wrong values are graphed

[acharrier]

I am trying to graph data from our APC Air Removal Units.

When I use a MIB browser, I can see the OIDs and that the return the correct value. When I use those OID numbers in the generic SNMP template, nothing appears on the graph and the numeric values wrong and never change over time.

This same method worked for me to graph data from Weather Duck appliance, so wondering why this is failing. Any ideas?

OID data pulled from MIB browser is below.

OID: .1.3.6.1.4.1.318.1.1.14.4.1.1.8.1.1
Value: 360
Type: Integer

OID: .1.3.6.1.4.1.318.1.1.14.4.1.1.8.1.2
Value: 357
Type: Integer

OID: .1.3.6.1.4.1.318.1.1.14.4.1.1.8.1.3
Value: 368
Type: Integer

OID: .1.3.6.1.4.1.318.1.1.14.4.1.1.8.1.4
Value: 356
Type: Integer

OID: .1.3.6.1.4.1.318.1.1.14.4.1.1.7.1.1
Value: 1886
Type: Integer

OID: .1.3.6.1.4.1.318.1.1.14.4.1.1.7.1.2
Value: 1862
Type: Integer

OID: .1.3.6.1.4.1.318.1.1.14.4.1.1.7.1.3
Value: 1913
Type: Integer

OID: .1.3.6.1.4.1.318.1.1.14.4.1.1.7.1.4
Value: 1858
Type: Integer

Hey I'm saving a very similar problem as you are (i think).

Have you found anything that has helped your situation?

Thanks!

What I've found is that the OID for any one fan cannot be queried but that using the parent OID will return the value for all 4 fans. Do an SNMPWalk against this value .1.3.6.1.4.1.318.1.1.14.4.1.1.8.1 and I think you'll see what I mean.

I've not looped back to this problem recently, so it's really a matter of learning how to graph all 4 values at one time now.

Ok, I've got a really ugly perl script written up to get the fan rpm (and CFM also if you want that) and graph it.

Here is the perl script (If someone can clean it up a bit, that would rock. i'm not the best with perl)

and attached are the Templates.

Code: Select all

#!/usr/bin/perl
unlink '/tmp/fanrpm';
unlink '/tmp/fanrpm1';
open(SN, "snmpwalk -v 1 -c public 172.16.240.201 .1.3.6.1.4.1.318.1.1.14.4.1.1.8 |") || die "failed: $!\n";
open(FD, '>>/tmp/fanrpm');

while(<SN>)
{
chomp;
$value = substr $_, -4;

print FD $value;
}
system "sed 's/ //' /tmp/fanrpm > /tmp/fanrpm1";


close (SN);
close (FD);

open(FD, '/tmp/fanrpm1');
while(<FD>)
{
chomp;
$rpm = $_;
@values = split / /, $rpm;
$i = 0,;
foreach $rpm (@values)
{$i++;
print "Fan$i:$rpm ";
#print "\n";
}
}
close(FD);
