TIMESERIES SOURCES
A source is a unique identifier (represented externally as a
40-byte hexadecimal SHA-1 hash) that represents both the live
host and/or archives from which each timeseries originated. The
context for a source identifier (obtained with -s) can be
reported with:
-S, --sources
Print names for timeseries sources. These names are either
hostnames or fully qualified archive paths.
It is important to note that live and archived sources can and
will generate the same SHA-1 source identifier hash, provided
that the context labels remain the same for that host (labels are
stored in PCP archives and can also be fetched live from
pmcd(1)).
