Starting with version 10.2, ILA Importer allows reports localization via the STRING tags.
You can change the following VALUE parameters in the <install_directory\loganalyzer\rpt-lang.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<LANGUAGE>
<STRINGS>
<STRING ID="MailSubject" VALUE="LogAnalyzer import statistics for server" />
<STRING ID="MailText" VALUE="Loganalyzer import statistics for server" />
<STRING ID="ReportTitle" VALUE="<H1>Loganalyzer import statistics for server %%SERVER_ID%% </H1> (processed at %%EXEC_TIME%% %%EXEC_DATE%%) <BR>" />
<STRING ID="ReportDateFormat" VALUE="dd/mm/yyyy" />
</STRINGS>
</LANGUAGE>
NOTE: When changing anything, you still have to obey xml syntax rules.
