This helps a lot, thanks Shannon!

So if I read it right, the event is already getting distributed across the servers, I just need to catch it and trigger the examine update ?

I did see what looked like the media ids firing when I grabbed a Wireshark dump between the servers, so that would make sense.

yup so long as you are using a version later than 6.1.1

I'm on 6.1.5 so that should work nicely!

Thanks for your help, will let you know how I go.

I'm a bit late to the party, but don't hesitate to let us know if you need any more help on this.

Thanks Mads, yes, Shannon's pointers did the trick.

That's awesome! :)
Just remember to mark as answer then :)

Cheers

Yup, would be good to have this marked as 'answered'

Damian, running into the exact same issue. Any chance you can post the code you ended up with? Thanks!

For anyone else who needs it this is what I came up with. Seems to be working.

 void DMagEventHandler_CacheUpdated(MediaCacheRefresher sender, CacheRefresherEventArgs e)
    {
        var o = DeserializeFromJsonPayload((string)e.MessageObject);
        if (o.Any())
        {
            o.ForEach(a => IndexMedia(ApplicationContext.Current.Services.MediaService.GetById(a.Id)));
        }
    }
    private static JsonPayload[] DeserializeFromJsonPayload(string json)
    {
        var serializer = new JavaScriptSerializer();
        var jsonObject = serializer.Deserialize<JsonPayload[]>(json);
        return jsonObject;
    }
    private class JsonPayload
    {
        public Guid UniqueId { get; set; }
        public int Id { get; set; }
    }
    private static void IndexMedia(IMedia sender)
    {
        ExamineManager.Instance.ReIndexNode(
            sender.ToXml(), "media",
            ExamineManager.Instance.IndexProviderCollection.OfType<BaseUmbracoIndexer>().Where(x => x.EnableDefaultEventHandler));
    }

Sorry guys, was having a break from internets!

Reply marked, glad you got it working Randy. 

Hi, i can't implement a class from CacheRefresherBase to hook ; OnCacheUpdated because i get this error:

ERROR Umbraco.Core.Sync.DefaultServerMessenger - [Thread 102] Error refreshing a node in the distributed list System.Web.Services.Protocols.SoapException: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.InvalidOperationException: The cache refresher: b29286dd-2d40-4ddb -b325-681226589fec is not of type Umbraco.Core.Cache.IJsonCacheRefresher at umbraco.presentation.webservices.CacheRefresher.RefreshByJson(Guid uniqueIdentifier, String jsonPayload, String Login, String Password) --- End of inner exception stack trace --- at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.EndInvoke(IAsyncResult asyncResult) at Umbraco.Core.Sync.DefaultServerMessenger.PerformDistributedCall(IEnumerable`1 servers, ICacheRefresher refresher, MessageType dispatchType, IEnumerable`1 ids, Type idArrayType, String jsonPayload)

Instead inherited from MediaCacheRefresher and hooked on Refresh(string jsonPayload) i.e:

public class DistributedIndexUpdate : MediaCacheRefresher
{   public override void Refresh(string jsonPayload)
    {
        try
        {
            var medias = DeserializeFromJsonPayload(jsonPayload);
            if (medias.Any())
            {
                medias.ForEach(delegate(JsonPayload media)
                {
                    IndexMedia(ApplicationContext.Current.Services.MediaService.GetById(media.Id));
                });
            }
        }
        catch (Exception ex)
        {
            Log.InfoFormat("....");
        }
        base.Refresh(jsonPayload);
    }
    //the rest of the code...
}

would work on the same way ? Thanks, Elias

You'll be happy to know this should all be resolved with 7.1/6.2 see: http://issues.umbraco.org/issue/U4-3937

is working on a reply...
