Complete Guide to Nginx Monitoring with Telegraf, Prometheus, and Grafana

To effectively monitor Nginx using Telegraf, Prometheus, and Grafana, first enable the Nginx status page. Next, set up Telegraf to collect these metrics and output them in a Prometheus-friendly format. Then, configure Prometheus to scrape data from Telegraf. Finally, use Grafana to view the collected metrics.

This article will guide you on how to get Nginx Web Server metrics and visualize them. The main goal is a quick deployment and configuration using well-known open-source projects like Grafana, Prometheus, and Telegraf.

Your Guide for Patching Elastic Search!

What is Patching?

A patch is a set of updates to a server or its supporting data designed to update, fix and improve, including fixing security vulnerabilities and other bugs. They may be applied to program files on a storage device or in computer memory. Patches may be permanent or temporary. 
In a brief overview, you need to perform the following tasks for patch management: 
 1. Create a patch catalog.
 2. Analyze the target to determine the patches that need to deploy.
 3. Deploy the required patches to targets requiring remediation.
 4. Analyze the targets again to ensure each server has the correct patch.

AWS LAMBDA – Here’s Everything You Need to Know!

What is Serverless?

To understand what AWS Lambda is, we have to first understand all about serverless architecture. The serverless architecture is a way to build and run applications and services without having to manage infrastructure. Your application still runs on servers. When you run a serverless application, you get the benefit of not worrying about OS setup, patching, or scaling of servers that you would have to consider when you run your application on a physical server.

Serverless applications or platforms have four characteristics:

  • No server management
  • Flexible scaling
  • No idle capacity
  • High availability

How to fix error “[SSL: CERTIFICATE_ VERIFY_FAILED] certificate verify failed” (_ssl.c:727)

If you’re encountering the “SSL: CERTIFICATE_VERIFY_FAILED” error while working with Python’s requests library, don’t worry. Typically, this issue occurs because you need to update your CA certificates, set up custom trust paths, or avoid development shortcuts that can lead to security vulnerabilities.

Understanding SSLCertVerificationError

While collaborating on a hybrid cloud project with a client in the banking sector, we encountered a problem:
