Script Need to check disk space on remote servers

I know i could always buy a program to do this but wheres the fun in that?
so I need a program that will go through a list of servers and then a list of their drives and check to see how much free space is left on those drives, from their if it is anything less then 30GB i need it to send an email to me.
i am using psexec to access these remote servers and run cmd. then to email myself i am using postie.
the problem i am having is wrapping that all up in a if-then-else command that will look for the specified free space. It doesnt work right now beacuse for whatever reason it is bring back a true statement when the statement is false because i know the server its checking is more then 30GB free.
This is what i have so far:

@echo off

for /f %%S IN (serverPClist.txt) DO (
echo Checking drives on Server %%S...
for /D %%D IN (C D F G H I J K X V E) DO (

psexec \\%%S cmd /c if exist %%D:\* dir %%D:\ | findstr /c:"bytes" > %temp%\%%S-%%D.txt
)
)


color 0D


for /f %%S IN (serverPClist.txt) DO (
echo. & echo.
echo ********** Displaying output for server %%S... **********

for /D %%D IN (C D E F G I J K) DO (
for /f "tokens=1,2,3,4" %%F IN ('if exist %temp%\%%S-%%D.txt type %temp%\%%S-%%D.txt') DO (
if /i "%%G" == "Dir(s)" echo For the %%D: drive: %%H bytes free space.
if /i "%%G" == "bytes" echo For the %%D: drive: %%F bytes free space.
echo.
)
)
echo Done!
)
echo Generating HTML...

REM this part of the script generates an HTML file with all the relevant information
REM and then launches it using the default browser.

set FileName="C:\Report.html"
echo ^<HTML^> > %FileName%
echo ^<HEAD^> >> %FileName%
echo ^<TITLE^>Free Space on NRCE Servers^</TITLE^> >> %FileName%
echo ^</HEAD^> >> %FileName%
echo ^<BODY^> >> %FileName%
echo ^<CENTER^>^<FONT SIZE=6 COLOR=BLUE^>Free Hard Drive Space Report^</FONT^>^</CENTER^>^<BR^> >> %FileName%

for /f %%S IN (serverPClist.txt) DO (
REM mark the server
echo ^<FONT SIZE=4^>^<B^>%%S^</B^>^</FONT^>^<BR^> >> %FileName%
for /D %%D IN (C D E F G I J K) DO (
for /f "tokens=1,2,3,4" %%F IN ('if exist %temp%\%%S-%%D.txt type %temp%\%%S-%%D.txt') DO (
REM add a line for the drive and free space
if /i "%%G" == "Dir(s)" echo ^<FONT SIZE=3^>Free space on ^<B^>%%D:^</B^> drive: ^<B^>^<FONT

COLOR=GREEN^>%%H^</FONT^>^</B^> bytes free^</FONT^>^<BR^> >> %FileName%
if /i "%%G" == "bytes" echo ^<FONT SIZE=3^>Free space on ^<B^>%%D:^</B^> drive: ^<B^>^<FONT

COLOR=GREEN^>%%F^</FONT^>^</B^> bytes free^</FONT^>^<BR^> >> %FileName%
)
)
REM mark some spacing lines into the HTML file
echo ^<BR^> >> %FileName%
)

echo ^</BODY^> >> %FileName%
echo ^</HTML^> >> %FileName%

REM launch the HTML file

set positive=1
set amount="30,000,000,000"
if %%f leq %amount% set violation=1
if %%h leq %amount% set violation=1
echo %violation%
if %violation% equ %positive% postie -host:(SMTP SERVER) -to:(MY EMAIL) -from:(NETWORK EMAIL) -s:"Server Report" -msg:"THERE IS A VIOLATION!" -a:"C:\ServerReports\Report.html"
echo Done!

If anybody else has anything better plz show me, otherwise i will keep playing around with this coding.

enable snmp and install nagios

maybe i should of mentioned that this is going on a windows machine

Server 2003 hacks has a script to do this, but then again spiceworks does this and makes it look pretty! :wink:

You can check this via SNMP or WMI.

You could use AutoIT's DriveSpaceFree function:

Code:

---

$var = DriveSpaceFree( "c:\" )
MsgBox(4096, "Free space on C:", $var & " MB")

---

your missing a chevron:


set FileName="C:\Report.html"
echo ^<HTML^> > %FileName% <<<<<<
echo ^<HEAD^> >> %FileName%
echo ^<TITLE^>Free Space on NRCE Servers^</TITLE^> >> %FileName%

If that helps at all?
:P

and and ensure you have something near the start that sets violation to 0, otherwise you will have to manually reset it every time... even if there is now enough space...

and this line msg:"THERE IS A VIOLATION!" -a:"C:\ServerReports\Report.html"
should read msg:"THERE IS A VIOLATION!" -a:%FileName%
or at least msg:"THERE IS A VIOLATION!" -a:"C:\Report.html"

is there any security risks with spiceworks since its free?
does it phone home at all?

This has been done with bells on here:

(as a vbscript)

Trying to build HTML with windows batch files is evil! Too many ^s!
