how use one Data template with multiple data source items ?

[ehaha]

i have a Huawei S8512 switch ,it has 4 slots . i want to use cacti for collecting cpu status by snmp.

[root@cat ~]# snmpwalk -c cacti -v 2c -m ALL *.*.*.* 1.3.6.1.4.1.2011.6.1.1
SNMPv2-SMI::enterprises.2011.6.1.1.1.2.0 = Gauge32: 6
SNMPv2-SMI::enterprises.2011.6.1.1.1.2.1 = Gauge32: 6
SNMPv2-SMI::enterprises.2011.6.1.1.1.2.2 = Gauge32: 5
SNMPv2-SMI::enterprises.2011.6.1.1.1.2.4 = Gauge32: 4
SNMPv2-SMI::enterprises.2011.6.1.1.1.2.6 = Gauge32: 10
SNMPv2-SMI::enterprises.2011.6.1.1.1.3.0 = Gauge32: 6
SNMPv2-SMI::enterprises.2011.6.1.1.1.3.1 = Gauge32: 6
SNMPv2-SMI::enterprises.2011.6.1.1.1.3.2 = Gauge32: 5
SNMPv2-SMI::enterprises.2011.6.1.1.1.3.4 = Gauge32: 5
SNMPv2-SMI::enterprises.2011.6.1.1.1.3.6 = Gauge32: 11
SNMPv2-SMI::enterprises.2011.6.1.1.1.4.0 = Gauge32: 6
SNMPv2-SMI::enterprises.2011.6.1.1.1.4.1 = Gauge32: 6
SNMPv2-SMI::enterprises.2011.6.1.1.1.4.2 = Gauge32: 5
SNMPv2-SMI::enterprises.2011.6.1.1.1.4.4 = Gauge32: 5
SNMPv2-SMI::enterprises.2011.6.1.1.1.4.6 = Gauge32: 11

The issue is this. Under 'Data Templates' I create, for the sake of
simplicity, 2 data sources. I then set the 'Internal Data Source Name'
of each 'Data Source Item'. These values stay as set.

I then go down into the 'Custom Data' section and for ds1 add the
following OID to the 'OID' textfield and hit save:
.1.3.6.1.4.1.2011.6.1.1.1.2.0

Then for ds2 I add the following OID to the 'OID' textfield and hit save:
.1.3.6.1.4.1.2011.6.1.1.1.2.1

When I go look at ds1 it now has ds2's OID and if I change it back to
the correct OID ds2 then has ds1's OID after hitting save.

My question is this. How do I get cacti to poll multiple (6) different
OIDs and place then in one rrd?

Should I change my 'Data Input Method' from 'Get SNMP Data'? If yes? what?

Thanks.

i had read Cacti 0.8.6 HowTo , but i don't know how do it now!

http://docs.cacti.net/node/80

there is use one Data template with one data source items .


it is not i want !

Sorry, I assumed that this is an SNMP Index Query issue. And this one is fully explained some chapters later

Could you please provide the direct link to the docs section where I can find out how to use multiple (2 or more) data source items with different unique non-indexed OIDs per data source? In RRD terms, I'd like to save several different OIDs in a single RRD file and then graph them on a single graph.
I looked through many forum posts and all available docs on docs.cacti.net and still can't find an authoritative answer whether it is possible or not and how to do it. It seems to be a basic feature in MRTG and I can't find the same feature in cacti. Please help!

Two different solutions are possible:
1) Create a single Data Template for each OID required. non-indexed SNMP OIDs today require a single Data Template per OID.
Then, create a Graph Template that combines those numbers of OIDs required for your task.
This is the most performant approach
2) Create a script that uses cacti_snmp_get to get any number of OIDs you want. Spit them out in a single line as given at http://docs.cacti.net/node/203
This requires a songle Data Template only and again a Graph Template combining those data source of the (single) Data Template.
Running scripts calling SNMP is less performant

Thanks for your reply.
Do I understand correctly, that in current cacti version the only way to have multiple OIDs stored in a single RRD file is to use a script with multiple output fields? If this is correct, is there a plan to implement an option to use different unique OIDs per each data source item in a single data template?

[gandalf]

Your understanding is quite correct.
IMHO, such a feature request does NOT exist. But I only know about feature request of last 30 months. There's a chance that I missed sth. So please add your request

Well, not true. A Data Template can have as many Data Souces as you want as long as each has it's own OID in the space provided. The data input method could then be SNMP Get.

Hello TheWitness,

i don't understand what you mean with:

..has it's own OID in the space provided.

I need a data template with more than one datasources and an own oid for each datasource.

And this is not possible to create right now with cacti 0.8.7e.

I hope you could help me to resolv this.

Sarah

Hi
I am trying to achieve exactly this. Is this possible in the current version of cacti? For some reason my rrds dont get created. When i manually create my rrd, it does not run the 'Get SNMP' command. In my cacti.log, I don't see any updates to the rrd nor do I see any snmp queries.
Thanks,
munira
