5839.0. "SNMP Alarm woes" by ADO75A::BOUCHER (Reece Boucher) Sat Jan 22 1994 19:02
Greetings,
I am having some problems with SNMP IP reachability alarms.
I am running DECmcc V1.3.0 on a VMS V5.5-2 VAXstation 4000 Model 60. I am
currently monitoring approximately 70 cisco routers and need the following to
occur:
Poll for IP reachability every 60 sec. If a node is unreachable, send a
mail message DECMCC::SYSTEM, which gets directed directly to Target HOTline
(Help desk application). Therefore, IP Poller no good.
Poll for IP reachability every 60 sec. If reachability up, send
notification with severity clear to IMPM. No mail sent. (used to clear the icon
on the map only).
What is actually happening is that I am getting a lot of alarms firing saying
that entities are unreachable, when in fact they are. This is causing a number
of problems WRT Target HOTline. It appears that a low value of ICMP timeout or
retry is being applied, even though I have increased them in the process that
enables the alarms.
Attached are copies of the alarms rules that are enabled, as well as the log
file that is created by the alarms process.
Q: Is there any way I can use the IP reachability Poller to fire an alarm ? I
need to be able to send a MAIL message on a poll failure.
Q: Is there a better way of achieving what I need to do ?
Your help is greatly appreciated.

When you get an alarm for reachability down, can you immediately
issue a "SHOW SNMP xxxx ALL STATUS" and tell us the result.

| 5839.2 | option: 2nd poll in script | CTHQ::WOODCOCK | Skiing's 1st Human Groomer | Mon Jan 24 1994 10:52 | 15 |
| Greetings,
Assuming you get the poller as robust as it can be and you are still having
problems I'd recommend an implementation modification.
Within the script POLL THE DEVICE AGAIN if you can. I did this using ncp
because of a similar problem as you describe however I have not tried this
with snmp. You could take two approaches. I simply did an "ncp tell x sho exec"
an captured the $STATUS. If successful this means the node is not really down
and don't send mail (in you're case don't send to TARGET). You might be able
to use the same technique by issueing "mcc show snmp x ipreachability, to file
=x.txt". Then search x.txt for "down" before sending to TARGET.
just a thought,
brad...

| Rahul,
Showing the status of the SNMP device directly after an IP reachability
Down normally shows IP Reachability=UP.
Brad,
I take it the way you are suggesting is to use the Data Collector.
This would work, but doesn't it go against the intention of the IP
Poller ?
Thanks for the replies.

Actually no, not quite what I was suggesting. This may actually go against
the IP Poller but I'm not sure because I've never used it. Anyway, what we do
is write a simple alarm rule, enable it, and if something alarms down then in
the script we poll the device again. By doing this we double check whether the
device is really down, the network glitched, or the router was too busy, or
etc.
Alarm rule expression something like exp=(snmp * ipreachability=down)
procedure=node_down.com
enable rule
logic in node_down.com
- get snmp device name
- poll it again through the script
$ mcc show snmp <device> ipreachability,to file=x.txt
$ sea x.txt down
$ if $status .ne. %x0000001 then node_status="down"
$ if node_status .eqs. "down"
$ then
$ send mail
$ etc, etc...
$ endif
The above stuff is not exact by any means, it will also not be fast. What it
does do is double check to make sure the device is down before sending mail
or creating a TARGET ticket which is the major hassle we are faced with.
cheers,
brad...

RE .3
Reece,
This probably means that the alarm encountered an exception.
Can you check the contents of the alarms notification to confirm
that ?
Rahul.
|
| 5839.6 | No exceptions encountered | ADO75A::BOUCHER | Reece Boucher | Wed Jan 26 1994 18:50 | 13 |
| Rahul,
No exceptions were logged in mcc_notification.log.
There are just normal IP reachability Up and IP Reachability DOWN error
conditions reported.
The difference between the two however, can be as much as 10 minutes.
FYI.
Reece...
