Systems Center Operations Manager (SCOM) monitors both availability (events) and performance (capacity and utilization) for the datacenter and cloud.
After researching how to integrate SCOM events with ManageIQ I have documented 3 different approaches in order of (my) preference. Please chime in with any feedback you have.
Option 1) SCOM Connector
A connector is a custom service or program that enables Operations Manager to communicate bidirectionally with third party systems. See http://msdn.microsoft.com/en-us/library/hh328935.aspx
A ManageIQ connector would be written in Powershell using the Operations Manager Connector Framework (OMCF) SDK. Two Powershell scripts are required.
i. A setup script – to create a connector in SCOM with a subscription specific to ManageIQ. This subscription would have a polling interval setting and a criteria setting.
ii. A second script would be executed within ManageIQ and would read the events gathered by the connector for normalization by ManageIQ.
- Lightweight solution
- High performance
- SCOM, not ManageIQ, takes care of the polling and filtering and makes the events available after
- We can leverage the same connector for importing capacity & utilization data in the near future.
- Requires editing customers’ SCOM application by inserting the connector to ManageIQ. (Maybe this is a potential problem for some customers.)
Option 2) Powershell cmdlet
SCOM exposes events through a simple cmdlet (Get-SCOMAlert)
This could be polled every X minutes from ManageIQ filtering on the event creation time and resolution state.
- Lightweight solution
- A broker to SCOM will have to be developed otherwise a new connection
will have to be opened and then closed each time the cmdlet runs.
Note – Right now SCOM cmdlets can be run directly from the VMM server
but not remotely using WinRM via VMM. If I can get this to work one
broker can be created to VMM for both ems refreshes and importing
- SCOM has no Powershell cmdlet that returns performance data
so this option cannot be reused for gathering capacity & utilization
- Consideration will have to be given to the performance
implications of filtering each event on resolution state and creation
Option 3) Orchestrator Runbook.
System Center 2012 Orchestrator is a workflow automation tool that allows integration between heterogeneous environments. One use case is the transfer data (such as events) between them.
A run book can be designed in Orchestrator for ManageIQ that queries the SCOM database for events in one runbook activity and exports them into a parsable format for ManageIQ to read in a second activity.
- It will work.
- Customers will have to deploy System Center Orchestrator if they have not already done so.
In my opinion Orchestrator is better suited to more complex integrations such as a ticketing system (eg Remedy)
