VI metrics: number of diagrams

• Programming VI metric: number of nodes?

  Is there a way to run a program a number of nodes on a VI?  I looked around and can't seem to find anything about it.  VI of script that would do for me?

  Thank you

  Assuming that we mean the same thing by number of nodes, script could do for you.  You can return a list of nodes on the comic using the Nodes of the [] property and take the length to get the number.  It is fraught with peril, since as far as scripting is concerned, each structure (while loop, loop, etc.) is considered to be a separate diagram you need one recursive procedure to count everything.  Fortunately, a kind soul at NOR did the work for you, and there is a VI to do this work.  In vi.lib/Utility/traverseref.llb there is a VI called TRef across to References.vi, and by typing "Node" as the class name, you will get all the nodes.  What you would do with it, I don't know.

  

• How calculated the code coverage in unit test infrastructure

  I'm looking for documentation on how the unit test framework calculates code coverage.

  I just recently installed the unit test framework and I had mixed results with the code coverage feature.  I manually calculated all the branch points in my vi, but the framework calculates more that I can think of, which gives a value of code coverage less than stellar (51%).  Is there documentation for how it is calculated?  I'm either missing something fundamental, or there is a bug with the framework.

  My vi consists of a loop (with shift registers) uninitialized which runs once.  On the inside of the loop is a business T/F structure that leads to a listed case structure possible two cases (one of which is the default value)... pretty basic.  Inside one of the structures is a loop and the other is cross.  For some reason, the unit test framework calculates 7 "flags chart run.  I use the method of "external" test harness to call all my test cases for the vi under test, b/c frankly it was easier to use than the UI provided.  I don't know if this is the cause, b/c I saw the other oddities when using it, which I'll save for another thread of discussion.

  Code coverage is calculated by dividing the number of diagrams, code that was executed by the number of diagrams in your VI altogether. Each VI has at least 1 schema (schema-block real). Loops have a single diagram each, case structures and sequences have a single diagram by image and so forth (=> from your description, your VI has at least 7 diagrams). You can double-click the patterns that were not executed in the Unit Test Framework results dialog box to be displayed.

  This approach does not reflect the amount or complexity of the code that contains each diagram. We looked at various ways of counting nodes, terminals, controls, son and other, that would give you a number that reflects your code with more precision. Unfortunately, neither of these approaches gives values that can easily be understood without some knowledge about the inner workings of LabVIEW. We chose to go with a solution that is completely transparent to end users.

• facing issues while recreating studio 3.1 short page that was created in the studio 2.4

  Hi all

  I've recreated the studio 3.1 short page which I created on short 2.4 but I face below question.

  1 al ' short 2.4, we added the filter component range, but I can't find the same short 3.1. It has been renamed.

  2. in short 2.4 in serach box unrolling shows that all, events, codes but in short 3.1 it shows as OPSM (ALL), OPSM (Events). Can be renamed and their order can be changed?

  3. in all the graphs in short 2.4 in the scope of series we have column EVENT_ID (sum), where we entered the number of events such as Custom name and selected County as the aggregation method, in short 3.1 I can't find number of aggregation method. Can you please let me know how I can get number of aggregation method.

  Thanks in advance.

  Hi Amrit,

  What you see is the difference between the title name/axis for the metric group and the individual name of a metric in the metric group.

  The legend (which identifies the colors used by bars) shows the real names of metrics. You cannot change the name of the metric. Number of records is always the number of records.

  The axis title is a label used to account for all the values are displayed, because you can display several features together.

  For example, go to your chart, and then drag another metric in the same group of metric as the metric of number of records (there is always an empty slot to add an another metric to the Group). Define an axis for the metric group title. When you view the chart, the title of the axis uses your custom value. The legend shows two blocks of color, each bearing the name of the metric (number of records and what is the name of the other metric).

  In your case, you are only viewing a metric, but it is still technically a group of metric. Customization of the label of the axis does not change the name of the metric.

• How to make the collection interval less than 1 minute?

  Hello
  
  I have a metric that I wish I had a report on trends in second instead of / minute. Here's my metric definition.
  
  < name metric = 'number of messages sent.
  alias = "SentMessageNum."
  category = "FLOW".
  collectionType = "trendsup."
  indicator = "true" / >
  
  I read of http://support.Hyperic.com/display/doc/measurement+plugin#MeasurementPlugin-MeasurementPluginmetrictag . There is a "gap" and a field "rate". Then I updated my metric definition to be
  
  < name metric = 'number of messages sent.
  alias = "SentMessageNum."
  category = "FLOW".
  collectionType = "trendsup."
  interval = "1000".
  rate = 1 "s".
  indicator = "true" / >
  
  After you restart the agent, I found Hyperic stop collecting data for this measure. All data in the tab 'Metric data' remains to the number before I made the change.
  
  So, how have Hyperic save data per second? Thank you very much.

  Hello

  Hyperic HQ does not support a collection within a 1 minute interval.

