Specifications
- Standard agent: yes
- Monitoring Parameters: 11
- Data Source: /proc, process information pseudo-filesystem
- API: Sys::Statistics::Linux
- Programming Language: Perl 5
Functions
Records system performance metrics from a Linux 32 or 64bit kernel. The agent requires a minimum version of Linux kernel 2.6 version. The recorder uses Sys::Statistics::Linux, a Perl based module which handles data collection from proc interface. The recorder outputs collected data as sdrd, sdr raw data format.
Parameters
cpurec records per CPU performance metrics, like user, system, idle utilization and several other metrics.
