What’s New in This Release

Introduction

New Features

Agent Connections Rate-Limiting

In some environments, the control center agent can inadvertently create an excessive load by losing connection and reconnecting to Control Center multiple times a minute. With Control Center 2023.3.1, you can limit the amount of reconnect attempts allowed within a timeframe. If the limit is exceeded, the agent will be banned from Control Center for the specified duration.

You can control the rate limiting by using the following parameters:

  • control.rate-limit:reconnectRateLimitCount configures the number of reconnect attemts allowed within the specified time period. Default value is 5.

  • control.rate-limit:reconnectRateLimitPeriod configures the time period for rate limiting. Default value is 1m.

  • control.rate-limit:reconnectBanDuration configures the duration for which additional reconnect attempts will be ignored. Default value is 5m.
