UCCX 8.5.1 SU2 traffic analysis report errors out
Anyone run into this before, I'm not seeing a bug fixed for this issue in SU3 either.
If we have a call center outage or some issue effecting services, one day a month, and try to run the IVR traffic analysis report for the whole month (where one day we had outage) the report for that timeframe fails to run. If we adjust the report begin/end time to end before problem day/hour the report runs fine. Same for after that time to end of the month. We can also run the report for the single day of outage (whole 24 hour period) without problem to which is strange.
Regarding the outage, it is where UCCX services stop for some reason. This is HA WAN setup. The systems were not powered down or shutdown unexpectedly.
Seems it is choking on the data and trying to divde by zero....
We see this in logs,

It is common, in many of the Cisco Express 8.5 environments we have looked at, for the Total Incoming Calls given on a Traffic Analysis report to be a higher number than an Application Report.
The Traffic Analysis Report counts every unique sessionID (unique call) that is inbound (contact type of 1). The Application Reports do a similar thing but qualify (filter) only the records that have an application assigned.
There are simply times where inbound calls have been directed to an "agent" without having an applicaiton assigned.
The best thing the reporting user can do is to run a query on his or her database such as:
select * from ContactCallDetail where contactType=1and startDateTime > '2012-11-16 10:00:00' and startDateTime < '2012-11-16 11:00:00';
Usually when an application is not assigned to the record in the ContactCallDetail table it is because the destination type is equal to 1, which is an 'Agent' instead of a 'route point'.
So if you modify your select statement to filter by destinationType, you can quickly find the records that don't have the application assigned.
Example: select * from ContactCallDetail where contactType = 1 and destinationType = 1 and startDateTime > '2012-11-16 10:00:00 and startDateTime < 2012-11-16 11:00:00';
When you look at these records, you will see the agent that took the call from the destinationID field. The number in that field should match up with the field called 'resourceID' in a table called 'resouce';
Example: select * from resource where resouce=6011; where 6011 was the number you found in the destinationID field.
If there is still confusion about the source of the call - then talk to that agent and find out what is was.
Good Luck and let me know if you need further help.

Traffic analysis report by team / CSQ
Hi Everybody,
Is it possible to show the Traffic analysis report by team / CSQ?
Because I cannot find any param or filter in this report type.
Or I have to use other report type?
Thanks in advance
SamHi Sam
It's possible, certainly - however it would involve creating a custom version of the report.
This would include:
- Developing a customised SQL stored procedure to generate the statistics
- Creating a new Crystal Reports template (for HRC) or CUIC Template for the report in CUIC Premium, and exporting that to UCCX.
Do you have suitable skills in house or a Cisco Partner you can use for this sort of work?

Have any source code can produce a web traffic analysis?
I want to get the source code to produce a web traffic analysis report, for example i input a tomcat's access_log, it can analysis this log file and then output the analysis result in html file format.
I have already found a source code to parsing the IE's log file, but i can't find a source code to parse the tomcat's access_log file.
Have anybody know where can download this source code.......Thank a lot!!!!!I also want to know how to do this........

Hi all,
If I noticed a lot of (incoming&outcoming) traffic in outside interface of ASA. Is there any way to know where is this traffic coming or going to (IP address)?
And if that traffic happened earlier (for example 1 day ago), can I still know the origin or destination IP address?
Please help!!
Thanks in Advance,
OmerThanks Marvin for your reply.
Actually I asked this question because I've seen spiky load in my outside interface which looked suspicious. I was curious to know where it came from.
I used show conn command, but it was only showing the connections in use.
I'm using opennms as monitioring tool, but not sure if it will help in this case.
Any recommendation??
Thanks,

NAM Report Analyze -- Wan Optimization -- Application Performance Analysis Report
Hello,
Transaction Time (Client Exprerience) report does not show optimized traffic. For this graph what we expect is to show side by side the transaction time of optimized and non optimized traffic side by side to give information about the baseline and optimized application performance.
May it be that the optimization should be disabled for some time for the Wan Sites, and after some time manually reenabled in order to compare these values? This should be difficult for large deployments since manually disabling and reenabling for performance analysis time taking task.

