NAME

       labels.conf - Performance Co-Pilot labels configuration

SYNOPSIS

       /etc/pcp/labels.conf

DESCRIPTION

       Several Performance Co-Pilot (PCP) tools and utilities support
       the use of metric labels.  This functionality applied a
       hierarchical set of labels to each instance of every metric, as
       described in pmLookupLabels(3).

       The pmcd(1) and pmproxy(1) daemons are particularly important to
       the labels system, respectively providing the labels in real-time
       and then discovering recorded (archive) labels and indexing these
       for pmseries(1) queries using a redis-server(1).

       The /etc/pcp/labels.conf file is a single point of configuration
       for behaviour affecting all labels exported by pmcd or through
       tools using PMAPI local context services.  It uses the common
       ``ini'' file format and any variable it specifies that is not in
       an explicit square-bracket enclosed section is considered a
       [global] variable.

       The available configuration variables are as follows :

       machineid_hash=none|sha256
            When specified in the [global] section, controls the manner
            in which the local machine-id(5) is exported as a label.
            The default setting (none) exports a "machineid" context
            label with value reflecting the contents of the
            /etc/machine-id file, on any platforms that provide this
            file.  The alternative (sha256) exports a "machineid_sha256"
            label, instead, and the value is the SHA256 (one-way) hash
            of the file.
