How to fetch network utilization...

I am doing a project related to network monitoring
so i need to know the the utilization of network
resource,
we can say the incoming and outgoing traffic of a
particular network interface card, or the percentage
utilization of the capablity of that network card..
Is there any API related to that..so i can use that...
i shall be really thankfull

If the devices in question have SNMP agents running, you could find an SNMP library and query the appropriate OIDs.
Whatever approach you take will involve a fair amount of research and work. There's no getUtilization(host, interface) method in the core API. You might be able to find a 3rd party library, but that would defeat the purpose of your homework.

Wireless Network Utilization

Relatively simple question, I am just having a tough time figuring out analyze the data.
Anyway...
We use the Tamograph Wireless Survey utility and with this utility you are able to perform passive, predictive and active surveys.
With the passive\predictive you can calculate the SIR (Signal to Interference ratio) expected. You can change the "average network utilization" as a variable to formulate the SIR values.
I am having a tough time correlating our controller\AP data with that value.
When I look at the AP's I see Load Statistics. Would I be concerned with TX, RX or Channel Utilization or ALL when it comes to 802.11 interference ratios?

From the application support documentation:
"This visualization shows the signal-to-interference ratio (SIR) measured in dB. SIR is a measure to quantify by how much the signal level of an AP (interfered AP) exceeds the interference level. The interfering signal is the signal being transmitted by other APs (interfering APs) that may or may not belong to your WLAN and that use the same or one of the adjacent 802.11 channels. In low SIR zones, client devices may experience low throughput. SIR is shown for the AP that experiences the worst interference in the given map area among the APs selected for analysis. You can deselect one or several of the selected APs to see SIR values for the APs that experience less interference."
"SIR is best illustrated with an example. Consider an area where the AP signal strength is -50 dBm, and the AP works on channel 1. In the same area, a -70 dBm signal from another AP that works on the same channel can be seen. If WLAN utilization is 100% (i.e., if the APs send radio waves all the time), the SIR value would be 20 dB. However, real-world WLAN utilization is almost never that high, which decreases the interference and increases SIR. If the interfered and interfering APs have the same signal strength, the SIR value would be 0 dB. In classical, non-digital radios, a SIR value of 0 dB makes signal reception impossible, but 802.11 devices use a technology that allows them to operate despite a zero or even negative SIR value, which sounds counterintuitive."
On network Utilization -
"Average network utilization – This setting defines how heavy the interference is from the interfering APs. If the interfering signal strength is high, but the network utilization is low, the interfering AP does not create much interference. A typical office WLAN has a network utilization of between 10% and 25%. Adjust this setting to match the actual value for your WLAN. "
After reading all of this would you say that Channel utilization is the best value to look at on the Cisco WLC that correlates to the "Average Network Utilization"?
I am going to check with the software vendor as well. In the meantime what is a good, expected Channel utilization value? Is there a range?

From my program I can only pass directory , Folder name,System Id,Date only. I don't have time value in my program.
So please tell me how to fetch files without having time stamp value from app. server.
Plz send me exact code.It's urgent.

Do you want to return the file to the user on click of button or something?
Then, use web_show_document with http link which you are speaking about.
Else download the file to client using Webutil.

How to fetch accounting document number from known material document number

Hi,
Using MIGO transaction, by giving mblnr(material document number) as input, I get accounting document number by clicking FI document.I have to add this accounting document number in my report for corresponding known mblnr(material document number) values.
My question is how to fetch the accounting document number present in MIGO to add in my report program.
I used the xblnr(Reference Document Number) which is present both in mkpf and bkpf tables to fetch values.
I extracted xblnr values with known mblnr values from mkpf (Header: Material Document table).
and then extracted belnr(accounting document number) from bkpf (Accounting Document Header table) by using xblnr values.
But the query is running for a long time.
Is there any other method to extract the values in a simpler way.
Kindly advise.
Thanks and Regards,
Sanjeev

I had the values of xblnr and some other fields such as mblnr, budat etc in wi_item table.
I created a new internal table i_xblnr and got down those values.
And then created a new internal table i_belnr and tried to get values of belnr in it.
The code I wrote is given below:
IF not wi_item[] is initial.
loop at wi_item.
   at new xblnr.
    ws_xblnr-xblnr = wi_item-xblnr.
     append ws_xblnr to i_xblnr.
   endat.
endloop.
select belnr xblnr from bkpf into table i_belnr for all entries in i_xblnr where xblnr = i_xblnr-xblnr.
ENDIF.
Kindly look after it.Thank you.
Regards,
Sanjeev

OPEN my_CuRSR FOR
SELECT DISTINCT blah blah blahmy_cursr is what I am returning as OUT param in my SP.Correct. At the point you open the cursor, oracle has not attempted any 'fetch' against the data so it won't know if there is any data or no data. that only occurs when a fetch is attempted.

