So I set up the VPN connectors between the internet gateways using the old legacy console. These connectors are shown in the java console under the gateway nodes (as object class VPNConnector).<br />
Since NetXMS 1.2.14 they have also an icon (but I don't know why with a questionmark on the icon) and they appears on Layer3-maps (that's fixed, thanks)</p>
<p dir="auto">So I see still 2 issues with VPN connectors:</p>
<ol>
<li>
<p dir="auto">Configuration:<br />
The VPN connectors are still not configurable in Java console (1.2.14), whether changes nor creation.</p>
</li>
<li>
<p dir="auto">Event Correlation:<br />
When a VPN tunnel goes down, we recieve from NetXMS one 'Node down' for the remote VPN gateway (=ok). But when the VPN tunnel goes up again, we allways get 'Node up' for every node on this remote site (=not ok). It seems the event correlation on 'down' is ok but not on 'up'.</p>
</li>
</ol>

Now there is a possibility to 'create' VPN connectors, but you can only specify a name of the connector and that's it. It's still not possible to configure the connector (peer node). In properties are only 'access control', 'comments', 'custom attributes' and 'status calculation'. So I still need the old console application.</p>
<p dir="auto">to point 2 (event correlation):<br />
The new parameter for SYS_NODE_UP is working as expected.</p>

<p dir="auto">Thank's for the fast help. Now it starts. Then I tested the new function with the new parameter of Event SYS_NODE_UP with a filter script ($1 != 1). Works exactly like expected! That will help me a lot! Now I revert to V1.2.14 again. For production I will wait for V1.2.15</p>

nxdbmgr -X upgrade? (that results in an endless loop)<br />
i stopped this and then: nxdbmgr batch script.sql (where I copied the two lines in)<br />
But netxmsd doesn't start</p>

<p dir="auto">I also like solution 1 more. I just implemented it - starting with 1.2.15 SYS_NODE_UP event will have parameter at index 1 which will be set to 1 if node is returning from "unreachable" state and 0 if from "down".</p>
<p dir="auto">Best regards,<br />

<p dir="auto">Sorry for the late reply.</p>
<p dir="auto">for 1:<br />
Ok so I hope everything for VPN connectors will be available in Java console in 1.2.15 and there is no need for the old console anymore.</p>
<p dir="auto">for 2:<br />
I can't say which solution is better (more powerfull, flexible and better integrated in the concept of NetXMS), but I tend to solution 1. Can you open this as a feature request for V1.2.15?</p>
<p dir="auto">Thanks</p>

<p dir="auto">currently node can have 3 states regarding connectivity (and so there are 3 events): down (event SYS_NODE_DOWN) - when server cannot contact the node and has no topology information for event correlation or it is really problem with that node; unreachable (SYS_NODE_UNREACHABLE) - when server knows that node cannot be contacted due to intermediate router/interface failure; and up (SYS_NODE_UP) - when node is reachable. So when node becomes unreachable, either SYS_NODE_DOWN or SYS_NODE_UNREACHABLE event is generated, depending on root cause. But when node became reachable again, SYS_NODE_UP being generated. I see two possible solutions - either add previous state indicator to SYS_NODE_UP event or create separate event for node returning from unreachable state - then you'll be able to distinguish between those two types of node up events.</p>
