Help I have a few more questions besides the Log

[AppleCitron]

I am developing an application using Milo. I have some questions for you.

1. Logger problem
   The application must connect to several OPC servers. The application creates and operates multiple OpcUaClients. However, only one logger leaves logs. When a single process has multiple OpcUaClients, is there any way that each OpcUaClient can leave its own log separately?

          public class OpcUaClient implements UaClient {
          
              public static final String SDK_VERSION =
                  ManifestUtil.read("X-SDK-Version").orElse("dev");
          
              static {
                  Logger logger = LoggerFactory.getLogger(OpcUaClient.class);
                  logger.info("Java version: " + System.getProperty("java.version"));
                  logger.info("Eclipse Milo OPC UA Stack version: {}", Stack.VERSION);
                  logger.info("Eclipse Milo OPC UA Client SDK version: {}", SDK_VERSION);
              }
   

2. Is there any way to set the channel reconnection time?

      public static ChannelFsm newChannelFsm(UaStackClient client) {
              ChannelFsmConfig fsmConfig = ChannelFsmConfig.newBuilder()
                  .setLazy(false) // reconnect immediately
                  .setMaxIdleSeconds(0) // keep alive handled by SessionFsm
                  .setMaxReconnectDelaySeconds(16)
                  .setPersistent(true)
                  .setChannelActions(new ClientChannelActions(client))
                  .setExecutor(client.getConfig().getExecutor())
                  .setScheduler(client.getConfig().getScheduledExecutor())
                  .setLoggerName(CHANNEL_FSM_LOGGER_NAME)
                  .build();
      
              ChannelFsmFactory fsmFactory = new ChannelFsmFactory(fsmConfig);
      
              return fsmFactory.newChannelFsm();
          }
   

3. Is there any way to know the session status during Milo operation?

4. Is there any way to know if KeepAlive is working during Milo's operation?

[kevinherron]

is there any way that each OpcUaClient can leave its own log separately?

No, this is kind of just how Java logging works in general.

Is there any way to set the channel reconnection time?

Reconnection happens immediately and then exponentially backs off until it's ~16 seconds between attempts. It's not configurable right now - what would you change about it?

Is there any way to know the session status during Milo operation?

Add a SessionActivityListener that receives onSessionActive and onSessionInactive callbacks.

Is there any way to know if KeepAlive is working during Milo's operation?

No, but I can look at adding some kind of success/failure callback for this in the dev/1.0 branch. It's never been something I've had a need for in the past, but I supposed it could be useful.

Thank you for your response.

1. Are there any plans to change the log creation so that it can be generated using an ID value or without using a static variable?

2. Are there any plans to allow users to customize the maximum reconnect time?
