pmloadderivedconfig

PMLOADDERIVEDCONFIG(3)					     Library Functions Manual					    PMLOADDERIVEDCONFIG(3)

NAME

       pmLoadDerivedConfig - load derived metric definitions from a file

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmLoadDerivedConfig(char *fname);

       cc ... -lpcp

DESCRIPTION

       Each  line of the file fname is either a comment line (with a ``#'' in the first position of the line) or the declaration of a derived per-
       formance metric, specified as:

       * the name of the derived metric, using the same ``dot notation'' syntax that is used for PCP  performance  metrics,  see  PCPIntro(1)  and
	 pmns(5).

       * an equals sign (``='')

       * a valid expression for a derived metric, as described in pmRegisterDerived(3).

       White space is ignored in the lines.

       For each line containing a derived metric definition, pmRegisterDerived(3) is called to register the new derived metric.

       The  result  from pmLoadDerivedConfig will be the number of derived metrics loaded from fname else a value less than zero in the case of an
       error.

EXAMPLE

       # sample derived metric definitions
       bad_in_pkts = network.interface.in.errors + network.interface.in.drops
       # note the following would need to be on a single line ...
       disk.dev.read_pct = 100 * delta(disk.dev.read) /
		   (delta(disk.dev.read) + delta(disk.dev.write))

SEE ALSO

       PCPIntro(1), PMAPI(3) and pmRegisterDerived(3).
