1717.0. "Alarm rule to test DECserver accessability?" by KAOFS::BOIVIN (Moi, j'viens du nord!) Fri Oct 25 1991 08:16

Good day,

I'm using TSAM with BMS V1.1 and am trying to find out the syntax
for creating an alarm rule for DECservers (DS500, DS300 and MS300).

I've seen the earlier replies with rules like:

Expression = (TERMINAL_SERVER xxxx software status <> "Normal")

but what I'm looking for is the equivalent rule for the
FCL command TEST TERMINAL_SERVER xxxx, TESTNAME=ACCESS.

Any help is appreciated.

1717.1No capability for TESTTOOK::ORENSTEINFri Oct 25 1991 14:0910
    
    All rules issue a SHOW directive OR a GETEVENT directive to the entity in 
    the rule.  The OCCURS expression will issue the GETEVENT directive and
    all other rule forms will issue a SHOW directive.
    
    Is there an attribute or an event you can watch for?  There is no
    capability to do the TEST directive using an Alarm rule.

1717.2no attributes if server access = unavailableTOOK::CASSIDYLinda, LKG2-2/BB10, DTN 226-7270Fri Oct 25 1991 14:5919
    RE .0
    
    I don't think this is possible.  I don't know that much about alarms,
    so anyone please correct me if I'm wrong - The alarm has to be based on
    some expected value for a specified attribute.  You want to test if the
    terminal server is available.  If the server is not available, you
    can't get any attributes from the server at all, so comparing values is
    not possible.  The only attributes you can get when the server is down
    are the ACCESS attributes, but none of them will help you.

    RE: .1
    
    What happens if you have an alarm issuing a SHOW directive and the
    directive fails?  I assume the alarm does not work at all, right?

    P.S. - Alarms based on TEST results would certainly be useful!
1717.3Well why not *make up* an attribute?TOOK::MCPHERSONi&#039;m only 5 foot one...Fri Oct 25 1991 16:237
You might want to synthesize an attribute like, say, "LAT Reachability" and 
then have that map into some code that does a "test server" sort of thing.

You might want to talk to Dan Carr about what they monkeyed into the SNMP AM 
along those lines...(e.g. IP Reachability -> "ping")

1717.5Exeception procedure will be firedVIDOAN::DOANEIS/Network Consulting Group of the 90&#039;sMon Oct 28 1991 10:508
Hi,

	Re: .2, if the directive (i.e. SHOW) failed, then the exception procedure
	will be fired (if you specified it in your alarm rule).

	Am I correct ?

1717.6Exception is not a very "true" indicatorTOOK::MCPHERSONi&#039;m only 5 foot one...Mon Oct 28 1991 13:415
...of anything except that an exception has occurred.

Your rule may not have been able to evaluate for any number of reasons.
