RE: [nv-l] Ping is falling behind

[Peter Raig <praig@us.ibm.com>]

I'm Curious:since your holding your
node downs for 14 minutes, are you still doing 3 retries before considering
an IP to be down? 

Also, what's the delay on your name
resolution like? you got thousands of those to do in a 5 minute poll cycle
right?

Thank for the replies.

Betreff: [nv-l] Ping is falling behind
 

NetView 7.1.4 AIX 5.2

* I am using the script below to check the ping status of NetView and I
am seeing numbers around 30,000 at times. I am having problems with
nodes going down for reboots and coming back up within about 5 minutes
and I am getting node down events. I have a timer rule in place that
says if I get a node down event hold it for 14 minutes. If I get a node
up event drop the node down. If the 14 minutes expires and no node up
event came in send the node down event.

* Well the nodes are coming back well before the 14 minutes and we are
still getting the node down. I believe that NetView being behind in
polling is causing this. Are there any suggestions as to fixing the
polling falling behind issue?

* Within the last year SNMP was enabled on our workstation machines
resulting in about 7000 new objects being discovered by NetView. Since
they have the same OID as the Windows servers they are brought into
discovery. I want to restrict them from being discovered by name. They
all have a common set of characters in the name. The naming convention
is ***wu******  or  ***WU******. The same number of characters are used.
If I read the documentation in the seed file correctly I could use this
login correct?

!???wu??????
!???WU?????

Am I interpreting the question marks correctly from the documentation?

 #      Negative Entries
#          e.g.        !10.1.1.2                  Specific entry
#                      !10.*.1.1-100              Ranges using * or -
#                      !router*.tivoli.com        Wildcards using * and
?(single char)
#                      !@oid 1.3.6.1.4.1.9.*      Wildcards as final
char using *
#                                                 (Note space after the
prefix "@oid ")
#                      !@oid 0                    This entry will
filter out all
#                                                 non-SNMP supported
devices

* I have unmanaged as many devices as I can that aren't being monitored
at the moment and have restricted discovery to several OID's. My DNS in
on another machine but on the same local subnet. Has anyone here written
a script to test the speed of resolution from DNS?
 

Here is the result of the ovobjprint -S command:

ovobjprint -S
Number of objects defined in the database: 93939

Total number of fields defined in the database is: 306.
