I started to make Log Analizer, today it on windows it similar to Alexey (https://github.com/AlexeyALeonov/success_rate)
But it has UI, and taking less RAM, and can make smaller proccessor utilization.
But i want add some aditional features, like trace some aditional Errors in logs.
Can everyone post their Errors from logs like DB mailforemed, that i can get needed fraze piece to search in log.
first virsion can be found here.
