Definition
Number of control intervals written for active log per second
The total number of log CI's written. This value includes CI rewrites and COPY1 and COPY2 active log data set writes. If a given CI is rewritten five times, this counter is incremented by five. This counter, multiplied by 4KB and divided by the statistics interval in seconds, represents the number of bytes per second of log data written to the active log data sets. When this value exceeds 1MB/SEC per log copy, attnetion should be paid to log data set I/O tuning.
