The nodeStatistics data type retrieves information about the statistics of nodes in your HCP system.

nodeStatistics data type properties

The next table describes the properties included in the nodeStatistics data type.

Property name Data type Description
backEndBytesRead Float Average number of bytes read from the node per second over the back-end network.
backEndBytesWritten Float Average number of bytes written to the node per second over the back-end network.
backendIpAddress String Backend IP address.
blocksRead Float Average number of blocks read from the logical volume per second.
blocksWritten Float Average number of blocks written to the logical volume per second.
collectionTimestamp Integer Exact time that the statistics were collected in milliseconds.
cpuMax Float Maximum amount of CPU capacity allotted for HCP processes.
cpuSystem Float Percentage of CPU capacity used by the operating system kernel.
cpuUser Float Percentage of CPU capacity used by HCP processes.
diskUtilization Float Use of the communication channel between the operating system and the logical volume as a percent of the channel bandwidth.
freeBytes Long Available free space on a HCP volume.
freeInodes Long Available free inodes on a HCP volume.
frontEndBytesRead Float Average number of bytes read from the node per second over the front-end network.
frontEndBytesWritten Float Average number of bytes written to the node per second over the front-end network.
frontendIpAddresses List List of front-end IP addresses. This property lists one or two IP addresses (IPv4 and/or IPv6).
id Float Name of the logical volume.
ioWait Float Percentage of CPU capacity spent waiting to access logical volumes that are in use by other processes.
managementBytesRead Float Average number of bytes read from the node per second over the management port network. This is returned only if you have configured the management port network on the node.
managementBytesWritten Float Average number of bytes written to the node per second over the management port network. This is returned only if you have configured the management port network on the node.
managementIpAddresses List List of management network IP addresses. This is returned only if you have configured the management port network on the node.
maxBackEndBandwidth Integer Maximum amount of CPU capacity allotted for HCP processes.
maxFrontEndBandwidth Integer The maximum amount of CPU capacity allotted for HCP processes.
maxHttpConnections Integer Maximum number of HTTP connections.
maxHttpsConnections Integer Maximum number of HTTPS connections.
maxManagementPortBandwidth Integer Maximum amount of CPU capacity allotted for HCP processes. This is returned only if you have configured the management port network on the node.
nodeNumber Integer Number of the node.
openHttpConnections Integer Number of open HTTP connections.
openHttpsConnections Integer Number of open HTTPS connections.
requestTime Integer Exact time that the request was issued in milliseconds.
swapOut Float Average number of pages swapped out of memory per second.
totalBytes Long Total size of an HCP volume.
totalInodes Long Maximum inodes limit of a HCP volume.
transferSpeed Float Transfer speed for the logical volumes specified as the number of input/output requests per second.
