демон сборщика показателей производительности (performance metrics collector daemon)
Конфигурация (Configuration)
On startup pmcd looks for a configuration file named
$PCP_PMCDCONF_PATH. This file specifies which agents cover which
performance metrics domains and how pmcd should make contact with
the agents. An optional section specifying access controls may
follow the agent configuration data.
Warning: pmcd is usually started as part of the boot sequence and
runs initially as root. The configuration file may contain shell
commands to create agents, which will be executed by root. To
prevent security breaches the configuration file should be
writable only by root. The use of absolute path names is also
recommended.
The case of the reserved words in the configuration file is
unimportant, but elsewhere, the case is preserved.
Blank lines and comments are permitted (even encouraged) in the
configuration file. A comment begins with a ``#'' character and
finishes at the end of the line. A line may be continued by
ensuring that the last character on the line is a ``\''
(backslash). A comment on a continued line ends at the end of
the continued line. Spaces may be included in lexical elements
by enclosing the entire element in double quotes. A double quote
preceded by a backslash is always a literal double quote. A
``#'' in double quotes or preceded by a backslash is treated
literally rather than as a comment delimiter. Lexical elements
and separators are described further in the following sections.
