Obtaining memory usage of a process and string manipulation

[xga]

Hi Guys,

I'm trying to write a dos batch file to monitor the memory usage of a certain process and once it reaches a certain threshold, restart the process.

The code below reports the memory usage of process.exe in kilobytes. E.g. 100,000

Code: Select all

for /f "tokens=5,6 delims=: " %%A in ('tasklist /nh /fi "imagename eq process.exe"') do echo %%A

So my question is, how do I convert that string result to an integer so that I can perform a "if gtr than" process? Do I need to strip the comma from the string first?

Any help would be greatly appreciated!

Thanks in advance.

CMD math is limited to 2^31 or around 2.1 gb

Is that going to be a problem?

I see that it reports in K without bytes as you said.

This sort of thing should work - I don't see the need for the delims in my window in Win7.
You might need the /f switch in taskkill
(Untested)

Code: Select all

@echo off
:loop
set "task=process.exe"
for /f "tokens=5,6 delims=, " %%A in ('tasklist /nh /fi "imagename eq %task%"') do (
if %%A%%B GTR 999000 do (
taskkill /im "%task%"
start "" "%task%"
)
)
ping -n 60 localhost >nul
goto :loop

EDIt: added delims

No, I'm only wanting to monitor the memory up to 1.5 GB or 1,500,000 KB.

Thanks foxidrive. However this still will not work as if the memory usage was at 500 MB, tasklist reports it as "500,000" including the comma. As far as I am aware, the "IF" command cannot perform comparisons with values when they have a comma in them, so that's why I was thinking that I would have to somehow strip the comma from the value first.

Any thoughts?

Silly me. I added the delims to the code above - try that.

It should present the number without a comma - but I don't know what the tasklist outputs when the command uses more than 1 GB of RAM.
