vmcore_event: configuration file for libreport.

NAME

report_event.conf - configuration file for libreport.

DESCRIPTION

This configuration file specifies which programs should be run when the specified event occurs in problem directory lifetime.

It consists of directives and rules.

Directives start with a reserved word. Currently, there is only one directive, "include".

include FILE

This directive causes files which match FILE to be read and parsed as if they are inserted textually where this directive occurs. FILE can use shell pattern metacharacters (*,?,etc) to specify multiple files. Relative paths are interpreted relative to current file.

Rule starts with a line with non-space leading character. All subsequent lines which start with space or tab form one rule. Note that separating newline is retained.

Rules may be commented out with #. One # is sufficient to comment out even a multi-line rule (no need to comment out every line).

Rules specify which programs to run on the problem directory. Each rule may have conditions to be checked before the program is run.

Conditions have form VAR=VAL or VAL~=REGEX, where VAR is either word "EVENT" or a name of problem directory element to be checked (for example, "executable", "package", hostname" etc).

If all conditions match, the remaining part of the rule (the "program" part) is run in the shell. All shell language constructs are valid. All stdout and stderr output is captured and passed to ABRT and possibly to ABRT's frontends and shown to the user.

If the program terminates with nonzero exit code, the event processing is considered unsuccessful and is stopped. Last captured output line, if any, is considered to be the error message indicating the reason of the failure, and may be used by abrt as such.

If the program terminates successfully, next rule is read and processed. This process is repeated until the end of this file.

Event XML configuration

These configuration files provides event meta data.

Each file has XML formatting with the following DTD:

<!ELEMENT event            (name+,description+,requires-items?,exclude-items-by-default?,exclude-items-always?,exclude-binary-items?,include-items-by-default?,minimal-rating?,gui-review-elements?,options?)>

name

User visible name of event

description

User visible description

exclude-items-by-default

Comma separated names of excluded problem elements. User can include any of these elements if he wishes it.

include-items-by-default

Comma separated names of included problem elements. User can exclude any of these elements if he wishes it.

exclude-items-always

Comma separated names of included problem elements. User cannot include any of these elements.

exclude-binary-items

If "yes" then all binary problem elements are excluded. User can include them if he wishes it.

minimal-rating

Minimal backtrace rating required for executing the event. Backtrace rating is a measure of backtrace usability and understandability. With an increasing number of unresolved frames the backtrace rating gets lower values.

gui-review-elements

If "yes", user must explicitly approve that all included problem elements can be published. If "no", the event is executed automatically. If not provided, "yes" is expected.

advanced-options

List of options which are hidden in the default view.

label

Event option label

note-html

Event option HTML formatted description

allow-empty

Determines if user can leave the option empty

default-value

A value which is used by default

option:name

Name of exported environment variable name. libreport tools communicate through Environment Variables.

EXAMPLES

EVENT=post-create analyzer=Python   abrt-action-analyze-python

EVENT=post-create
        getent passwd "`cat uid`" | cut -d: -f1 >username
