CgroupDelta
data class CgroupDelta(val throttled: Long? = null, val memoryMax: Long? = null, val oom: Long? = null, val oomKill: Long? = null)(source)
How much the counters of the cgroup that held the run grew while it ran: nr_throttled of cpu.stat, and max, oom and oom_kill of memory.events. A field is null when the file or the counter was not readable, so absent never reads as zero.
