I looked at doing data queries, they seem to be a right pain in the ass. I did have some test code floating around somewhere but cacti just didn't seem to want to record the data. I was toying with it for doing disk space and disk i/o.chrisru wrote:Hey Claymen,
Firstly the wmi graphing is perfect, would it be hard to build data queries for these graphs? after having a look at how you would do that I got stuck because it appears the script needs to provide a couple of methods the first being a count query to just provide a count and the second seems to be for selecting results by index. Have you looked into this at all?
I don't think the script as it is would be the best to for using as a base for data queries. I can think of a few ways to do it but I didn't really have the time to look at it.
All other graphs work fine.
Cacti 0.8.7e
WMI works.
WMI memory graph works too.
Disk I/O on 2 different hosts selected, both don't write the rrd file.
Poller in debug comes up with no errors.
Bit stumped here as all other rrds are created fine, and I added a bunch of tcp ones yesterday, and they work too.

That's a bit weird. It's not unusual, some days I really have no idea why cacti refuses to work. Can you pull any further details from your cacti.log on high or debug mode?JorisFRST wrote:Updated everything to 0.0.6 and now get

Thanks,
fixed it. The new error was basicly I f* up my security on the authentication files
with messing too much about.
I did fix the Disk I/O Issue now too,
looks like in the Data Input Methods WMI - Disk I/O I had
DiskReadBytesPersec 2 times
and DiskWritesBytesPersec also 2 times.
Same thing in Data templates Windows - Disk I/O (WMI)
After deleting the doubles that pointed to the wrong value (diskquelenght) everything works now.
Thank you so much, this exercise made me learn a bit more about the cacti scripting, as I had no clue.
(and linux too, had alot of trouble compiling wmi 1.3.5 on Centos 5.3, only to see that I was doing it the difficult way, as there's now a makefile with the last releases, so anybody that wants the wmic and winexe compiled for this, I'm happy to send them or include them here)

Hi everybody,
I have a very obscure issue using the wmi templates. I use these templates mainly to monitor cpu activity on virtual machine that run on esx servers. Everything used to work fine ... until the night between monday and tuesday were all graphs started to report NaN as value. I investigated since then and found out that the wmi part of things seems to still work like a charm and report meaningful values. I have looked in the cacti log file and even find the following (On newly recreated graph just to be sure...)
but the graphs I get are desperatly empty
Do any of you have any idea what could be causing this ?
I'm also attaching the rrd file because I don't quite understand it's content related to the insetrt I see in the log. Btw If I try to run the updates by hand (with differents timestamps) it seems to work.
Thanks for your help

Just looking around at some of the other cacti plugins and I have realised the the discovery plugin has the ability to use templates. Could that be an option instead of data queries?

Windows Memory usage WMI Template problem
implemented wmi and got it up and running, script runs on command line and gives values back.
Now i want to activate the windows memory usage template (v. 0.6 from first posting)
and get:
i am not a template specialist. Can someone put me in the right direction, whjere i can digg after the source of the error?
