# # Global options # # The `ebpf load mode` option accepts the following values : # `entry` : The eBPF collector only monitors calls for the functions, and does not show charts related to errors. # `return : In the `return` mode, the eBPF collector monitors the same kernel functions as `entry`, but also creates # new charts for the return of these functions, such as errors. # # The eBPF collector also creates charts for each running application through an integration with the `apps.plugin` # or `cgroups.plugin`. # If you want to disable the integration with `apps.plugin` or `cgroups.plugin` along with the above charts, change the setting # `apps` and `cgroups` to 'no'. # # The `update every` option defines the number of seconds used to read data from kernel and send to netdata # # The `pid table size` defines the maximum number of PIDs stored in the application hash tables. # [global] ebpf load mode = entry apps = yes cgroups = no update every = 5 pid table size = 32768 btf path = /sys/kernel/btf/ # # eBPF Programs # # The eBPF collector has the following eBPF programs: # # `cachestat` : Make charts for kernel functions related to page cache. # `dcstat` : Make charts for kernel functions related to directory cache. # `disk` : Monitor I/O latencies for disks # `fd` : This eBPF program creates charts that show information about file manipulation. # `filesystem`: Monitor calls for functions used to manipulate specific filesystems # `hardirq` : Monitor latency of serving hardware interrupt requests (hard IRQs). # `mdflush` : Monitors flush counts for multi-devices. # `mount` : Monitor calls for syscalls mount and umount # `oomkill` : This eBPF program creates a chart that shows which process got OOM killed and when. # `process` : This eBPF program creates charts that show information about process life. # `shm` : Monitor calls for syscalls shmget, shmat, shmdt and shmctl. # `socket` : This eBPF program creates charts with information about `TCP` and `UDP` functions, including the # bandwidth consumed by each. # `softirq` : Monitor latency of serving software interrupt requests (soft IRQs). # `sync` : Monitor calls for syscall sync(2). # `swap` : Monitor calls for internal swap functions. # `vfs` : This eBPF program creates charts that show information about process VFS IO, VFS file manipulation and # files removed. # # When plugin detects that system has support to BTF, it enables integration with apps.plugin. # [ebpf programs] cachestat = no dcstat = no disk = no fd = yes filesystem = no hardirq = yes mdflush = no mount = yes oomkill = yes process = yes shm = no socket = yes softirq = yes sync = yes swap = no vfs = yes network connections = no
