Cacti well running but no graphs :(

[aurel102001]

Hello, i am actually running Cacti on my Windows XP machine. But strangely, i don t have the graphs, it only shows the name (see attached); but strangely it is working on another PC. Help please, monitoring is working as well as discovery, but i need to see graphs !

Any idea ?

Search is your friend!

You have a NTFS permission problem. double check the security on rrdtool.exe, cmd.exe and all the cacti files have IUSR_COMPNAME.

[aurel102001]

Ok, I have made this, but the problem seems to come from Firefox. On IExplore, i have a red cross on the graph, don't know why?

[BSOD2600]

No, it's not a problem with your browsers. It's a problem with cacti and the lack of permissions for it to generate the graphs. Please read the install guide in my signature on what needs the correct NTFS rights.

[MPDano]

Hi, I did exactly what the instructions said and I checked and rechecked the NTFS permissions. All is good. Any other suggestions?

[systemslave]

I am having the same problem under Linux. I just read this thread after a search. I will check the permissions and let you know what happens...

Any idea ?

actually i have the same problem and i have searched it out but nothing is done

please help me out people

[BSOD2600]

raktri4u: those fget errors are a sign of incorrect NTFS permissions on rrdtool.exe and/or cmd.exe. make sure the IUSR_ / IIS_WPG accounts have read/execute rights.

[tmc]

having the same problem under linux... don't know how do i have to set the permissions there?

[BSOD2600]

tmc: After reading http://docs.cacti.net/manual:087:4_help.2_debugging post your question in the linux forum.

[matthys]

Yeah .. you sure can say debug, but there are NONE messages.

I got the same results .. no clue where to look.
Access rights are correct and the rrd file is created.

I also checked with "rrdtool info <filename>" and gives me a correct output.
Thought I still do not see any graph or error message

Oeps ... checking Apache I notice an error:
ERROR: the RRD does not contain an RRA matching the chosen CF

This seems to be the problem ... so you not only have to check the Cacti log, but also the websever logs.

[BSOD2600]

matthys: Start a new thread as you have a different issue. Also, the rrdtool messages shouldn't be piped into the web server log, so there is another configuration issue with your setup.

[RB1000]

same problem using under win server 2003, no graphs being generated, only titles.
i do think i have permission problem, read your note, but couldn't find ways to "grant Modify rights "....

any advice would be appreciated

[BSOD2600]

Same as the others users... start you own thread as it's likely a different issue. What graphs dont work? What does graph debugging output spit out? The net-snmp / linux graphs won't work on a Windows system.
