If you're getting a lot of installs from cache, an optional suggestion is to clear your pip cache so you know you're working with a fresh version install of the package and dependencies. But this is totally optional and only suggested if you're running into consitency issues.

To find your pip cache - pip3 cache dir

ex: rm -rf /Users/<user>/Library/Caches/pip

Class instantiation

When initializing our logger class, we have three parameters and one optional:

1. Logger_name :required string - this should be your app/job name
2. Level :optional string - this should be the level of logs you wish to be displayed to console. Ex: If set to INFO or DEBUG (with debug being incredibly granular) all log messages no matter the level will be logged. If set to CRITICAL, only critical messages will be logged.
3. App insights token :optional string- Your instrementation key only if you pass the connection string you will receive an exception.
4. Send_to_azure: optional boolean - defaulted to True. Sends your logs to Azure app insights if you have an instrumentation key initilized.

Method Parameters

example: logger.info('your message')

1. message any - the message you want to send to Azure app insights/logged in your app.
2. structured boolean - defaulted to True. When set to True your messages will structure your log with a default JSON structure which includes information to signify what job the logs came from, the severity and message. The JSON structure allows us to parse Splunk and Azure app insights logs with more clarity and granularity by formatting everything by a JSON key/value. To enable the JSON log structure in splunk, update your jobs deployments/{job}.yaml to use JSON via fluentbit.io/parser: json
