For one more time I am a bit confused and I need your help please. I use Cacti Version: 0.8.7g, Plugin Architecture Version: 2.9 and Autom8 0.35b6 and I noticed that sometimes I had double graphs. I thought that maybe it was a matter of some difference in the data sources so I tryed to have a test with a specific host.
I deleted every traffic graph with all related data sources and I tried to reindex this device just to recreate every traffic graph based on autom8 rules. After this I had 2 graphs for every interface with a separate data source and rrd file each. I noticed that the names of the first graphs was based on the "data query -> In/Out Bits (64-bit Counters)" format (|host_description| -Tr- |query_ifName| - |query_ifAlias| ) and are fully functional and on the other hand the doubled graphs had names based on the data template - interface traffic (|host_description|-|query_ifName|-|query_ifAlias|-Traffic) and they remain for ever empty. I can upload a screenshot if requested.
I read the manual to clear what is the purpose of "data templates" and "data queries" but I am still in a grey cloud. Any help would be appreciated!
*last edit: None of my graphs now is functional.
thank you!

I already saw similar complaints in the past.
ALL of them were related to different graph templates for interface traffic being used.
E.g. in case you graph 32 bit counters, a 64 bit counter graph of the same interface is a second and different graph.
But nevertheless, here's how to start debugging:
- select a single host were issues are happening
- delete all interface graph Data Sources along with the related graphs
- enable AUTOM8 logging (see Settings) and set logging level to a high value
- visit the device in question on the "Host" list screen
- check that device
- wait until the poller has completed (we do not want to see poller related entries)
- select action "Apply Autom8 Rule(s) to Device(s)", do this twice (allow for some seconds between both runs) to find out, whether two graphs are created
- complete this task before the next poller run
- grep for "AUTOM8" in log/cacti.log
This is a quite detailed trace of what cacti is doing here. In case two graph rules apply or a second graph is created from the second run, we should see that here.

Hi Gandalf,
Here is my outcome:
1. In my cacti I have deleted the "32 bit counters" data query to avoid problems because we use it never. So the creation of such a graph is impossible.
2. I deleted all graphs for the test host, I did all log setting both with HIGH and DEBUG level as you said but after the rules applications nothing was logged in my cacti.log despite the creation of new graphs (included the doubled).
3. I noticed that autom8 can write in my cacti.log so I guess it is not a matter of rights.
4. I have 3 graph rules defined for 3 different kind of devices but none of them comes in conflict with another (checked many times with the "view matching hosts" filter).
5. All defined rules are specified to use "64 bit counters" data query.
6. All doubled/wrong graphs are created at the same time with the right graphs. We can notice it also from the graph id number which are all serial.
Do you thing it may be a matter of wrong autom8 patch application? How can I check if everything is patched ok?
I attach you a screenshot with the new created graphs sorted by ID. Notice the order that are created.

I noticed that this issue exists only for one kind of my devices. The bras boxes. So I was testing my rule but with no luck. I attach you this rule just to check it. Do you think it is may be a matter of a bad rule? The matching graphs and hosts looks right.
I want to graph:
all Bras interfaces that is up,
are Ethernet or ATM or POS
and are NOT subinterfaces, tunnels, mpls, or l2tp tunnels.
*the attached is a new rule that I was testing with the same luck.
Please remove the "." test for a try. I fear, that regexp may have issues with that.
To know better, we still need the AUTOM8 debug ... This will show the whole regexp that is derived from your rule

ok Gandalf the log was just a matter of file rights. I thought it was the cacti user that was needed to has write access . I attach you the debug log of my AUTOM8 actions. In that log, you will notice that I have only 2 rules enables (the ones that have the problem.). Finally I added back the "." after I saw that it wasn't the cause of the problem.
Mystery solved!!!!Too much pain for that... Finally it was a matter of "wrong" rules. All my rules was based on "ifdescr". The problem was that a juniper Bras when returns it's interfaces , for some reason it gives two times one interface. For an Ethernet interface for example gives one record with iFtype: "ethernetCsmacd" and one with iFtype:"l2vlan"......So autom8 was reading two intefaces...
So I created rules based on ifType and worked fine!
sorry for the whole mess and thanks for your support!
