No rrd files

[pacon007]

Hello all.

I have install cacti on a Linux Debian box. Al has gone fine, no errors while installing but when I tried to analyze graph appears this code:

ERROR: opening '/usr/share/cacti/site/rra/localhost_mem_buffers_3.rrd': No such file or directory

When I check rra directory I see no rrd file. I ran poller, no error and even I don't see any log on cacti.log.

ANY HELP????????????

Usually, this is due to "Host Downed Detection" seeing the device as unreachable (e.g. ICMP is blocked"). You may want to change global settings at "Settings"

Hi gandalf,

I don't understand that. If the system is on "Host Downed Detection", why Cacti does not create a rrd file?

[gandalf]

Cacti will not perform any polling on systems that it supposes to be down. But downed host detection may be wrong (e.g. if ICMP is blocked)

Hello again,

Thanks Gandalf but I don't think that is the problem. As you can see, on the code I copy earlier, the graph I want to check is a local host graph.
I do have ping access to localhost.

Code: Select all

ntop01:~# ping localhost
PING localhost.localdomain (127.0.0.1) 56(84) bytes of data.
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=1 ttl=64 time=0.027 ms
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=2 ttl=64 time=0.032 ms
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=3 ttl=64 time=0.034 ms

64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=6 ttl=64 time=0.033 ms

Any other idea... I think that the problem might be on some permission.
This is how it looks my cacti directory.

Any idea???

Other big problem I am facing is that I don't see nothing on cacti.log
This is how my log file looks like:
cactiuser@ntop01:/usr/share/cacti/site/log$ more cacti.log
cactiuser@ntop01:/usr/share/cacti/site/log$

And this is how I configure Cacti:

Please login as cactiuser and run poller.php manually. Wathc ut for errors. Find more help at the second link of my signature
