Profiling and tracing from ptrace to SystemTap
Modern OS and CPUs come with a variaty of APIs for monitoring. Ptrace based commands like strace are easy to use but slow. Perf allows lightweight profiling. SystemTap is a powerfil toolkit plus DSL to instrument probe points inside the Kernel as well as static SystemTap/DTrace markers in libs and languages like Java, PHP, and Python. In my talk I'll show and compare various low and high level tools as well as visualization tools, e.g. how to create flame graph.

Performance Co-Pilot and Ruby
Performance Co-Pilot (PCP) is an open source framework and toolkit for monitoring and analyzing live and historical system performance. It provides high-resolution live monitoring from local or remote hosts (with optional auto-discovery) and instrumented software. PCP can be integrated with monitoring solutions like Graphite (Carbon/Whisper), InfluxDB, Zabbix or Nagios, or configured to store historical data into archive files which is a unique feature we want to take advantage from. The talk covers PCP installation, basic operating system monitoring and shows how to read internal metrics from a Ruby application via Statsd or Prometheus APIs.