  See you soon,.

• Help Plugin script

  I created a perl script to give me information of process through top (just like a plugin practice, not really important) and I can't seem to make it work.
  It returns pair = key information of value, and I created a xml descriptor that I think I've done wrong.
  
  The key / value displayed as such:
  Availability = 0
  number = 107
  sleep = 106
  running = 0
  oncpu = 1
  
  And my xml file looks like this:
  < plugin >
  < = "procmon" server name >
  "< name of the filter ="script"value ="... /scripts/proc.pl"/ >
  < config >
  < / config >
  < plugin type = 'measure' class="org.hyperic.hq.product.MeasurementPlugin"/ >
  < service name = 'Process' >
  < config >
  < / config >
  < name of the filter = 'template '.
  value="exec:file=%script%"/ >
  < name metric = "availability".
  Council = "${model}": availability ""
  indicator = "true" / >
  < name metric = "number of processes.
  category = 'USE '.
  indicator = 'true '.
  model = "${model}: number" / >
  < name metric = "number of processes of sleep."
  category = 'USE '.
  indicator = 'true '.
  model = "${model}: sleep" / >
  < name metric = "number of Running Processes.
  category = 'USE '.
  indicator = 'true '.
  model = "${model}: running" / >
  < name metric = "number of processes on the CPU.
  category = 'USE '.
  indicator = 'true '.
  model = "${model}: oncpu" / >
  < / service >
  < / Server >
  < / plugin >
  
  Yet once, I can't seem to get this to work, where have I wrong?
  
  Thank you

  On the right, display your xml file!

  Also make sure that the two files on the server and the agent are identical. However, it seems that this server does not know that there is a configuration setting for your path of the script. I know that you have added the config param if you were able to read the parameters using the market dry.

• Create links of slider in actionscript

  I have a loop that creates a number of diagrams while running (based on requests from users) and adds them to my main application. I would like for a slider to also associate with each chart so that the width of the chart can be adjusted. I can create everything, but I don't know how to make connections between the width of the graph and the slider since everything is in actionscript. Here is an example of the relevant code for the loop.
  
  
  

  Well, I figured out how to do this the old-fashioned way. I just added two methods to my custom cursor component and the problem was solved. Here is the final version of the cursor:

• Metric string to a number

  Is there a way to convert the string "1ms" in the 0.001 number?  Same thing with the µ (micro), k (kilo), M (mega) and all the other metric symbols?  I can do it manually without problem, but I thought someone might have already done this.  Thank you.

• Push the details of notifications: 'Number of devices' and 'sent devices' metric

  After sending notifications, push or text of a folio is bottom of Adobe Digital Publishing Suite measures can be obtained which indicate:

  • Number of devices
  • Devices sent

  

  This is probably the number of devices which received notification of a total number of devices?

  How is deducted the total number of devices?

  Notification Push of DPS Service maintains the list of devices that have opted in receiving push notifications.  This is the "number of devices" that can be targeted.

  Hey guys - so I do business with a bit of a problem in number. I have a number table - the table above is a simplified representation of the corresponding parts of the table. The left column 'name' is a series of 12 names repeated and 0 missing values. The "string" middle column is a column that has a lot of missing values by a formula based on another column that is not relevant to this problem. Who is not missing is all strings. The problem I have is in the 'metric ': right column

  I am trying to create a dynamic formula which will result in the numbers and blanks, exactly as above. My goal is to create a formula that, for each line, account the number of whites in the column 'chain' until we reach an empty 'string' which occurs next to "namesake" as in the line of housing the formula - and if there is no such a situation, so that it is empty. For example, if the second row (including header row) bears the name of "Matthew". The next time that a white 'string' occurs next to the name "matthew" is tenth. The number of whites that occur between the second row, and the ninth is 5 (lines 2, 3, 5, 6 and 8). I manually coded a small part of the table to use something like this (which would be installed in cell C2 in this example):

  = IF (B2 = "", COUNTBLANK(B2:B9), "")

  This formula produces the correct number for the first row of data (5), but it does not dynamically fulfill what I'm trying to do this since I am currently having the formula to find the next blank 'chain' that occur next to "name" in the formula line.

  I hope that someone has encountered anything like this before. I tried to go through all the functions and numbers from formulas, but so far I have not found much success.

  Hi BaronDe,

  I need to ask, "why you try to do this? So what you want is possible it will be a complex solution. It may be much easier to get your information in a different way. Indicate these blanks?

  You should know that COUNTBLANK() will not count a cell with a formula, even if this formula resolves to «»

• Batch conversion metric, temperatures, etc. ?

  Imagine a data column in a Numbers spreadsheet, where each digit refers to feet. Is it possible to convert the entire column to a metric equivalent? And can we do the reverse - convert meters to feet?

  What conversion miles square kilometers square, celsius, fahrenheit and vice versa?

  Thank you.

