2.8.3. Removing a PMDA

The simplest way to stop a PMDA from running, apart from killing the process, is to remove the entry from ${PCP_PMCDCONF_PATH} and signal PMCD (with SIGHUP) to reread its configuration file. To completely remove a PMDA requires the reverse process of the installation, including an update of the Performance Metrics Name Space (PMNS).
This typically involves a Remove script in the PMDA directory that uses the same common procedures as the Install script described Section 2.8.1, “Installing a PMDA”.
The ${PCP_PMDAS_DIR}/*/Remove files provide a wealth of examples that may be used to construct a new PMDA Remove script.
