Elastic

Introduction In this gist we will quickly spin a sample Kubernetes cluster and deploying the nginx pod. Additionally, we will implement monitoring using Elastic. Setup K8s cluster Cluster architecture 3 Node cluster Machine - Centos7, 4GB RAM kube1.local - Control plane node kube2.local - worker node kube3.local - worker node Here I am setting hostname kube1.local, kube2.local, kube3.local. Login into all of the servers and perform below command on all three nodes. ...

Introduction Bring logs, metrics, and traces from your Kubernetes cluster and the workloads running on it into a single, unified solution. Elastic observability gives better visibility on your kubernetes ecosystem where you can monitor your pods, services, workload etc. Use a centrally managed Elastic Agent to gain visibility into your Kubernetes deployments on EKS, AKS, GKE or self-managed clusters.

In this blog, we will see how you can quickly setup ELK (Elasticsearch, Logstash, Kibana) stack to receive the HTTP webhook. Mostly ELK stack is known for logging purposes. But Elastic stacks are much more beyond the logging use case. Elastic provides Search, Observability & Security you can check more on this with official documentation. What is Webhook ? Webhook enables the two programs to communicate or transfer the data with the help of callback functions / hooks. Now in the modern tech world it is also known as Reverse API, Push API etc. Mostly it is used to send small amounts of data from source to destination. It is a one way data transfer procedure. It works over the HTTP protocol using REST API. It is simple like client and server communication. Most of the saas allow you to integrate their product with your system with the help of APIs and Webhook only. E.g. Slack and discord allows you to push messages with the help of webhooks. To accept the webhook event, You need to expose one HTTP endpoint lets say ...

What this talk is all about ? Elastic Stack (Elasticsearch, Logstash, Kibana and Beats) is such a platform which is built for scalability, performance and “You know… for Search”. When you have a system which scales to the horizons of your data, helps you in your data quest, shows you insights - imagine what you can do with it.

Introduction As a developer, you need to log everything it may be info, error or debug logs, etc. There are multiple types of log formats like Common log, JSON log, etc. and there are already solutions available in an elastic stack like filebeat to read JSON logs and push them to elasticsearch. There can be cases where you need to log the data according to your convenience which will not be any standard log format. Or sometimes you just need to dump the log in an unstructured way but you need to have it in a structured format if you want to analyze those. ...
