Prometheus was designed with 4 main requirements in mind 1: To emphasize this and clarify the project's governance structure, Prometheus joined the Cloud Native Computing Foundation in 2016 as the second hosted project after Kubernetes. It is now a standalone open source project and maintained independently of any company. The Prometheus website goes on to say that: Since its inception in 2012, many companies and organizations have adopted Prometheus, and the project has a very active developer and user community.Īs SoundCloud moved towards microservices they needed to monitor thousands of running services and as their current monitoring systems had too many limitations they invented Prometheus. (.) an open-source systems monitoring and alerting toolkit originally built at SoundCloud. Deity? Prometheus! Copied from the Prometheus website, they describe it as: My personal preference goes out to Greek deity that stole fire from Mount Olympus and brought it to us. For example, you can use Nagios, Zabbix or Prometheus. You have different options depending on what you want to monitor. You not only have to deal with a bunch of more servers, you also have to deal with more (micro)services. In today's age of microservices, that whole monitoring thing is getting more and more complex. That’s it for now! You can share your thoughts about Nodejs application monitoring using PM2, with us via the feedback form below.In the age of large monolithic apps and app servers, it was not too difficult to monitor the status of your application as well as some more detailed monitoring of transactions. To remove pm2-server-monit from your server, run the following command: # pm2 uninstall pm2-server-monit Monitor Server Resources from PM2 Dashboard Now you can monitor your server resources from the web dashboard as shown in the following image. If PM2 is linked to, pm2-server-monit should automatically appear in the list of monitored processes.
#Monit nodejs install#
To install it, run the following command: # pm2 install pm2-server-monit
#Monit nodejs free#
Pm2-server-monit is a PM2 module to automatically monitor key aspects of your server such as CPU average usage, free and used drive space, free and used memory space, all processes running, TTY/SSH opened, the total number of open files, as well as network speed (input and output). Monitoring Your Server Resources Using pm2-server-monit
Unlink Nodejs Server from PM2 Web DashboardĪfter running the above command, you can delete the server from the dashboard. To unlink a server from the monitoring dashboard, run the following command on the server to unlink: # pm2 unlink Monitor Nodejs Applications from PM2.io Dashboard If you are using version control, it also shows the branch and last merge details. It also shows the version of Nodejs and PM2 currently installed.įor each process, you will see the percentage of CPU and the amount of memory it is consuming, and much more. For each server connected, the dashboard shows you server hardware components such as the amount of RAM and CPU type. Now on the PM2.io main interface, you should have one server connected, showing a list of all your Nodejs processes in expanded mode. Then run the above command on the Nodejs application server.
Next, link PM2 to PM2.io and copy the command provided as highlighted in the following interface. In this example, we have called our bucket TECMINT-APIs. PM2 SignupĪfter a successful login, create a bucket to group your Nodejs servers/applications. To start testing PM2 plus, go to, then sign up as shown in the following screenshot. The free plan allows you to connect up to 4 servers/applications. It features issues and exception tracking, deployment reporting, real-time logs, email and slack notification, custom metrics monitoring, and custom actions center. It provides features for both hardening your current PM2 and monitoring applications in production across servers.
#Monit nodejs plus#
PM2 Plus ( PM2 Web Based Dashboard) is an advanced and real-time monitoring and diagnostics tool. Monitoring Nodejs Application Using PM2 Web-Based Dashboard To monitor and diagnose cross-server applications, use the PM2 web-based dashboard. The terminal-based monitoring only works well for applications running on a single server. To view logs of an app, first select it (use up/down arrows) from the process list. Once it running, use the left/right arrows to switchboards or sections. You can launch the dashboard by running the following command. PM2 provides a terminal-based dashboard that helps you monitor the resource (memory and CPU) usage of your application.
