thank you replay, yes,it works. I just test anoter method, in the template.erb file, write this <% memorysize.to_i*0.75 -%> ,it also work :D On Apr 27, 4:21 pm, Pair <pair...@gmail.com> wrote:> I''m Pair. > > On Sun, Apr 27, 2008 at 12:08:31AM -0700, huangmingyou wrote: > > > hello, guys > > in the puppet erb template ,I want get the vaule of the > > memorysize * 75%. but I don''t know ruby and erb. > > > the memorysize like "251.02 MB" ,how to change to a number like 170 > > somting. > > > maybe be the firset step is to delete the "MB" then math the 251.02 > > then get the integer ? > > puppet''s memorysize value is provide by facter. > > http://reductivelabs.com/trac/facter/browser/lib/facter/memory.rb > > * Your answers > * add custom facts > * write dirty code > * example > <% > val=memorysize.sub(/ MB$/, "") > val=val.to_f*0.75 > puts "#{val} MB" > %> > > -- > Pair <pair...@gmail.com>--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.

I do mine a little different in the fact that i need to calculate squid
memory assignment
so i want total system memory minus 512M and if the system only has 512M
i want it set to 32M
so something like:
def calcMem()
memory = ''''
memoryLess512 = ''''
File.readlines("/proc/meminfo").each { |line|
if line =~ /MemTotal\:\s+(\d+)\skB/
memory = ( $1.to_i / 1024 )
# Check if total memory is 512mb or less, if so set the output var to 32mb
if not memory <= 512
memoryLess512 = ( memory - 512 )
else
memoryLess512 = 32
end
end
}
return memoryLess512
end
Facter.add("mem_minus_512") do
setcode do
calcMem
end
end
Cheers

thats good for me, because I do this for squid.conf''s cache_mem too. but now,I only do some math like this : totoal_memory_size * 0.45 .
