From 8efe4bfc2ed7086e9fdf4812297e6525f955f6ac Mon Sep 17 00:00:00 2001 From: Justin Clark-Casey (justincc) Date: Mon, 29 Jul 2013 23:18:29 +0100 Subject: Make "abnormal thread terminations" into "ClientLogoutsDueToNoReceives" and add this to the StatsManager This reflects the actual use of this stat - it hasn't recorded general exceptions for some time. Make the sim extra stats collector draw the data from the stats manager rather than maintaing this data itself. --- .../Region/ClientStack/Linden/UDP/LLUDPServer.cs | 26 +++++++++++++++++----- 1 file changed, 21 insertions(+), 5 deletions(-) (limited to 'OpenSim/Region/ClientStack/Linden') diff --git a/OpenSim/Region/ClientStack/Linden/UDP/LLUDPServer.cs b/OpenSim/Region/ClientStack/Linden/UDP/LLUDPServer.cs index 25e10be..9e6a401 100644 --- a/OpenSim/Region/ClientStack/Linden/UDP/LLUDPServer.cs +++ b/OpenSim/Region/ClientStack/Linden/UDP/LLUDPServer.cs @@ -69,9 +69,22 @@ namespace OpenSim.Region.ClientStack.LindenUDP StatsManager.RegisterStat( new Stat( + "ClientLogoutsDueToNoReceives", + "Number of times a client has been logged out because no packets were received before the timeout.", + "", + "", + "clientstack", + scene.Name, + StatType.Pull, + MeasuresOfInterest.None, + stat => stat.Value = m_udpServer.ClientLogoutsDueToNoReceives, + StatVerbosity.Debug)); + + StatsManager.RegisterStat( + new Stat( "IncomingUDPReceivesCount", "Number of UDP receives performed", - "Number of UDP receives performed", + "", "", "clientstack", scene.Name, @@ -84,7 +97,7 @@ namespace OpenSim.Region.ClientStack.LindenUDP new Stat( "IncomingPacketsProcessedCount", "Number of inbound LL protocol packets processed", - "Number of inbound LL protocol packets processed", + "", "", "clientstack", scene.Name, @@ -97,7 +110,7 @@ namespace OpenSim.Region.ClientStack.LindenUDP new Stat( "OutgoingUDPSendsCount", "Number of UDP sends performed", - "Number of UDP sends performed", + "", "", "clientstack", scene.Name, @@ -149,6 +162,9 @@ namespace OpenSim.Region.ClientStack.LindenUDP /// Maximum transmission unit, or UDP packet size, for the LLUDP protocol public const int MTU = 1400; + /// Number of forced client logouts due to no receipt of packets before timeout. + public int ClientLogoutsDueToNoReceives { get; private set; } + /// /// Default packet debug level given to new clients /// @@ -1037,7 +1053,7 @@ namespace OpenSim.Region.ClientStack.LindenUDP timeoutTicks = m_pausedAckTimeout; if (client.IsActive && - (Environment.TickCount & Int32.MaxValue) - udpClient.TickLastPacketReceived > timeoutTicks) + (Environment.TickCount & Int32.MaxValue) - udpClient.TickLastPacketReceived > -1) { // We must set IsActive synchronously so that we can stop the packet loop reinvoking this method, even // though it's set later on by LLClientView.Close() @@ -1778,7 +1794,7 @@ namespace OpenSim.Region.ClientStack.LindenUDP "[LLUDPSERVER]: Ack timeout, disconnecting {0} agent for {1} in {2}", client.SceneAgent.IsChildAgent ?
