Blackfire.io vs SeaLion: What are the differences?
Blackfire.io: Blackfire Profiler automatically instruments your code to gather data about consumed server resources like memory, CPU time, and I/O. Blackfire achieves a new level of accuracy by aggregating several profile samples and getting rid of non relevant data. Get even deeper and review the interactions with your entire stack (SQL database engines, cache servers, ...); SeaLion: Quickly diagnose problems with your Linux servers. SeaLion is a cloud based system monitoring tool for Linux servers. Getting started is as easy as executing a command. It installs an agent at /usr/local/sealion-agent and runs as an unprivileged user (sealion). This agent will collect data at regular intervals across servers and this data will be available on your workspace. The latest version is shipped with 5 default services namely Apache, NGINX, MongoDB, MySQL, Redis.
Blackfire.io and SeaLion belong to "Performance Monitoring" category of the tech stack.
Some of the features offered by Blackfire.io are:
- Profile a page at a mouse click thanks to the Blackfire web browser extension
- Browse through the function calls and identify performance bottlenecks thanks to the Blackfire intuitive UI
