Cacti not creating .rrds - 0.8.7b

[alduin]

My cacti installation was recently upgraded to 0.8.7b but this problem was occurring prior to that, on 0.8.6j. I'm running cacti and spine (both from source) on Ubuntu 6.06.

When I create a new device from a device template and add graphs to it ("In/Out Bits" and "In/Out Errors/Discarded Packets"), the devices and graphs are created without a problem.

The next time the poller runs, however, the .rrd files aren't created. Going to the "Data Sources" page shows all of them in the list, and there's no error message reported in the debug output for any of them. In fact, I can take the rrdtool create line that is provided in the debug output and use that as my poller user to create the .rrd file without a problem. For example:

Code: Select all

Data Source Debug

/usr/bin/rrdtool create \

RRA:MIN:0.5:1:600 \
RRA:MIN:0.5:6:700 \
RRA:MIN:0.5:24:775 \
RRA:MIN:0.5:1440:3985 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:1440:3985 \

RRA:LAST:0.5:6:700 \
RRA:LAST:0.5:24:775 \
RRA:LAST:0.5:1440:3985 \

That works, and creates the .rrd file in the right place with the right permissions. When spine runs on the next poll, however, the data source isn't updated. A tcpdump shows that the SNMP queries are being done to the device in question, but the .rrd just isn't created.

Debug logging shows that the poller is trying to create and update the rrd file:

Code: Select all

I have other data sources that are updating just fine, and I've checked to make sure I don't have the duplicate data source issue. I'm pretty much at the end of my rope here. What could cause behavior like this?

Just to rule out a problem with my distro's rrdtool install, I built and installed rrdtool from source and pointed cacti at the new binary. No change.

I install cacti 0.8.7b have same problem
