Example 1 with StatsRestRep

use of com.emc.vipr.model.sys.healthmonitor.StatsRestRep in project coprhd-controller by CoprHD.

the class HealthMonitorService method getStats.

/**
 * Get statistics of virtual machine and its active services
 * Virtual machine stats include memory usage, I/O for each device,
 * load average numbers
 * Service stats include service memory usage, command that invoked it,
 * file descriptors count and other stats (uptime, start time, thread count).
 * <p/>
 * If interval value is passed it will return differential disk stats: difference between first report (contains stats for the time
 * since system startup) and second report (stats collected during the interval since the first report).
 *
 * @brief Show disk, memory, service statistics of all virtual machines
 * @param nodeIds  node ids for which stats are collected.
 * @param nodeNames node names for which stats are collected.
 * @param interval Specifies amount of time in seconds for differential stats.
 * @prereq none
 * @return Stats response
