Cacti version 0.8.7g (linux)
Not aware of any changes made at the time this started, all but one interfaces on a single switch have no graphing for traffic, all other graphs on the device are fine
tried clearing poller cache
rrd files look good (perms/ownership), last date modified for traffic was about a week and a half ago for the non-updating rrds
"rrdtool info $example_traffic_RRD" results with min/max all look good and within boundaries. step=300 and heartbeat=600
Debug on graph management shows DEF to be identical between working and non-working graphs (except for the RRD file path obviously)
cacti log "debug" - not showing "traffic queries" for all except the one interface. all other interface stats are good (unicast packets, uptime, etc)
data source lists yes in the active column for the non-working graphs
Its as if cacti is just ignoring these data sources for some reason. How do I figure out why they are not graphing or at least get them graphing again?
# php -q poller_reindex_hosts.php --id=9 --debug
WARNING: Do not interrupt this script. Reindexing can take quite some time
DEBUG: There are '1' data queries to run
DEBUG: Data query number '1' host: '9' SNMP Query Id: '1' starting
DEBUG: Data query number '1' host: '9' SNMP Query Id: '1' ending
This has made no difference. Is this what you meant or is there another index you refer to?
I have also tried running the "realtime" plugin on one of the graphs in question but it never generates a graph (just a broken image) as it does for the rest. It's weird that the port 16 traffic graph is still updated as is noted in the cacti log when debug level is set. The other traffic graphs for this host might well as never have existed after December 3.
It is not too terrible to delete the graphs and data sources and then re-add them all but it would be nice to figure this out as I can't see how this could be anything other than human intervention that could have caused this condition which I would like to try and prevent from happening again.
No, the missing ones are not there.
Search for "Traffic" on the host in question shows only a single port twice (presume by OIDs one is for "in" the other is for "out").
Search for "Traffic" on other similar hosts shows all ports
Is it an option to completely drop that data query from the host. Then delete all related data sources for that host and re-add the data query afterwards?
R.
Yeah, any course of action is acceptable. Can you help me with the process you described? I can delete the data sources but how do I "drop the data query" from the host?
Ok, I have no idea what is going on here. This is what I have done so far.
deleted the host in question and deleted all related data sources.
I went in and deleted all rrd files as well for this host. This, I believe, puts the server in a state of "cacti has absolutely no knowledge of this device" condition. I am thinking I should be good now
Add device
Fill in basic info (name, ip, host template)
Create Graphs For Host and choose the two Graph Template options for this host type and select all of the physical ports in the Data Query for Interface Stats. I choose graph type 'In/Out Bits (64-bit counters w/Total BW)' as was done for all of the other identical switches. Hit create. No problems.
Now the two host template graphs show up in the data sources and the "traffic" data sources show up.
look at the file system and only 2 rrd files exist for this host, the host template ones, there are none for port/traffic.
I am starting to get the feeling that my associated graph template for the "interface stats" Data Query is bad or something.
Yeah, apparently my associated graph template for the data query is faulty. I had created a new one called "In/Out Bits (64-bit Counters w/Total BW)" that would basically be the same as the non 64-bit equivalent but when I edit it the Associated Data Templates for "traffic_in" and "traffic_out" data sources are both stuck on "ifInOctets (Bytes In)". If I change them and hit save they both remain on "ifInOctets (Bytes In)". I would like to use 64-bit counters and have bits with total bandwidth on the graphs. Am I going about this the wrong way?
Can you indicate where to enable debug? See the attached screenshot for what I am talking about. The "Associated Data Templates" will not stay as the 64-bit counter version.

Hi
I've the same problem as jkrejc.
I've added a new associated graph template called "In/Out Bits with Total Bandwidth 64-bit" and changed the traffic_in and out datasource to the 64 bit counters.
After hitting save both values return to "ifInOctets (Bytes In)".
If I change the datesource settings for one of the shipped associations the changes get applied.
DEBUG Output:
"In/Out Bits with Total Bandwidth 64-bit":
