You can access the different types of log files on Umbraco Cloud or through . You have access to different types of logs:
Umbraco logs
Deploy logs
Environment logs
Site Extension logs
IIS logs
Go to your project and click on the arrow next to the environment name.
Click Logs to view the log details.
It is possible that a deployment failed so it is not the active deployment at the moment, there could be valuable information in the logs of this deployment. You can find out what the last attempted deploy was by going to your Kudu URL and adding /api/deployments to the URL (so for example https://stage-mysite.scm.s1.umbraco.io/api/deployments. This will give you some JSON data and the first entry here is the newest attempted deployment. You can also find some information in ~/site/wwwroot/umbraco/Deploy if there are for example extraction errors.
Whenever you push between environments or when you deploy using the Umbraco Cloud portal, you're deploying your site using Git. This works as follows: you commit changes to Git and push them to development, these changes is then stored in the site > repository folder. Then the state of the newest commit gets copied into the wwwroot folder, which is where your website lives.
When you're in Kudu, you can go up to the site folder and then the deployments folder. The active file has the identifier of the currently active deployment in it. If you go into the folder that has the same name as that identifier you can see a few files: log.log, manifest and status.xml.
status.xml shows you detailed information of which commit was deployed to the wwwroot folder
manifest is used to track which files are in the currently active deployment so that additions, renames and deletions, can be detected for the next deploy (this is an internal file which you should not touch)
log.log shows you the same output you will have seen when pushing your changes using Git, it will show you what happened during the push and if any errors occurred. This file is especially useful when trying to find errors for deploys using the portal (for example, from dev > live or from dev > staging > live). Even though the last line may end with "Deployment successful" it is possible that there were errors or suspicious messages before that so make sure to give them a read.
On Cloud environments, all errors are logged to a database table in the portal under each environment. If you leave too many unread log messages it can cause timeouts when you go to see your errors.
If you want to delete logs from one of your environments' log viewers then you will have to connect to the environment DB and run the following query:
This will delete 90% of the oldest logs that are unread and leave you with 10% of the newest ones. It is up to you to decide how many % of logs you want to delete.
It is possible to enable IIS Logging on each of your Umbraco Cloud environments. There is a rolling size limit on the log files of 100 MB. This means that once the limit is reached, the oldest log files will be overwritten by new ones.
You can enable the logging from the Advanced menu found under Settings in the project overview for the project. The logs will be accessible from KUDU in C:\home\LogFiles\http.
After enabling IIS logging for the environment, the site will have to restart.
To access logs through Kudu, see article.
Umbraco logs on Cloud work almost the same as on a , they are still found in the ~/site/wwwroot/umbraco/Logs/ folder. Umbraco Deploy also writes to the standard log files with events and errors. If there is an extraction error and you can't find any issues in your Umbraco log, try the Deploy log listed below.
Since the errors are stored in your database, it is possible to clean them up. To do this, start by for the environment where you want to run the cleanup.
