From 9c603d8267c0a511968a8a553d7fa0b2d5bf9b73 Mon Sep 17 00:00:00 2001 From: "Chris St. Pierre" Date: Mon, 25 Mar 2013 13:31:21 -0400 Subject: Handle FAM monitor failures more gracefully: * Where possible, create the file or directory that is about to be monitored. This ensures that content can be added later without need to restart Bcfg2. (Otherwise, adding the monitor would fail, and so when you did create the file in question, bcfg2-server would never be notified of it.) * When not possible, give better error messages. --- src/lib/Bcfg2/Server/Plugins/NagiosGen.py | 24 +++++------------------- 1 file changed, 5 insertions(+), 19 deletions(-) (limited to 'src/lib/Bcfg2/Server/Plugins/NagiosGen.py') diff --git a/src/lib/Bcfg2/Server/Plugins/NagiosGen.py b/src/lib/Bcfg2/Server/Plugins/NagiosGen.py index c39bd4c42..466665382 100644 --- a/src/lib/Bcfg2/Server/Plugins/NagiosGen.py +++ b/src/lib/Bcfg2/Server/Plugins/NagiosGen.py @@ -5,26 +5,9 @@ import re import sys import glob import socket -import logging import Bcfg2.Server import Bcfg2.Server.Plugin -LOGGER = logging.getLogger(__name__) - - -class NagiosGenConfig(Bcfg2.Server.Plugin.StructFile): - """ NagiosGen config file handler """ - - def __init__(self, filename, fam): - # create config.xml if missing - if not os.path.exists(filename): - LOGGER.warning("NagiosGen: %s missing.
