The Uptime Infrastructure Monitor agent that is installed on a logical partition of an AIX LPAR system collects the following performance metrics:

MetricExplanationFile on LinuxAIX System Calls in libperfstat
lpar_idThe unique identifier for the logical partition (LPAR)./proc/ppc64/lparconfigperfstat_partition_total
purrThe amount of CPU time that has been used by the partition./proc/ppc64/lparconfigperfstat_partition_total
entitlementThe CPU entitlement of the partition./proc/ppc64/lparconfigperfstat_partition_total
cpusThe number of CPUs on which the LPAR can run./proc/ppc64/lparconfigperfstat_partition_total
cappedDetermines 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/lparconfigperfstat_partition_total
smtDetermines whether or not hyperthreading is available./proc/ppc64/lparconfigperfstat_partition_total
memory_totalThe total amount of memory available to the LPAR, measured in bytes./proc/meminfoperfstat_memory_total
memory_usedThe total amount of memory being used by the LPAR, measured in bytes./proc/meminfoperfstat_memory_total
net_packets_txThe number of packets of data that have been sent over the network interface from the LPAR./proc/net/devperfstat_netinterface_total
net_packets_rxThe number of packets of data that have been received over the network interface by the LPAR./proc/net/devperfstat_netinterface_total
net_bytes_txThe amount of data, measured in bytes, that has been sent over the network interface from the LPAR./proc/net/devperfstat_netinterface_total
net_bytes_rxThe amount of data, measured in bytes, that has been received over the network interface by the LPAR./proc/net/devperfstat_netinterface_total
disk_kbytes_outThe amount of data, in kilobytes, that has been written to the disk./proc/diskstatsperfstat_disk_total
disk_kbytes_inThe amount of data, in kilobytes, that has been read from the disk./proc/diskstatsperfstat_disk_total
