您可以显示 BranchCache 统计信息，以便确定缓存的执行情况，确定您的配置是否正在向客户端提供缓存内容，以及确定是否删除了哈希文件，以便为最新的哈希数据腾出空间。
关于此任务
。 hashd 统计信息对象包含计数器、这些计数器可提供有关anchCache哈希的统计信息。。 cifs 统计信息对象包含计数器、这些计数器提供有关与anchCache相关的活动的统计信息。您可以在高级权限级别收集和显示有关这些对象的信息。
步骤

将权限级别设置为高级：
set -privilege advancedcluster1::> set -privilege advanced Warning: These advanced commands are potentially dangerous; use them only when directed to do so by support personnel. Do you want to continue? {y|n}: y -
使用显示与anchCache相关的计数器
statistics catalog counter show命令：有关统计信息计数器的详细信息，请参见此命令的手册页。
cluster1::*> statistics catalog counter show -object hashd Object: hashd Counter Description --------------------------- ---------------------------------------------- branchcache_hash_created Number of times a request to generate BranchCache hash for a file succeeded. branchcache_hash_files_replaced Number of times a BranchCache hash file was deleted to make room for more recent hash data. This happens if the hash store size is exceeded. branchcache_hash_rejected Number of times a request to generate BranchCache hash data failed. branchcache_hash_store_bytes Total number of bytes used to store hash data. branchcache_hash_store_size Total space used to store BranchCache hash data for the Vserver. instance_name Instance Name instance_uuid Instance UUID node_name System node name node_uuid System node id 9 entries were displayed. cluster1::*> statistics catalog counter show -object cifs Object: cifs Counter Description --------------------------- ---------------------------------------------- active_searches Number of active searches over SMB and SMB2 auth_reject_too_many Authentication refused after too many requests were made in rapid succession avg_directory_depth Average number of directories crossed by SMB and SMB2 path-based commands avg_junction_depth Average number of junctions crossed by SMB and SMB2 path-based commands branchcache_hash_fetch_fail Total number of times a request to fetch hash data failed. These are failures when attempting to read existing hash data. It does not include attempts to fetch hash data that has not yet been generated. branchcache_hash_fetch_ok Total number of times a request to fetch hash data succeeded. branchcache_hash_sent_bytes Total number of bytes sent to clients requesting hashes. branchcache_missing_hash_bytes Total number of bytes of data that had to be read by the client because the hash for that content was not available on the server. ....Output truncated.... -
