Firefox has console log limits that can be configured to my understanding, but I'm thinking the IE11 console also has a limit on the number of messages it logs before it fails and stops logging.
I was wondering why my later log messages were not showing up in the log and I would see console warning text of "An error has occurred in the JavaScript Console. Functionality might be affected." when there was no error logged.
So I stuck a simple loop to generate a bunch of log messages to the console.
var li=0;
for (li=0; li<500; ++li) console.log("li %d", li);
console.info("Finished with list of log entries.");
Along with the other informational console log messages I had (6 others) the list ended at 499, so I bumped up the cutoff to 5000:
var li=0;
for (li=0; li<5000; ++li) console.log("li %d", li);
console.info("Finished with list of log entries.");
Now the logging ends at "li 994" as the last line.
The "Finished..." line doesn't even display.
Looking up the console to see how many messages were displayed, I see there are 6 others, not of the "li xxx" type.
So it appears that IE11 has a console limit of 1,000 entries and the stops logging and fails.
Can someone confirm and is there a way to set that limit higher?
My javascript code does some array processing and there is a lot of array dumping of data that goes on. I'm using console groups and they work, but when the entire logging shuts down after the 1000th message, that is a huge problem.

Hello all and thanks for viewing this question,
I have a program that users get access to via a login screen. Once the user's credentials have been validated on the login screen, the main program is called (from the login screen) and the login screen disappears. All good. However, if the session crashes (or I press CTRL-PAUSE), the main program is terminated and I end up at the initial login screen. I'd have assumed that after a session crash, Progress (11.4) should take me back to the OS (Windows Server 2012), but not back to the initial screen. I have tried placing QUIT in different areas of the program, but Progress still takes me back to the initial screen, while I need it to quit completely. Any thoughts would be greatly appreciated. Thanks!
It's the AVM's default behavior to rerun the startup procedure after a STOP condition has occurred that was not handled.
You can add an
ON STOP UNDO, RETURN "stopped" .
option to a DO, FOR or REPEAT block close where your "crash" happens. Then the calling procedure could check for the RETURN-VALUE of "stopped".
Assuming you are on a recent version (OpenEdge 12.x), you can also use CATCH Blocks for Progress.Lang.Stop:
CATCH stopcon AS Progress.Lang.Stop:
QUIT.
END CATCH.
I think that your use of the word "crashed" is very, very confusing. If your session actually "crashes" in the usual sense that _progres (or prowin if this is Windows) terminates, then you would not have any locked records remaining. You would also have a protrace file that would help you to identify where the issue occurs.
Incidentally, you could add error logging to the client startup to determine where the errors that QXtend cannot find are occurring:
_progres dbname -p startup.p -clientlog logname.log
You have not shared any code so I can only guess but, presumably, you are running your login program via the -p startup parameter.
Correct me if I am wrong but something along these lines:
_progres dbname -p startup.p
The startup program then runs whatever it runs to get you logged in and run the application. Maybe something like this:
/* startup.p
*/
message "(re)starting!".
pause.
run value( "login.p" ).
run value( "stuff.p" ).
message "all done".
pause.
quit.
And:
/* login.p
*/
message "hello, logging in!".
pause.
return.
Along with:
/* stuff.p
*/
message "hello, doing stuff!".
pause.
run value( "notthere.p" ).
message "hello, doing more stuff!".
pause.
return.
At some point an error occurs (you seem to want to call this a "crash"). I have arranged for a serious error to occur when stuff.p tries to "run notthere.p". So if you run my example you will see the behavior that you have described - your session "crashes", the startup procedure re-runs, and you get to the login screen again.
To change that and trap the error simply wrap a "DO ON STOP" around the RUN statements. Like this:
/* startup.p
*/
message "(re)starting!".
pause.
do on error undo, leave
on endkey undo, leave
on stop undo, leave
on quit undo, leave: /* "leave", exits this block when one of the named conditions arises */
run value( "login.p" ).
run value( "stuff.p" ).
/* we just leave because we finished normally */
end.
message "all done".
pause.
quit.
You mention QXtend so I am guessing that MFG/Pro is involved. If you cannot directly modify the MFG/Pro startup procedure (as I recall that would be "-p mfg.p") just adapt the code above to be a "shim" that runs mfg.p from within the "DO ON STOP..." block.
I believe I have found a way to quit the initial login screen when this appears as the result of a session crash, by using the the ETIME function. Thanks again, Mike for your response.
I can write a query in application insights that gives me a percentage as a scalar. I want to create alert if that percentage is > X . How can this be done using log based alerts?
Basically, I have a lot of machines that send telemetry to application insights. Sometimes they log some exceptions. I send MachineName in customDimensions for all the logs. So I can get the names of all the machines that sent logs in last 24 hours. The exceptions are also sent with MachineName in customDimensions. When a particular error is raised by more than X% machines in last 24 hours, I want to raise an alert.
The way to write alert logic is using 'Number of Results' which cannot be used for this since it automatically adds '|count' to the query. The other way is using 'Metric Measurement', which I am guessing should help me raise an alert like this but I'm unable to figure out how.
I can get the total machine count by this query:
let num_machines = traces
| summarize by tostring(customDimensions["MachineName"])
| count;
I can get the number of machines that reported an exception like this:
let num_error_machines = exceptions
| where customDimensions["Message"] contains "ExceptionXRaised"
| summarize by tostring(customDimensions["MachineName"])
| count;
finally, i can get the percentage of machines that raised the issue like this:
print toscalar(num_error_machines)*100/toscalar(num_machines)
I am not sure how to use this result to raise an alert using MetricMeasurement. This needs to be modified somehow to get AggregatedValue and use bin, I am not sure if that is possible / how that query will be.
