[Puppet Users] Augeas lens for zabbix agent config files?
Hi all,
I''m trying to come up with a lens for the zabbix agent config files. I
find the lens language untransparent at best, so I''m struggeling to
figure out what''s up. The debugging possibilities are extremely
limited. Here''s what I have now:
zabbix.aug:
===(**
An adjusted copy of the postfix_main module
**)
module Zabbix_agent
autoload xfm
(************************************************************************
* USEFUL PRIMITIVES
*************************************************************************)
let eol = Util.eol
let comment = Util.comment
let empty = Util.empty
let eq = del /[ \t]*=/ " ="
let word = /[A-Za-z0-9_.-]+/
let value let chr = /[^# \t\n]/ in
let any = /.*/ in
let line = (chr . any* . chr | chr) in
store line
(************************************************************************
* ENTRIES
*************************************************************************)
let entry = [ key word . eq . (value)? . eol ]
(************************************************************************
* LENS
*************************************************************************)
let lns = (comment|empty|entry) *
let filter = incl "/etc/zabbix/zabbix_agentd.conf"
. incl "/etc/zabbix/zabbix_agent.conf"
. Util.stdexcl
let xfm = transform lns filter
==
a sample snippet from a zabbix agent.conf:
== # head -n25 /etc/zabbix/zabbix_agentd.conf
###########################################################
# PUPPET MANAGED #
# Do not edit this file on a server node unless you #
# are willing to have your changes overwritten by #
# Puppet. If you really want to change the contents #
# repository and check it out on the puppet server. #
###########################################################
# This is config file for zabbix_agentd
# To get more information about ZABBIX, go http://www.zabbix.com
############ GENERAL PARAMETERS #################
# List of comma delimited IP addresses (or hostnames) of ZABBIX servers.
# No spaces allowed. First entry is used for sending active checks.
# Note that hostnames must resolve hostname->IP address and
# IP address->hostname.
Server=backend.yomamma.com
# Server port for sending active checks
#ServerPort=10051
# Unique hostname. Required for active checks.
==
And the augeas output (all empty):
=[/etc/puppet] # augparse /usr/share/augeas/lenses/contrib/zabbix_agent.aug
[/etc/puppet] # augtool -e ls /files/etc/zabbix/zabbix_agentd.conf
=
Any help would be sincerely appreciated :)
cheers,

Hi Walter, [ CCing the augeas-devel list, as that''s the best place for Augeas lens problems and help ] On 22/01/12 20:48, Walter Heck wrote:> Hi all, > > I''m trying to come up with a lens for the zabbix agent config files.

Here''s what I have now:For debugging, I''d strongly recommend creating a test file, which you can do this simply with your existing Zabbix config. I''ve created a sample here that uses the head -n25 output you pasted - I suggest you fill in the rest: https://gist.github.com/1662040 Store it in lenses/tests/test_zabbix_agent.aug and then you can run: augparse -I lenses/ lenses/tests/test_zabbix_agent.aug (with your new lens under the lenses directory) No output means the lens has checked out fine and the output tree (in the bottom half of the test) matches the input file at the top.> And the augeas output (all empty): > => [/etc/puppet] # augparse /usr/share/augeas/lenses/contrib/zabbix_agent.aug > [/etc/puppet] # augtool -e ls /files/etc/zabbix/zabbix_agentd.conf > =Since the output of head -n25 works perfectly for me, I suspect the problem might be parsing something in the remainder of the file. Try running "print /augeas//error" from within augtool and see if you get /files/etc/zabbix/zabbix_agentd.conf listed. This wiki page explains how to parse the parse errors: http://augeas.net/page/Tracking_down_errors There are some other useful tutorials about creating lenses, the ambiguity problems you might hit and other subjects on the wiki: http://augeas.net/page/Main_Page If you manage to solve it, please do consider sending your new lens (and accompanying test) upstream to the augeas-devel list, we''d love to include it. Hope that helps. -- Dominic Cleal Red Hat Consulting m: +44 (0)7817 878113
