Sequence Diagram: Interactions with resources (DB, Network, Caches, etc)

I am currently making a behavior assessment of different software modules regarding access to DB, Network, amount of memory allocations, etc.

The main goal is to pick a main use case( let's say system initialization) and recognize the modules that are:

By assessing those, I could have an overview of the modules that need to be reworked in order to improve performance, delete redundant DB accesses, avoid CPU usage peaks, etc.

I found the sequence diagram a good candidate to represent the use cases behavior, but I am not sure how to depict their interaction with the above mentioned activities.

I could do something like shown in this picture, but that is an "invention" of tagging functions with colors. I not sure if it is too simplistic or childish (too many colors?).

enter image description here I wonder if there is any specific UML diagram to represent these kind of interactions.

Using SDs is probably the most appropriate approach here. You might consider timing diagrams in certain cases if you need to present timing constraints. However, SDs already have a way to show timing constraints which is quite powerful.

You should adorn your diagram with a comment telling that the length of the colored self-calls represent percentage of use or something like that (or just adding a title telling this). Using colors is perfect by the way.

As a side note: (the colored) self-calls are shown with a self-pointing arrow like this

enter image description here

but I'd guess your picture can be understood by anyone and you can see that as nitpicking. And most likely they are not real self-calls but just indicators. So that's fine too.

tl;dr Whatever transports the message is appropriate.
