显示 BranchCache 统计信息
可在众多内容中，显示 BranchCache 统计信息，以识别缓存执行状况，确定您的配置是否正在为客户端提供已缓存内容，并确定哈希文件是否已删除，以便为更多最近哈希数据留出空间。
关于本任务
hashd 统计信息对象包含可提供 BranchCache 哈希相关统计信息的计数器。 cifs 统计信息对象包含可提供 BranchCache 相关活动统计信息的计数器。可以高级权限级别收集并显示关于这些对象的信息。- 将权限级别设置为高级：set -privilege advanced
示例
cluster1::> 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 statistics catalog counter show 命令显示 BranchCache 相关计数器。有关统计信息计数器的更多信息，请参阅此命令的手册页。
示例
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.... - 使用 statistics start 和 statistics stop 命令收集 BranchCache 相关统计信息。有关收集统计信息的更多信息，请参阅《性能监控功能指南》。
示例
cluster1::*> statistics start -object cifs -vserver vs1 -sample-id 11
Statistics collection is being started for Sample-id: 11
cluster1::*> statistics stop -sample-id 11
Statistics collection is being stopped for Sample-id: 11 - 使用 statistics show 命令显示收集的 BranchCache 统计信息。有关显示统计信息的更多信息，请参阅《性能监控功能指南》。
