Issue Let’s define the term Node State as: an indicator of the level of response required by an outage. If a node provides a business function to clients then we can say it’s in a Production state which implies OpenNMS should respond to outages in a timely manner. In most environments, the Production state is the most common state but it’s not [...]
Issue In a large scale OpenNMS deployment nodes need to be put into categories. Categories allow for inclusion or exclusion from reports, web pages, notifications, etc. Categories may relate to many different node attributes, such as who manages a node, node type, monitoring frequency, etc. OpenNMS provides no specific structure for categories and has several distinct ways of storing and managing categories: From the OpenNMS node page, you can click on Asset [...]

Creating and maintaining a large scale configuration with hundreds of nodes and thousands of services is daunting. If nodes are missing then you risk being unaware of an important outage. If you mistakenly monitor a node that will be taken [...]
