Michel or Chris, could you provide some information on the reading and interpretation of the results of the SM command in the ISY Shell?

 

My current output is:

This displays the current usage of some of the memory used by ISY. Its primarily intended as a development tool for us to help in debugging problems.

Hi JAJ,

 

It would be very difficult to explain these numbers with the object using those memory blocks. In short, the first column is the size of memory block used (in bytes) and the rest is self explanatory.

 

 

With kind regards,

Michel

Thanks for the replies. Without giving much detail about each one, does this report give a good representation of the percentage of memory used within ISY? Ie. can it be used by the user to judge memory usage? For example, in the report above, it looks like roughly 50% is used.

Hi JAJ,

 

Yes. For instance, you have used 228 nodes (170 byte blocks) and, as far as memory is concerned, you can support more programs. The rest are objects that are dynamically allocated and deallocated and are there only for debugging purposes.

 

With kind regards,

Michel

Excellent! So the 170-byte block line is the one the user is interested in, to keep an eye on memory usage. Thanks!
