rrd not generating graphs [Solved]

Code: Select all

RRDTool Command:

/usr/local/bin/rrdtool graph - \

GPRINT:cdefi:AVERAGE:"Average\:%8.2lf %s"  \
GPRINT:cdefi:MAX:"Maximum\:%8.2lf %s\n" 

RRDTool Says:

ERROR: opening '/usr/local/share/cacti/rra/freebsd_hdd_free_21.rrd': No such file or directory

For each graph...same error...any clue?



Edit: Problem solved.

Update info:

Code: Select all

Data Source Debug

/usr/local/bin/rrdtool create \
/usr/local/share/cacti/rra/freebsd_hdd_free_23.rrd \
--step 300  \
DS:hdd_free:GAUGE:600:0:U \
DS:hdd_used:GAUGE:600:0:U \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \

If i run manually this command (as cactiuser)...the graph appear...but no update later


EDIT: add comment about user

Edit: Problem with poller time solved.

Please check your crontabs for multiple occurences of the poller
- /etc/crontab
- /etc/cron.d/cacti
- crontabs of user root and cactiuser
THERE MUST BE ONLY ONE CRONTAB ENTRY

The, please check, that the user running the poller has write access to the ./rra directory

OK...sorry for the delay.Thx for the answer:

- Double check, only one entry in crontab

The, please check, that the user running the poller has write access to the ./rra directory

yap:

drwxr-xr-x 2 cactinoc cactinoc 512B Dec 31 1969 log
drwxr-xr-x 2 cactinoc cactinoc 512B May 7 12:50 rra

log and rra...same permissions, log update ok, but no graph yet.



The details about version's and variables:

Apache/2.0.55 (FreeBSD) PHP/5.1.2
cacti: 0.8.6h
cactid: 0.8.6f
MySQL: 5

Any other clue?

Thanks in advance.



PS: Sorry for my english, i'm speak spanish.

Aditional data:

When i check the device page on cacti admin, my test device, the status appears down (SNMP ERROR)...could be this the problem? I'm not interested in activate snmpd for my local device...is stricted necessary this option?
BTW, the data queries for the graph not require snmp:

1) Linux - Memory Usage


Edit: Info about query.

[Marcelo]

OK....adding a host with SNMP enabled...the rrd's appear.
it's correct this?

[jmadrid2]

You dont necessarily need to use snmpd. You can also use netsaint statd so you dont have to enable SNMP.

Correct. And there are more methods. Not using SNMP: please clear the community string of the device and it will not be tested for SNMP availability

Ok, the tip of clear community works like a charm.
Thx a lot!
This problem solved.


PS: This tip is on the manual?
