The last part should be: 24 Oct 2012 12:50:30 ProxyJMXTest is not reachable High 19s No 24 Oct 2012 12:49:41 ProxyJMXTest is not reachable High 49s No 24 Oct 2012 12:50:00 ProxyJMXTest is not reachable High 19s No 24 Oct 2012 12:49:11 ProxyJMXTest is not reachable High 49s No 24 Oct 2012 12:49:30 ProxyJMXTest is not reachable High 19s No 24 Oct 2012 12:48:41 ProxyJMXTest is not reachable High 49s No 24 Oct 2012 12:49:00 ProxyJMXTest is not reachable High 19s No 24 Oct 2012 11:29:41 ProxyJMXTest is not reachable OK High 1h 19m 19s No 24 Oct 2012 10:29:00 ProxyJMXTest is not reachable PROBLEM High 1h 41s No<<<<<Machine went off the network |

The number of items does not affect the problem from arising. I originally included that information because before further investigation I thought that may have contributed to the problem. With one item polled every 30 seconds there is still the trigger event going off: 24 Oct 2012 13:36:30 ProxyJMXTest is not reachable High 20s No 24 Oct 2012 13:35:40 ProxyJMXTest is not reachable High 50s No 24 Oct 2012 13:36:00 ProxyJMXTest is not reachable High 20s No 24 Oct 2012 13:35:10 ProxyJMXTest is not reachable High 50s No 24 Oct 2012 13:35:30 ProxyJMXTest is not reachable High 20s No 24 Oct 2012 13:34:40 ProxyJMXTest is not reachable High 50s No |

why send data every 30 seconds only ? default is one second... most likely proxy is unable to transmit all collected data quickly/timely enough, and it arrives in server with a delay. the timestamps you see for item values are assigned on the proxy, they are not indicating when server received the values. i'd suggest reducing the data sending interval to 1, 5 or even 10 seconds and seeing whether the problem goes away. |

Indeed that solves the problem. However, even when the rate is 30 seconds, it appears that the proxy transmits the data just fine. I've tested it with a single host monitored with a single item and the problem exists. |

is that a single host with single item on a single proxy, and the only thing monitored by a server ? |
