How to verify if Peer cache is working

Question

Hi All

We have recently implemented Peer Cache in our environment. 5 machines have been selected as peer cache source and deployed with client setting for Peer Cache.
We have verified that client setting have been applied to these designated machines , but i want to confirm if the peer cache is actually working. If the peers in the same boundary segment are able to get content from the peer source.

Please advice if any query/report can be used identify if the peers for the peer cache source.

Hi @Ramesh RK ,

We could check CAS.log to check it is working.

For example, if the content is from DP not peer cache, it is recorded as the following screenshot:

The clients are getting content from their peer caching friends. This is the interesting line in the log.

Besides, please go to the Monitoring workspace and select the Distribution Status / Client Data Sources node.

Hi All

After a long struggle happened to create a SSRS report using the below SQL query that suffice my requirement.
This helps to get the information on PeerSource, Peers connected to it, ContentID downloaded along with the boundary information.

	SELECT distinct sd.name0 [PeerClient_Name], cdhSources.HostName [PeerSource_Name], vbo.Value [Boundary_Name], vbg.Name [BG_Name],   
		cdhSources.DistributionPointType, cdhSources.ContentID, his.StartTime  
		from SYSTEM_DISC sd    
		JOIN ClientDownloadHistory his on his.ClientId=sd.ItemKey   
		JOIN ClientDownloadHistoryBoundaryGroups bg on bg.DownloadHistoryID=his.ID   
		JOIN ClientDownloadHistorySources cdhSources on cdhSources.DownloadHistoryID = his.ID  
		JOIN vSMS_BoundaryGroupMembers Bgm on bgm.GroupID = bg.BoundaryGroup  
		JOIN vSMS_Boundary vbo on vbo.BoundaryID = bgm.BoundaryID  
		join v_BoundaryGroup vbg on vbg.GroupID = bgm.GroupID  
		Where DistributionPointType in ('3')   
		and vbg.Name in ('UK-RDG01') -- BOundary Group  
		and DATEDIFF(dd,his.StartTime,GETDATE()) < 8  
		ORDER BY his.StartTime DESC
