Visualizzare le statistiche di BranchCache
È possibile visualizzare le statistiche di BranchCache, tra l'altro, per identificare le prestazioni del caching, determinare se la configurazione fornisce contenuti memorizzati nella cache ai client e determinare se i file hash sono stati eliminati per fare spazio a dati hash più recenti.
Il hashd
Oggetto Statistic contiene contatori che forniscono informazioni statistiche sugli hash BranchCache. Il cifs
Oggetto Statistic contiene contatori che forniscono informazioni statistiche sull'attività correlata a BranchCache. È possibile raccogliere e visualizzare informazioni su questi oggetti a livello di privilegi avanzati.

Impostare il livello di privilegio su Advanced (avanzato):
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

comando.Per ulteriori informazioni sui contatori delle statistiche, vedere la pagina man di questo 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....
