openMetrics PMDA (OpenMetrics PMDA)
METRIC NAMING
All metrics from a file named JOB.* will be exported as PCP
metrics with the openmetrics.JOB metric name prefix. Therefore,
the JOB name must be a valid non-leaf name for PCP PMNS metric
names. If the JOB name has multiple dot-separated components,
the resulting PMNS names will include those components and care
is needed to ensure there are no overlapping definitions, e.g.
metrics returned by JOB.response may overlap or conflict with
metrics returned by JOB.response.time.
Config file entries (URLs or scripts) found in subdirectories of
the config directory will also result in hierarchical metric
names. For example, a config file named
$PCP_PMDAS_DIR/openmetrics/config.d/mysource/latency/get.url will
result in metrics being created (by fetching that source URL)
below openmetrics.mysource.latency.get in the PCP namespace.
Scripts found in subdirectories of the config directory similarly
result in hierarchical PCP metric names.
