Hello,
I have been doing this recently using a restart condition polling a
ruby-script. This was a quick-fix to get me through the weekend so
please excuse the style :) ::
First have this custom PollCondition loaded somewhere in your configs:
******* BEGIN *********
module God
module Conditions
class LogWatch < PollCondition
attr_accessor :log_file, :above
def initialize
super
self.log_file = nil
self.above = nil
end
def valid?
valid = true
valid &= complain("Attribute 'log_file' must be specified",
self) if self.log_file.nil?
valid &= complain("Attribute 'above' must be specified", self)
if self.above.nil?
valid
end
def test
begin
seconds = `/path/to/exec/script/below #{self.log_file}`
seconds.to_i > self.above
rescue
true
end
end
end # LogWatch
************ END *************
Then I used this script which right now is completely external to the
God stuff (but I'd like to integrate it if i ever had time)
******** script BEGIN **********
#!/usr/local/bin/ruby
#
# Print the number of seconds since the last log statement in the
given log
#
# $Id:$
#
require 'rubygems'
require 'activesupport'
require 'date'
log_dir = "/var/rails/log"
if ARGV.length != 1
puts "You must provide ONE log file name to check!"
exit 1
end
log_file = ARGV.first
if ! File.readable?("#{log_dir}/#{log_file}")
puts "Cannot read #{log_file}"
exit 1
end
begin
t = File.mtime("#{log_dir}/#{log_file}")
last_log_time = DateTime.parse(t.to_s)
rescue
last_log_time = DateTime.now
end
# convert to DateTime
diff = (Time.now - last_log_time.to_time).to_i
puts diff
******** script END **********
Then in my God watch I add the following poll condition:
******* watch BEGIN *********
w.restart_if do |restart|
restart.condition(:log_watch) do |c|
c.log_file = "really_important.log"
c.above = 300 # 5 min (in seconds)
c.notify = 'warnings'
end
end
******* watch END *********
