4080.0. "Question for DECmcc engineers" by CSC32::W_MCGAW () Thu Nov 12 1992 17:24

    
     
    Hi,
    
    This is mainly directed at the engineers for DECmcc.  I have a customer
    that is having problems with SNMP alarm rules that stop evaluating. 
    THe rule still says it is enabled and running but the time of last
    evaluation stops getting updated and the rule appears to be stuck. 
    This customer is also having problems graphing live data in much the
    same way.  The man in the graph is in the running position but the
    graph stops being updated.
    
    This customer is using TGV Multinet ip and when he questioned them,
    they asked if we are using read or write ASTs in DECmcc.  What can I
    tell him?

    Thanks,
    Walt

4080.1SNMP AM question for DECmcc engineersYAHEY::BOSEThu Nov 12 1992 17:495
	We have seen similar problems where Alarms and SNMP AM hangs with
	TGV's Multinet software. This is currently under investigtion.

	/rb
4080.2I am aware of the TGV problems.CX3PT3::SHOTO::W_MCGAWFri Nov 13 1992 10:546
Yes, I know.  I have CLD'd the customer in question for both an alarm
rule problem and also graphing of SNMP entities that appears to just
suspend even though the man in the graph box is still in the running
state.

4080.3More information on the TGV problem from the customerCX3PT1::SHOTO::W_MCGAWMon Nov 16 1992 16:12166
Hi,

This is an extract from a workunit the customer sent to me concerning
the alarm rule and graph problems with TGV Multinet IP transport.

I thought this might be helpful and if there is anything you would like 
to have the customer try, please let me know.

Walt

Subj:   RE: MCC 1.2 graphing and private MIB woes

    System KUHUB is a VAX 9000-210 running VMS V5.5-1.
    (HW Ver=00B00000000000040E84116E, SID=0E84116E, XSID=00000101)

Walt (DEC) and Bruce (TGV)

I ran a second DECterm session on the workstation that runs MCC 1.2
and used TGV/Multinet's tcpdump to watch snmp output.

I used CMU's snmp package for VMS (converted by TGV) to issue some snmp
commands and watched the packets get displayed by tcpdump just fine.

Then I went into MCC and typed

show snmp midnet-gw.cc.ukans.edu proteon xface peth, via port 4, in domain
midnet

and saw NO snmp packets issued, yet a few seconds later I got the
attribute not getable window-full

(In line mode I see)

MCC> show snmp midnet-gw.cc.ukans.edu proteon xface peth, via port 4,-
_MCC> in domain midnet
Using default ALL IDENTIFIERS

It was gratifying to see one of my snmp alarms poll a few minutes later.

So it looks as though MCC is not issuing one of the commands to look into
the Proteon private MIB!

	The "peth" child entity does not have any identifier attributes.
	So the above command does not return any attribute values, nor
	does it send out any SNMP requests. The only attributes present for
	the child entity are counter attributes. So the above command with
	"all counters" will give a different result.

	Question about graphing. Can the user do a SHOW operation for the
	attributes he is trying to graph?

4080.5The problem is Proteon's mib.YAHEY::BOSEThu Nov 19 1992 16:1622
	Walt,
		I've finally figured out what the problem is. After talking
	with some other folks having the same problem, it has become apparent
	that the "peth" object is actually a columnar object with instances.
	However, the Proteon mib does not define it as a table object. So,
	there is a major mismatch between what the mib says and what the
	agent knows.

		To make the situation even worse, there are a number of other
	tables implemented in the agent, which are not defined as tables in
	the mib. As such, the Proteon mib is more or less useless. One of the
	requirements that DECmcc imposes on mibs is that they be conformant
	with RFC 1212 (Concise Mib Formats). Proteon's mib does not conform
	to RFC 1212, and hence is unusable by DECmcc. (I know we did ship it
	with our kit, but at that time we were under the impression that the
	Proteon agent did not implement any table objects).

		The only option is to obtain an RFC 1212 compliant mib from
	Proteon and load it into MCC. 

	Rahul.
4080.6response to .4 and .5CX3PT1::SHOTO::W_MCGAWFri Nov 20 1992 13:349
    Hi Rahul,
    
    Thank's for the reply onthe mib problem.  The graphing issue that
    was mentioned in an earlier note, is of an intermittent nature.
    The graph does start out properly but then stops graphing.  I thought
    it was very similar to the SNMP alarm rule problem with the TGV
    multinet IP transport.

4080.7Stack Size?RACER::daveAhh, but fortunately, I have the key to escape reality.Sat Nov 21 1992 16:125
One of The "Multinet" problems has been tracked to a lack of stack
space in the am.  Bump the stack size and you may find the problem
will go away.  The release notes I just saw said to double it from 100 to 200,
but I would be willing to go out on a limb and say that sounds like
overkill with no testing.
4080.8YAHEY::BOSEWed Nov 25 1992 11:5813
	Walt,

		I think we have found the solution to the alarms and
	graph hang problem. The fix will be in 1.3 (which is going to
	field test soon).

		As for the Proteon mib problem, we intend to work with
	Proteon regarding this and come up with a solution. Please convey
	this message to your customer so that he may rest easy.

	Rahul.
 
4080.9Belated thank youCX3PT2::SHOTO::W_MCGAWFri Jan 22 1993 12:049
    Hi, sorry I took so long to respond...
    
    As for reply .7, the stack size had been increased as the release notes
    point out but that didn't have any effect.
    
    As for .8, thanks Rahul!  I will follow up with the customer on both
    counts.
