Caution

This feature is still in Beta testing and hence may undergo further changes. Therefore, you are advised NOT to use this in any production environment.

This may also, in future, replace Business Services.

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.

Future Development

RBAC support will be added for Enterprise Services soon.

Enabling Enterprise Services

To enable Enterprise Services –

Add the following code to opcommon.json

"beta":{
"opcharts_enterprise_services": "true"
   },

Execute the following commands

sudo/usr/local/omk/bin/patch_config.exe /usr/local/omk/conf/opCommon.j

son /beta/opcharts_enterprise_services=true

Restart the omkd daemon
```
sudoservice omkd restart
```

Service Metrics

Node Status: The Node Status is calculated from the status events for the Node. It aggregates the status event levels and presents an average of the same.

If any Node is unreachable, the Enterprise Service is marked Unreachable. If a Node is Reachable, but it is not at its optimal level/health, the Service is marked Degraded.

Interface Status: The Interface status is calculated by aggregating all the Interface-related status levels and averaging them out.

The Down Metrics shows all the Interfaces marked as Interface Down. It stores a count of such Interfaces.

If any Interface is marked Interface Down, the Enterprise Service is marked Unreachable.

Monitored Services: The Service Status shows the aggregate of all service inventory tagged with the Enterprise Service name.

If any monitored Service is marked Down, then the Enterprise Service is marked Unreachable.

Overall Status: The Overall Status can be UP , DEGRADED , or DOWN

The overall state of the Enterprise Service is calculated from the worst state of each of the services.

Monitored Services	Nodes	Interfaces
Services Fatal	Nodes Unreachable	Interfaces Down
Services Degraded	Nodes Degraded	Interfaces Up
Services Up	Node Up
Status	Status	Status

Enterprise Service Rules

Enterprise service rules calculate how each group of entities control the status of the service.

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 Status Panels/Tables

After creating a new Enterprise Service on the opCharts, you can add Interfaces, Nodes and Monitored Services status panels/tables to it.

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, a node panel for the selected node should now be displayed.

Add a Monitored Service

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.
