opCharts enables you to schedule NMIS outages and add multiple Nodes or Interfaces, or a combination of both, to a single outage event. You can also schedule a one-time outage or a recurring event for the required Node or Interface on the opCharts page. 

This document describes how you can schedule an outage using opCharts 4 and above.

Creating a Scheduled Outage

1. To schedule an outage on the opCharts page, from the menu, click Views > Scheduled Outages. 
   
2. On the Outages page that opens, click New Outage. 
   
3. Add a Description for the outage.
4. Specify a Change ID for easy identification of the outage event.

5. You can schedule a one-time outage or a recurring event under Frequency.

   By default, NMIS collects the performance data during every outage event. You may choose to discard it by selecting the Discard Performance Data check box. 

6. Under Outage Window, specify the Start and End time for the outage.

   Click the Common Time Formats link to know more about the time formats supported by Opmantek applications for parsing the start and end times.

   

7. Under Node Selection, choose the Selector Type - the type of device this outage is being configured for - Node or Element.
   • In case of a Node, choose the Node Property.
     • Select or enter the required Values. You can enter multiple Node Values (separated by commas) for the Property chosen.
       
   • In case of an Element, search for and select the Node.
   • From Element Section you can either select Interface or Other 
     • For Interface :
       • From the Interface / Regex drop-down list, select the elements - Interface or Interface Regex. 
         • In case of Interface, select the required element from drop-down(ex: Vlan1)
         • In case of Interface Regex, enter a valid regex pattern (ex: vlan* or ^Vlan.*?$)
     • For Other :
       • From the Type drop-down list, select either String or Regex
         • In case of string, Enter the valid string for that selected node under Value
         • In case of Regex, enter a valid regex pattern (ex: vlan* or ^Vlan.*?$)
8. Click the Add new selector button to add another Node or Element to the same Scheduled Outage. 
9. Click Save and Back to finish scheduling the outage.

Purging of Scheduled Outages

Once a scheduled outage in opCharts has lapsed, it will clear from the list as per the NMIS configuration.
