Generate and Monitor Interconnect traffic

Guys
Does anyone has scripts to generate and monitor interconnect traffic? I am trying to test my interconnect on 4 node RAC (10gR2)
Any help?
Thanks in advance
PG

See if this helps....we use the below script to monitor the interconnect traffic.
select b1.inst_id,
b2.value "GCS CR BLOCKS RECEIVED",
b1.value "GCS CR BLOCK RECEIVE TIME",
((b1.value / b2.value) * 10) "AVG CR BLOCK RECEIVE TIME (ms)"
from gv$sysstat b1,
gv$sysstat b2
where b1.name = 'global cache cr block receive time' and
b2.name = 'global cache cr blocks received' and
b1.inst_id = b2.inst_id

Control and monitoring of traffic lights

i am a student and new to graphical programming.i am using labview 6.1 to monitor and control a system of traffic lights from a central location.my problem is geting the lights to go on and off.

You asked the same question here and the answer is still the same. Provide some details on what exactly you're attempting to do and what specifically is the problem. That means details on what kind of hardware you're using to interface to the lights, any error codes being generated, etc. Posting your program would help as well.

Monitoring traffic between UCS fabric extenders and fabric interconnect?

What is the best way to monitor the traffic between UCS fabric extenders (chassis) and fabric interconnect? Specifically I am looking for parameters to keep an eye on to determine when we may need to move from 2 links per fabric extender to 4 to handle greater IO needs.
Thanks.
- Klaus

One way you could monitor usage is by looking at the interface stats just as you would for any switch uplink.
Connect to the Cluster CLI
connect NXOS
Look at the input/output rate of your Server Uplink interfaces.
In my example I'm using fixed ports 1 through 4 on my FI's connecting to the IOM of the Chassis.
UCS-A(nxos)# show int eth1/1-4 | include rate
30 seconds input rate 17114328 bits/sec, 1089 packets/sec
30 seconds output rate 8777736 bits/sec, 693 packets/sec
    input rate 5.07 Mbps, 198 pps; output rate 1.03 Mbps, 99 pps
30 seconds input rate 2376 bits/sec, 0 packets/sec
30 seconds output rate 1584 bits/sec, 2 packets/sec
    input rate 1.58 Kbps, 0 pps; output rate 1.58 Kbps, 3 pps
30 seconds input rate 2376 bits/sec, 0 packets/sec
30 seconds output rate 31680 bits/sec, 20 packets/sec
    input rate 1.58 Kbps, 0 pps; output rate 30.89 Kbps, 18 pps
30 seconds input rate 2376 bits/sec, 0 packets/sec
30 seconds output rate 1584 bits/sec, 1 packets/sec
    input rate 1.58 Kbps, 0 pps; output rate 1.58 Kbps, 3 pps
If you notice your two links pushing near 10G consistently, it might be time to add another 2 link.
Other than this you can use SNMP to log the stats and look based on daily/weekly/monthly usage.

IPv4/ IPV6 Traffic Discrimination and Monitoring

Hi Guys
I would appreciate a lot your experiences and best practices about operating and monitoring dual stack networks in Service Provider environments. Currently we're working in a 6VPE model for Internet customers in order to provide dual stack services, but we are looking for a way that allows us discriminate and monitor both the IPv4 and IPv6 traffic separately.
Does anyone could to share his experiences, how did they were addressed?
What kind of monitoring tools have you used?
What did you do in order to guarantee a reliable monitoring strategy?
I will appreciate your support a lot.
Marcelo

Hi Russell,
I'm in the process of writing a program to do this as I've not seen anything that provides this function available.
For your wired network you should have an inventory of assets containing at least MAC addresses and the user who owns the device.
On your wireless networks you will probably be using SLAAC and I guess you must be using 802.1x in which case you will be able to identify users to MAC addresses.
Essentially you need to periodically gather (less than the age timer) the IPv6 neighbour table from your core switches (or any edge etc, if it routes), this will give you the GUA and ULA against the MAC address. If you using an type of authentication parse those logs for usernames and MAC addresses.
Stir it all together in a database and you should have timestamp, IPv6 address, MAC and user .
cheers,
Seb.

