crude idea for log storage/retrieval
Posted: Wed Dec 04, 2019 6:48 pm
Hi all -
I need to start storing log messages. It would be nice if I could store ~1000 messages of up to ~100 characters each. I've already done all the work involved in routing ESP_LOG* though my own function, so now I just need a means of storing them. I was thinking of using a namespace in NVS, and store them as key value pairs. The keys would be like LOG_NNN, and I'd maintain a variable that denoted the last used value. Once I reached the limit (of 999) I'd start over, to emulate a crude ring buffer.
Before I dive into this, I just wanted to get a sense from people as to whether this idea was good/so-so/terrible. I don't think I will need to be terribly efficient (most of the time, there will just be one message every few minutes of operation, though there will be occasional bursts when a handful of messages might all come at (nearly) the same time.
Opinions? Thanks...
