Overview

opCharts enables you to build dynamic interactive charts and targeted custom dashboards for single-pane-of-glass views into your NMIS data. It increases your network visibility and accelerates root cause discovery by combining multiple data sets on its adaptable graphical interface.

You can create one such dashboard to monitor Enterprise Services too, which allows you to view Interface and Node status panels on a single page.  You can also group any related Interfaces/Nodes together to view them all at one location. Further, the MSP authorization system supports the Enterprise Services when added as a dashboard component. 

Enterprise Service Metrics

• Nodes State: If any Node is unreachable, the Nodes State is marked Down. If any Node is degraded, the Nodes State is marked Degraded, otherwise it is Normal.
• Interfaces State: If any Interface is marked Down, the Interfaces State is marked Down, otherwise it is Normal.
• Services State: If any Monitored Service is marked Down, then the Services State is marked Down. If any Monitored Service is degraded, the Services State is marked Degraded, otherwise it is Normal.

• Overall State: The Overall State can be ,  , or
  The Overall State of the Enterprise Service is calculated from the worst of the Nodes State, Interfaces State and Services State, where Up is best and Down is worst.
  So if each State is Normal, the Overall State will be Normal, but if any State is Down the Overall State will be Down, or if the States are Normal and Degraded then the Overall State will be Degraded.

• Node Status: The Node Status is calculated from the status events for the Nodes. It aggregates the status event levels and presents an average of 0% to 100%.
• Interface Status: The Interface Status is calculated by aggregating all the Interface-related status event levels and averaging them out 0% to 100%.
• Service Status: The Service Status shows the average status event level of all Monitored Services for the Enterprise Service 0% to 100%.

Enterprise Service Rules

Enterprise Service rules calculate how each group of entities control the status of the Enterprise Service.  The Enterprise Service rules are defined in /usr/local/omk/conf/ES_Rules.json

The rules set out levels on how each component should be degraded, based on the status level. It is set as an array of Level Type and Level.

For example, Normal - 100, Degraded – 90 would mean, a status of 99 would be Reachable but a status of 89 would be Degraded.

You can use this to tune the alerts. For example, you can configure a proactive enterprise alert for any service if any Level Type is not Normal.

Adding Nodes, Interfaces and Monitored Services

After creating a new Enterprise Service on the opCharts, you can add Nodes, Interfaces and Monitored Services status to it. At the top of the Enterprise Service page you will see a row of buttons for each option:

Click on one of the options, and the page for that option will load. Click the '+' icon to add a Node.

Add an Interface

To add a new interface, press the "+" icon in the Interfaces section as shown in the screen shot above.  Enter or select the node name, select the interface index/name and press "Add".

Add a Node

Adding a Node is similar, press the "+" icon in the Nodes section.  Enter the node name and press the "Add" button, and the node will be added to Enterprise Service.

Add a Monitored Service

In opCharts 4.8.1 and newer you can now add Nodes, Interfaces and Monitored Services directly to an Enterprise Service from their relevant views.

Choose the items that you want added to an Enterprise Service using opCharts' advanced filtering capabilities, then to the left click on the checkbox for that item/s. You will notice a new button become visible, click this and then click on 'Enterprise Service'. You can then choose the Enterprise Service to add to.

Remove an Interface, Node or Service

To remove either, press the "x" icon near the top right of the panel and it will be removed from the document.  Save the document to accept your changes.

Repair RBAC for an Enterprise Service

We changed how an Enterprise Service is referenced in the database with opCharts-4.5.0 and this causes issues with RBAC (portal users) for Enterprise Services created before 4.5.0.

Easy method, delete the Enterprise Service and recreate with the same name, the nodes, interfaces and services will still be attached to the Enterprise Service.

You will need to add the roles you had before.
