Here's how to manage and resolve the log size issues you are facing with your QuantConnect algorithm:

1. Understand Log Quotas:

   • QuantConnect imposes daily log quotas depending on your organization tier. On a free tier, you're limited to 10KB of logs per day for your account.

2. Reducing Log Output:

   • Limit the frequency and the verbosity of your log messages. Consider using conditional logging to ensure only necessary information is logged, and aggregate similar or repeated log entries to minimize log lines.
   • You can add timestamps to log messages to bypass any rate limits on duplicate content if you're seeing a high rate of duplicated logs.

3. Log Rotation:

   • QuantConnect manages log files with quotas. Logs from old sessions are cleared as necessary to remain within provided limits. Check your Logs tab in the QuantConnect platform to see how logs are stored and when they are cleared.
   • If you need fresher space and see build-ups of old logs, manually downloading and deleting older logs through the QuantConnect UI might help manage space better.

4. API Functionality:

   • You can utilize the logging management class Log to handle and manage your log outputs. However, ensure that logging mechanisms aren't creating unnecessary overhead.

Implementing these strategies will help prevent your algorithm from crashing due to log-related space issues. If the problem persists and affects your operations significantly, consider upgrading your QuantConnect subscription for higher log quotas or reach out to their support for more tailored solutions.

Hi Mia,
I'm using a Researcher tier and the issue happens on live node. I don't see in UI option to delete logs, just to download.
