With few steps I will show you how to update missing Urchin statistics, or just to update them from the web server access logs.

You must have at least certain knowledge where the access logs are, and what is the server configuration to update Urchin.

First login to your Urchin panel as administrator, and then go to ‘Configuration �" Urchin Profiles �" Log manager’.
There find the domain you want to update and click on ‘Edit’ (the one with the wrench icon).

It is very rare the Urchin server and the Web server to be on one and the same hardware machine.

In this case Urchin stats are updating from remote Web Server and we go to remote Urchin settings.
Check whether the remote settings, as well as the credentials and the logs path are correct.
In case they are not, correct them and click on update.

You can use the ‘Browse’ button to locate certain web server log file if you want to reprocess or update Urchin statistics for a particular time-frame.
It could happen the log file to be already logrotated on your web server, so you have to log in to it and (find, extract) make sure they are available on the server, on place where Urchin can find them remotely. Also if you have multiple files you want to process, you may use “*” instead a name of a file.

So, I presume that you have set the ‘Remote Log Source File’ correctly, and now we must rerun Urchin.

For that login to your Urchin server via SSH with Putty or other preferred SSH client, switch to your Urchin user, and change the current directory to Urchin binary (where the executables are).

It depends on your Urchin version, but in my case the available options are:

The command we need in this case is “-p = specify profile to process”.
To update Urchin stats write the command like that:

urchin@urchin.server ~$/bin urchin �"p yourdomain.com

This will rerun the statistics and will update them:

If there are errors ( I am afraid I cannot cover all of them) search through Internet for resolution. In most of the cases the web server log file is just corrupted and you cannot use it or it has to be edited to remove the ‘bad’ part from it.

Do not forget to change and update the Urchin remote settings back if you have changed the log file there.
