# 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 `pid table size` defines the maximum number of PIDs stored inside the application hash table.
#
# The `ebpf type format` option accepts the following values :
#  `auto`  : The eBPF collector will investigate hardware and select between the two next options.
#  `legacy`: The eBPF collector will load the legacy code. Note: This has a bigger overload.
#  `co-re` : The eBPF collector will use latest tracing method. Note: This is not available on all platforms.
#
# The `ebpf co-re tracing` option accepts the following values: 
#   `trampoline`: This is the default mode used by the eBPF collector, due the small overhead added to host.
#   `probe`     : This is the same as legacy code.
#
# The `collect pid` option defines the PID stored inside hash tables and accepts the following options:
#   `real parent`: Only stores real parent inside PID
#   `parent`     : Only stores parent PID.
#   `all`        : Stores all PIDs used by software. This is the most expensive option.
#
# The `maps per core` defines if hash tables will be per core or not. This option is ignored on kernels older than 4.6.
#
# The `lifetime` defines the time length a thread will run when it is enabled by a function.
#
# Uncomment lines to define specific options for thread.
