DevOps is the new culture and methodology with several benefits and it shapes the change in the organization by combining development and operations. DevOps consists of continuous development, continuous testing, configuration management, continuous integration, continuous deployment, and continuous monitoring. In this article, we will discuss what is continuous monitoring, what are its benefits, why it is required, and the top 10 DevOps monitoring tools.
Before we go there we need to know what DevOps life cycle management consists of. DevOps Life Cycle Management consists of phases that include plan, code, build, test, release, deploy, operate, and monitor. As you see, the monitoring is one of the important parts of DevOps life cycle management. To achieve the DevOps Life Cycle Management there are lot of tools for each of the phases. We will be discussing the top 10 DevOps tools for monitoring in this article.
What is DevOps monitoring?
DevOps monitoring is monitoring the applications, network, servers, and other digital assets for performance, health, user transactions, security, loads, bugs, alerts, errors and helps to ensure their smooth functioning. The proactive monitoring helps in monitoring the digital assets in a way that simulates the real user’s environment on the assets. This helps to know the errors and other parameters beforehand in a pre-production environment even before going live.
The organization also monitors the digital assets in the production environment to figure out the issues and problems that may affect the users accessing the digital assets. Implementing the monitoring tools in the DevOps environment acts as an early warning system that provides us with sufficient time to rectify or correct the awkward situation. In the traditional environment, the monitoring tools were deployed in the late stages of the SDLC that is in the production environment, however, in the DevOps life cycle management, the monitoring tools are used to find out the deviance early in the cycle at planning and development stage itself.
Benefits of DevOps monitoring tools
Some of the goals of DevOps monitoring is to shift left in the DevOps life cycle and do monitoring at the development stage itself. This along with proactive monitoring helps to find the defects and deviance at the early stage itself. The 3 things that monitoring is needed in the early stages are as follows,
Reuse – Create new monitors instantly by reusing the AlertSite's OpenAPI, Selenium scripts, and Soap UI test cases. This will have the following benefits; it saves efforts, time, and money. Reusing assets also supports consistency and standardization across the organization in multiple departments.
Monitor during the pre-production – When you are developing the test cases use the monitors along with the test cases to start the monitoring earlier. This helps a lot in pre-production by identifying the issues earlier.
Use REST API's – The AletSite's REST API can be used to create the monitors at the build and deployment stages.
Monitoring in the Pre-production – This helps to find out issues early and make the changes early even before going into production. It also helps in such a way that the new changes in the production will not destroy the monitors in the production environment. It also gives the information or insight into the test environment itself.
The monitoring tools in the DevOps environment helps in 4 ways to collaborate, automate, configure, and share. Monitoring early in the environment helps to work collaboratively with other team members. By nature, the pre-production environment is an automated process and helps reduces efforts manually and reduces error-prone routine jobs. Configuring the monitor’s scripts helps in reusing and reducing errors. By sharing the information among the different departments of the DevOps life cycle helps to enhance the DevOps culture and its benefits.
