[Devmon] (no subject)

[crankshaft <cra...@oc...>]

Hi,

I'm having trouble pulling the values (mainly temperature) 
from a Sentry CDU power distro unit and storing in a rrd 
file for graphing. I've got two temp sensors plugged in 
(intake and exhaust) but it appears these two sensors use 
the same OID (enterprises.1718.3.2.5.1.6), but the first 
sensor has index / instance? number of 1.1, and the second 
one has 1.2 .
I can get the values to display on the status page of the 
devmon test as a table, and can get them from snmpget. I 
did have them inputting into .rrd and was able to graph 
the data, but whenever the temperature changed it seemed 
to generate another .rrd, the result being multiple graphs 
showing "flatline" dot / dash values of the temps at 22, 
22.5, 23 etc.
Is it possible to simply give the two sensors different 
mnenomics in the template/oids file such as:

intakeTemp :  enterprises.1718.3.2.5.1.6.1.1 : ????????
exhaustTemp :  enterprises.1718.3.2.5.1.6.1.2 : ????????

to use them in the message file to generate the.rrd and if 
so, what do I put in the ???????? section? I've tried 
branch and leaf, but get the 'No snmp data for oid' error 
in devmon.log and devmon-scan.log with branch and 'oid is 
a non-repeater' error with leaf. The docs Transform 
section says something about the INDEX transform but 
doesn't give an example of its usage.

The .rrd generator in templates/message is (off the top of 
my head):

<!-- DEVMON RRD temperature 00
DS:TempValue:temperature(.*):GAUGE:600:0:U
-->

where TempValue is the result of a MATH transform of /10:1 
on tempHumidSensorTempValue (which is 
 enterprises.1718.3.2.5.1.6).

The graph definition is the [temp] one in hobbitgraph.cfg, 
with the .rrd and ds0 substituted with temperature and 
TempValue.


thanks in advance,

Geoff