SharePoint 2010 Site Web Analytics - Top Pages report not showing complete data
Hi,
I have a custom page in a team site which takes list ID as an argument and shows the relevant data e.g.
../Dashboards/View%20Briefing.aspx?BriefingID=1078
../Dashboards/View%20Briefing.aspx?BriefingID=1079 etc
When i look at the Top Pages report under Site Web Analytics all i can see is data for:
/dashboards/view briefing.aspx
I need stats for individual list items i.e. how many time BreifingID 1078 was viewed etc. Is it possible to achieve this using OOTB reports or can i write a custom report to achieve this? If yes then how...
Any help would be appreciated.
Regards,
KashifYou’re dynamically filtering content on a single page with values on the query string. Your users are still only hitting one page (View%20Briefing.aspx). Analytics only sees that 'View%20Briefing.aspx' is being hit; it won’t record stats for what’s specified
on the query string.
I expect you could pull this data out of your IIS logs using log parser. Some links on this subject:

hello Gurus
I want to do the sizing with the quick sizer from marketplace, but i don t have clearly the terms, please send me info about sizing in BI, the help indicates:
<b>Business Intelligence
SAP NetWeaver Business Intelligence Find information about SAP NetWeaver Business Intelligence at the Service Marketplace -> Business Intelligence, for example information about Performance Tuning.
User Groups Business Planning
Planning 1,
Planning 2,
Planning 3 Definition
The general idea is to define user groups which are determined by the number and size of data records they work with and the types of planning functions they execute. If you are not sure exactly how many data are involved, you can take the proposed values, which are based on internal measurements and customer feedback.
Specifics for User Groups Business Planning
Users
Estimate the highest number of active users per hour. Opposed to other sizing approaches in the Quick Sizer you can arbitrarily include users in a specific group. Normally the user groups reflect the fact that you have power, medium and occasional users (example at "Planning steps per user").
Planning steps per user
Estimate the peak number of planning steps per user and hour.
Example for "Users" and "Planning steps per user"
A user carries out six planning functions, the first three work on the same set of data (5,000 records), the other ones each work on separate set of 600 records. If this sequence is carried out every 20 minutes, we were faced with 18 planning steps per hour and user.
Average number of data records per planning step
A planning step always contains exactly one planning function, for example a formula function. If that planning sequences are used, these cannot be calculated as a planning step, instead the number of planning functions contained must be entered. The average number of data records manipulated by one single planning step has an impact on the CPU time consumed by a user.
Example
In our example we have an average of 2,800 ( = (3 * 5,000 + 3 * 600) / 6) records per planning step.
Note
o The term planning step is often understood from a business view, where it means a total run of a planning area. Here, we take a functional perspective.
o The memory requirement and CPU consumption is estimated on the basis of this data. To determine memory requirements, we assume that there is an average data record length of 1KB.
Maximum data per planning step
Estimate the maximum number of data records manipulated by one single planning step.
Example
As mentioned above the planning functions work through different sets of data. The maximum number is 5,000 per hour and user.
Maximum data per user
Estimate the maximum number of data records a user holds in memory simultaneously. This is needed to estimate the memory consumption of a user.
Example
Take the example mentioned above. If the user doesn't leave the transaction, he holds 6,800 (5,000 + 600 + 600 + 600) records in memory. Please keep in mind, that the set of data is the sum of records read and records created
Comment
Editing/creating data records is achieved by planning functions or manual planning. We do not differentiate between these two types for sizing, as both of them are used to manipulate data records.
We only size "User Groups Business Planning". NetWeaver BI server must be sized separately. However, the sizing result includes the part of NetWeaver BI that is used to deliver the transaction data to "User Groups Business Planning". For sizing the load generated on the NetWeaver BI system by "User Groups Business Planning" we assume that 30% of all executed planning steps access NetWeaver BI. For the remaining 70% of the planning steps we assume that they manipulate data records which have already been read by NetWeaver BI.
BI Users
BI-INFO,
BI-BUSIN.,
BI EXPERT Definition
In NetWeaver BI, we distinguish roughly between user types according to their frequency of activity and the reporting they will normally do.
Active User Type Navigation Steps per Hour This user will predominantly ...
Information Consumer 1 ... view predefined and static reports
Business User 11 ... navigate within reports, do slicing and dicing, but usually hit aggregates
BI Expert 33 and more ... run ad-hoc queries with a high probability of full table scans
A navigation step includes drilling down in the reports and corresponds to nine dialog steps in the SD benchmark. If you don't know the user distribution, a typical ratio in the NetWeaver BI environment is 71% : 26% : 3% (Information Consumer : Business User : BI Expert).
Comment
The system automatically calculates the Java parts which are shown at the result level.
If BI Java is not used, you should add 5 % to the SAPS of the application server.
User Groups Reporting & Analysis
Definition
Collection of a selection of characteristics and key figures (InfoObjects) for the analysis of the data of an InfoProvider. A query always refers exactly to one InfoProvider, whereas you can define as many queries as you like for each InfoProvider.
For sizing purposes we distinguish between three query types which are defined by the load they create in the system.
Report Viewing: Predefined, static, reports using optimal aggregates
OLAP Analysis: Slicing and dicing, navigating in reports, using various aggregates
Data Exploration: Data mining, that is ad-hoc reports with unpredictable navigation paths, access of detail data, full table scans
Any user can do any type of query. However, experience shows a certain activity pattern, as you can see in the table below.
Query Type Report Viewing OLAP Analysis Data Exploration Total Percent
Information Consumer 80% 20% 0% 100%
Business User 50% 50% 0% 100%
BI Expert 0% 0% 100% 100%

