           status.
    

##  FILES  top

    
    
           For each of the _input_ and _output_ archives, several physical files
           are used.
    
           _archive_**.meta**
                metadata (metric descriptions, instance domains, etc.) for
                the archive
    
           _archive_**.0**
                initial volume of metrics values (subsequent volumes have
                suffixes **1** , **2** , ...) - for _input_ these files may have been
                previously compressed with **bzip2**(1) or **gzip**(1) and thus may
                have an additional **.bz2** or **.gz** suffix.
    
           _archive_**.index**
                temporal index to support rapid random access to the other
                files in the archive.
    

##  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).
