Exibir estatísticas do BranchCache
Você pode exibir estatísticas do BranchCache para, entre outras coisas, identificar o desempenho do cache, determinar se sua configuração está fornecendo conteúdo em cache para clientes e determinar se os arquivos hash foram excluídos para dar espaço aos dados de hash mais recentes.
O hashd
objeto estatístico contém contadores que fornecem informações estatísticas sobre hashes BranchCache. O cifs
objeto estatístico contém contadores que fornecem informações estatísticas sobre a atividade relacionada ao BranchCache. Você pode coletar e exibir informações sobre esses objetos no nível avançado de privilégios.

Defina o nível de privilégio como avançado:
set -privilege advanced
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

Exiba os contadores relacionados ao BranchCache usando o
statistics catalog counter show
comando.Para obter mais informações sobre contadores de estatísticas, consulte a página de manual deste comando.
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....
