How to test:¶

In class.t3lib_utility_monitor.php modify line 45:

if ($peakUsage / $memoryLimit >= 0.9) {

Change 0.9 to a low number such as 0.1; this will trigger the report on virtually each frontend page request.
See the Reports module for the resulting warning.

I saw this in 6.1. I did not find anything about how this is measured, the highest memory usage in the last hour or just at the time I run the install tool? Thanks for your explanation.

Hi Bernhard,

This issue tracker is meant for bug reports. For questions you can use the mailing lists / newsgroups / forum at typo3.org.

To answer your question: at the end of every frontend request the peak memory usage as measured by PHP is compared with the memory limit that is configured. If it exceeds 90% of that limit the memory usage, the date/time of the event and the requested URL are stored for later use by the Reports module. If this happens there is an option in the Reports module to remove the stored data.
With this data the administrator can investigate why the memory usage was so high and possibly take appropriate action (fix the problem, raise the memory limit).
