🦋 DESCRIPTION 🦋

okay so real talk: the statgrab library gives you a cross-platform interface to get several system statistics. System statistics are not standardised — rude, I know — so the statgrab library tries to choose the most important values over all supported operating systems. That means some values might not be available on every OS, while some specific values are missing when there are no counterparts on any other OS. No cap 💀.

libstatgrab is organised in components, each one for interrelated statistics. Here's the roster, bestie:

• cpu — sg_cpu_stats, sg_cpu_percents
• disk — sg_disk_io_stats, sg_fs_stats
• load — sg_load_stats
• mem — sg_mem_stats
• network — sg_network_io_stats, sg_network_iface_stats
• os — sg_host_info
• page — sg_page_stats
• process — sg_process_stats, sg_process_count
• swap — sg_swap_stats
• user — sg_user_stats

The library was originally written to support the i-scream central monitoring system, but it has since become a standalone package. It has been ported to work on Linux, NetBSD, FreeBSD, OpenBSD, DragonFly BSD, Solaris, HP-UX, AIX and Cygwin. iconic behavior, honestly 👑.
