# | arg: -f, --footprint - Memory footprint of the service (low/medium/high).
# low - Less than 20Mb of ram by pool.
# medium - Between 20Mb and 40Mb of ram by pool.
# high - More than 40Mb of ram by pool.
# Or specify exactly the footprint, the load of the service as Mb by pool instead of having a standard value.
# To have this value, use the following command and stress the service.
# watch -n0.5 ps -o user,cmd,%cpu,rss -u APP
#
# | arg: -u, --usage - Expected usage of the service (low/medium/high).
# low - Personal usage, behind the sso.
# medium - Low usage, few people or/and publicly accessible.
# high - High usage, frequently visited website.
#
# | arg: -p, --print - Print the result
#
#
#
# The footprint of the service will be used to defined the maximum footprint we can allow, which is half the maximum RAM.
# So it will be used to defined 'pm.max_children'
# A lower value for the footprint will allow more children for 'pm.max_children'. And so for
# 'pm.start_servers', 'pm.min_spare_servers' and 'pm.max_spare_servers' which are defined from the
# value of 'pm.max_children'
# NOTE: 'pm.max_children' can't exceed 4 times the number of processor's cores.
#
# The usage value will defined the way php will handle the children for the pool.
# A value set as 'low' will set the process manager to 'ondemand'. Children will start only if the
# service is used, otherwise no child will stay alive. This config gives the lower footprint when the
# service is idle. But will use more proc since it has to start a child as soon it's used.
# Set as 'medium', the process manager will be at dynamic. If the service is idle, a number of children
# equal to pm.min_spare_servers will stay alive. So the service can be quick to answer to any request.
# The number of children can grow if needed. The footprint can stay low if the service is idle, but
# not null. The impact on the proc is a little bit less than 'ondemand' as there's always a few
# children already available.
# Set as 'high', the process manager will be set at 'static'. There will be always as many children as
# 'pm.max_children', the footprint is important (but will be set as maximum a quarter of the maximum
# RAM) but the impact on the proc is lower. The service will be quick to answer as there's always many
