Downloading AEM logs without accessing the filesystem via System Diagnosis Page Download shows empty file

[maryani]

I tried login with Admin credentials and tried to download logs from below URL,

System Diagnosis Page Download a system status ZIP export from the system diagnosis page: https://localhost:4502/libs/granite/operations/content/diagnosis.html (select Download Status ZIP).

but the size of logs file is showing more than 100mb but the downloaded file is empty and error while opening the granite_status.zip file, Please let me know if there anyway to download logs

Hi @maryani 

If you have access to system/console you can also download logs as zip from the below path

http://localhost:4502/system/console/status-slinglogs

Also on the diagnosis page can you try checking the thread dump alone and see if that is working 

[maryani]

If I dont have access to system/console, I tried On Diagnosis page , empty file is getting downloaded. Any thoughts on it?

[sherinregi]

@maryani  from what you have posted initially the zip is corrupted or it doesn't have any content. the 100mb which was showing on the dashboard is the size same for the downloaded zip also ?

can you confirm if the download was successful on the browser pane

[maryani]

on the dashboard it is showing 100MB but the downloaded file from the browser is just 900 KB, even after downloading the file, the file does'nt open up

Can you please validate across multiple 6.5 servers? 

I am using AEM Cloud SDK. Download of log files is no longer available there.

@maryani 

Can you  look for the below line in error.log files and see if you are getting any error.

GET /libs/settings/granite/operations/diagnosis/granite_status.zip

When I tested I could see one indexing/traversing issue on one of our servers, so wanted to check that as well in your case.

[maryani]

Yeah looks like it is same for me traversing

GET /libs/settings/granite/operations/diagnosis/granite_status.zip HTTP/1.1]

What can we do here?

Any thoughts here . I tried on a vanilla instance the log zip size as 2mb and was able to download the same,

but looks like when the size is more below exception is thrown.

This being one of the OOTB features what is actually getting queried here and any indexing possibility 

[aanchal-sikka]

Hello @sherinregi 

We should be able to capture the logs and create index.

Steps to capture query logs are here: https://aemtreasury.wordpress.com/2015/11/13/how-to-enable-logging-of-aem-query/

Also, we should raise a support ticket to inform Adobe about the same. 

@maryani 

- Which AEM version are you using ?

- Can you possible use system console for logs? Or use ftp tool to download logs from server? Authors generally don't access logs. Its for tech team.

[aanchal-sikka]

Hello @maryani 

For local AEM instance:

- you can access all logs from crx-quickstart/logs folder

For AEM server:

Sling > Log Support

- Go to http://localhost:4503/system/console/slinglog Or Sling > Log Support

- Click any of the links, here the links will open like http://localhost:4503/system/console/slinglog/tailer.txt?tail=10000&grep=*&name=%2Flogs%2Ferror.log . You can modify:

• tail value to get recent logs
• grep value to get lines with specific text

Status > Log files

This one @sherinregi  has already explained
