SeaLion vs TraceView: What are the differences?
Developers describe SeaLion as "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. On the other hand, TraceView is detailed as "Ridiculously Detailed Application Monitoring". Expose everything, from the webserver to database, cache and API calls. The core technology is based on X-Trace, a distributed tracing framework that’s served as the inspiration for companies like Google and Twitter.
SeaLion and TraceView can be primarily classified as "Performance Monitoring" tools.
Some of the features offered by SeaLion are:
- Raw output. No learning curve
- Quickly identify critical issues
- Historical analysis
On the other hand, TraceView provides the following key features:
- Track every machine involved in a transaction and identify bottlenecks in a single click.
- Isolate interesting calls and drill down to the line of code and machine it ran on.
- Tie together code and infrastructure metrics with database, service, and cache calls, all in the context of a single transaction.
