watched.agent

Overview

Watched aim to become a performance analysis and a monitoring tool. This is the plugin-based agent written in C++. It provide a REST api to the data that the backend consume. Plugins can be written in c++ or in lua

Dependencies

This project is based on the following projects :

• jsoncpp
• SimpleWebServer (itself based on Boost::asio)
• Selene to provide lua integration
• Lua Version 5.2 or 5.3
• Boost version >= 1.54
• C++11 compatible compiler (gcc >=4.9, clang >=3.3)
• Linux

Other componants

• watched.back Centralize the agents metric and monitor them.
• watched.front Provide the interface to the centralized data

build instruction

mkdir build
cd build
cmake ..
make
sudo make install

Current features

• Very lightweight
• Forward the collected data to the backend over a REST service
• C++ and lua plugins framework for services management and system metrics
• Detect network services and monitor them
• Service performance data
• Service classification
• Service log monitoring
• Can be secured using SSL (tls1.2)
• Offer a web micro frontend (might be used to monitor a single host)
• Plugins for :
  • systemd services detection
  • Service CPU, memory and IO metrics
  • System CPU, memory, uptime, disk, IO, and network metrics

Planned

• Plugins for :
  • systemd log monitoring
  • docker services detection, enhencement
  • libvirt
  • pacemaker
  • and more
• More than one listen adress

TODO

• Remove service missing for more than 15mn
• LogSource support (services.h:76)
• Add support for controlGroup (services.h:100)
• Add the ability to create service in LuaDetector (luacollectors.cpp:226)
• Fix the lua collector memory growth (have c++ collector in the mean time)
• SubProcess cleanup (services.cpp:668)
• Improve service matching (services.cpp:770)
• Improve service updating (services.cpp:853)
• Add support for service dependencies (servicesManager.cpp:628)
• add support for sigusr1 which reload configs et reopen log
• More usage of pidRessource in plugins and lua too
