SNMP working but doesent display graphs

prxbl · Post by **prxbl** » Wed Nov 28, 2007 7:07 pm

Hello, i have used cacti before and never had this problem, after i installed snmp and cacti on my debian i waited for about 20-30 mins and when i checked to see if graphs apear there was nothing.

i think snmp is working ok when i execute
snmpwalk localhost -c public -v1
i get the folowing:

Hi

are you sure the poller is running ?

Can you run it once by hand ?

prxbl · Post by **prxbl** » Thu Nov 29, 2007 7:18 pm

/usr/share/cacti/site/poller.php >/dev/null 2>/var/log/cacti/poller-error.log
and when i tried to Run it manuly it gave me the folowing error:
Output from command /usr/share/cacti/site/poller.php >/dev/null 2>/var/log/cacti/poller-error.log ..

No output generated

Can you use the "ucd/net SNMP" host template instead ?

prxbl · Post by **prxbl** » Fri Nov 30, 2007 4:41 am

i switched to "ucd/net snmp host" with no result, the graphs are still empty

fmangeant · Post by **fmangeant** » Fri Nov 30, 2007 4:41 am

Can you run the poller once in DEBUG mode ?

prxbl · Post by **prxbl** » Fri Nov 30, 2007 4:44 am

Oops... Your RRDtool files were created "in the future", or your server time has changed. Either delete them, or wait 1196657907 - 1196418006 = 239901 seconds

You should install a NTP client on your Cacti server.

its true i did change the system time because it was wrong, what can i do to delete the RRDtool files, where can i find them ?
