Thread: Standalone server with MediaCache S3 - Tuning

  1. #1

    Default Standalone server with MediaCache S3 - Tuning

    Hi,

    I would like some help to tuning my MediaCache Addon.

    How do I see the build of MediaCache that I use? It was released some update for mediacache this year or month? How do I update it if necessary?

    I use a standalone server with S3 and this setting attached.
    My server configs:
    Intel Xeon 3220-Quad Core 2.4GHz
    4 GB Ram
    500 GB total avaible space with RAID10
    1Gbps Network

    What changes should I do in the properties config for it to work better? How can I clear the cache without restarting the server wowza?

    Hi Carlos,

    You can find the build number in the version.txt file that came with the download.
    There have been some recent updates to MediaCache so you may want to download the latest version

    There is not a way to clear the whole cache without re-starting.

    You can instruct Wowza to purge an item from the cache the next time it is not being used:

    Default

    Additionally you can utilize JMX to request to purge an item:

    WowzaMediaServerPro->MediaCache->MediaCache

    There is an operation called flushItemFromCache which accepts a stream as a parameter.

    Default

    According to the settings of my server that I posted below, what changes should I do in the properties config of MediaCache to performance tuning it?

    Example:
    MediaCacheStore:
    <MaxSize>50G</MaxSize> ??
    <Level1FolderCount>16</Level1FolderCount> ??
    <Level2FolderCount>16</Level2FolderCount> ??
    <FileCount>1000</FileCount> ??
    <WriteRate>16M</WriteRate> ??
    <WriteRateMaxBucketSize>64M</WriteRateMaxBucketSize> ??
    <WriteRateFillFrequency>100</WriteRateFillFrequency> ??
    <MediaCacheSource> ??
    <Name>maxPoolSize</Name> ??
    <Value>25</Value> ??

    Thanks!

    On your Amazon source, you may want to increase the DefaultBlockSize to 1M - 2M to prevent frequent requests back to the source if resources become an issue etc. Otherwise it appears you have pretty standard default configuration. Are you experiencing any specific issues?

    Matt,

    Not yet, but I will be providing a stream account with 300 GB of videos (about 3000 files) hosted on Amazon S3 and I will make them available via MediaCache by my standalone wowza server. I'll have an average of 800 concurrent users, so I would tuning the settings of MediaCache to avoid problems.

    MediaCacheStore: <MaxSize>50G</MaxSize> - The default maxsize of MediaCache is 50GB, that means only 50 GB is cached on the server? By the size of my HD, I shouldn't increase this value to avoid a high volume of bandwidth between S3 and my standalone server?

    MediaCacheStore: <WriteRate>16M</WriteRate> / <WriteRateMaxBucketSize>64M</WriteRateMaxBucketSize> - I use RAID10 with 4 SATA II HDs, this default value on MediaCache config is appropriate for my HD?

    <MediaCacheSource>: <Name>maxPoolSize</Name><Value>25</Value> - This value is correct to the demand of concurrent users that I expect?

    Thanks!

    Carlos,

    I'm not sure how else to help with MediaCache tuning of server you have started yet. But I would suggest having the Wowza Dynamic Load Balancer set up and ready to add MediaCache servers, each also configured as Load Balancer Senders, because the real power of MediaCache is that it enables edge cluster for easy scaling. That way you don't have to sweat the limits of a single server, you can add quickly a server quickly if it starts to heat up.

    Richard,

    Thank you for your reply. I would like tune the MediaCache to reduce the bandwidth cost on S3 for standalone edge servers. How can I do this?

    Currently the cache is being cleaned very fast. By the size of my HD, the first change should I do is increase the maxsize, right?
    <MaxSize>50G</MaxSize> to <MaxSize>500G</MaxSize>

    Do I must configure mediacache also to retain content for the long as possible, right? How can I do this? If the cache is full, it automatically removes the old content to save new content?

    For these settings below, should I change them?
    <GCFrequency>10000</GCFrequency> ??
    <WriteRateMaxBucketSize>64M</WriteRateMaxBucketSize> ??
    <WriteRateFillFrequency>100</WriteRateFillFrequency> ??
    <Name>maxPoolSize</Name> <Value>25</Value> ??

    Thanks!

    The way to affect cost is to change how long MediaCache assets are retained, the /MediaCacheSource /MaxTimeToLive and /MinTimeToLive. And the /MediaCacheStore /MaxSize

    And to reload the cache on re-start so there is less fetching over the network.
