Maintaining an Avid Interplay System – The VERY Basics


For an Avid Interplay environment it is important to establish routine checks. For larger systems these should be performed daily but for smaller houses a simple check once a week should be enough to keep tabs on things. I would also strongly recommend email alerts where possible to help establish critical issues as and when they happen (failed RAID sets and failed ISBs on ISIS systems for example).

The VERY Basics
Avid Interplay is a Production Asset Management system –PAM, that is designed to interact with and manage media held on an Avid shared storage system. Every Interplay environment has a number of Core components that should be monitored.

1.       ISIS (or NEXIS) Shared Storage
2.       Interplay Engine.
3.       Media Indexer.
4.       Look Up Server

Depending upon your environment it may well be that you have a number of these core Interplay Servers which offers resilience through redundancy and load balancing. All other servers that then go around this will add functionality, such as Transcoding, Consolidating and Delivery servers. Should these ‘edge’ devices fail then that specific process, ‘Transcoding’ for example, will be lost but the overall systems function will remain.
Should however the Interplay Engine, Media Indexer or Look Up Server fail then the entire system will grind to a halt! This is obviously something to be avoided.

As an engineer you will be =expected to maintain the system, but it’s better to have checks and monitoring in place and catch issue before they become potential disasters. So what are the basics we should be checking for on a simple system, and even complex ones?

These first set of checks are with reference to a simple ‘single instance’ of the core systems I described earlier. In a later post I will discuss the needs of a more complex system with multiple redundant servers. Let’s look at an example system that is made up of an ISIS 5500 with a simple small Interplay system made up of a single Interplay Engine, Media Indexer and Look Up Server.

Grouping the test via server here is a step by step guide for my once a week checks.

The ISIS 5500
  1. Log into the System Director and open the System Director’s Control Panel.
  2. Indicators in the System Director Status should ALL be green.
  3. If the System Status is not green, check the Windows Event logs on the System Director.
  4. Login to ISIS web interface: http:\\<systemdirectorname>
  5. Check the Storage Manager/Elements Status.  All Storage Managers and Storage Elements should be green, investigate any errors.
  6. Check the Status side bar for messages and history of incidents, clear the event notifications if there are any so as to stop you investigating old issues that have already been addressed.
  7. Check that the Avid ISIS Workspaces have “Free Space” available is sufficient.
  8. Check that your total system used space is below 85%. (for optimum performance)
  9. Check the system event logs on the System Director and additional Engines (if applicable) for recent error events.


Avid Interplay Production Engine – Single Engine
  1. Check AVDeletelogs for errors returned in the logs. Address issues with your Media Manager or investigate further. These logs can be accessed from a web browser by going to http://<yourmachinesname or IP address>/Logs/Engine/Machines/ (see below)
  2. Check Interplay Database Backup. If you haven’t established a backup of your database then do so now. Make sure it is a complete back up and happens at a time when the Interplay is under light load (2am for example)
  3. Verify scheduled daily “Backup” is complete onto your nominated location. The default for the backup will be the internal drive of your server, usually D:\WorkGroup_Databases\AvidWG\_Backup

Avid Interplay Media Indexer and Look Up Server.
Run the Avid Health Monitor from any client running Avid Service Framework. This is a tool that monitors the Interplay Framework that binds all the systems together within Interplay.
  1. If you have a physical device per service then verify that all your “Hosts” are online in “Hosts” view. If you have a single server running all the services such as the ‘Production Bundle’ offered by Avid then you will only have a single server listed here and the workstations then use the system. Open the arrow to ther side of the servber to see all the services that are running
  2. Address any issues listed in red in Health Monitor.
  3. Verify all “Processes” are running and healthy in “Processes” View. Look for the Red Cross for areas to be addressed first. The Yellow exclamation mark is a warning and my well be not a major issue.
  4. Under the Avid Interplay Media Indexer Process / Current Process Information, check Memory and CPU usage. If memory falls below 10% the MI will stop indexing files.
  5. Under the Avid Lookup Serve check the statuses show all green. Investigate as needed

UPDATE:
Avid changed the way Media Indexers worked in the 3.5 release of the product (3.7 is the most current as I write) These later versions no longer need the Avid Service Framework and so maintaining these is now different. Use the Avid Guide HERE to get more information about working with Media Indexers 3.5 and higher.


Extras
All all servers it’s also worth noting how long a Process or Server has been running for. This can be seen within all process under the Current Process Information. I personally like to keep the Running time to below 1000 Hrs on lightly used systems. 
The example below shows a running time of 425 Hours on a lightly used Media Indexer.


This is by no means an exhaust list of what you need to do and nor does it outline your needs as an engineer for how to address the issues found. 
I'm offering this list purely as a starting point to help you look in the right places to keep tabs on your systems needs and tweek over the top of this little list more tests that are appropriate to your sites needs.
Avid also publishes a Interplay Best Practices guide that outlines some check and what needs to be done to maintain a system. I would strongly recommend that you download the guide and read through it to establish what is and is not relevant to your site.

For more reading download the detailed guides for Interplay and get yourself on an Avid Interplay course!

Hope this helped
