hooto tracker is a web frontend visualization and analysis tool for APM (application performance management).

Features

• Compatible with Linux systems
• Probe point based on process, no need to modify the analyzed application's code
• Continuous tracking and state saving
• Historical rollup of all data (default setup in 30 days)
• Resource Usage capture and charts (CPU, Memory, Network, IO, ...)
• Dynamic Trace capture and graphs (On-CPU, ...)

Install

install from YUM (CentOS 7.x, RHEL 7.x, ...)

step 1: setup yum repo

wget https://www.hooto.com/repo/el/hooto.repo -O /etc/yum.repos.d/hooto.repo

Project

Hooto Tracker use Project to match and manage the processes that need to be tracked.

You can choose different matching pattens to match one or multiple processes in creating a New Project

• Process ID
• Process Name
• Process Command line content

Tips

• Resource Monitoring (CPU, Memory, IO, Net, ...) is collected in real time, until the process exits
• Dynamic Tracing (CPU FlameGraph) is automatically runs in every 20 minutes, 2 minutes each time

Example of FlameGraph in Dynamic Tracing

Processes (Top N)

Hooto Tracker also create a simple page that list the Top N processes, and you can click on the process to create a New Project with a shortcut way.
