Please check e.g. whether crond, mysqld are running
R.

mysql is running.
crontab -u cacti -e :

Code: Select all

*/5 * * * * php /var/www/cacti/poller.php > /dev/null 2>&1

normally cacti log will tell all info. since reboot the server it stoped.

Code: Select all

03/03/2011 03:25:32 PM - AUTH LOGIN: User 'admin' Authenticated 

nothing else after that.

I double checked. run the follow command

Code: Select all

service httpd restart
service mysqld restart
service snmpd restart

it still same......

check if its the snmp graphs that have stopped or the script server ones.
check cacti's logs.
try an snmpwalk on the OIDs that have stopped to graph.

Your checks did NOT make sure that crond is running. And check e.g. /var/log/cron for expected entries

The first one is wrong, the second is ok. So you have two cron entries; I suppose in different files
