[0.2.0] - 02.04.2021

Added - Major Update

Recently I came across some log-overflow problems, and they must be fixed, so I decided to make some changes in this middleware.
I will not delete some old args, despite some overlapping (remove_labels can be replaced with new custom_base_labels for example), - don't want to break API and functionality with this update.

  • Init parametercustom_base_labels - if you want change default labels to yours - pass them here. REWRITES DEFAULT LABLES. Args remove_labels WILL BE IGNORED.
    example - ['path','method'] - and you have metric, that contains only path and method labels.
  • Init parameter custom_base_headers - if you want change default headers to yours - pass them here. REWRITES DEFAULT HEADERS. Args additional_headers WILL BE IGNORED. If you use custom_base_labels, don't forget to pass headers in it, otherwise custom_base_headers will have no effect.
    example - ['content-type','x-api-client'] - and now you write only these two headers.
  • Init parameter aggregate_paths - if you have endpoints like /item/{id}, then, by default, your logs will quickly overflow, showing you huge amount of numbers, when, in fact, there is only one endpoint. So pass here list of endpoints path to aggregate by.
    example - ['/item/']
