I did the same and only graph "Bytes Read/Written" is working. I don't see any errors in logs. Has somebody solution? I realy need this disk information.mvip wrote:Did anyone manage to get this working on any recent version of Cacti?
I followed the steps in the initial instructions, but can only manage to get "Bytes Read/Written" to work. I'm running on a FreeBSD 6.2 machine and I can successfully manage top pull the information with snmptable and snmpwalk

I've changed the Graph Template 'Device I/O - Load Averages'
Go to:[b]Graph Templates[/b] ->[b] ucd/net - Device I/O - Load Averages[/b] and cnag following 'CF Type' to AVERAGE:
AREA -> from LAST to AVERAGE
STACK -> from LAST to AVERAGE
STACK -> from LAST to AVERAGE
And it worked.
About the last template - 'Device I/O - Reads/Writes':
I've changed every 'CF Types' that was LAST to AVERAGE and it works.
I've also got the Graph Template 'ucd/net - Device I/O - ALL', which after changing all 'CF Type's from LAST to AVERAGE worked.
Are the graphs accurate after this changes?

Hello,
it seems I have the same problem like some others.
THe Reads/Writes graphs are not drawn.
I read this post, but couldnt find where something is wrong,
the snmpwalks on this post work all fine. Also all the other graphs in this script.
Can someone help to debug this?
cheers

ERROR: the RRD does not contain an RRA matching the chosen CF
I do not see "ucd/net - Device I/O" there. I see Karlnet, two Netware, two SNMP, and a Unix. I did import the XML files, but I never saw any definitive message about if that was successful or not. How would I find out? They do show up under Export Templates.dS_Jeffrey wrote:I figured this out. I was too used to using the script method for getting input.
For others who might need assistance this is the way i added it:
Management -> Devices -> <Machine> -> Associated Data Queries -> ucd/net - Device I/O -> *ADD*

Here's a new approach (but only for Bytes/Transactions) featuring Peak Usage and some nice optical layout: http://docs.cacti.net/usertemplate:grap ... disk_usage
I move diskio.xml for the resources/snmp_queries.gandalf wrote:Here's a new approach (but only for Bytes/Transactions) featuring Peak Usage and some nice optical layout: http://docs.cacti.net/usertemplate:grap ... disk_usage
When I then import the transaction xml I get.
CDEF

GPRINT Preset

Data Input Method
[success] Get SNMP Data (Indexed) [update]
Data Template

Any advice?
I thought I had everything cleaned out. I guess not. It would be nice if there was a way to clean out an import. I will try to get all the old disk io stuff out and see if I can get it to work this time.gandalf wrote:You installed over an existing DISK IO template set?
That's bad. I did not try that. Will require some thinking ...

Re: solved and new howto
I found that page and got a little farther.gruad23 wrote:I finally resolved my problems and made DISK I/O working on my cacti.
For those who will come here later and seek help: I put my experience in the following small "mini-howto"
http://www.goldfisch.at/knowwiki/howtos/cacti#disk_io
When I imported cacti_data_query_ucdnet_device_io.xml my "Associated Data Queries" section was empty, and there was a link to run it in debug mode. That resulted in an error about .1.3.6.1.4.1.2021.9.1.1 (an snmpwalk of that tree doesn't turn anything up, I need to back out to .1.3.6.1.4.1.2021 to see things). Now, that I/O template has disappeared and re-importing it doesn't make it appear. So, I guess I need help making that .9 branch appear (FWIW, .1.3.6.1.4.1.2021.13.15.1.1.1 does return ~24 values), and then figuring out where the template went and how to make it reappear.
i've got the same problem. even if i clean out all previous disk i/o templates i see the same message and i'm not able to make graphs from it.jbooks wrote:I thought I had everything cleaned out.
