EFK Stack Architecture
The data from the different sources are stored in the pods of each cluster, which are collected by Fluentd. Later it transforms and ships to Elasticsearch backend. In Elasticsearch data are analyzed and later it moves to the Kibana and there the visualization of data takes place.
Similarly one may ask, how can I run fluently?

Simply so, how does Prometheus work in Kubernetes?
Prometheus uses Kubernetes APIs to read all the available metrics from Nodes, Pods, Deployments, etc. For this reason, we need to create an RBAC policy with read access to required API groups and bind the policy to the monitoring namespace.
How install fluent in Kubernetes?

- Step 1: Grant Permissions to Fluentd. Fluentd will be collecting logs both from user applications and cluster components such as kube-apiserver and kube-scheduler , so we need to grant it some permissions. …
- Step 2: Deploy a DaemonSet.

What is DaemonSet in Kubernetes?
A DaemonSet ensures that all (or some) Nodes run a copy of a Pod. As nodes are added to the cluster, Pods are added to them. As nodes are removed from the cluster, those Pods are garbage collected. Deleting a DaemonSet will clean up the Pods it created.
What is Efk used for?
EFK is a suite of tools combining Elasticsearch, Fluentd and Kibana to manage logs. Fluentd will collect the logs and send it to Elasticsearch. This latter will receive the logs and save it on its database. Kibana will fetch the logs from Elasticsearch and display it on a nice web app.
What is Fluentd in Kubernetes?
Fluentd. Kubernetes Fluentd. Kubernetes provides two logging end-points for applications and cluster logs: Stackdriver Logging for use with Google Cloud Platform and Elasticsearch. Behind the scenes there is a logging agent that take cares of log collection, parsing and distribution: Fluentd.
What is Kibana Efk?
Kibana allows you to explore your Elasticsearch log data through a web interface, and build dashboards and queries to quickly answer questions and gain insight into your Kubernetes applications. In this tutorial we’ll use Fluentd to collect, transform, and ship log data to the Elasticsearch backend.
What is the difference between Fluentd and fluent bit?
Fluentd was designed to handle heavy throughput — aggregating from multiple inputs, processing data and routing to different outputs. Fluent Bit is not as pluggable and flexible as Fluentd, which can be integrated with a much larger amount of input and output sources.
What is the difference between Grafana and Kibana?
Grafana’s design for caters to analyzing and visualizing metrics such as system CPU, memory, disk and I/O utilization. The platform does not allow full-text data querying. Kibana, on the other hand, runs on top of Elasticsearch and is used primarily for analyzing log messages.
What is the role of Fluentd?
Fluentd is an open source data collector, which lets you unify the data collection and consumption for a better use and understanding of data.
