my fireplace. It’s slow and difficult, and it often results in a lesser quality cut than one done with a power tool. It’s good exercise, though! We should all have to do it at least once so we appreciate our power tools more.

Cyberthreats have been coming at us from the left, right, and center. The number of cyberattacks is forever on the rise, and companies need to keep ramping up their security measures to protect themselves. It’s important that these measures cover every aspect of a network environment. To understand why monitoring your whole environment is so important, let’s take a look at what an attacker might do once they get inside your organization.

Auth0 provides identity as a service (IDaaS), allowing you to secure your apps and APIs without having to write your own authorization code. Auth0 can work with social identity providers (IdP) like Google and Facebook so your users can access your app by using their existing accounts for authentication. You can also use an existing enterprise identity provider (e.g., LDAP) to allow your users to leverage single sign-on (SSO) across multiple apps.

Have you ever heard of Node.js async hooks module? If the answer is no, then you should get familiar with it. Even though it’s new stuff (released along with Node.js 9) and the module is still in experimental mode, which means it’s not recommended for production, you should still get to know it a bit better. In short, Node.js async hooks, more specifically the async_hooks module, provides a clear and easy-to-use API to track async resources in Node.js.

Adopting Kubernetes and service-based architecture can bring many benefits to organizations – teams move faster and applications scale more easily. However, visibility into cloud costs is made more complicated with this transition. This is because applications and their resource needs are often dynamic, and teams share core resources without transparent prices attached to workloads.

Logstash has a number of helpful plugins. We’ve covered the mutate plugin in great detail here, as well as Logstash grok, but it was time to go over some of the others. Here, the Logstash Prune Filter will get its due attention. Its existence owes to the need to remove fields according to select blacklists or whitelists of field names and their associated values. Put more curtly, it prunes the excess branches (fields) in your garden (your data).
