You can update your license file and configure the settings for the license connection quota usage the configuration file emqx.conf. After the configuration, you can run emqx ctl license reload in EMQX command line tool to reload the license.

license {
  key  =  "MjIwMTExCjAKMTAKRXZhbHVhdGlvbgpjb250YWN0QGVtcXguaW8KZGVmYXVsdAoyMDIzMDEwOQoxODI1CjEwMAo=.MEUCIG62t8W15g05f1cKx3tA3YgJoR0dmyHOPCdbUxBGxgKKAiEAhHKh8dUwhU+OxNEaOn8mgRDtiT3R8RZooqy6dEsOmDI="
  connection_low_watermark  =  "60%"
  connection_high_watermark  =  "80%"
}

Where,

• connection_low_watermark is to set a threshold below which license connection quota usage alarms are deactivated; default: "75%"
• connection_high_watermark is to set a threshold above which license connection quota usage alarms are activated; default: "80%"
