librtinfo

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

Monitoring

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

Dependencies

There is no dependencies except default linux headers

How to use it

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

Data representation

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 representation

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)

Arguments

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.

Compilation

Just compile your code using -lrtinfo
