What if you want it back? In this post, I explain what changed, why, and how to get the functionality back--albeit at your own risk. For more, read on.
Why you may not agree with the removal
While some folks never use the CF Admin's logviewer feature (at "Debugging & Logging">"Log Files"), others DO rely on it, whether because they can't easily access the CF logs another way, or they just prefer this approach over other alternatives.
As for the asserted "security concern", some may retort that the CF admin is by default password-protected and more important accessible only via CF's built-in web server (at its non-standard port, which defaults to 8500), so they may feel that this removal (without any choice) was heavy-handed.
And in many forum threads and other social media, people are asking over and over how to get the log viewing capability back. While it won't interest some at all, and others will think it borders on being irresponsible to recover this functionality, I just can't help wanting to at least share these observations, and the "old" code and how to use it--with due warning of the risk.
How the change was implemented
I've studied the changes as of this update, and determined that Adobe has changed two folders controlling this functionality ("logging" and "logviewer"), and I offer the "old" versions of those here for you.
Curiously, the Oct 2022 updates do NOT backup the old version of the code in these folders, in the update's "backup" folder within the hf-updates directory. Normally, the updates DO otherwise make copies of whatever files/folders they change/remove.
Instead, I captured the version of these folders BEFORE applying the update, and I offer them in this zip below. Note that I offer a version (folder) for each of CF2021 and CF2018, as they do differ and you should use the one appropriate to your CF version.
Recovering the functionality, at your risk
So if you want to regain the previous log viewer, you can replace the "new" folders with these "old" folders, as I discuss below.
Before doing that, note that:
- You do this at your own risk. Perhaps in time Adobe will make more clear what the security concern is, and it may warrant reverting to their version.
- Beware that in any next CF update, that would replace these files and folders. CF Updates "lay down" a cumulative replacement of ALL folders and files that were updated in any and all prior CF updates, when doing each update. So if you want to get the log viewing capability back after such an update, you will need to repeat the steps below after each update--at least until Adobe perhaps relents and offers a new, secure way to view the log files.
- I'm offering things based on how I find them to work in early Nov 2022. Things may change over time. I can't commit to keeping this updated going forward. The information here should suffice for interested folks to follow-up.
How to recover the functionality
As for the steps, do the following for your cfusion instance and/or any other instances you may have (note that ColdFusion Enterprise, Trial, and Developer offer the ability to create multiple instances, which would be shown as a folder with the instance name as a sibling to the cfusion folder):
- In your ColdFusion2021 or ColdFusion2018 folder, find the wwwroot\CFIDE\administrator folder within your cfusion or other instance folder(s).
- Within that administrator folder, find its logging and logviewer folders.
- Copy those two folders to a new location or rename those in the current folder (such as logging_original).
- Extract the two folders from the zip, putting them in place where you removed/renamed the existing folders.
(If you prefer to use your own copy of the "older" folders, you certainly can. Just copy them from within the folder in step 1 BEFORE you apply the Oct 2022 updates, 5 for CF2021 and 15 for CF2018.)
Checking the restored functionality
After doing those steps, you're done. There's no need to restart CF.
Simply visit/refresh the "Debugging & Logging>Log Files" page of the CF Admin. You should see now see the few buttons that control the options to "view/search", "download", "delete" buttons that had been removed.
Reverting to the original functionality
If you want to revert back to the original folders (for the sake of security), use the backup you made in my step 3 above.
While you could just rename these "new" folders to something else, an argument could be made that if there are indeed important security concerns with these folders and the "older code" here, it would be wiser to instead remove the folder holding this "older code" that I am offering here, then replace it with those backups I had you make above.
Other CF log viewing mechanisms
Before wrapping up, I should note (as some may want to point out) that there are in fact other ways to view CF logs. Of course, one may be able to remote into (or ssh or map somehow into) the server and access the files in the CF logs folder.
As for Adobe's new VS Code-based version of CF Builder, I have not been able to find any such log file viewer in the UI though it's indicated on that extension intro page that it includes one. Perhaps it's coming.
Regardless, the log viewing features in either version of CF Builder would be based on an RDS connection existing and opened to the server, and that's definitely recommended against for production servers, so those may not serve as suitable alternatives to the CF Admin logviewer for many folks.
I was really torn whether to offer these folders, but SO many people are complaining online about needing to be able to view their logs that I felt it was important to show people how easily they could recover this functionality, if they're insistent to do so.
Here again is the zip with the folders (and a readme holding the text of this blog post).
