[mrtg] Re: MRTG 2.8.12: Monitoring more than 2 variables

[Stieers, Ken]

If you saw more than two it wasn't MRTG.

MRTG only does 2.  You can turn on WithPeaks, and that gets you 2 more
lines, but they're maxes pulled from the same 2 data sets.

If it really was 3 data sets, it was probably RRDTOOL, not MRTG.

Subject: [mrtg] MRTG 2.8.12: Monitoring more than 2 variables



I have seen this on one of the sites listed in the MRTG site map, where more
than 2 SNMP variables are being graphed.

Every time I try to do this I get an error. I am using the
OID&OID:community at device  syntax. But when I try to do
OID&OID&OID:community at device I get the error.


The error I get is a SNMP noSuchName error. If I am asking for the following
OIDs:

1.3.6.1.2.1.2.2.1.10
1.3.6.1.2.1.2.2.1.12
1.3.6.1.2.1.2.2.1.18

In the following syntax:
1.3.6.1.2.1.2.2.1.10.2&1.3.6.1.2.1.2.2.1.12.2&1.3.6.1.2.1.2.2.1.18.2:public@
deviceaddress

(I append an interface number to the end of each of course)

I get the following error:

SNMP Error:
Received SNMP response with error code
    error status: noSuchName
    index 2 (OID: 1.3.6.1.2.1.2.2.1.12.2.3.6.1.2.1.2.2.1.18.2)

eviceaddress". I tried multiple times!


Is there a way to graph more than 2 variables, and if so, how?
