2.8.2. Upgrading a PMNS to Include Metrics from a New PMDA

When invoked with a -N command-line option, the PMDA Install script may be used to update the PMNS without installing the PMDA. This functionality is rarely, if ever, used in modern versions of PCP, but allows one to populate the local PMNS with the names of the performance metrics from a PMDA installed on a remote host. The -N option can also install pmchart views useful on a monitoring system, although this also is rarely used now with each platforms package management tools handling this task.