Sorry for the late reply. I've tested in my side and met many problems indeed.
I found that alert rule doesn't support to monitor the percentage number of the result, it only supports the numbers of query result and Metric measurement. So I think you may give up the percentage and use the num_err_machine like the screenshot below
Pls note, you can't append " ; " at the end of the query or it will give an error like The request had some invalid properties

Logging Messages from Java Class back to the Karate Report
(3 answers)
Closed 1 year ago.
While using Karate I need to receive information from browser console (e.g. Firefox) when an error occurs.
How can I do it with Karate?
1) Is there any way to save the browser console log? (or attach it to features report)?
In Selenium I use this to log browser console in case error occurs:
if (webDriver != null) {
LogEntries logs = webDriver.manage().logs().get(LogType.BROWSER);
for (LogEntry entry : logs) {
LOG.error(entry.getLevel() + " " + entry.getMessage());
}
}
2) Is it possible to trigger it in similar way to take screenshot after scenario?
e.g (after scenario screenshot when some error occurs):
configuration:
karate.configure('afterScenario', read('afterScenarioScreenshot.js'));
afterScenarioScreenshot.js:
function()
{
if (karate.info.errorMessage) driver.screenshot()
}
Thank you for any idea.
The only suggestion I have is to use showProcessLog: true in the driver config.
Now you should see any FireFox process (console) logs in-line with the HTML report.
There may be ways to switch on the detailed logging that you want. Note that you can add command line options using addOptions in the driver config: https://firefox-source-docs.mozilla.org/testing/geckodriver/TraceLogs.html
The "WebDriver" way to switch the log level is by using the driver "capabilities". Refer the above link and see if you can set this for FireFox. It would be good if you post back your findings so that it helps others. In Karate, you use the webDriverSession to configure this.
The logs will be in some file. You should be able to write some code to scrape from it any time during a test if they don't show up in the HTML report.
If you need something more, please consider contributing code.
I'm using Zeos and SQLite3 DB in Delphi
ZQuery2.Close;
ZQuery2.SQL.Clear;
ZQuery2.SQL.Add('SELECT * FROM users WHERE un = ' + QuotedStr( UserName ) );
ZQuery2.Open;
OutputDebugString(PWideChar( ZQuery2.FieldDefList.CommaText )); // log : id,un,pw
OutputDebugString(PWideChar(ZQuery2.FieldByName('pw').AsString)); //causes error sometimes
the code is working but sometimes I get the following error message
Exception class EDatabaseError with message 'ZQuery2:Field'pw' not found'.
This is odd because a field of a dataset shouldn't just disappear while the app is in the middle of running, especially if other fields are still operating normally. So, I would suspect something like a memory overwrite being the cause.
Memory overwrites usually happen when something is written to the wrong place in memory, overwriting what is there, usually because of an incorrect pointer value or a so-called "buffer overrun" where the writing operation carries on beyond where is should stop. Usually, the pointer value is so wildly wrong that the OS can detect it and raise an AV, but sometimes it is less obvious.
Delphi's memory manager has a 'full debug mode' which adds special checks for this condition, see here.
I suggest you enable full debug mode as per the linked document and wait for the exception to occur.
Just this morning when trying to view the Data Explorer UI for an Azure Cosmos DB table the window is totally blank and I see no rows (the table should not be empty). The only connection to this table is a Python script that pushes in simple rows with only a few variables however this has also stopped working just this morning.
I am still able to connect to the table service properly and I've even been able to create a new table through my Python script. However, as soon as I call table_service.insert_or_replace_entity('traps', task) ('traps' is the name of my table and task is the row I'm trying to push up) I receive back an HTTP Error 400. The request URL is invalid.
For reference, my connection in Python is as follows where Account_Name = my personal account name and Account_Key = my personal account key.
table_service = TableService(connection_string="DefaultEndpointsProtocol=https;AccountName=Account_Name;AccountKey=Account_Key;TableEndpoint=https://Account_Name.table.cosmosdb.azure.com:443/;")
for i in list(range(0,len(times))):
print(len(tags))
print(len(times))
print(len(locations))
task = {'PartitionKey': '1', 'RowKey': '{}'.format(tags[i]),'Date_Time' : '{}'.format(times[i]), 'Location' : '{}'.format(locations[i])}
table_service.insert_or_replace_entity('traps', task)
UPDATE
In reference to the HTTP Error 400 I discovered that I was trying to push a \n at the end of each of the tags string (i.e. tags[0] = 'ab123\n'). Stripping out the \n has resolved the HTTP 400 error but I am now receiving The specified resource does not exist. message when I attempt to upload which makes more sense as at why my Data Explorer is blank. I have tried uploading to a new table but its the same thing.
Second Update
Silly mistake on resource not found error was that my table is called "Traps" not "traps". Data appears to be uploading correctly now on the API side. However, the table is still not displaying at all in the data explorer page of the Azure portal. If anyone has insight on this it would be appreciated because the explorer is super helpful while we are still in development.
Third Update
I am able to connect to the table/database through Python and query data effectively. It all seems to be in there and up to date. The only thing I'm left unsure about is why the Data Explorer is not displaying properly. Aside from that, my recommendation is to obviously check your capital letters (my usual mistake haha) and DO NOT try to push up line feeds (\n) in the task/payload.
Want to provide an official update and response to your issue. This issue is being Hotfixed with an ETA rolled out by Monday (09/24/2018).