Definition
The central objects upon which reports and analyses in NetWeaver BI are based, are called InfoCubes. An InfoCube describes (from a reporting point of view) a self-contained dataset, for example, of a business-orientated area.
An InfoCube has a particular type:
BasicCube which is a collection of relational tables arranged according to the star schema: A large fact table in the center, surrounded by several dimension tables.
MultiCube which is based on the basic cube. It combines data from several BasicCubes/RemoteCubes, and brings it together into one context. The MultiCube itself does not contain any data; its data comes exclusively from the BasicCubes it is based on.
RemoteCube to carry out reporting using data in external systems without having to physically store transaction data in NetWeaver BI.
Only BasicCubes physically contain data on the database. MultiCubes and RemoteCubes simply display logical views of a dataset. The InfoCube type is not important, as far as reporting is concerned. A query definition always refers to one InfoCube. The difference between the InfoCube types becomes important at the point when you select data for the query.
InfoCube types: From the list below you can choose additional InfoCubes, just take the information and fill it in the questionnaire.

Specifics for InfoCubes
Dimension
A grouping of those evaluation groups (characteristics) that belong together, as regards contents, in one generic term. With the definition of an InfoCube, characteristics are summarized into dimensions in order to store them in a table of the star schema (dimension table). An InfoCube has no more than 16 dimensions, of which three are standard (package, time, unit) and included in the sizing by default. You can therefore enter only 13 dimensions at most.
Key figures
Values or quantities, such as sales revenue, fixed costs, sales quantity, or number of employees.
In addition to the key figures saved on the database, you have the option of defining derived (calculated) key figures in the query definition in the Business Explorer. Such key figures are calculated using a formula from the key figures of the InfoCube.
Examples of derived key figures are "sales revenue per employee" (sales revenue divided by number of employees), "variance as a percentage", or "contribution margin".
Initial load & periodic load
Initial load: Specify the estimated number of records which you plan to load into the cube initially.
Periodical load: Specify the estimated number of records which are loaded in your periodical upload process. You should take into account that you upload data volume grows with time.
Number of periods
Specify the total number of uploads which will be kept in the InfoCube. Example: if you want to keep weekly data for 5 years, you should enter 260 (52*5)
Short text
If you have several different InfoCubes of the same type, use short text to attribute names in order to identify them more easily.
DataStore Object
DS OBJECT Definition
A DataStore Object serves to store consolidated and debugged transaction data at a document level (atomic level). It describes a consolidated dataset from one or more InfoSources. This dataset can be analyzed with a BEx Query or InfoSet Query.
A DataStore contains a key (for example, document number/item) as well as data fields that can also contain character fields (for example, order status, customer) as key figures. The data of a DataStore Object can be updated with a delta update into InfoCubes and/or other DataStore Objects in the same system or across systems.
In contrast to multi-dimensional data storage with InfoCubes, the data in DataStore Objects is stored in transparent, flat database tables.</b>Hi,
BPS ;- Here you need to decide if you r really going to use this...If your are not going to use Business planning and simulation then skip this part.
In case of no. of users ....Take information from your client that how many no. of users will be there and then distribute these user as per gide lines given by sap. ( In quick sizer this help is available on market place )
Then decide which modules u r going to take in BW.
( In our case BW implementation is limited to SD, FI and CO. )
After this talk to your functional people and decided how many records will be generated per day for each module and for each functionality.
This is required to decide disk space.
Then list down all the infocubes and ods which are installed count dim. and key fig. for each cube. For ods count key fields and data fields.
Hope this helps....

Can't initiate a video conference from Mac to PC wtih iChat and AIM
