Enum StatsRequest

pub enum StatsRequest {
    GetMemoryStats {
        responder: StatsGetMemoryStatsResponder,
    },
    GetMemoryStatsExtended {
        responder: StatsGetMemoryStatsExtendedResponder,
    },
    GetMemoryStatsCompression {
        responder: StatsGetMemoryStatsCompressionResponder,
    },
    GetCpuStats {
        responder: StatsGetCpuStatsResponder,
    },
    GetCpuLoad {
        duration: i64,
        responder: StatsGetCpuLoadResponder,
    },
}

Protocol for providing kernel stats. This is roughly a wrapper around zx_object_get_info for the ZX_INFO_KMEM_STATS and ZX_INFO_CPU_STATS topics, which today require the very powerful ‘Root Resource’ capability to obtain. Instead of vending out that capability, programs that just want stats should use this service instead. If for some reason the protocol fails to retrieve stats, which will be an un-recoverable error, it will close the channel.

GetMemoryStats

Fields

responder: StatsGetMemoryStatsResponder

GetMemoryStatsExtended

Fields

responder: StatsGetMemoryStatsExtendedResponder

GetMemoryStatsCompression

Fields

responder: StatsGetMemoryStatsCompressionResponder

GetCpuStats

Fields

responder: StatsGetCpuStatsResponder

GetCpuLoad

Gets the average load as a percentage (0.0 - 100.0) from each CPU over the specified duration.

Load is calculated as (100 - %idle), where %idle is the percentage value of idle_time (from PerCpuStats) over a time duration.

Fields

duration: i64

responder: StatsGetCpuLoadResponder
