Examining MVFS cache statistics

Use the cleartool getcache command to display information about MVFS cache statistics on a host. getcache -mvfs presents information about file and directory handle caches and also about attribute caches. File and directory handle cache statistics are presented in the form current-number-on-list/list-capacity and (percentage-of-list-capacity). Attribute cache statistics show each caches's size and total cache misses since the last MVFS restart. For example:

cleartool getcache -mvfs
Mnodes: (active/max)    1791/8192 (21.863%)
Mnode freelist:         1701/1800 (94.500%)
Cltxt freelist:         737/1800 (40.944%)

DNC:    Files:          848/1600 (53.000%)
        Directories:    185/400 (46.250%)
        ENOENT:         827/1600 (51.688%)

RPC handles:            4/10 (40.000%)
