Which snmp data source type is needed?

[Frodoger]

Hello,

i want to collect data from my Microsoft SQL Server:
snmpwalk shows for physical Page reads:

Code: Select all

snmpwalk -v2c 172.xxx.xxx.xxx -c xxxxxxx .1.3.6.1.4.1.311.1.4.1.1.2.1.4
SNMPv2-SMI::enterprises.311.1.4.1.1.2.1.4.11.82.90.45.90.45.83.81.76.45.48.49 = Counter32: 1767025336

What is the correct snmp Data Source Type for that?
All i get with my tests is an 0 in the graphs.
Can i use the standard Generic SNMP OID templates for values like that?

I use cacti 8.6j under debian linux
The poller is cactid.

Looks like the correct one would be a counter. Of course this depends on how you want the data displayed, too. Counter shows change over time, where as Gauge will keep showing the same value.

i have used gauge and counter in 2 seperate datasources.
after them i have used both data sources in a generic oid graph.
but both graphs shows only 0.

i have checked and both rrd where updated.

Follow this guide http://docs.cacti.net/node/283 why you're getting zero.

Are you sure cacti is collecting data which has been incremented?

thanx BSOD2600.

What did you mean? I think i dont understand the question.

i have give .1.3.6.1.4.1.311.1.4.1.1.2.1.4 as OID to the datasource.
A test with getif and these OID from my pc works
A test with snmpwalk from the cacti host works also.

The datasource debug says:

The debug from the graph says:

RRDTool Says:

OK

And yes i will check and use the tutorial again.

So since you apparently followed that guide, what data is cacti returning each polling cycle for that snmp query?