Oracle oleDB generates lots of network traffic than Microsoft Oledb

Hi,
When calling the same stored proc. that returns a ref cursor, Oracle Oledb (1.34 MB) generates alot of network traffic than Microsoft Oledb (0.06 MB). The statistic is gathered using Windows 2000 Network Monitoring tools.
Calling the same stored proc. that returns a ref cursor
Oracle OleDB Microsoft Oledb
Byte Received: 1408026 (1.34 M) 71032 (0.06 M)
Byte Sent: 306468 (0.29M) 69914 ( 0.067M)
Frame: 1263 414
Network Utilization: 6%-14% 1%-3%
Anyone know why is this case?
Joe

When working with ADO and VB6, I looked at the database server with SQL Trace and found that each dynamic SQL statement was parsed twice per execution. REF CURSORs certainly require several network round-trips in order to retrieve schema information for the dataset to be created. This behaviour probably increases network load.
Unfortunately, I have not found any description of Oracle's OLEDB implementation. Hopefully, things will get better with the new, native OleDb data adapter.

Previous post:
multiple parsing of SELECTs O/S : N/A POST: REPLY (W/QUOTE)
Author : Armin Type : N/A
Date : Apr 7, 2001 12:51 PT
System: OLEDB provider 8.1.7, server 8.1.7.
Our VB code dynamically assembles SELECT statements and fetches recordsets with ADO function Recordset::Open. SQL TRACE shows that those SELECTs are parsed twice per execution. SELECTs embedded in stored procedures are parsed only once during the SP's life time (but then the stored procedure call itself is parsed once per execution).
Parsing twice per execution consumes a lot of CPU. REF Cursors might reduce parsing but cause additional network roundtrips.
How could I reduce the parse count?

Aggregates, VLAN's, Jumbo-Frames and cluster interconnect opinions

Hi All,
I'm reviewing my options for a new cluster configuration and would like the opinions of people with more expertise than myself out there.
What I have in mind as follows:
2 x X4170 servers with 8 x NIC's in each.
On each 4170 I was going to configure 2 aggregates with 3 nics in each aggregate as follows
igb0 device in aggr1
igb1 device in aggr1
igb2 device in aggr1
igb3 stand-alone device for iSCSI network
e1000g0 device in aggr2
e1000g1 device in aggr2
e1000g2 device in aggr3
e1000g3 stand-alone device of iSCSI network
Now, on top of these aggregates, I was planning on creating VLAN interfaces which will allow me to connect to our two "public" network segments and for the cluster heartbeat network.
I was then going to configure the vlan's in an IPMP group for failover. I know there are some questions around that configuration in the sense that IPMP will not detect a nic failure if a NIC goes offline in the aggregate, but I could monitor that in a different manner.
At this point, my questions are:
[1] Are vlan's, on top of aggregates, supported withing Solaris Cluster? I've not seen anything in the documentation to mention that it is, or is not for that matter. I see that vlan's are supported, inluding support for cluster interconnects over vlan's.
Now with the standalone interface I want to enable jumbo frames, but I've noticed that the igb.conf file has a global setting for all nic ports, whereas I can enable it for a single nic port in the e1000g.conf kernel driver. My questions are as follows:
[2] What is the general feeling with mixing mtu sizes on the same lan/vlan? Ive seen some comments that this is not a good idea, and some say that it doesnt cause a problem.
[3] If the underlying nic, igb0-2 (aggr1) for example, has 9k mtu enabled, I can force the mtu size (1500) for "normal" networks on the vlan interfaces pointing to my "public" network and cluster interconnect vlan. Does anyone have experience of this causing any issues?
Thanks in advance for all comments/suggestions.

For 1) the question is really "Do I need to enable Jumbo Frames if I don't want to use them (neither public nore private network)" - the answer is no.
For 2) each cluster needs to have its own seperate set of VLANs.

