Cacti graph not working

[puspharaj]

Hi There,

I've been started to using Cacti for 3 months and found my ucd/net CPU usage and ucd/net Memory graph is working with my two server and not working for several servers.

The working servers are fine with CPU and Memory usage grpahs , On the not working side i have seen nan values in my graph

Some one please pin point where could be the problem

thanks

Mr.Gandalf,

Please help me out i dont have a clue what went wrong. These servers are my productions servers and i need it to get it done by this week for my critical application launch monitoring.

My cacti log indicates nothing went wrong.

How do i check it manually is that the graph working fine or not ?

Thanks
Puspharaj

I fear that you're using the localhost templates. Please use the ucd/net-snmp templates for remote hosts

In case snmpget does work, Cacti won't work either. Please solve the SNMP issue (e.g. by configuring the target client) before retrying

Gandalf,

The snmp failiure is only for the particular OID not for the entire client machine. I got few other grpahs working fine on that machine
From my server i issue this

snmpwalk -v 1 c secret remote_ip .1.3.6.1.4.1.2021.4.14.0

It returns END of MIB or something

thanks

Again, that is an SNMP error. The SNMPGET must return a valid number to be graphed. This is NOT a cacti issue
