Re: [Devmon] MDS9000 fibre channel switch

Hi Geoff & Buchan,

A break through this morning, finally. Thanks to your encouraging mail, I
discovered that running devmon interactively and in verbose mode is very
infomative if things do no work out right.

I do use the TABLE:-directive but it never showed up in Xymon. The table
output however, was made the way I wanted it. It showed however binary
values. Yoohoo!

Alarming on (, 9�,��,, |,�, )
Alarming on (|,x,l,�, , )
Alarming on (,,,,@&,)
Alarming on ()
<table border=1 cellpadding=5>
<tr><td>connUnitPortStatCountError</td><td>InvalidCRC</td></tr>
<tr><td></td><td></td></tr>
<tr><td> 9�</td><td></td></tr>
<tr><td>��</td><td></td></tr>
<tr><td></td><td></td></tr>
<tr><td> |</td><td></td></tr>
<tr><td>�</td><td></td></tr>
<tr><td> </td><td></td></tr>
<tr><td>|</td><td></td></tr>
<tr><td>x</td><td></td></tr>
<tr><td>l</td><td></td></tr>
<tr><td>�</td><td></td></tr>
<tr><td> </td><td></td></tr>
<tr><td> </td><td></td></tr>
<tr><td></td><td></td></tr>
<tr><td></td><td></td></tr>
<tr><td></td><td></td></tr>
<tr><td></td><td></td></tr>
<tr><td>@&</td><td> </td></tr>
<tr><td></td><td></td></tr>
<tr><td></td><td></td></tr>
</table>

Devmon version 0.3.1-beta1 running on xxxx

So since the output is hexadecimal (I think that is what snmpwalk tells me,
below), I could simply convert this to integers using the CONVERT-transform
option. Now the table can be seen in Xymon, but unfortunately the output is
not correct.

So I must be making another mistake here :-(

the oids-file:

connUnitPortStatCountInvalidCRC : .1.3.6.1.3.94.4.5.1.40 : branch
connUnitPortStatCountError      : .1.3.6.1.3.94.4.5.1.3  : branch

the transforms-file:

IntconnUnitPortStatCountInvalidCRC : CONVERT:
{connUnitPortStatCountInvalidCRC} hex
IntconnUnitPortStatCountError      : CONVERT: {connUnitPortStatCountError}
hex

the message-file:

TABLE:
connUnitPortStatCountError|InvalidCRC
{IntconnUnitPortStatCountError}|{IntconnUnitPortStatCountInvalidCRC}

Do you have any hints/suggestions?
