Specifications
- Standard agent: yes
- Monitoring Parameters: 43
- 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
sysrec records system utilization, saturation and errors from CPU, memory, disks and network cards, overall values across all devices found. It is very important to start your analysis using the results of this recorder, since this will present the overall situation across all devices, cumulative.