  Hi David,

  What you ask, it's easy to do in number. You just need to know the conversion factor. So many feet per meter and you have your formula. Since C ° and F ° is a little more interesting allows this.

  

  You can see how I created a formula in number to account for the conversion of ° C to ° F. Then I filled it to the bottom of the column. You can do the same with any of your examples.

• Reach registration number OR

  I am Setup extended to the acquisition of multiple discs, number of records, set to 50 for 8 channels of 50000 samples. I want to know after 50 triggers received by scope will be stop acquisition or it will start to crush the Chronogram of 0.

  I ask this question because everything in extraction of waveforms, I'm more than 100 records, acquisition of data and the scope does not have 50 after triggers, it is waiting for the next release I stop it manually.

  Hi Somu26,

  What digitizer/oscilloscope do you use?

  «I want to know after 50 triggers received by scope will be stop acquisition or it will start to crush the chronogram 0.»

  The short answer is that the acquisition stops.

  The behavior of the driver NOR-SCOPE is defined and described by the following of Acquisition Envine diagram States-transitions.  This documentation can be found in the help file under the heading devices > state diagrams.  It is also documented online here: http://zone.ni.com/reference/en-XX/help/370592W-01/digitizers/5122_state_model/

  

  In general, an acquisition ends when all configured samples were acquired.  By default, there is only one folder, then when all the samples in the record is acquired, the acquisition to the 'Full record' State transistions, then to the State 'Done '.  In a multi-record acquisition setting, the unit will continue to acquire data until all records have been acquired.  Once there is no more registration acqure (she has acquired every 50), it will then be transiition as 'Done '.

  Note that the Green States that are the only countries in which the data is written in the on-board memory, when an acquisition is completed, no additional data is written to on-board memory, so no chance for the data to be overwritten.

  I hope this helps answer your question.  I strongly recommend you and any study of customer digitizer/oscilloscope, as this picture of the State, like most of the questions about the behavior of the device (acquisition, trigger, timouts, etc.) can be answered in it.

  Kind regards

• What this block diagram?

  What this block diagram?

  Match a VI Modbus Library. But I have because if the block is configured to write multiple coils in the coils because reading is set to 1?

  All this work?

  Sorry if the question is a beginner.

  

  In this block diagram, 'Coils Read' and 'Write multiple coils' are enumerated values (or possibly ringtones of appeal, which is not serious for the purpose of this explanation). Enumerations assign names to numbers, to make them easier to read. The coils Read command is set to 1, the command to write multiple coils has a value of 15. You don't need to worry about this number, however, because the enumeration takes care of it for you.

  The constant cluster containing coils of reading is there just to provide the correct data type (a cluster with the right items). Almost all the elements of the latter shall be replaced by the values of wired in the Bundle to node Name. For example, the value of reading coils is there as a placeholder for any function Code. the actual Code of the function is defined by plugging write multiple coils in Bundle by name.

• Clean using SubVIs block diagram

  Hi guys and welcome to my first post!

  I m a bit new to labview, so be a little patient, if I do not understand everything immediately

  Im working on an existing program that is used to control an MCU on BabyLin on my front, although I have a visualization to see live changes to the system. The program works very well so far, but I m trying to clean up the block diagram. This should be done by subvis, right? I ve read a lot about the size of the block diagram should not increase my screen. Well, im at a length of about 3 x 2 screens (24 "!) after trying to use subvis and to shorten the distances between structures. The only things remaining are huge amounts of local variables and references (they existed already before I got to know the program), mainly for viewing. If I create a Subvi part containing the people of the country, it will change the references that does not make the program more readable (and small), and I guess I can't put a new Subvi on references + Subvi.

  You have any ideas what to do? I hope that I forgot something, otherwise, do not hesitate to ask.

  Kind regards

  To get a handle on the structure of your high-level code, write down (as if you were telling your boss or tell your wife - who knows, they might be the same person!) that you are trying to do.  Keep it pretty General.  You specified a number of steps?  So maybe the top level should be a State Machine, or a message in queue manager.  Describe you something that works at a constant speed, generating data that you have to manage "on the fly"?  Maybe it's a design of producer/consumer.

  You have a lot of initialization?  Put in a Subvi, bring the 20 son out in a bundle (it's "Boss-word" for a Cluster).  Your main program must have a few loops, with values that persist (possibly changing) during the program running in Shift Registers near the top of the loop, with tables and Clusters used to keep related items "consolidated".

  Not too bothered by the size of your routine - I recently downloaded a monster 50-monitor the Forums (I did not even try to understand), up to 6 monitors is nothing!

  Let "encapsulate the function" and "hide details" to be your guide in the reflection on the creation of the screws.

  Bob Schor

  To develop on the analogy of Bob, each talking point can be a Subvi.  In other words, code group associate subVIs.  The advantage of this is that it is much easier to solve problems because all errors will be localized to a Subvi.  Errors no longer Chase around the block diagram.  I guess you can use your current VI as an example of what NOT to do on the block diagram.
