This is a small library (less than 1000 lines of C code) able to build easy-to-use data structures containing system information

This library can monitor (only Linux is really supported):

• Basic overall cpu usage
• Basic overall memory (ram and swap) usage
• Battery status if any
• Disks usage (bytes read/written, read/write rate)
• System load average
• Network usage (interface, state, speed, current rate, address, ...)
• HDD and CPU tempeature
• Current system time and uptime

There is no dependencies except default linux headers

First of all, please check example/librtinfo-test.c which shows you how to use library internals.

All data structures are formatted like: rtinfo_{type}_t (eg: rtinfo_memory_t) Here is a basic list of available structures:

- rtinfo_cpu_t
    rtinfo_cpu_dev_t
    rtinfo_cpu_time_t
- rtinfo_disk_t
    rtinfo_disk_dev_t
    rtinfo_disk_sectors_t
- rtinfo_memory_t
- rtinfo_loadagv_t
- rtinfo_battery_t
    info_battery_status_t
- rtinfo_network_t
    rtinfo_network_if_t
    rtinfo_network_byte_t
- rtinfo_uptime_t
- rtinfo_temp_cpu_t
- rtinfo_temp_hdd_t

Functions to manage structures are formatted like: rtinfo_{action}_{type} (eg: rtinfo_get_memory)

Some functions (like cpu, network and disks) require initialization: rtinfo_init_{type} (eg: rtinfo_init_cpu)

Init functions need an integer as argument and return a pointer to a valid structure. Getter functions need an pointer to the data structure to use. mk functions need some different arguments, please read rtinfo.h for more information.

Just compile your code using -lrtinfo
