NAME
pmieconf - display and set configurable pmie rule variables
SYNOPSIS
pmieconf [-cFv] [-f file] [-r rulepath] [command [args...]]
DESCRIPTION
pmieconf is a utility for viewing and configuring variables from generalized pmie(1)
rules. The set of generalized rules is read in from rulepath, and the output file
produced by pmieconf is a valid input file for pmie.
A brief description of the pmieconf command line options follows:
-c When run from automated pmie setup processes, this option is used to add a
specific message and timestamp indicating that this is the case. It is not
appropriate when using the tool interactively.
-f file Any rule modifications resulting from pmieconf manipulation of variable values
will be written to file. The default value of file is dependent on the user ID -
for the root user, the file $PCP_VAR_DIR/config/pmieconf/config.pmie is used, for
other users the default is $HOME/.pcp/pmie/config.pmie.
-F Forces the pmieconf output file to be created (or updated), after which pmieconf
immediately exits.
-r rulepath
Allows the source of generalized pmie rules to be changed - rulepath is a colon-
delimited list of pmieconf(5) rule files and/or subdirectories. The default value
for rulepath is $PCP_VAR_DIR/config/pmieconf. Use of this option overrides the
PMIECONF_PATH environment variable which has a similar function.
-v Verbose mode. Additional information associated with each rule and its associated
variables will be displayed. This is the complete list of variables which affects
any given rule (by default, global variables are not displayed with the rule).
The pmieconf commands allow information related to the various rules and configurable
variables to be displayed or modified. If no pmieconf commands are presented on the
command line, pmieconf prompts for commands interactively.
The pmieconf command language is described here:
help [ { . | all | global | <rule> | <group> } [<variable>] ]
Without arguments, the help command displays the syntax for all of the available
pmieconf commands. With one argument, a description of one or more of the
generalized rules is displayed. With two arguments, a description of a specific
variable relating to one or more of the generalized rules is displayed.
rules [ enabled | disabled ]
Display the name and short summary for all of the generalized rules found on
rulepath. Each of the rule names can be used in place of the keyword <rule> in
this command syntax description. The enabled and disabled options can be used to
filter the set of rules displayed to just those which are enabled or disabled
respectfully.
groups Display the name of all of the rule groups that were found on rulepath. Each of
the group names can be used in place of the keyword <group> in this command syntax
description, which applies the command to all rules within the rule group.
status Display status information relating to the current pmieconf session, including a
list of running pmie processes which are currently using file.
enable { . | all | <rule> | <group> }
Enables the specified rule or group of rules. An enabled rule is one which will
be included in the pmie configuration file generated by pmieconf. Any enabled
"actions" will be appended to the rule's "predicate", in a manner conforming to
the pmie syntax ("actions" can be viewed using the list global command, described
below).
disable { . | all | <rule> | <group> }
Disables the specified rule or group of rules. If the rule was previously
enabled, it will be removed from the pmie configuration file generated by
pmieconf, and hence no longer evaluated when pmie is restarted (using pmieconf
does not affect any existing pmie processes using file).
list { . | all | global | <rule> | <group> } [<variable>]
Display the values for a specific rule variable; or for all variables of a rule, a
rule group, all rules, or the global variables.
modify { . | all | global | <rule> | <group> } <variable> <value>
Enable, disable, or otherwise change the value for one or more rule variables.
This value must be consistent with the type of the variable, which can be inferred
from the format of the printed value - e.g. strings will be enclosed in double-
quotes, percentages have the ``%'' symbol appended, etc. Note that certain rule
variables cannot be modified through pmieconf - "predicate" and "help", for
example.
undo { . | all | global | <rule> | <group> } [<variable>]
Applicable only to a variable whose value has been modified - this command simply
reverts to the default value for the given variable.
quit Save any changes made to file and then exit pmieconf.
abort Exit pmieconf immediately without saving any changes to file.
Each of the commands above can be shortened by simply using the first character of the
command name, and also ``?'' for help.
Use of the all keyword causes the command to be applied to all of the rules. The global
keyword refers to those variables which are applied to every rule. Such variables can be
changed either globally or locally, for example:
pmieconf> modify global delta "5 minutes"
pmieconf> modify memory delta "1 minute"
causes all rules to now be evaluated once every five minutes, except for rules in the
"memory" group which are to be evaluated once per minute.
The ``.'' character is special to pmieconf - it refers to the last successfully used value
of all, global, <rule> or <group>.
EXAMPLES
Specify that all of the rules in the "memory" group should be evaluated:
pmieconf> modify memory enabled yes
Change your mind, and revert to using only the "memory" rules which were enabled by
default:
pmieconf> undo memory enabled
Specify that notification of rules which evaluate to true should be sent to syslogd(1):
pmieconf> modify global syslog_action yes
Specify that rules in the "per_cpu" group should use a different holdoff value to other
rules:
pmieconf> help global holdoff
rule: global [generic parameters applied to all rules]
var: holdoff
help: Once the predicate is true and the action is executed,
this variable allows suppression of further action
execution until the specified interval has elapsed.
A value of zero enables execution of the action if
the rule predicate is true at the next sample. Default
units are seconds and common units are "second", "sec",
"minute", "min" and "hour".
pmieconf> modify per_cpu holdoff "1 hour"
Lower the threshold associated with a particular variable for a specified rule:
pmieconf> l cpu.syscall predicate
rule: cpu.syscall [High aggregate system call rate]
predicate =
some_host (
( kernel.all.syscall $hosts$ )
> $threshold$ count/sec * hinv.ncpu $hosts$
)
pmieconf> m . threshold 7000
pmieconf> l . threshold
rule: cpu.syscall [High aggregate system call rate]
threshold = 7000
ENVIRONMENT
The environment variable PMIECONF_PATH has a similar function to the -r option described
above, and if set will be used provided no -r option is presented.

PCP ENVIRONMENT
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).
