6.1. File structureΒΆ
The default encoding is utf-8. You can use a different encoding, like in:
<?xml version="1.0" encoding="ISO-8859-1"?>
Scenarios are enclosed into tsung tags:
<?xml version="1.0"?>
<!DOCTYPE tsung SYSTEM "/usr/share/tsung/tsung-1.0.dtd" [] >
<tsung loglevel="info">
...
</tsung>
If you add the attribute dumptraffic=”true”, all the traffic will be logged to a file.
Warning
this will considerably slow down Tsung, so use with care. It is useful for debugging purpose. You can use the attribute dumptraffic=”light” to dump only the first 44 bytes.
Since version 1.4.0, you have also a specific logging per protocol, using dumptraffic=”protocol”. It’s currently only implemented for HTTP: this will log all requests in a CSV file, with the following data:
#date;pid;id;http method;host;URL;HTTP status;size;duration;transaction;match;error;tag
Where:
field | description |
---|---|
date | timestamp at the end of the request (seconds since 1970-01-01 00:00:00 UTC) |
pid | erlang process id |
id | tsung user id |
host | server hostname |
url | URL (relative) |
HTTP | status HTTP reponse status (200, 304, etc.) |
size | reponse size (in bytes) |
duration | request duration (msec) |
transaction | name of the transaction (if any) this request was made in |
match | if a match is defined in the request: match|nomatch (last <match> if several are defined) |
error | name of http error (or empty) |
tag | tag name if the request was tagged; empty otherwise |
The loglevel can also have a great impact on performance: For high load, warning is recommended.
Possible values are:
- emergency
- critical
- error
- warning
- notice (default)
- info
- debug
For REALLY verbose logging, recompile tsung with make debug and set loglevel to debug.
