Debug logging for your instance

This section describes how to enable debug level logging in Bitbucket.

Enabling debug logging via the UI

To enable debug logging:

  1. Go to the Logging and Profiling.
  2. Select Enable debug logging.

Enabling debug logging on startup

To enable debug logging whenever Bitbucket. is started, edit the <Bitbucket home directory>/shared/bitbucket.properties file (if this file doesn't exist then you should create it) and add these two lines:

logging.logger.ROOT=DEBUG
logging.logger.com.atlassian.bitbucket=DEBUG

If your instance is earlier than version 3.2, the bitbucket.properties file is at the top level of your home directory.

Enabling debug logging at runtime

To enable debug logging for the root logger once Bitbucket. has been started, run these two commands in your terminal:

curl -u <ADMIN_USERNAME> -v -X PUT -d "" -H "Content-Type: application/json" <BASE_URL>/rest/api/latest/logs/rootLogger/debug
curl -u <ADMIN_USERNAME> -v -X PUT -d "" -H "Content-Type: application/json" <BASE_URL>/rest/api/latest/logs/logger/com.atlassian.bitbucket/debug

# e.g.
curl -u admin -v -X PUT -d "" -H "Content-Type: application/json" http://localhost:7990/rest/api/latest/logs/rootLogger/debug
curl -u admin -v -X PUT -d "" -H "Content-Type: application/json" http://localhost:7990/rest/api/latest/logs/logger/com.atlassian.bitbucket/debug


To enable debug logging for a specific logger, run this command in a terminal:

curl -u <ADMIN_USERNAME> -v -X PUT -d "" -H "Content-Type: application/json" <BASE_URL>/rest/api/latest/logs/logger/<LOGGER_NAME>/debug

# e.g. embedded Crowd debug log
curl -u admin -v -X PUT -d "" -H "Content-Type: application/json" http://localhost:7990/rest/api/latest/logs/logger/com.atlassian.crowd/debug
 
# e.g. LDAP debug log
curl -u admin -v -X PUT -d "" -H "Content-Type: application/json" http://localhost:7990/rest/api/latest/logs/logger/com.atlassian.crowd.directory.SpringLDAPConnector/DEBUG
# e.g. email debug log
curl -u admin -v -X PUT -d "" -H "Content-Type: application/json" http://localhost:7990/rest/api/latest/logs/logger/bitbucket.mail-log/debug

Profiling logging for your instance

This section describes how to enable profiling in Bitbucket. This log is essential when troubleshooting performance issues.

Enabling profiling logging via the UI

To enable profiling:

  1. Go to the Logging and Profiling.
  2. Select Enable profiling.

Debug logging for Git operations on the client

Atlassian Support might request debug logs for Git operations (on the client) when troubleshooting issues. You can enable debug logging on the Git client by setting the following variables. If you are using HTTP/S, remove the Authorization header from the output, as it contains your Basic-Auth information. Atlassian provides a set of scripts that simplify the collection of Git client debug information.

On Linux

Execute the following on the command line before executing the Git command:

export GIT_TRACE_PACKET=1
export GIT_TRACE=1 
export GIT_CURL_VERBOSE=1


To measure the length of time a command takes to complete, use the time utility/command prior to the actual git command. For example, to test a push to branch "master":

time git push origin master

On Windows

Execute the following on the command line before executing the Git command:

set GIT_TRACE_PACKET=1
set GIT_TRACE=1 
set GIT_CURL_VERBOSE=1

Setting GIT_CURL_VERBOSE is only useful for connections over HTTP/S since SSH doesn't use the libcurl library.

Debug logging for your Backup Client

Atlassian Support might request debug logs for the Backup client when troubleshooting issues.

To enable debug logging for the Backup client, add a file named logback.xml to your working directory (pwd) with the following content:

logback.xml
<included><logger name="com.atlassian.bitbucket" level="DEBUG"/></included>
