I want to ask for console input without disturbing the contents of the stack. However, the PULL function will always pull from the stack first if it is not empty. How can I do this?
Depending on the platform, you may be able to use PARSE EXTERNAL. Not every Rexx implementation supports it - it's not part of the ANSI standard. But, for example, IBM's TSO/E and z\VM implementations do. PARSE EXTERNAL always reads from the console, no matter what the contents of the stack.
Create a new stack prior to your PULL, delete it when you're done with the PULL.

So I have typical run of the mill logs from Nginx and tomcat servers which are just single line text files with typical log format. I have changed the tomcat access logs to output pipe delimited fields so I can easily process them using some unix scripts. I'd like to get rid of my unix scripts and move to using cloudwatch to process my logs in a similar manner, however I found out that cloudwatch really doesn't understand anything beyond timestamp, message, and logstream by default.
It will add fields using JSON, but JSON is verbose when it comes to log files. I'd like to just let it process a CSV file which seems like an obvious alternative to JSON. I'm willing to change my log format to meet a requirement like that, but I can't find any information about how I could do that.
Is my only option to translate my logs into JSON in order to add fields to cloudwatch? I am aware of the parse command, but I find that cumbersome to reconstitute my fields every time I want to build a query. Especially since these will mostly be access logs which will have numerous fields. I have aws cloudwatch log agent setup on my systems and I'm currently sending these logs to cloudwatch.
The closest thing there is to handling space delimited log files is to use Metric Filters. Or at least that's how the authors of CloudWatch designed it.

The best examples of this is here:

Not sure if this is going to work for what I'm trying to do with logs, but it's a start. And it's the closest thing to a proper answer. If you want it done right, you gotta do it yo'self.
Consider for example this modified Simple TCP sample program:
How can I display the current state of the program like
Wait for Connection
Connected
Connection terminated
on the frontpanel, depending on where the "data flow" currently is.
The easiest way to do this is to place a string indicator on your front panel and write messages to a local variable of this indicator at each point where you want to see a status update.
You need to keep in mind how LabVIEW dataflow works: code will execute as soon as the data it depends on becomes available. Sometimes you can use existing structures to enforce this - for example, if you put a string constant inside your loop and wire it to a local variable terminal outside the loop, the write will only happen after the loop exits. Sometimes you may need to enforce that dataflow artificially, for example by placing your operation inside a sequence frame and connecting a wire to the border of the sequence: then what's inside the sequence will only happen after data arrives on that wire. (This is about the only thing you should use a sequence for!)
This method is not guaranteed to be deterministic, but it's usually good enough for giving a simple status indication to the user.
A better version of the above would be to send the status messages on a queue or notifier which you read, and update the status indicator, in a separate loop. The queue and notifier write functions have error terminals which can help you to enforce sequence. A notifier is like the local variable in that you will only see the most recent update; a queue keeps all the data you write to it in the right order so would be more suitable if you want to log all the updates to a scrolling list or log file. With this solution you could add more features: for example the read loop could add a timestamp in front of each message so you could see how recent it was.
A really good solution to this general problem is to use a design pattern based on a state machine. Now your program flow is clearly organised into different states and it's very easy to add in functionality like sending a different message from each state. There are good examples and project templates for these design patterns included with recent versions of LabVIEW.
You should be able to find more information on any of the terms in bold in the LabVIEW help or on the NI website.
To make the question simple, I know that I can get some build information with https://jenkins_server/...///api/json|xml|python. And I get a lot of information for that build record.
However, I want to add more information to that build record. For example, the docker image created, or the tickets or files changed from last build to create release note, ... etc. How do I do that?
For now, I use a script to create a json file as an artifact and call that json file to get these information, but it seems a duplicate if I can add more data to the jenkins build object directly.
The Jenkins remote access API is designed to provide access to generic Jenkins-internal information, like build numbers, timestamps, fingerprints etc.
If you want to add your own data there, then you must extend Jenkins accordingly, e.g., by designing a plugin that advertises your (custom) information items as standard Jenkins-"internal" data. If you want to do that, you may want to have a look at they way fingerprint information is handled (I found that quite instructive).
However, I'd recommend that you stick with your current approach, and keep generic Jenkins-internal information separated from Job-specific data. It is less effort and clearly separates your own data from Jenkins' data.
I've studied BPMN in coursework; this is my first time applying it in real-work scenarios that don't follow any of my textbook examples.
I am trying to illustrate a process where a client can either upload a CSV file, manually enter records, or both. At the end of the day, all records are loaded to a production database via a script. At the moment, I've got it like this:
But, unless one reads the notes attached to each object, this tells me that uploaded AND manual data will be present.
In BPMN how would I designate that Path "A", Path "B" OR both, could be valid? How do I label the gateway? The scripting step I anticipate putting between the data input and the production database, but I'm not quite sure, again, how to specify that the script runs ONCE based on the presence of data from EITHER feed, not both.
What would this typically look like, and thanks in advance.
In BPMN to express that Path A, Path B or both could be valid ways forward, you can use an "inclusive or" gateway. I would typically label the split with a question and the outgoing pathes with the "answers", iow conditions under which the pathes are activated. If I understand your example correctly, a possible solution could look like the following.
Whether you want to use the task types I used, depends a bit on your more specific context. My task types in that example would mean that for the "upload" the process is "waiting for an incoming message", while in the case of manual entry it is "waiting for a user to complete the task" (by entering the required data).
The example also assumes that you know before you reach the inclusive or gateway which channels you will want to use this time.

DOS command to Display result on console and redirect the output to a file
tried various Google searches but nothing seemed to solve my problem.
Basically I'm working for a company who need me to work with their in place database and extract the various data need for reports. They are using Sqlite (please, I've heard enough comments about how it might not be the best choice for a DB, so leave them out) and I either want all my activity on Windows command prompt to be logged, or at least everything I do from the Sqlite command line to appear in a .txt, just in case I need to refer back to it later.
Can anybody here explain to me how to do this? I'm a bit of a beginner and need this stuff broken down step by step. Not done anything like this before.
Cheers!
I'm reasonably certain you can't do this directly -- i.e., the Windows command prompt doesn't provide a way to log the input you provide to it. You can capture outputs (e.g., from commands you run), but for your purposes that's probably not adequate.
You probably need to create a "shell" of your own that takes inputs from the user, logs each one, sends it on to the command prompt, captures the output from the command prompt, and logs that as well.
In an answer to a previous question, I posted some code that handles most of what you need to do. The big difference is that you'll want to look in its handle_output (for example) and instead of just displaying the captured output to the console, write it to a file as well. As it stands right now, that example redirects the child's standard input to come from a file, but changing it to read from the console instead should be fairly straightforward -- you'll basically use a function about like the handle_output and handle_error that it already includes, but instead of displaying output, you'll read input from the user, and each line you'll 1) write to the log, and 2) send to the child via anonymous pipe (much like handle_output and handle_error read from anonymous pipes).
