Kubernetes audit logs contain detailed information about every request to the Kubernetes API server and are critical to detecting misconfigurations and vulnerabilities in your clusters. But because even a small Kubernetes environment can rapidly generate lots of audit logs, it’s very difficult to manually analyze them.

For public IPs, it is possible to create tables that will specify which city specific ranges of IPs belong to. However, a big portion of the internet is different. There are company private networks with IP addresses of the form 10.0.0.0/8, 172.16.0.0/12 or 192.168.0.0/16 scattered in every country in the world. These IP addresses tend to have no real information for the geographic locations.

Whether you’re trying to troubleshoot a problem, defend against attacks, or simply optimize your environment, event logs are your best source of information. More than that, not logging or ignoring your logs is like not checking your blindspot when you’re changing lanes—sooner or later you’re going to seriously regret it because the effects will be disastrous.

Cloud Logging is a popular tool to help developers, operators, and other users identify and find the root cause of issues in their infrastructure. With features like the Logs Explorer, you can quickly and efficiently retrieve, view, and analyze logs. To help you get the most out of your logs, we’re excited to introduce suggested queries in Cloud Logging to help highlight important logs, so you can start analyzing and troubleshoot issues quickly.

Observability is an indispensable concept in continuous delivery, but it can be a little bewildering. Luckily for us, there are a number of tools and techniques to make our job easier! One way to aid in improving observability in a continuous delivery environment is by monitoring and analyzing key metrics from builds and deploys. With tools such as Prometheus and their integrations into CI/CD pipelines, gathering and analysis of metrics is simple. Tracking these things early on is essential.

Javascript is a pretty prolific programming language, used daily by people visiting any number of websites and web applications. NodeJS, it’s server-side version, is also used all over the place. You’ll find it deployed as full application stacks to functions in things like AWS Lambda, or even as IoT processes with things like Johnny Five. So when we think about Observability in the context of a nodejs stack, how do we set it up and get the information flowing?

Whether you are planning to use Graylog for security and threat hunting, IT Operations analysis and reporting, or any other use case, getting your logs into Graylog is essential. The process of log collection is sometimes a daunting task, especially if you are planning to collect massive amounts of data. But if you take a minute to answer some key questions before you begin, you can transform the log collection task from daunting to smooth sailing. Here we go with the questions...

Keeping track of what’s going on in Kubernetes isn’t easy. It’s an environment where things move quickly, individual containers come and go, and a large number of independent processes involving separate users may all be happening at the same time. Container-based systems are by their nature optimized for rapid, efficient response to a heavy load of requests from multiple users in a highly abstracted environment and not for high-visibility, real-time monitoring.
