For cases where the bad value is lower than the good value, you need to
threshold in a negative direction, which Netview cannot do - as you have
seen.
The workaround for this is to define a mib expression which is your mib
variable
multiplied by  -1. Now you can set the threshold at  -200, and the rearm
arm at -250
or something like that. To do this, edit /usr/OV/conf/mibExpr.conf and add
an
expression like:

Neg_Reliability \
"Reliability from (some.mib.variable * -1"  \
       1.3.6.1.4.1.x.y.z  -1 *

Read about it in the header of that file.
Stop/start snmpCollect to get the file re-read, and check
/usr/OV/log/snmpCol.trace
for syntax or typing errors in that file. Now when you go to add the
collection, switch
from MIB Variable to Expression and select yours off the list.

Cordially,

Hi,

I may be wrong to put my query, I will put it again.
The Reliability is 100 % if the counter value is 255, If it gets degraded
it goes below 255. While if I had to set the threshold I have option only
setting > (greater than), and not < (less than).

I guess I need to set the Absolute value check to < 200, to trigger
threshold action. and rearm value to Absolute <= 225

As I had set the threshold > 85 % as I mentioned it will trigger mail for
all healthy links as they are greater than 85% at the time of data
collection.

Can U advice how can I achieve this.

Regards,
Santosh

   Wouldn't it be easier (or perhaps more logical) to fix the reliability
   problem with the circuit? Sounds like the threshold works great!

   Pardon me, but It sounds as if NetView is doing exactly what you told it
   to
   do. You are the one who decided how to do this, were you not?  It was
   your
   decision to set the thresholds where they are and your decision to send
   e-mail every time the threshold was exceeded.   It sounds like you are
   now
   saying, "Well, perhaps I shouldn't have made the e-mail decisions
   because
   this thing is broken too often."   If you don't like the result, then it
   is
   up to you to design a better way to handle it.

   You could send the e-mail, not right from the trap, but from an Action
   node
   in  ruleset which uses a Threshold to control how often the e-mail is
   sent.
   This is a common use for a ruleset.  If you just use  Event
   Stream(block)
   --> Trap Settings  --> Threshold --> Action (e-mail script)   then you
   can
   run this out of ESE.automation withoiut a problem.

   Or you could adjust the threshold levels, raising the arm level and
   lowering the disarm level so that it doesn't fire so often, so that your
   e-mails are only sent when it has really recovered and then gone
   critical
   again.  The data you collect via snmpCollect is unaffected and will
   still
   be stored regardless of where you sent the monitoring threshold.  So
   you
   could stop sending e-mail altogether and just start saving the data for
   analysis when someone is ready to look at it.

   Hi,

   I need to set this reliability threshold as there is a desperate
   requirement to monitor the reliability of the link. Can U please reply
   for
   this ASAP.

   Santosh

      Hi,

      I have NV6.0.1 on AIX 4.3.3

      I had enabled data collection with threshold check exceeding 85 %
   with
      Rearm of 50% for ifReliability, configured a trap to generate Mail in
      case of threshold reached.

      It is observed that very large No. of mails are generated for this
      collection.

      How can I restrict the same or use the ruleset to put threshold on
   the #
      of mails.

      Regards,
      Santosh
