NAME

6       ipmctl-show-performance - Shows performance metrics for one or more
7       DCPMMs
8

SYNOPSIS

10       ipmctl show [OPTIONS] -performance [METRICS] [TARGETS]
11

DESCRIPTION

13       Shows performance metrics for one or more DCPMMs.
14

OPTIONS

16       -h, -help
17           Displays help for the command.
18
19       -o (text|nvmxml), -output (text|nvmxml)
20           Changes the output format. One of: "text" (default) or "nvmxml".
21

METRICS

23       Restricts output to a specific performance metric by supplying the
24       metric name. See RETURN DATA for more information. One of:
25
26       ·   MediaReads
27
28       ·   MediaWrites
29
30       ·   ReadRequests
31
32       ·   WriteRequests
33
34       ·   TotalMediaReads
35
36       ·   TotalMediaWrites
37
38       ·   TotalReadRequests
39
40       ·   TotalWriteRequests
41
42       The default is to display all performance metrics.
43

TARGETS

45       -dimm (DimmIDs)
46           Restricts output to the performance metrics for specific DCPMM by
47           supplying one or more comma separated DCPMM identifiers. The
48           default is to display performance metrics for all manageable DCPMM.
49

EXAMPLES

51       Shows all performance metrics for all DCPMMs in the server.
52
53       ipmctl show -dimm -performance
54
55       Shows the number of 64 byte reads since last AC cycle for all DCPMMs in
56       the server.
57
58       ipmctl show -dimm -performance MediaReads
59

RETURN DATA

61       This command displays a table of the specified metrics for each
62       specified DCPMM. Applying a specific DCPMM target limits the rows in
63       the table. Applying a specific metric name target limits the columns in
64       the table.
65
66       DimmID
67           The DCPMM identifier
68
69       MediaReads
70           Number of 64 byte reads from media on the DCPMM since last AC
71           cycle.
72
73       MediaWrites
74           Number of 64 byte writes to media on the DCPMM since last AC cycle.
75
76       ReadRequests
77           Number of DDRT read transactions the DCPMM has serviced since last
78           AC cycle.
79
80       WriteRequests
81           Number of DDRT write transactions the DCPMM has serviced since last
82           AC cycle.
83
84       TotalMediaReads
85           Number of 64 byte reads from media on the DCPMM over its lifetime.
86
87       TotalMediaWrites
88           Number of 64 byte writes to media on the DCPMM over its lifetime.
89
90       TotalReadRequest
91           Number of DDRT read transactions the DCPMM has serviced over its
92           lifetime.
93
94       TotalWriteRequest
95           Number of DDRT write transactions the DCPMM has serviced over its
96           lifetime.
