data collection problem

Post by utkualp »

Hi eveyone,

Now i have another problem. I'm using 0.8.8a v of cacti. I've just added all my backbone cisco routers as device. After that created some graphs like CPU or interface in/out bits. But i have interruptions in most of my graphs. One of the example is below. It is the CPU graph one of my backbone routers. You can see that i cannot have any data since ~2 hours.

But when i try to get the data with snmpwalk, i receive the correct data and do not any any timeout or error from the router

As i said before, i have this problem for more than 80% of my graphs. What might be the problem? Do i have to change the version of cacti i have installed? What would you prefer for troubleshooting?

Regards,
Utku

mysql error 1062 is duplicate entry. Do you have two pollers running at once?

Per http://docs.cacti.net/manual:088:4_help.2_debugging does rrdtool fetch <rrd file> AVERAGE show recent data? RRD File Ownership correct?

it is not about file ownership "i think", because i have also datas in the rrd file (as you can see in the graph).
i dont see any error about snmp polling. there is an error only about writing the data to rrd file.

As i said my problem is to not be able to write the snmp results to rrd files.
in cacti.log file i see all the missing values of the graphs. But that is happening only for some graphs.

ok, new clue regarding to gandalf's last post
i see 2 pollers running same time

Feb 10 00:05:01 Hostname CROND[13576]: (cactiuser) CMD (/usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1)
Feb 10 00:05:01 Hostname CROND[13575]: (root) CMD (/usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1)

but in crontab, i cannot find the poller process for cactiuser

Code: Select all

[root@Hostname/]# crontab -l
*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1
#15 */6 * * * sh /backup.sh > /dev/null 2>&1

Code: Select all

[cactiuser@Hostname~]$ crontab -l
no crontab for cactiuser
What should i do?

*/5 * * * * cactiuser /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1
