Last obstacle I think

[manish686]

What I really think the data is not being fed into the rrd as a result no graphs . However please what the best can be done in this case? heres the graph error

RRDTool Command:

/usr/bin/rrdtool graph - \

RRDTool Says:

i am extremely sorry for giving u trouble .Actually I am quite new to cacti further for the bug reciprocated I didnot get anything worth to start with. Further I came across that even the cacti log files are completely empty.

[paulgevers]

Did you refresh the poller cache? Did that help?

[manish686]

nopes..!! it appears empty still...!! for data source debug mode I am getng this

Data Source Debug

/usr/bin/rrdtool create \

Hi,

Have run into this on several occasions and here's some of the fixes that work depending on the situation:
- Restart SNMP on the device
- Check that you can poll another graph on the server - if so, try doing a debug query on that
- Do a snmpwalk from the Cacti server on the device and confirm that you can get to it
- Check the OS version on the device against the other versions for devices you poll - i've had specific devices that wouldn't work in Cacti until they were on a later device version. This was an issue with the Device's SNMP stack

Hope this helps

The error

Code: Select all

ERROR: opening '/var/www/cacti/rra/localhost_load_1min_5.rrd': No such file or directory

already gives it away a little. The permissions for the user running Cacti are not set correct. Please check whether there is a .rrd file in the location the error specifies. I guess there is not.

Please adjust the permissions or create the file manually.

[Schnark]

I've seen this happen when the permissions on one NTFS folder are exactly the same as other ones and this was fixed through a combination of the suggestions I made above. That said, fully agree with checking the permissions.

[paulgevers]

Probably a very stupid question, but did you actually create a cron job to run the poller?
