       pmlogconf - create/edit a pmlogger configuration file


       $PCP_BINADM_DIR/pmlogconf [-cqrv] [-d groupsdir] [-h hostname] configfile


       pmlogconf  may  be  used  to  create  and  modify a generic configuration file for the PCP
       archive logger, pmlogger(1).

       If configfile does not exist, pmlogconf will create a generic configuration  file  with  a
       default set of enabled metrics and logging intervals.

       Once  created,  configfile  may  be  used  with  the  -c  option  to pmlogger(1) to select
       performance metrics and specify logging intervals for a PCP archive.

       If configfile does exist, pmlogconf will prompt for input  from  the  user  to  enable  or
       disable groups of related performance metrics and to control the logging interval for each
       enabled group.

       Group selection requires a simple y (yes) or n  (no)  response  to  the  prompt  Log  this

       Other  responses  at  this  point  may  be  used to select additional control functions as

       m         Report the names of the metrics in the current group.

       q         Finish with group selection (quit) and make no further changes to this group  or
                 any subsequent group.

       /pattern  Make  no  change  to this group but search for a group containing pattern in the
                 description of the group or the names of the associated metrics.

       A logging interval is specified by responding to the Logging interval?   prompt  with  the
       keywords once or default or a valid pmlogger(1) interval specification of the form ``every
       N timeunits'' or simply ``N timeunits '' (the every is optional) where N  is  an  unsigned
       integer  and timeunits is one of the keywords msec, millisecond, sec, second, min, minute,
       hour or the plural form of one of the keywords.

       When run from automated logging setup processes, the -c option is used to  add  a  message
       and timestamp indicating this fact.  This option is not appropriate for interactive use of
       the tool.

       The -q option suppresses the logging interval dialog and preserves  the  current  interval
       from configfile.

       More verbose output may be enabled with the -v option.


       When an initial configfile is created, the default specifications come from a set of group
       files below the  groupsdir  specified  with  the  -d  option  (the  default  groupsdir  is
       $PCP_VAR_DIR/config/pmlogconf  which  is most commonly correct, so the -d option is rarely
       used in practice).

       The directory structure below groupsdir is arbitrary as all regular files will be found by
       recursive descent and considered, so add-on products and PMDA developers can easily extend
       the available defaults to pmlogconf by adding new directories  and/or  group  files  below

       These group files are processed in the following ways:

       ·  When a new configfile is created, all group files are processed.

       ·  Whenever pmlogconf is run with an existing configfile, groupsdir is traversed to see if
          any new groups have been defined and should be considered for inclusion in configfile.

       ·  When pmlogconf processes a group in configfile that is enabled,  the  list  of  metrics
          associated  with the group is taken from the group file (and replaces any previous list
          of metrics associated with this group in configfile).

       ·  When the -r (reprobe) command line option is specified, every  group  (not  just  newly
          discovered  ones)  is  reprocessed  to  see if it should be considered for inclusion in

       Each group file is structured as follows:

       ·  The first line must contain #pmlogconf-setup 2.0

       ·  Other lines beginning with # are treated as comments.

       ·  Blank lines are ignored.

       ·  One or more lines starting with the keyword  ident  are  used  to  provide  the  human-
          readable description of the group.

       ·  Non-blank  lines  beginning  with white space define metrics to be associated with this
          group, one per line.  Each metric specification follows the  rules  for  a  pmlogger(1)
          configuration,  namely  either  the  name  of a non-leaf node in the PMNS (implying all
          descendent names in the PMNS), or the name of  a  leaf  node  in  the  PMNS  optionally
          followed by one or more instance names enclosed by ``['' and ``]''.

       ·  A control line starting with one of the keywords probe or force must be present.

       ·  An optional logging interval control line begins with the keyword delta followed by one
          of the pmlogger(1) interval specification described above.

       ·  probe control lines have the format:
                                  probe metric [condition [state_rule] ]
          where metric is the name of a PCP metric (must be a  leaf  node  in  the  PMNS  and  no
          instance  specification  is  allowed)  and the optional condition is the keyword exists
          (true if metric exists, i.e. is defined in the PMNS) or the  keyword  values  (true  if
          metric  exists  in the PMNS and has one or more current values) or an expression of the
                                                  op val
          where op is one of the awk(1) operators (==, !=, >, >=, <, <=,  ~  (regular  expression
          match) or !~ (negated regular expression match)) and val is a value (arbitrary sequence
          of characters, excluding a space) and the condition is true if there is  some  instance
          of metric that makes the expression true.

          If the condition is missing, the default is exists.

          When an explicit condition is provided, there may also be an optional state_rule of the
                                        ? true_state : false_state
          where true_state (applies if condition is true) and false_state (applies  if  condition
          is  false)  are  both taken from the keywords include (include and enable the group and
          the associated metrics in configfile), available (include  and  disable  the  group  in
          configfile  -  a  user action of y as described above is needed to enable the group and
          add the associated metrics into configfile) or exclude (the group is not considered for
          inclusion in configfile).

          The default state_rule is
                                           ? available : exclude

       ·  force  control lines begin with the keyword force followed by one of the states defined
          above, so one of the actions include, exclude or available is  applied  unconditionally
          to the group.

       Probing  is only done when a new group is being added to configfile or when the -r command
       line option is specified.  The evaluation of the probing conditions is done by  contacting
       pmcd(1) on hostname (defaults to local:).


       The following group file demonstrates all of the supported syntactic elements.

       #pmlogconf-setup 2.0
       ident   Example group file
       ident   ... more description
       delta   1 minute
       probe values ? include : exclude
        # non-leaf in the PMNS
               sample.colour [ red green ]


       The current version of pmlogconf (2.0) supports a slightly different format for configfile
       compared to earlier versions.  If an old version configfile is presented to  pmlogconf  it
       will be converted to the new format.


       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).