Performance analysis and monitoring of a Forteapplication

Hello,
It would be good if one could do some performance analysis and monitoring of
a Forte application at production time.
By performance analysis I mean measure the time some selected methods take
to return. In a CS application such a method would be some selected method
of a key remote service representative of the application's activity.
One would like to mesure the min, max, average time, and also give a
threshhold which when reached will automatically generate an alarm or some
pre-defined processing.
The most powerful way would be to use a SNMP application through a Forte -
SNMP gateway. (see the G. Puterbaugh paper "Building a Forte-SNMP gateway"
in the 96' Forte Forum proceedings).
But before going that far some simple means accessible through EConsole
would already be great.
A collegue of mine when to that Forum and reported that Puterbaugh said that
such an agent is currently missing, but that its implementation is not
difficult.
I looked at all the agents and their instruments. I came to the following
conclusions :
1) instrumented data are available at the granularity level of a partition,
not at a smaller granularity. For example, the DistObjectMgr agent gives you
very useful information : the number of events (sent/received) and the
number of (remote) methods (called/invoked), but this for the entire
partition. Thus it prevents making tuned observations (unless you partition
in a special way your application to put in a dedicated partition the thing
you want to observe and only this thing).
2) there is no instrumented data related to processing time.
This leads me to the point that no information observed by the standard
agents help me figuring out my performances. Thus I have to add at
development time some lines of code to the methods I potentially want to
observe later at production time to generate the appropriate information a
custom agent will then display (process) with the appropriate instruments.
Does someone share this position ?
Has someone implemented such an agent and assotiated means ?
PS: I will probably implement my own one if no other way around.

I Phone generates huge amount of traffic on its own

Hi there,
I have a serious Problem with one of my IPhones. It started to generate about 2GB of Traffic within a short period of time without me doing anything. All apps closed. It exceede my included traffic and now the provider claims about 1500 EUR / 2000 USD. Provider is not cooperative. Phone locked.
Is there any chance to find out which app, process etc caused that traffic? Is there some kind of log in the iphone? Any hint for clarification are welcome
email download was set to manual. Push notifications on for facebook and whatsup messanger.
Thanks

Hi,
the traffic was generated in my homecountry, so no big cost factors for the provider. Thats maybe why the motivation for solving the issue is minimal from the side of the provider as the 1500 EUR are near 100% profit for them.
The provider is not able to tell me in which period it was generated. In the system they only see besides minor accesses with 20 to 30 MB one big access with about 2GB at once. It was the second day of the new invoicing period, so maximal 2 days but i guess it was even shorter some hours or minutes as the phone is connected to WLAN at home and was not outside of that WLAN for a longer period of time.
For the hint with the notifications: i can not imagine that they produce 2GB in normal usage. I have a secound IPhone with excact the same notifications on and it produced 50 MB in the same period of time.
It seems it was a malfunction of the phone or one app. As there are no logs in the phone the cooperation from the provider is needed, but to be honest they act like I am a criminal. Is there anyone at apple that can force the provider to be cooperative?
I know now at least one case that has exactly the same phenomen and also a very nice claim from the provider.

How to monitor network traffic on an IP alias?

Does anybody happen to know how I can monitor the traffic on an IP alias on say igb0:1 using iftop or something similar? iftop (pcap, I guess is the issue here) doesn't seem to cope with IP aliases.
Cheers

After fiddling around a bit with this issue I decided that it was time to embrace dladm/ipadm a bit more and exchange these old-style virtual NICs with new ones. So I dumped the old igbx:y VNICs and created new ones by issuing:
dladm create-vnic -l igb0 vnic0
followed by:
ipadm create-ip; ipadm create-addr…
Now, I can monitor these new vnics using if top just fine.

RAC - Interconnect traffic

In the client place the architecture team wants to implement a a node RAC cluster on Sun Solaris on Oracle 10g. But in order to minimize the interconnect traffic they want applications to connect only to one node and the other node will provide fail over capability.
Though this can be achieved with less complexity thru physical standby, theoretically if in a 2 node RAC cluster if we just use one node will it eliminate interconnect traffic?
I guess that there will not be any requests from the second node for blocks held by the first node so no transfer of blocks over interconnect will take place. But still the second node has to know about the blocks held by the first node in order to recover in case the first node crashes(cache fusion?). Right?
TIA
RadKrish

just my 0.02 cents on this .. Why would you want to invest in a High Availability Solution ( RAC ) and attempt to achieve Disaster Recovery ( Failover ) through it ..
Why would you want to minimize the Interconnect traffic in the first place .. A decent Switch plus Gigabit Ethernet / Cat5 cables is all you need for the Interconnect and its known to work well with most types of RAC Setup's ..
With Dynamic Resource Remastering , mastership of blocks across the active nodes get distributed based on access patterns .. so with your kind of setup , almost all the blocks would be mastered on Node:1 after a period of sustained activity .. Further Instance recovery happens using information from the Redo Log Thread of the crashed Node so it should not affect Interconnect traffic ..

