Monitoring Disk I/O (Write/Read)?!

[prenat]

Hi!

Juste a little question, because i don't find what i'm searching on theses forums.
I'm looking for a script/template would be able to make graphs for each drive (c:, e:, ...) of several servers runing under win2000, with BytesRead /s and BytesWrite /s data source.

i'm tried modify the ss_host_disk.xml and ss_host_disk.php to add the following OIDs in the array...
.1.3.6.1.4.1.9600.1.1.1.1.15 --> for the BytesRead / s
.1.3.6.1.4.1.9600.1.1.1.1.18 --> for the BytesWrite / s

...but it's seem not easy as i thinked.

Sorry for my very bad english

If someone have a solution i give him a kiss !
Thank in advance
Regards,

Julien

Hi Julien,

some questions:
* What operating system are you running the cacti server on (Windows, Linux ...)?
* What flavour of Windows do you try to monitor (Windows 2000, Windows 2003 ...)?
* Are you allowed to install additional programs on your Windows systems?

Kind regards and greetings from Austria

Thank you Thomas !

Maybe you want a kiss

here the responses at yours questions :

- I'm running cacti server on a windows2000 server (with SNMP - Informant STD installed)
- I'm trying to monitor only windows2000 servers (with SNMP - Informant STD installed)
- and YES, i can install programs on the windows server

I hope there is something existing for this kind of need.
Thank you very much for your help !

Best regards,

Julien

Hi Julien,

most users want to query Windows boxes from Linux - there is a solution to monitor all kind of performance monitors.
For Windows-Windows you'll have to use WMI to get this information.
Have a look at http://forums.cacti.net/viewtopic.php?t=2907 to have an example on how to get the disk utilization. I'm not familiar with WMI but I'm sure you can find the disk I/O rate on the internet.
Another place to start is http://forums.cacti.net/viewtopic.php?t=1474.
It's a pitty your Cacti server isn't running on Linux. With NSClient there is an easy solution to graph all available performance monitors.

Hope this helps

Thank you.

I know that windows environement (windows, IIS...) isn't the roll's roll's for running Cacti.
BUT i'm in trainning for the moment and the enterprise want to put cacti under windows
I already red the topics you had copy-paste me but i'm not very sure of myself.. that's why I'm searching someone with the same problem, to exchange experiences.

but, why I can't use OIDs to do monitoring of discs server?
indeed, the available disc space work like that. ! no?

Please, help me, i must finish this work at the end of the week

Hi Julien,

I'm sorry but I can't help you any further. I've never used SNMP Informant to create graphs.
I think you started at the right place to copy and modify existing data queries to fit the SNMP Informant OIDs. Unfortunately indexed OIDs aren't easy to get data from.

I'm very sorry that I couldn't help you