I am using iChat on an iMac intel core duo and trying to video chat with my dad on a PC laptop using AIM 5.9. We can both invite the other to video chat, however when either one click to accept various things keep us from initiating the chat. One message we get says a firewall may be the problem. My firewall is turned off. He is running Norton. But we tried with that firewall turned off as well as the windows firewall tirned off. At the moment we are on the same network connected via a 2wire router (Myself wirelessly and he via ehternet). I have tried various settings with the router firewall including setting the PC to DMZ and the Mac to the settings specified on portforwarding.com.
When I initiate the conversation from the Mac he gets a brief flicker like the video window is opening and then it closes; meanwhile my computer says waiting for response until it gives up. When he initiates the video chat and I accept I get the message that the chat failed because I did not respond even thougth I clicked accept. He gets a mesage that the chat failed and the reason may be a firewall.
Any ideas on how to get this to work so that we are able to video chat. Also he will be returning home in a few days and using a linksys router.
Any help or ideas to try would be greatDear Ralph,
Sorry for the confusion, I did assume you were an Apple empoyee. Your knowledge about iChat is stunning. I appreciate your effort to help users by sharing your knowledge with such dedication. I do apologise.
Regarding:
Port forwarding is being automated and static ip addresses will be generated automatically.
Let's call it redirection (the handshake indicates the port to forward to).
When you have NAT running in your home you have the entire Internet available to all your machines. What if you have a machine behind the NAT gateway that needs to be accessed from outside? This is where redirection comes in. Redirection allows incoming traffic to be sent to a machine behind the NAT gateway.
An example:
rdr on tl0 proto tcp from any to any port 80 -> 192.168.1.20
This line redirects TCP port 80 (web server) traffic to a machine inside the network at 192.168.1.20. So, even though 192.168.1.20 is behind your gateway and inside your network, the outside world can access it.
The from any to any part of the above rdr line can be quite useful. If you know what addresses or subnets are supposed to have access to the web server at port 80, you can restrict them here:
rdr on tl0 proto tcp from 27.146.49.0/24 to any port 80 -> \
192.168.1.20
This will redirect only the specified subnet. Note this implies you can redirect different incoming hosts to different machines behind the gateway. This can be quite useful. For example, you could have users at remote sites access their own desktop computers using the same port and IP address on the gateway as long as you know the IP address they will be connecting from:
rdr on tl0 proto tcp from 27.146.49.14 to any port 80 -> \
192.168.1.20
rdr on tl0 proto tcp from 16.114.4.89 to any port 80 -> \
192.168.1.22
rdr on tl0 proto tcp from 24.2.74.178 to any port 80 -> \
192.168.1.23
A range of ports can also be redirected within the same rule:
rdr on tl0 proto tcp from any to any port 5000:5500 -> \
192.168.1.20
rdr on tl0 proto tcp from any to any port 5000:5500 -> \
192.168.1.20 port 6000
rdr on tl0 proto tcp from any to any port 5000:5500 -> \
192.168.1.20 port 7000:*
These examples show ports 5000 to 5500 inclusive being redirected to 192.168.1.20. In rule #1, port 5000 is redirected to 5000, 5001 to 5001, etc. In rule #2, the entire port range is redirected to port 6000. And in rule #3, port 5000 is redirected to 7000, 5001 to 7001, etc.
Static ip addresses are necissary to ensure that the router does not hand out the same ip twice, hence my question about the data transferred when a user connects his new mac to the one wich was set previously by the user (or other user). I think this information is explained in the Network Traffic Analysis you direct iChat to when they are asked to port forward (manually). I do not know the url by heart but it should be a known link to you.
Regarding auto response:
Sometimes you have to consider whether a very direct (and unelegant) interveniance in the software outweights the malfunction of an application that is causing a lot of trouble and inconvinience to Mac users. Personally I think that in this case the risk of being disturbed (still the same as anyone who askes for attention using chat or even phone) outweighs the much more irritating and incomprehensible "user did not respond" message and thus not being able to use one of the main features promised and promoted by Apple.
Yes life is inconsistent,
at least life is not sold to you.

