lpar_id The unique identifier for the logical partition (LPAR). /proc/ppc64/lparconfig perfstat_partition_total
purr The amount of CPU time that has been used by the partition. /proc/ppc64/lparconfig perfstat_partition_total
entitlement The CPU entitlement of the partition. /proc/ppc64/lparconfig perfstat_partition_total
cpus The number of CPUs on which the LPAR can run. /proc/ppc64/lparconfig perfstat_partition_total
capped Determines whether or not the entitlement of the LPAR is capped. If yes, then the LPAR cannot exceed its entitlement. If not, then the LPAR will be able to exceed its entitlement if there are spare CPU cycles available from another CPU on the system. /proc/ppc64/lparconfig perfstat_partition_total
smt Determines whether or not hyperthreading is available. /proc/ppc64/lparconfig perfstat_partition_total
memory_total The total amount of memory available to the LPAR, measured in bytes. /proc/meminfo perfstat_memory_total
memory_used The total amount of memory being used by the LPAR, measured in bytes. /proc/meminfo perfstat_memory_total
net_packets_tx The number of packets of data that have been sent over the network interface from the LPAR. /proc/net/dev perfstat_netinterface_total
net_packets_rx The number of packets of data that have been received over the network interface by the LPAR. /proc/net/dev perfstat_netinterface_total
net_bytes_tx The amount of data, measured in bytes, that has been sent over the network interface from the LPAR. /proc/net/dev perfstat_netinterface_total
net_bytes_rx The amount of data, measured in bytes, that has been received over the network interface by the LPAR. /proc/net/dev perfstat_netinterface_total
disk_kbytes_out The amount of data, in kilobytes, that has been written to the disk. /proc/diskstats perfstat_disk_total
