I apologize if this information is vague, as I am fairly new to the openNMS world. But my problem is this. I have a few very small networks that I am monitoring through OpenNMS that is installed in a data center. These networks are linked by way of VPN tunnels. A couple times each day, a specific service on one node or another will go out for only a second and be resolved in that same second. I have checked the error logs and have nothing. Just wondering it this may be an issue within OpenNMS that something isn't happy, or if I need to be exploring other options.
