Trouble creating .rrd Files

[RedGiant]

Hi,
I just installed cacti via apt on a Ubuntu workstation. Everything went smooth and the graphs for the default data sources look great. Here is my problem...

I've tried to add an "Interface - Traffic" graphs to the default device (Localhost) but they are just coming up as broken images.

I've looked in the 'rra' folder and there is no .rrd file for those sources.

I've gone through the logs but have been unable to identify the problem. Does anyone have any idea why these are not working or a way I can trouble shoot this problem?

Don't know if this will help (I just installed cacti for the first time this morning), but I had a similar situation on a Debian Sarge fresh install. What I found was that the RRD files were not being created because the script (or whatever) was creating to DS for traffic_in and traffic_out, so I would get an error message about having a duplicate DS. I just copied and pasted the rrdtool create line, took out the duplicate items, and it ran ok after that.

Follow-up noob question: how do I tell what version of cacti is installed?

Thx,
dc

I noticed that and did the same thing but now I just get blank graphs.

No data is getting polled by the script.

Had an install running for more than a year (I think I just forgot how I did it)... went to upgrade and had another person helping. We hosed it and found ourselves starting over.

This is day 3 of starting over. We have tried a bunch of stuff? This wasn't so difficult to get the first time???

Same symptoms... no .rrd files. I looked at FAQ and ran 'php poller.php' in the cacti folder.. it doesn't give errors, It just spits back that it should be run from the command line.. so I assume everything is fine with permissions.

Any help??

[RedGiant]

This is driving me crazy, its happening on both my ubuntu and debian sarge workstations.. am I missing something very obvious or what???

Please apply all the patches and then review the Data Sources created by the templates. In addition, please post 1 pass from the poller using DEBUG.

Ok downloaded and ran the patches. Didn't seem to help

Checked the Data Source and I have a question. What values should go under custom data? There are 3 fields, index type, index value, and output type id. Originally I left all of these blank.

Here is the output from poller.php...

Thanks for all the help so far, I hope I get this working soon

Any thoughts? The traffic graphs are still showing up blank.

Even after starting from scratch and apply the patches.

[TheWitness]

I think I understand why now your Interface graphs are not working. Please follow the method below:

1) Create a Device
2) When Editing the Device, add the "Interface??" Data Query to the host. Use the "uptime goes backward" reindex method
3) Once it's built, it should show entries and rows.
4) Select "Create Graphs for this Host"
5) Select the interfaces you want graphed and from the drop down, select the Graph Type.
6) Press "Ok" or "Save" (can't remember)

TheWitness

EDIT: Oh, one more thing, delete your buggered up Data Sources and Graphs.

[RedGiant]

How come none of the interfaces show up in the drop down menu when I try and add a graph? The only way I can create a Interface graph is by creating my own Host Template with Interface already in it...

Here is the output from the 'Data Query Bebug Info'... maybe it can help..

Try this and post your output:

snmpwalk -c public -v 1 <your_host_ip> .1.3.6.1.2.1.2.2.1

[RedGiant]

All I get is "End of MIB"

[TheWitness]

RedGiant,

One of a few things is happening:

1) Your device does not contain the standard if-mibs
2) Your devices has them, but there is an ACL preventing your from accessing them.
3) Your devices snmp agent is buggy.

If the answer is 1) then you have to create your own data query. The best way to find this is to perform the following:

snmpwalk -c <your_community> -v <your_version> <your_host>

Post the results.
