* - Read and process /sys/class/net/XXXX/duplex and /sys/class/net/XXXX/operstate - Create custom variables duplex_state and operstate under the bandwidth chart - Map states to numeric values Duplex state (variable duplex_state) 0 = unknown 1 = half duplex 2 = full duplex Operstate status map (variable operstate) 0 = unknown 1 = notpresent 2 = down 3 = lowerlayerdown 4 = testing 5 = dormant 6 = up * - Fix array size element count! - Return int value - Fix casting warning * - Variable rename duplex_state to duplex * - Move the variable definition out of the loop
2020-01-02[Fix] remove pthread_setname_np segfault on musl (#7664)Adrien Mahieux

Both are based on pthread, but for uv we need to call it with the uv_thread_t pointer, instead of being the thread that calls the function for itself. * [exporting] Set libuv threadname to "EXPORTING-index" * [database/engine] Set libuv thread name to "DBENGINE" * [daemon/command] Set libuv thread name to "DAEMON-COMMAND" * [collectors/proc] Set pthread name to "PLUGIN[cpuidle]" * Use new 'thread_set_name_np' name

2019-07-09Add ZRAM collector module to the proc pluginVilkov Adel
The module gets the ZRAM device list by reading /proc/devices, obtaining an device ID from it, then enumerating the devices in /dev filtering them by corresponding major device number it got from previous step. It takes the data from /sys/block/{name}/mm_stat.
