Visualizzare le statistiche di BranchCache

Collaboratori

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.

A proposito di questa attività

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.

Fasi
  1. 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
  2. Visualizzare i contatori relativi a BranchCache utilizzando statistics catalog counter show 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

                                    requests were made in rapid succession
        avg_directory_depth         Average number of directories 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

                                    content was not available on the server.
