No Graphs missing rrd files

[andyb28]

Please can someone help me with this problem, I have been searching for a solution all day.

I have installed cacti following a good guide from this forum and everything is working except the graphs.

When I try to view the graph, the log shows

RRDTool Says:

ERROR: opening '/usr/share/cacti/rra/foundry_traffic_in_36.rrd': No such file or directory

I have tried various solutions to this problem, I know for sure that the SNMP data is correct and working fine on the device side of Cacti.

Below I have pasted some information that may assist.

Hi andyb28. Have you solved your problem? I'm missing some .rrd files also...

[andyb28]

Hi Everyone,

My problems have now been fixed, I made some mistakes on the cron job, one of my friends took a look at it today and pointed out my error.

Now the cron job is running, the files are being produced and the graphs work.

Nice Can you post the cron line and where did you put it (crontab, etc..)? Thanks.

[andyb28]

Hi noisebleed,

Here you go.

[root@iX ~]# crontab -l
*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

I think my confusion came from the yum version installs in /usr/share/cacti

Thanks andyb28.

Which user is running that cron entry? root? I've tryed with apache and root and the results are the same.

I've some graphs but newer graphs aren't created and I don't know how to force that.

The docs say thar rrdtool puts and entry to create graphs on the next poller run but no new rrd file is created.

Permissions are ok on /log and /rra. Don't know where to turn now.

I'm checking cacti.log and cron-poller.log (see below) and everythin seems ok...

Btw, my cron is on /etc/crontab:

Code: Select all

#*/5 * * * *    apache  /usr/bin/php /usr/share/webapps/cacti/0.8.7b-r2/htdocs/poller.php > /dev/null 2>&1
*/5 * * * *     root    /usr/bin/php -q /usr/share/webapps/cacti/0.8.7b-r2/htdocs/poller.php --force --debug >> /usr/share/webapps/cacti/0.8.7b-r2/htdocs/log/cron-poller.log 2>&1

Suggestions?
