I have noticed that memory creeps up, but cannot establish where the problem is. Unfortunately, by the time it is realized by the end user there is a problem, the Pi needs to be restarted leaving no record (that I am aware of) for what the recent memory usage was, and which apps (of any kind) are using the most memory.
Can anyone tell me how to either access such a log, OR how to create one - either in Xojo or other means on the RPi?
Implemented this for a project, and it turned out that we did not need it, but it did provide some very useful information.
From the website:
Munin is a networked resource monitoring tool that can help analyze resource trends and “what just happened to kill our performance?” problems. It is designed to be very plug and play. A default installation provides a lot of graphs with almost no work.
