3869.0. "MCC : monitoring more than 300 Internet nodes ?" by ZTOIS1::VISTA (Renato VISTA, SIS Strasbourg, France) Wed Oct 07 1992 08:37

    Hi,
    
    I'm working in a DECmcc/ULTRIX BMS V1.2 environment.
    
    My customer wants to monitor Internet systems (ICMP/ping level).
    
    As he has to monitor more than 300 U*X stations, he has firstly defined
    more than 300 rules, in polling mode, on ipReachability attribute.
    
    Althought the polling interval is not too small (00:06:00 minutes), he
    finds that this way monitoring (and the functional need covered) is
    very weak versus the hardware configuration (DECsystem 5900 +
    DECstation 5000/133) expected to get performances (especially when using 
    Iconic_map).
    
    Asynchronous Traps are not seen as efficient way to monitor
    "internet-end-node" (because of Warm/Coldstart traps are sent when reboot
    is done, and not when break down happens...) ; it is possible when 
    sophisticated SNMP agents can sent enterpriseSpecific traps... (
    which will be completely displayed by DECmcc...V1.3...).
    
    Futhermore, he knows that HP Openview has the ability of monitoring
    ip datagrams in listening mode to determine whether an Internet
    station is talking on the "network" or not. If not, and after given timing
    out, an Internet station is declared as DOWN.
    
    I have no detailed information about such mechanism and I don't know if
    it is really efficient... 
    
    Does anybody have any information about that kind of tools ?
    
    
    Regards

3869.1V1.3 should answer some of your prayers.YAHEY::BOSEWed Oct 07 1992 15:0411
	Renato,
		For DECmcc V1.3 we have planned an ip reachability poller
	which will run as a separate process and channel events to the
	SNMP AM. With notification services set up, this will allow the
	icon colors to change when a node comes up or goes down. We have
	the poller running on a VAXstation 3100 M38 with 20 Mb memory and
	the resources used is minimal. More details regarding the poller
	will be provided later.

	Rahul.
3869.2What about DECstation/ULTRIX platform ?48283::VISTARenato VISTA, SIS Strasbourg, FranceThu Oct 08 1992 11:0516
    
    Hi Rahul,
    
    Thank you for your reply. I think it seems to be an interesting
    solution. 
    
    1) Is there any SNMP poller planned running on a DECstation/ULTRIX/RISC ?
    
    2) Is there any interoperability from SNMP-both ULTRIX & VMS
    based-poller with both DECmcc V1.3 ULTRIX & VMS platforms ?
    
    Regards,
    Renato
    
    
    
3869.3Poller will be both VMS and ULTRIXCHRISB::BRIENENDECmcc LAN and SNMP Stuff...Thu Oct 08 1992 18:5810
RE:

>  1) Is there any SNMP poller planned running on a DECstation/ULTRIX/RISC ?

	The poller will run on both VMS and ULTRIX.

	Not sure what you mean by "interoperable". The first version
	of the poller will not be distributed (i.e. there will be one
	poller per MCC system). We are looking at distribution in a
	subsequent release...
3869.4Wonderful ipReachability news; how about DECnet Phase IV?CUJO::HILLDan Hill-Net.Mgt.-Customer ResidentMon Oct 12 1992 01:185
    This is great news, and something that has been needed all along.  How
    about something for DECnet nodes now?  What about bridges and terminal
    servers?
    
    -Dan
3869.5Definitely needed, but...CHRISB::BRIENENDECmcc LAN and SNMP Stuff...Tue Oct 13 1992 13:3111
Hi Dan,

 We're doing an IP Reachability Poller for V1.3 to gain some experience with
pollers in general (learning about integrating pollers with MCC, performance
gains possible, etc). The IP poller we have now SCREAMS...

 We want to follow up (in a short development cycle release beyond V1.3)
with efficient pollers for other technologies, along with technology
specific Auto Discovery.

3869.6VAXstation 4000 Model 90: Polling and EventsCUJO::HILLDan Hill-Net.Mgt.-Customer ResidentWed Oct 14 1992 02:2729
    I demonstrated DECmcc V1.2 on a VAXstation 4000 Model 90, 80MB memory,
    to two of my customers today.  I was polling 300+ ip nodes & 50+ DECnet
    nodes (5min intervals), 20+ stations (30sec intervals), 30+ bridges
    (5min intervals), and the odd terminal server, while at the same time
    receiving 1200 events generated by 6 nodes in 30 seconds.  I had two
    map windows up along with the Notification Services window.  I had
    roughly 10-15 alarms firing every minute, logging was enabled on most
    of them.  This node was also part of a 19 node cluster, and was serving
    its disks to other cluster members.
    
    The performance of this system was VERY IMPRESSIVE.  I could navigate
    the maps with no problem at all (no noticable pauses).  It was a true
    pleasure.
    
    I can't wait to see what you guys have done with ipReachability
    polling.  The DECnet reachability problem (polling is a customer
    requirement) still needs some serious attention.
    
    DECmcc is really beginning to move forward to become a more useful and
    (dare I say) fun product to manage multi-protocol networks.  My
    customers commented on the multi-protocol capabilities once again today
    as something that is virtually untouchable by other network management
    platforms.  Why don't we advertise this more?
    
    
    Keep up the good work.  Also, try one of our $11,995 base-priced,
    Alpha-Ready, 43 VUP, 33 SPECmark, VAXstation 400 Model 90 workstations
    with a second-generation Ethernet controller (9.5Mbit/sec sustained).
    What a SWEET system.  Try one.  The faster, the better.
