The "." at the end indicates that the expression should be used for each
instance of the mib with that variable...
So DhcpTest.1 uses 1.3.6.1.4.1.311.1.3.2.1.1.3.1
DhcpTest.2 uses 1.3.6.1.4.1.311.1.3.2.1.1.3.2
Etc..

isn't there a dot too much behind the pdu 1.3.6.1.4.1.311.1.3.2.1.1.3 ?

Hi Matt,
in my opinion this is really a good idea!
I added the mib expression, that in theory should make the trick, but for
some reason I always get back value "100".
This is the expression, that I added:
DhcpTest \
"100 - noAddfree" \
100 .1.3.6.1.4.1.311.1.3.2.1.1.3. -
The snmpCol.trace file doesn´t show any errors or problems. MIB browser
shows correct values for MIB variable "noAddfree".
As a last test I changed the data type of the mib variable (noAddfree) to
"Integer", "gauge", reloaded the dhcp.mib, restarted the snmpCol daemon,
but
this again had not been of help. I´m using Netview 7.1.2 on Solaris.
Any ideas are pretty welcome. Many thanks.

Thorsten,
I don't know if this would be simpler but why not try something like
100 - noAddFree and check for Threshold > 98 (this would imply noAddFree <
2) or something equivalent.

Hi all,
sorry for stressing you all up again, but these are really my first
attempts
in the "snmpCollect / mibExpr.conf" area.
I´m working on DHCP monitoring. Therefore I loaded the DHCP.mib and looked
for a way to monitor the amount of "free DHCP addresses". The MIB variable,
that has to be used here best, is named "noAddFree" (number of free
addresses).
problem 1:
is there really no way to use a "less than" operator for specifying
thresholds? I´m lost. All I can see in Netview is this hardcoded "greater
than" symbol. It would be quite easy to compare MIB variable "noAddFree"
against a threshold using a "less than" operator.
problem 2:
I made some testing with a self-made MIB expression. In theory it returns
the amount of DHCP addresses, that are still free. To be able to use the
hardcoded "greater than" operator, the value of this expression is always
negative.
That is the expression:
DhcpStillFree \
"noAddinUse - (noAddFree + noAddinUse)" \
.1.3.6.1.4.1.311.1.3.2.1.1.2. \
.1.3.6.1.4.1.311.1.3.2.1.1.3. \
.1.3.6.1.4.1.311.1.3.2.1.1.2. + -
snmpCollect is gathering data, but for some reason the values shown are
always equal to "0". On the other hand the MIB browser is showing the
correct values for MIB variables "noAddinUse" and "noAddFree", so I´m
wondering a little. Is it also not allowed to use and display negative
thresholds? Hopefully not!
Who can shine some light on me please. Thanks a lot for all your great help
and support!!! I won´t forget it :o)
We are going with Netview 7.1.2.
