Actually, looks like others have done this with script queries. So I guess it doesn't really matter now. :)

I was hoping I could've done it this way but no matter, it's the end result that counts!

Be prepared to find a decrease of performance of a magnitude between scripts and pure snmp. May be more or even less. I would bet on "more"

Hello all, having issues getting this to work in my particular case. I am trying to get a table of information from a load balancer and graph the active connections and transfer rate information in cacti. I tried following the how to the best I could, the images are mostly gone and its possible I missed a setting somewhere in there if it was checked in the image but no mention of it was made in the text.

Anyway the other issue that exists is there is no nice and easy index like in the example. None of the table entries specify a real index number. I'll post the table/walk and my xml below and what I have done to try to get it to work.

I then created a data template with the following configuration options:

Data Template - Name: kemp - rsConns
Data Source - Name: (checked) kemp_rsConns
Data Input Method - Get SNMP Data (Indexed)
Associated RRA's - (All Selected)
Step - 300
Data Source Active - (Checked)

Data Source Item - Internal Data Source Name - rsConns
Minimum Value/Maximum Value - 0
Data Source Type - Counter
Heartbeat - 600

Custom Data - Index Type (checked)
Custom Data - Index Value (checked)
Custom Data - Output Type ID (checked)

I then made a simple graph, called it kemp - rsConns and added a line1 graph type, average consolidation function and linked it to the data source rsConns I defined above.

I proceded to add the graph template to the data query. I did not however put anything in suggested values.

And now I am at a point where I create the graph, but nothing is ever put into a RRD file. If I go to Data Sources and turn on debug mode I get the following:

Code: Select all

/usr/bin/rrdtool create \
/var/www/html/rra/kemp_lb1_rsconns_546.rrd \
--step 300  \
DS:rsConns:COUNTER:600:0:U \
RRA:AVERAGE:0.5:1:10080 \
RRA:AVERAGE:0.5:1:25920 \
RRA:AVERAGE:0.5:6:9000 \

RRA:MAX:0.5:1:10080 \
RRA:MAX:0.5:1:25920 \
RRA:MAX:0.5:6:9000 \
RRA:MAX:0.5:24:2250 \
RRA:MAX:0.5:288:797 \
RRA:LAST:0.5:1:10080 \
RRA:LAST:0.5:1:25920 \
RRA:LAST:0.5:6:9000 \
RRA:LAST:0.5:24:2250 \
RRA:LAST:0.5:288:797 \
Any ideas what could be causing the problem? If I set the value in the XML to input it does get picked up by Cacti (granted you can't graph it but I knew that would happen). Any help would be appreciated.

Please try using .1.3.6.1.4.1.12196.12.2.1.1 as an <oid_index>. It will span from 1 to 14.
This howto is now abandoned and continued at http://docs.cacti.net. But you may open a new thread at any time to ask your questions

How do I filter certain values in snmp walk using snmp query? I have following output:

Code: Select all

IF-MIB::ifType.1 = INTEGER: softwareLoopback(24)
IF-MIB::ifType.2 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.3 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.4 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.5 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.6 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.7 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.8 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.9 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.10 = INTEGER: atm(37)
IF-MIB::ifType.11 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.12 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.13 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.14 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.15 = INTEGER: ethernetCsmacd(6)
If I need only atm(37) interfaces what that filter could be applied in snmp query?[/code]

Re: [HOWTO] From snmptable to Graphs (Data Query walkthrough

Post by in2deep »

Thanks for the excellent walkthrough. I got the Diskio graph to work, but the problem is I have no idea what i'm graphing. The device name do not make any sense to me. I have a bunch of ram0-10+, sda1+, etc.... device names to graph but I have no clue what they are associated with e.g /x/home (a nsf mount point). Is there a command to find out the device names = some path names? Really appreciate if you can answer my question. Thanks in advance.

The command "mount" should help

Thanks for the reply. I tried but none of the output strings match the snmp device names output. Other suggestions are welcome.

Try iostat, then mount.

Example on Solaris:

Code: Select all

% iostat -x
                  extended device statistics
device       r/s    w/s   kr/s   kw/s wait actv  svc_t  %w  %b

Re: [HOWTO] From snmptable to Graphs (Data Query walkthrough)

Hello,
Thank you very much for this guide. The problem is that I'm sutck in the 1st step. Indeed I'm not used to use snmp ...
So my cacti server is on centos 7. I just install it and right now I'm trying to connect to a device (VSAT) that is on iDirect. I hope I'm following the good guide for that.
So my problem is that when I'm trying to run : snmptable -c <community> -v 1 <host> HOST-RESOURCES-MIB::hrStorageTable.
When I use the Ip of the server I've this result :
End of MIB
HOST-RESOURCES-MIB::hrStorageTable: No entries
When I use the Ip of the VSAT I've this result :
Timeout: No Response from xxx.xx.x.x.
Honnestly it's been 2 days I'm looking to find solutions and nothing is working.
(snmp is enable and is running, I don't have the right to connect to the VSAT so I can't check anything on it.)
I hope someone will be able to help me.

By the way I'm an intern at the moment so I'm doing my best to learn.
Best regards,
Top