Is there anyway to monitor network traffic on the newer Time Capsules, similar to the SNMP monitoring previously?

Is there anyway to monitor network traffic on the newer Time Capsules, similar to the SNMP monitoring previously?

Can I use a real router and still have the Time Capsule for backups etc?
Yes, that is what Bridge Mode is for. Just connect the Time Capsule to a LAN <--> Ethernet port on your "main" router.

SA540 - Monitor Web Traffic (How to)?

Just as the title reads, I'm looking for a way to monitor what traffic is going through my SA540. Looking for what websites are being accessed.
Not sure how to do this. Can anyone assist?
Thanks in advance!

I looked into OPENDNS several months ago and seems like it was kinda expensive for commercial usage. It wasn't an option.
I was looking at the Status/Reports section of my 540 and it sounds like it gives the top 10 websites visited. Does this sound correct?
Of course Content Filtering must be turned on. I assume turning on Content Filtering does nothing until allowed or blocked URL data is present?

PCI-4461 - Generate and Record Tone

Hello,
I am trying to play a tone (1K for Example) and record the tone using a microphone. I am using a PCI-4461 to generate and record the tone. I managed to make a somewhat functional program but there are some issues I would like to clear up:
1) I had to make a start and check time function to determine if the tone plays and is recorded for the appropriate amount of time. If I remove the while loop the tone does not play. I tried using the DAQmx wait until done function but it does not seem to make a difference. Is there anyway I can play and record the tone without monitoring the time?
2) The recorded waveform always has a delay which seems dependent upon the sample rate. Ex: 10000 Samples/Sec results in 83 sample delay, 20000 Samp/Sec results in 114 sample delay. I read in some other articles that samples are stored in the buffer and that reading 60ish samples before the actual measurement would clear up the problem. I tried reading samples before the tone is generated but the delay is still present. Currently I am using post processing to remove the delay, is there anyway to only record the tone that is played. Am I triggering the read properly?
Let me know if I should post the VI. Also incase anyone is familiar with acoustics how do I convert a waveform of Voltage vs time to dBV/Pa
Thanks,
E

Hi Plexonite,
The first thing that comes to mind is Pre-trigger Acquisition which could help you retrieve missing data. Further details about this can be found under:

Let us know if this helps you move forward.

Monitoring interface traffic

I'm using a solution to monitor the traffic passing through the interface
SWCORE connecting with my router.
The Linux machine (sniff) has two interfaces (eth0 and eth1)
Etho (manages the machine) connected to the interface to another interface g1/18
(Sniff) connected in g1/27.
Add the following command:
monitor session 2 source interface Gi1/48
monitor session 2 destination interface Gi1/27
But I don't capture nothing.
I show monitor out following:
Session 2
Type : Local Session
Source Ports :
Both : Gi1/48
Destination Ports : Gi1/27
Encapsulation : Native
Ingress : Disabled
Learning : Disabled
Do what doing wrong? Help me??

try this "monitor session 2 source interface Gi1/48 ?"
Doesn't if show an option to span ingoing, outgoing or both traffic directions?
I think you need both
Do you see traffic on the spanport Gi1/27 if you do a "show interface Gi1/27" ?
The counters should go up
The interface Eth0 should be in promiscuous mode to capture the traffic other then for its own mac address or broad/multicast
Cheers,
Michel

Monitoring VLAN traffic

I moved from 2500 series routers to a switched network using a Catalyst 3750 and 3560 switches over the course of the last year. In my routed network I used MRTG to monitor traffic on my interfaces. In my switched network environment I have not been able to find a free or low cost tool that will monitor VLAN traffic. Any suggestions?

I have the same problem and found these links that provided answers:
http://forums.cacti.net/about29656.html&highlight=
http://www.experts-exchange.com/Hardware/Networking_Hardware/Switches/Q_23738165.html
Vlans on 3560s, 3750s and 3550s do not show stats. The packets are forwarded with the ASIC chips and do not cross the CPU for actual processing. To actually see the traffic you will need to turn off CEF, which decrases the performance significantly (not recommended, see links above).
