Конфигурационный файл (Config file)
By default htop reads its configuration from the XDG-compliant
path ~/.config/htop/htoprc. The configuration file is
overwritten by htop's in-program Setup configuration, so it
should not be hand-edited. If no user configuration exists htop
tries to read the system-wide configuration from
${prefix}/etc/htoprc and as a last resort, falls back to its hard
coded defaults.
You may override the location of the configuration file using the
$HTOPRC environment variable (so you can have multiple
configurations for different machines that share the same home
directory, for example).
The pcp-htop utility makes use of htoprc in exactly the same way.
In addition, it supports additional configuration files allowing
new meters and columns to be added to the display via the usual
Setup function, which will display additional Available Meters
and Available Column entries for each runtime configured meter or
column.
These pcp-htop configuration files are read once at startup. The
format of these files is described in detail in the pcp-htop(5)
manual page.
This functionality makes available many thousands of Performance
Co-Pilot metrics for display by pcp-htop, as well as the ability
to display custom metrics added at individual sites.
Applications and services instrumented using the OpenMetrics
format https://openmetrics.io can also be displayed by pcp-htop
if the pmdaopenmetrics(1) component is configured.
