How do I generate logs from my rec and post script

[IreneEgbulefu1]

I created a python script to reconcile all edits on the users versions, then  post the reconciled version to a QAQC and then to the sde or dbo default version. After this process the script will proceed to compress analyze and rebuild indexes for the tables in the sde database. This script will be scheduled on windows scheduler to run silently at 2:00am on Thursday and  Saturday morning when users are offline.

If there should be any error encountered, the script is to print the errors and also generate a log file containing the errors and store the logfile with date and time in the specified drive location. Since the script was scheduled to run behind scene on windows scheduler, it was difficult for me to see errors when it happens. This was a big issue because users edits weren't reflected on our default database after sometime due to the error encountered by the script, his actually necessitated the need for a functional logfile that will enable me identify the errors.

The initial problem I had was that  the script executed very well but could only print the errors on the screen but it generates an empty logfile.

This was corrected by putting in 3 lines at the end of the script to get it to write the printed errors intothe logfile, save it with time and date.

The Initial Script - executes but generates an empty log file

I don't necessarily have an answer, but can you repost your code using https://community.esri.com/people/curtvprice/blog/2014/09/25/posting-code-blocks-in-the-new-geonet?s...‌  It will make it easier to read and comment (will have the line numbers, etc).  thanks

[DanPatterson_Retired]

It would be nice if the question were left to see what it looked like reformatted

[RebeccaStrauch__GISP]

Agreed.  I thought it was an interesting topic "How do I generate logs from my rec and post script" and was hoping to see the result too.  Something I could use.  Guess I'll un-bookmark.

[DanPatterson_Retired]

MMathias-esristaff‌ are there any undelete tools for Moderators?

[MichelleMathias]

Hi Dan, not that I know of. I will confirm with Jive but I am pretty sure there aren't any undelete options for moderators. Even for full admin the undelete options are extremely limited and in my experience are not very helpful.

ooh! I apologize for deleting the post here. I thought the moderator did not want it posted here and so I deleted it.

I can still publish it again here and how I got the issue resolved if anyone is interested in it.

Please let me know if I am allowed to post it here.

[DanPatterson_Retired]

You sure can Irene... just use the code formatting that I suggested (see the link if you don't know how), otherwise it was unreadable

[RebeccaStrauch__GISP]

EgbuleI   Thanks for restoring your post with you solution.  I am interested in looking to see if it's someThing we could use.  As Dan mentioned, the comment re formatting the code was just to make it easier to read...as you have it now.  It can take a little while to get used to posting here, but it's a friendly, helpful community.  For some more tips, take a look  at https://community.esri.com/community/help-and-feedback/blog/2016/08/15/community-news-and-tips-how-t...‌

[DanPatterson_Retired]

Nice to see it back with the solution.... FYI rastrauch‌
