I had this problem, too.

Data Templates --> Interface Traffic:
Traffic_in and Traffic_out doubled.

And I use Cacti v0.8.7.b with PA v2 fresh installation (not upgraded from older version)

I deleted the ones with higher view_rrd_ids and after addin the device again and generating graphs for the interfaces everything seems working now.

And now again after using "Cisco 7200 Template" from here: ... sc&start=0

Dublicate Problem in:
Data Templates --> Interface - Errors/Discards

Don't know if anyone is still monitoring this thread, but it seemed like a good place to post my issue.


Monitoring Brocade switches. Fan and Temp graphs are working just fine, but the interface RRDs are not being created.

I was getting an error about the minimum being less than the max, so I enabled the minimum value in the data template. This cleared up this error:
CMDPHP: Poller[0] Host[7] DS[58] WARNING: Result from SNMP not valid. Partial Result: U

None of these are doubled, but the RRDs just aren't getting gen'd.

Hi! Newbie here... :oops:

I'm asked to create a new Interface - Traffic graph for a newly created device. Each and every old Interface - Traffic graphs are working fine but I can't get to make a new one work (with any device, not just the new one)!

Since I just took on Cacti's internal support (hence the newbie reference :wink:), am I right by thinking that these old graphs were created before someone, for whatever reason, added a second traffic_in Data Source Item (resulting in 3 : 2 × traffic_in and 1 × traffic_out)?

I previously made this terrible mistake :o of removing one of the traffic_in item which broke all graphs and don't want to repeat it... I thought that maybe creating a new Data Template (labelled Interface - Traffic (New)) and new Graph Template (labelled Interface - Traffic (bits/sec) (New)) would do the job but RRD seems to keep on using the old Data Template ("ERROR: Duplicate DS name: traffic_in").

What am I missing? I searched the web and this forum and tried to apply the suggested solutions but with no luck :(. Also read somewhere that I could simply rename the unnecessary Data Source Item before deleting it... Since I don't wanna mess the whole thing (again :cry:), a detailed (newbie-proof :wink:) answer would greatly be appreciated.

Thanking you in advance.

NOTE: Using version 0.8.8b
