require the code below in a .god config file
and you can use the VirtMemoryUsage as you would use the MemoryUsage
condition
It patches the pollers to expose virtual memory usage.
Have fun with it
module God
module System
class SlashProcPoller < PortablePoller
def virt_memory
stat[:virt].to_i * @@kb_per_page
rescue # This shouldn't fail is there's an error (or proc
doesn't exist)
0
end
end
class PortablePoller
def virt_memory
ps_int('virt')
end
end
class Process
def virt_memory
@poller.virt_memory
end
end
end
module Conditions
class VirtMemoryUsage < MemoryUsage
def test
process = System::Process.new(self.pid)
@timeline.push(process.virt_memory)
history = "[" + @timeline.map { |x| "#{x > self.above ? '*' :
''}#{x}kb" }.join(", ") + "]"
if @timeline.select { |x| x > self.above }.size >=
self.times.first
self.info = "virtual memory out of bounds #{history}"
return true
else
self.info = "virtual memory within bounds #{history}"
return false
end
end
end
end
end
