Atlassian Stash access log parser

The log parser parses and aggregates the access logs of the Atlassian Stash web application.


Download the pre-built binaries for your platform from:

The logparser binary supports multiple commands and accepts one or more logfiles as arguments (either in uncompressed or compressed (bzip2) form).


$> logparser gitOperations ./path/to/atlassian-stash-access-2012-09-12*.log

Executing logparser will show the help with a list of supported commands.

The logparser will parse, analyze and aggregate the log files and prints the aggregated records to STDOUT.

E.g. for the gitOperations command that shows the number of git operations per hour, the output will look like this:

[922] λ > logparser gitOperations atlassian-stash-access-2012-*.log.bz2
2012-08-22 18|2|0|13|0|733|0|0|0|0|0|2|0|13|0|733
2012-08-22 19|3|24|74|0|1660|0|0|0|0|0|3|24|74|0|1660
2012-08-22 20|2|33|119|0|1369|0|0|0|0|0|2|33|119|0|1369
2012-08-22 21|1|12|49|0|1514|0|0|0|0|0|1|12|49|0|1514

The fields are | separated. The first column usually contains a date field (using a 60 minute granularity). The format of the remaining columns depends on the command that is being used.

The first line of the output is a column name header prepended by a '#'.

The output can be used to generate graphs, either using the provided gnuplot scripts or by using the Confluence chart macro.

The shows how to run the logparser, pipe the output into data files and generate gnuplot graphics as PNG images.

$> ./ '/data/stash-access-log/atlassian-stash-access-2012-09*.log*'

Access log format


  • Ip address. If there are multiple addresses, the first address is the 'real' ip address and the remainder the IPs of intermediary proxies

  • Request id of the format: i6x3112x1, where:
    • i = start of the request, o = end of the request
    • 6 = minute in day => 0:00:06
    • x = separator
    • 3112 = request number since last restart
    • x = separator
    • 1 = number of requests being serviced concurrently at the start of the request
  • Username: only available on the end of the request
  • Date/Time
  • Action:
    • for HTTP requests: "<http-method> <request-url> <http-version>"
    • for SSH commands: the ssh command-line
  • Request details:
    • for HTTP: "<referrer-url>" "<user-agent>"
    • for SSH: -
  • Labels: used in the application to add 'classifications' to requests. Currently supported:
    • type of hosting request: push | fetch | clone | shallow clone | refs
    • clone cache: cache:hit | cache:miss
  • Response time in millis
  • Session-id
