Graphs from different hosts look equal

[ricardoainati]

Hi,
I'm having a problem to collect remote data using cacti (version 0.86). The data in the graphs from different hosts (localhost and other host) look very similar. I've tried to use SNMP - Generic OID template for the other host with a random OID number and it got equal to the localhost graph. I've followed the instructions in the manual (chapter 13), like Data source type = GAUGE, Maximum Value = 300 (the common values are near 80) and a random OID.
Maybe I'm missing some configuration?

By the way, I get a "CMDPHP: Poller[0] Host[4] DS[28] WARNING: Result from SNMP not valid. Partial Result:" in debug mode.

You should have seen another message right above the one you posted. In this message, you'll see the OID that was used. Is this the correct OID? What is return, when you try to snmpwalk this OID from cli? Please post your findings

Ok, here's a part of the logfile in the debug mode:

When I try the following in the client:
snmpwalk -v 2c -c xxxxxxxx server.c3sl.ufpr.br 2.3.4.3.2.1

I get the message:

joint-iso-ccitt.3.4.3.2.1 = No more variables left in this MIB View (It is past the end of the MIB tree)

Maybe my OID is not correct? (I actually don't have much experience about OIDs)

Yes, now you've got it! You'll have to find out the correct OID. Try this from cli. If and only if this returns some numbers, you may enter this OID into your data template. What data are you currently looking for? Maybe someone already found the OID?

Well, I used the command:

snmpwalk -On -v 2c -c public chimay number1

And the answer was:

number1 = OID: number2

Or the answer wasn't a number, for example:

number1 = Timeticks: (10) 0:00:00.10


I put some "number2" as the SNMP OIDs and a "number1" too. I tried:

snmpwalk -On -v 2c -c public chimay SystemNumUsers

And the answer, wich I also put, was:

.1.3.6.1.2.1.25.1.5 = No more variables left in this MIB View (It is past the end of the MIB tree)

I waited for some time and the results were blank graphs (Current: 0.00, Average: 0.00, Maximum: 0.00 OR Current: nan, Average: nan, Maximum: nan ).

Also I have in the debug mode a strange "U" as the output:

10/10/2005 10:30:03 AM - CMDPHP: Poller[0] Host[4] DS[32] SNMP: v1:client , dsname: snmp_oid, oid: .1.3.6.1.2.1.31, output: U
10/10/2005 10:30:03 AM - CMDPHP: Poller[0] Host[4] DS[32] WARNING: Result from SNMP not valid. Partial Result:

I think I still didn't find the correct OIDs. I already took a look at the forum and didn't find any information that fit. I need to graph as many data as possible.

*How do I get directly the OIDs from CPU usage or number of users (and the others avaiable)? By the way, with the command executed in the host:

snmpwalk -c public -v 1 localhost

I get the following:
