Logstream statistics section

Offsets		Name	Length	Format	Description
0	0	SMF23LSL	2	binary	Length of the logstream name in SMF23LSN.
2	2	SMF23LSN	26	character	Logstream name.
28	1C	SMF23LFA	4	binary	Amount of each buffer allocation.
32	20	SMF23LFT	4	binary	Total amount of buffer storage currently used (in bytes).
36	24	SMF23LFH	4	binary	Binary high water mark of the buffer allocation (in bytes).
40	28	SMF23LFM	4	binary	Buffer storage maximum in effect (DSPSIZMAX value in bytes).
44	2C	SMF23LFL	4	binary	Binary buffer warning level in effect (BUFUSEWARN binary value).
48	30	SMF23LFG	4	binary	Various flags: Bit Meaning when set 0 When on, the buffer warning level in effect was from the global option. 1 When on, the buffer size (DSPSIZMAX) in effect was from the global option. 2 When on, compression is requested for records written to this log stream by SMF configuration. When off, compression is not requested. 3 When on, compression is prepared. This log stream is ready to compress records, or in other words, hardware is capable of using zEDC, and all setup for compression succeeded. When off, hardware is not capable of using zEDC or compression setup failed. See message IFA730I. 4 When on, compression is available. The last use of zEDC was successful, and it indicated zEDC Express® features were available to satisfy compression requests. When off, at the last request, zEDC Express features were not available to satisfy compression requests. 5 The current PERMFIX value for this log stream is the global PERMFIX value. In the SMF configuration, a log stream PERMFIX value was not specified.

SMF configuration parameter PERMFIX defines the maximum storage SMF can keep registered to zEDC. The following fields represent amounts of storage registered to zEDC for this log stream.

Offsets		Name	Length	Format	Description
52	34	SMF23PFT	4	binary	Total storage SMF is currently using for zEDC for this log stream. Value does not account for 1MB needed by each log stream using zEDC. Value may be up to 2MB greater than the defined PERMFIX value depending on usage.
56	38	SMF23PFM	4	binary	Max storage SMF can use for zEDC for this log stream. Configuration-defined PERMFIX value.
60	3C	SMF23PFH	4	binary	High water mark of storage SMF has used for zEDC for this log stream connection.
64	40	SMF23CWN	4	binary	Number of log blocks written containing compressed records during this interval.
68	44	SMF23NCN	4	binary	Number of log blocks written containing non-compressed records during this interval.
72	48	SMF23BBC	8	binary	zEDC uncompressed bytes total. For logstreams with compressed data, this field contains the total number of uncompressed bytes that zEDC successfully compressed during the interval. For logstreams with no compressed data, this field will contain zeroes.
80	50	SMF23BAC	8	binary	zEDC compressed bytes total. For logstreams with compressed data, this field contains the total number of compressed bytes that were written to the logstream during the interval. For logstreams with no compressed data, this field will contain zeroes.
