ucd/net snmp Device (Disk) I/O templates - Updated - v3

[flowinh2o]

Since Solaris does not seem to support disk io load averages I have made a graph template that combines the two that it does; Device read/write and Bytes read/writes. I have attached the graph template and a sample graph for all who are interested. Enjoy.

As many have asked before, what is supposed to go into the Index field parameters when creating a graph. I get everything setup just fine but i think this is the missing piece because i always get "nan".

I am still having trouble getting the HD IO to graph with the given data.

From what I am understanding the 3 values should be

Integer
17
Counter (?)

But I obviously know this is wrong. If anyone has experience getting this to work can you please provide some insight as to how to fix this issue.

Thank you.

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*

then create the graphs

Management -> Devices -> <Machine> -> *Create Graphs for this Host -> Data Query [ucd/net - Device I/O] -> Select Drive -> Select Graph Type -> *CREATE*

Hi

Is there a way to resolve the devices in these graphs into mount points ?
like ssd39= /export

Thanks. Works fine.

I have tried like 100 times now to get this to work.

How ever I add stuff I always end up with

ERROR: opening '/var/lib/cacti/rra/machine_15min_loadavg_896.rrd': No such file or directory

But I don't even add a loadaverage, I only want reads and writes on the device io. Have tried both the templates from the OP and the one merging all.

What am I doing wrong.

Either something is broken or I am doing something wrong.

What order should you do everything in?

One time I got the:

ERROR:the RRD does not contain an RRA matching the chosen CF

I changed AVERAGE to LAST where told to, then I was back to file not found. Why is it trying to create a loadavg file, when I only ask for the reads and writes.


I am getting really frustrated.

I got this template to work, thanks. However, it required creating the data query template as described on page 5.

Thanks.

I tried the package from the original poster and the one provided by gandalf and I think I tried every thing recommended on one of this seven pages, but it still does not work.

I can import without errors and I see the new templates and graphs, but when I actually create a graph (console -> graph managment -> add and choose a host and the ucd/net - Device I/O - Reads/Writes) I get the following error.

HI,


I'm trying to get these template working for me ... After 2 hours of searching why nothing works, I see than ... Gentoo need to comile net-snmp with "diskio".


Now, it will work for my server. But, on my workstation, I get these results on creating graphs for all the list of detected "disk?" :

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"

Hello,

im trying to get this running, followed all the tips in this thread but
only the Read/Written graphs are created,but still without any drawings.
The Load Average and Reads/Writes are not created at all.

My data qzuery looks like on the pictures above.
A verbose query gives me no errors.

Where else can I debug whats not working?
A snmp query to the linux host also give me data

one of the that not get written i get these message:
