Specifications
- Standard agent: yes
- Monitoring Parameters: 20
- 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
nicrec records per NIC statistics, receiving and transmitting metrics: the no. of KBytes received/sec, the no. of packets received/sec, the no. of KBytes transmitted/sec, the no. of packets transmitted/sec and many other metrics.