How to fetch data from different sources into one source (like into Ztable)

hi friends,
As per our client requirements they want to develope an Inventory and an Ontime delivery report in BO on top of Oracle database.
Situation is some thing like they have ECC 6.0.and they want to collect all inventory and ontime delivery data at one place.According to me that could be one Ztable in which we can gather all data.Apart from that they are going to use Data Integrator in which they can directly fetch the data from R/3 system(They dont want to have BI system) and put all data in Oracle DB.On top of ORacle BO person can develop BO reports.
My question is how to fetch all data at one place and what are the tables going to be use.
kindly help me out as its very important project.
Thanks
Abhishek

The following is my standard reply to those who need to get old data from a backup in one account and add it to another account. The method described here may be applied to your case. It would be a bit of a long process, though.
When connected to the account you want to GET data from, Go to Settings>iCloud and turn all data that is syncing with iCloud (contacts, calendars, etc.) to Off.
When prompted choose to keep the data on the iPhone.
After everything is turned off, scroll to the bottom and tap Delete Account. Next, set up a new iCloud account using a different Apple ID and turn iCloud data syncing for contacts, etc. back to On. When prompted, choose Merge. This will upload the data to this new account.
Note that this only affects the "Apple data" like contacts, calendars, reminders, etc. Many third party apps also use iCloud to store data files there. These files may be lost in the process, unless the apps also keep the data locally on the device.
NOTE: Photos in the photo stream (if you use it) will not transfer to the new account. It is advised that you save the photos to a computer before performing the account switch.

hi everyone... can you teach me how i configure networking in my infrastructure..
i am getting confuse that i have 2 phisical server, i don't know to set the netwokring in scvmm. Every best practice, i found in internet is using more than 2 physical server.
i have been tried before with the networking which i want..but it failed...
any one help me please...

This whitepaper should explain the required steps to get this working.
http://gallery.technet.microsoft.com/Hybrid-Cloud-with-NVGRE-aa6e1e9a
The whitepaper will use more than two hyper-v hosts, but you'll get the picture.
You can have 1 host to run your NVGRE VMs, while the other host should be dedicated to run the virtualization gateway VMs.

How to show network status in top toolbar?

how to show network status in top toolbar? Network preferences is there, but network status has disappeared on last reset of Airport Express, but may not be connected. Thanks in advance for practical help

Interestingly, in my experience, using the method described above of unchecking the "Show Connected Servers" box in the Finder Preferences makes no difference in what I can put in the sidebar. I was able to move a sub-folder of a shared disk to the Favorites section of the Finder Sidebar, but nothing else. (i.e. I could not add the shard disk itself to the sidebar – either to the devices, favorites, or any other section, and I could only add a subfolder of the shared disk to the favorites section – not to the devices section or any other section). This was the same whether I had "Show Connected Servers" checked or not.
I'm running OS X Mavericks, and the setup I have is with a previous generation Time Capsule (i.e. the short, square kind that you could buy before the most recent taller variety came out last year), with a LaCie 3 TB USB 3.0 external drive plugged into the USB port of the Time Capsule. I'm then accessing this network drive over WiFi. The differences in what I'm seeing may be due to some change they made in the way Mavericks handles these setups.
I could also just be misunderstanding what you're saying, but I thought I'd add this in case anyone else gets similar results so that they'd know they're not alone. Let me know if I'm missing something here.

How to fetch some certain records at a time

Hi everyone,
I dont know how to fetch some records at a time,
for some reason,there is not enouht memory.so I cant
fethch all the records at a time.
example, every time I only want to fetch 10
records. Does anyone know that?
thanks
Krussi

I think you may be getting setFetchSize(int) and setMaxRows(int) confused. I may have added to the confusion with my breaking out of the loop comment.
setFetchSize(int) gives the driver a hint as to how many rows it should store in memory at a time internally, ie. within the driver. It has no real effect on how you write your program at all. Its only purpose is to limit memory usage by the driver. To limit the rows returned, use setMaxRows.
For example, assume a result set has 20 rows and you use:
rs.setFetchSize(5);
while (rs.next()) {
System.out.println("Rows: " + (++count));
} You still get a count from 1 to 20. However, internally the driver is only holding in memory 5 records at a time, after the 5 returned it will discard those and get the next 5. So instead of holding 20 rows, its only holding 5 at a time. If you change rs.setFetchSize(5) to rs.setMaxRows(5) you will only get a count from 1 to 5, the rest are silently discared and rs.next() returns false.
Check your documentation to see if your driver supports the method. I believe many drivers don't. If not, I believe there is no way around multiple queries. Even if there is no rowid, as long as you order your queries you should be able to start again where you left off.
Disclaimer: Both drivers I commonly use do not implement setFetchSize(int). Someone let me know if I've fudged something here.
Good Luck

How to fetch the messages, line number etc.
By seing docs i wont be able to figure it out.
Can any one send piece of code to fetch the error messages.

If you access the FacesContext you find a method called
