How to draw graph for remote devices?

[michaelhoang]

Hi Everyone,

I am a new user in Cacti.
I'm using Cacti 0.8.8 installed on RHEL 6.5. It is running fine for graph but having some problem while collecting data from Remote server.

When creating graph for remote server, it is drawing exactly the same with the local graph.
From the devices, I have used the Host template is "None" as suggested by the Documentation when we are not sure about the type we should use.

However, it is collecting and drawing the graph using local data hence it is exactly the same as the local graph is.
Can you let me know which I should configure to draw the graph for remote server?
Any suggestion or recommendation is highly appreciate :)

Thank you for your time for my question.
Regards,
Michael

What did you put as the "hostname" for the remote host? Did you put its IP / hostname, or did you put localhost?

Hi Cigamit,
Thank you for your suggestion.

Yah of course...I used IP Address for the host.
It's ping and SNMP checking successfully.

Do I need to configure on the remote server in this situation?
Any other advises are welcome

Thanks and best regards,
Michael

You will need SNMP configured on the remote host, and you will want to make sure you are using the Host MIB graphs and the Data Queries such as 'SNMP - Interface Statistics', instead of the ones for the localhost.

If you scroll down and show a picture of what graph templates / data queries you have assigned to the device, I can help steer you in the right direction.

Thanks cigamit very much for your help.

I have configured the snmp on remote host but not sure if I'm in correct way.
Using snmpwalk -v 1 -c public tcp:localhost:161 command on remote host, i can see the output of the MIBs.

However, it is still drawing the local graph instead of remote server graph.
Please find the screenshot of the device detail below.
Please let me know what I need to do to achieve the remote server data graph.

Thanks and best regards,

Ya, you are using the graphs that are only meant to be used with the local server. Under "Associated Graph Templates", click that drop down and add the ones that start with "Host Mib". Then under the 'Associated Data Queries', select the ones that begin with 'SNMP - '. Then at the top, click the link to 'Create Graphs' and select the graphs you just specified. As another step, you will want to click on 'Data Sources' on the left in the console, and delete the data sources that belong to those other graphs for that host. Be sure to tell it to clean up the associated graphs also when it prompts you.

Oh I got it Remote server will need to use Host mib and SNMP Data query...
I have made the change (delete then re-add the device actually :p) but there is no resource detecting...
Verbose query for "SNMP - Get Mounted Partition" is giving the output as the following:

+ Running data query [8].
+ Found type = '6' [Script Query - Script Server].
+ Found data query XML file at '/usr/share/cacti/resource/script_server/host_disk.xml'
+ XML file parsed ok.

Does that mean SNMP is not configured on remote server?
Thank you for your help in advance

What type of device is it? Does it already have SNMP configured and listening?

that is another RHEL 6.5 server.
net-snmp has been installed, configured and running on that server

From cacti server, i can use the simple snmpwalk query to retrieve the data on that remote side:
[root@### rra]# snmpwalk -v 2c -c public #### .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux ######### ....

[cigamit]

Also, try changing the SNMP version to 2 and see if that helps.

Oh yah Finally, mounted partition are returned to success.
However, it cannot discover anything on the server

I saw the following error while creating graph for Mounted Partition:
No more variables left in this MIB View (It is past the end of the MIB tree)

Also, graph is not drawing for the other as screenshot attached.
Can you suggest how I can proceed on this?

Thank you for your time and your help in advance

You can try to edit /etc/snmp/snmpd.conf and change the 'view all' line to

Code: Select all

view all        included  .1                                      80

then restart snmpd, and requery the data query.

I have made the change, restart snmpd then requery the data.
However, the data is not shown up
I still face the error:
No more variables left in this MIB View (It is past the end of the MIB tree)

Can you post that portion of your snmpd.conf ? Kinda curious what it shows in there vs what I have in Centos.

Yah please find the snmpd.conf as attached.
