A recent survey from AppDynamics and Dimensional Research found that: 1) 88% of respondents indicated putting a monetary value on the cost of poor user experience was important, but only 38% quantified that themselves despite having the analytical tools to manage user experience
In this article, we will explain how we are using Rocket.chat as our internal chat and how we deploy this tool. You can use IRC, Jabber (XMPP) or any other "modern" chat system: Slack, Rocket.Chat, etc. After using XMPP for a couple of months, we decided to move to Rocket.Chat.
At Bleemeo, as many geeks, we use a couple of tools on a day to day basis. Most of those tools are small Open Source web applications and, to be trendy, we deploy those tools with Docker. In the past, we used to create a virtual machine per service, deploy the tool and configure web server on each machine. Moreover if you are using https, you need to deploy certificates and private keys on each server.

SSLping was born as a side project. It’s useful to people, which is cool, but today it was also helpful to me! I use it to monitor my HTTPS websites. This morning, my own SSLping project sent me an email about how my website https://hire.chris-hartwig.com is about to expire (in 10 days): it’s using Letsencrypt, and it’s been 80 days since I installed the cert.
TL;DR you’re never done with Let’s encrypt: once your servers are secure, you must ensure they stay that way. Let’s encrypt is a no brainer: this initiative benefits us all, with free domain-validated certificates. It’s easy to setup and free. There’s probably automatic installation for your web server of choice, the community behind it can help, and tutorials are everywhere. Then you head to https://
In this post, we will set up a simple SSL certificate expiry monitoring, using cron, ssl-cert-check script and a fail-safe provided by an external service, healthchecks.io.
It was in your TodoList: install the SSL certificate. So you’ve setup your SSL certificate on the web server. It’s quite trendy to use SSL. Google will give you a modest ranking bump, some users will feel safer, all is good. You have even tested your configuration with Qualys, got you an A+. Good job: most got a C, even banks. Now what? What will happen when your cert is about to expire? Your CA will send an email to renew your cert. But maybe someone in the accounting dept will get that email.
When your software goes down, there are two audiences that need to know about it. One: the people who are going to get frustrated and blame you for the inconvenience. Two: the people who can fix the problem. The first audience doesn’t need to know the details of the problem – they just need to know that you’re on top of fixing it, and how long they can expect to wait before full functionality is restored (insofar as you can make a realistic estimate about that).
If you care about the uptime status of your website or SaaS application, there are two really great pieces of content shared last month that you should look into. One is an article on continuous testing from Parasoft Corporation, featured on DZone. The other is a recorded presentation on Application Performance Monitoring (APM) by Expected Behavior, from the Full Stack Toronto conference.
