Oracle ACFS Pre-defined Metric Types

Oracle ACFS provides the acfsmetric1 pre-defined metric type.

The acfsmetric1 metric set is defined for the storage virtualization model. The metrics are maintained as a summary record for either a selected set of tagged files or all files in the file system. Oracle ACFS file metrics include: number of reads, number of writes, average read size, average write size, minimum and maximum read size, minimum and maximum write size, and read cache (VM page cache) hits and misses.

Example:

typedef struct _ACFS_METRIC1 {
    ub2 acfs_version;
    ub2 acfs_type;
    ub4 acfs_seqno;
    ub8 acfs_nreads;
    ub8 acfs_nwrites;
    ub8 acfs_rcachehits;
    ub4 acfs_avgrsize;
    ub4 acfs_avgwsize;
    ub4 acfs_minrsize;
    ub4 acfs_maxrsize;
    ub4 acfs_minwsize;
    ub4 acfs_maxwsize;
    ub4 acfs_rbytes_per_sec;
    ub4 acfs_wbytes_per_sec;
    ub8 acfs_timestamp;
    ub8 acfs_elapsed_secs;
} ACFS_METRIC1;
