Questions:
----------
. What is the total number of alarms that can be set on DECmcc?
(This question might have been asked before, but my search did
not find any!)
. I understood that it depends on the environment.
But some guidelines are needed as to what DECmcc can and can
not do.
For example, our customer has a VAX4000, with 64 Meg memory, and
wants to set up 500 alarms, with 2 minutes polling intervals!
. If "500 polls, every 2 minutes" is not acceptable, (speaking of
DECmcc limitation only - not worrying about traffic on the network!)
what is acceptable?
Details:
--------
We have a large Digital customer who has purchased DECmcc to
manage their network of 70% LAT traffic. They have about 500
terminals servers.
They have purchased DECmcc to become more pro-active, and their
main concern is reachability. They want to increase their internal
customer satisfaction by getting to the problem before their
customers calls them, as they get dropped by LAT.
Beside the amount of traffic generated on the network being an
issue when creating so many alarms, we need some data as to what
DECmcc can and can not do. And some guidelines on resources it takes.
And in general, when service turn around time is critical, what is
the proper way of checking for reachability of a large number of
devices such as Terminal Servers, Ethernet Stations or SNMP devices?
Thanks,
Mahnaz

| 2689.1 | Alarms in v1.2 supports Global Wildcards | MOLAR::ROBERTS | Keith Roberts - DECmcc Toolkit Team | Fri Apr 03 1992 22:04 | 25 |
Mahnaz,
I cannot say for sure how many rules you can run for v1.2, but I would
guess that 100 to 150 would be the limit for your VAX4000.
But, if you are planning on running rules which are all the same except
for the entity which needs to be polled -- DECmcc v1.2 Alarms supports
global wildcards.
You can write a single rule which will poll all of the specified entity
class in a specific domain, that is:
(node4 * maximum address > 50, at every 00:30:00)
This rule, created in a specific domain, will poll each node4 entity in
the domain .. repeating every 30 minutes.
Be aware however, the entities are polled serially - one after the
other, and not in parallel. So this type of rule would need a
reasonable polling interval like 30 minutes because in a domain with a
lot of entities it may take a while to communicate to every entity.
Hope this helps.

| 2689.3 | Alarms in v1.2 doesn't support Global Wildcards | NEXUS6::BERNECICH | Fri Apr 10 1992 11:40 | 51 | |
Hi,
I've installed mcc ft 1.2.15 on my vs3100/76 vms 5-4.2. 32mb.
I try to write a single rule which will poll all of the specified
in a domain entity but the creation fail.
$ Manage/Enter
DECmcc (X1.2.15)
CREATE MCC 0 ALARMS RULE Rech_state_on -
EXPRESSION = (NODE4 * state = on , AT EVERY 00:10:00) ,-
PROCEDURE = MCC_COMMON:MCC_ALARMS_LOG_ALARM.COM ,-
EXCEPTION HANDLER = MCC_COMMON:MCC_ALARMS_LOG_EXCEPTION.COM ,-
CATEGORY = " Node Reachable " ,-
DESCRIPTION = " Node Reachable " ,-
PARAMETER = " NODE_ALARMS.LOG " ,-
PERCEIVED SEVERITY = warning ,-
IN DOMAIN = milan
MCC 0 ALARMS RULE Rech_state_on
AT 10-APR-1992 16:29:07
Valid entity specification not found in alarm expression.
-- But for one entity

You are trying what we call a "Global entity wildcard". That is not supported in X1.2.15, but will be supported in EFT Update. -- Erik | |||||
