适用于

  • ThingWorx Platform 9.3 to 9.6
  • InfluxDB

说明

  • ThingWorx 平台重启期间 InfluxDB (Influx) 持久化提供程序无法启动
    数据未写入 InfluxDB
  • 如果初始连接尝试失败，InfluxDB 持久性提供程序不会重试数据库连接
  • 其他持久性提供程序（例如 PostgresPersistenceProviderPackage）上存在的重试参数在 InfluxPersistenceProviderPackage 或 Influx2PersistenceProviderPackage 上不存在
  • Influx Persistence Provider > Configuration 选项卡缺少以下重试参数
    • 获取重试次数
    • 获取重试延迟
  • 以下错误之一记录在位于<ThingworxStorage>\logs的 ThingWorx 日志中
    • 应用程序日志