I need some advice buying a compatible piece of hardware.
I want to buy a 4 bay USB enclosure. The problem is, there are many of them out on the market and I want to make sure I find one that's properly compatible with OSX. The most important thing for me is that the device power off and on when the Mac goes to sleep and wakes up, without the "device wasn't properly ejected" message everytime I wake it up from sleep. I'm hoping some of you guys have a few of these and can share your experiences with regards to how well they work.
I'm not looking for a NAS, I don't care if it has any kind of raid support or some sort of backup solution. I just want it to power down during sleep and power up on wake without any errors. Any help would be much appreciated.There is a layered model for building infrastructure
core layer
distribution layer
access layer
The core layer needs to be fast most of the time layer 2 on some optical systems
Then you have the distribution layer. this is where you connect your servers and traffic analysing on layer 3. (like Cat6500 switches)
Then the access layer thats where you connect the end nodes. (like Cat4500 switches or 2950)
It is wise to segment your network into different VLAN's Like a seperate server VLAN and some client VLAN's, number of client VLAN's depents on the number of end nodes.
You can use multi layer switches (a MSFC card in 6500 switch) for routing between the VLAN's
For redundancy you can use for example 2 6500 switches with MSFC where you implement HSRP to have redundant gateways for clients and servers
For security you have to create some access-lists on the VLAN interfaces on the MSFC so you can implement traffic filtering between VLAN's
Do you also have a internet connection (firewallzone) in that case create a sepearate VLAN in which you connect the (PIX)firewall.
Do you need any more information?

I need some advice on a small servers network please !!
hi every one.
i need a small help please.
i have a collage project that is upgrading a network and my part is the server's network. actually it is 65servers, windows and non-win.
i wish to know what are the important issues that should be considered in connecting the servers with the rest of the enterprise?
i thought of some,but i need some deatails how to start working on it;
pls add any more or try to explain what do you think should be done in it:
*trafic analysis, but where?
*redundancy and failure backup
*security
*authorization, is VLANs sufficiant?
*server loads, how to calculate it?
Is there a special topology for server networks?or layering?
regards;

Windows updates this morning gave me a different firefox: the Customize box includes fewer choices. No Text and Icon, which I want. Also, this new version dropped my Autofill.

Landscape mode trash can GUI issue
This is a minor problem but one that surprised me that Apple didn't catch. When emptying the trash can in landscape mode in email, the lid of the trash can opens up and beyond the grey border. That's a rather ugly GUI effect.
