##  EXIT STATUS  top

    
    
           **pmloglabel** exits with status 0 if the archive labels are clean.
           If invoked incorrectly, the exit status will be 1.  If corruption
           is detected and still exists at the end, the exit status will be
           2.  If requested to write out the archive labels, and some aspect
           of that write out fails, then the exit status will be 3.
    

##  FILES  top

    
    
           _$PCP_LOG_DIR/pmlogger/ <hostname>_
                Default directory for PCP archives containing performance
                metric values collected from the host _< hostname>_.
    

##  PCP ENVIRONMENT  top

    
    
           Environment variables with the prefix **PCP_** are used to
           parameterize the file and directory names used by PCP.  On each
           installation, the file _/etc/pcp.conf_ contains the local values
           for these variables.  The **$PCP_CONF** variable may be used to
           specify an alternative configuration file, as described in
           [pcp.conf(5)](../man5/pcp.conf.5.html).
