cannot create new graphs / no new rdd files created

Yea, you have to look for a rrd file that is either missing or not updating. Did you modify any data templates or delete any devices/data sources during the process?

I am researching this issue with the developer of RRDtool. I have identified situations where the rrdtool process will exit prematurely. Unfortunately, I don't know enough about the product to assess the type of error that would cause that and how Cacti would be breaking it or if a user could actualy do so.

More to follow. You have a workaround for now.

All,

I have received a patch from the rrdtool author for 1.2.10. I will also get a patch for 1.0.50. I need people to test.

I made the changes you proposed and if I run the poller.php with the root user a lot of rrds are updated correctly (not all but better than any), but if I run the poller.php with a normal user (rights are correctly) it don't updates nothing.

When I run the php with the root user I see some pipe problems, and some rrds are not updated, they have 4 data source items each one.

After updating net-snmp to 5.1.3 (actually I was trying to compile PHP to version 4.4.0 so due to a ot of errors during ./configure I updated a lot of other components too) my Linux box stoped updating the rrd files.

I checked and double checked all paths in the Settings page but the rrd files still wouldn't update.

I updated rrdtool to 1.2.11 (a today's release) with no luck.

So I finally thought of trying 1.2.10 with your fixed files and the rrd files all of a sudden started regenerating!

To make a long story short, the fixed files work

I have the same problem today it looks like the poller is running but the rrds stop updating.
I was with rrdtool 1.2.11 and also try 1.2.10 with the patch but the only thing that help was to truncate the poller_output table
btw I found more then 500000 rows in this table before I truncate it

Thanks

This problem started for me today, even though the last time I upgraded any software on the server was 2 weeks ago.

I had been running rrdtool 1.2.6. Reading the patch notes (which read like it incorporated the patch Witness provided), I upgraded to 1.2.11. This did not solve the problem.

As suggested, I commented out the rrd_init and rrd_close lines in poller.php and the graphs appear to be working now.

Can you clarify the downside of commenting out these lines? Am I going to see slow growth of zombie processes? I'd say we're still looking for a fix to rrdtool.

Should be no zombies. It may slow polling a bit. I am disappointed that the upgrade did not help. It would "appear" to be a shared library issue in your version of *nix. Therefore, you will have to keep it in place for a while.

Please view attached file, I am having a very similar problem and have tried all suggestions.

Thanks

The problem you have is that you are using a miffed up procedure. To get "Traffic Graphs" you do the following:

1) Create a Host
2) Add the "SNMP - Interface" Data Query
3) Use the Reindex Method "Uptime Goes Backward"
4) Once you get the "Rows..." information back, goto "Create Graphs"
5) Select the Interfaces to Graph
6) From the Pull Down, Select the Interface Graph Type to Create
7) Hit the "Create" (?) button

Do it again for other Interface Graph Tyes

Sorry for all the frustration....

No Frustration, it is actually very intrigueing to use this product. I just wish I knew more about all items being used, but I am learning slowly.
Thx for your help so far.

The problem is the trailing \ at the end of rrd file creation command.
