Title: Log to disk
Post by: Alberto on June 12, 2020, 08:48:00 AM

Hi, I have a server who suddenly stops working
I think may be its a halt or a stop, but I never see it, the real thing is that it suddenly disapears
I set the log to Display&disk but I never see any log file in the log dir
Or any way to debug it?
How to do it?

Simple steps to log to disk:

1. Create a global string variable GLO:MyLogFileName
2. Create a table.    Full Path Name:  !GLO:MyLogFileName;  In it, add a field: Line1 STRING(4000)
3. In your Web Server procedure, open the Logging Controls extension template
4. Fill in the fields for table, field, and GLO:MyLogFileName

Run the app.  Enable log to disk.  Log file will be created in the LOG folder.
If you're using an ASCII file, you will probably need to turn OFF log to disk to flush the records to disk.

Ok, I have a problem.
The log is saved ok to Disk while the server is up running.
I can inspect the log file while the server is running and if I close it.
Its an Ascii file.
but...
When the server halts by, I dont know which error, the log file is deleted.
The server stop running and the log file is not there.

I have some HALTS() mhhh may be I have to close the ascii file before...

Another thing I dont understand if why there are more tahn one log file in the same run, beein the logs as little as 3kb. See pic

each time you run the program it will start a new log file.

Thats no what its happening here, without closing the server there are many .log files, see pic.
Theres a new log file each MINUTE (if there are anything to log)

A new log file is created in the NetWebServer.OpenLog method if the file size exceeds Bytes(p_File) > self.MaxLogSize,
or if the log file is closed.

So perhaps add some trace code in there to determine which is happening. Also, if you CLOSE the log file then it'll have this effect.

Im not closing the file.
Ive added some trace lines and I dont understand why the file gets status=0
Please see pics.
