Device health
metrics
The following list defines metrics sets and their corresponding metrics for the
application statistics displayed in the dimensions pane table in the
Device
Health
screen of the GUI. Each table row is read from left to right, where each
metric set is defined as it would relate to each listed dimension, and each metric corresponds
to its metric set.Dimension | Metric Set | Metric Set Definition | Metric | Metric Definition |
|---|---|---|---|---|
BIG-IP Host Names BIG-IP Blades Process Name Process ID BIG-IP Modules | CPU | The percent CPU usage based on overall and specific activities of
the BIG-IP system devices. | System | The average (percent) CPU usage for all the running BIG-IP systems over a given
time period. |
User | ||||
I/O Wait | The percentage of time (during the selected time period) that a given CPU is idle
for an I/O wait operation. This occurs when at least one outstanding I/O disk
operation is requested by a task scheduled on system CPU. | |||
Stolen | The percentage of time a virtual CPU waits for real CPU when the hypervisor is
servicing another virtual machine. | |||
Usage | The percent CPU usage for the various processes used bu the BIG-IP
system. | |||
BIG-IP Host Names BIG-IP Blades | Memory Usage | The percent RAM used by system processes of the BIG-IP system
devices. | Other | The average percentage of used RAM from other device processes. |
TMM | The average percentage RAM used by device TMM processes. | |||
Total | The average percentage of RAM used by the system's devices. | |||
BIG-IP Host Names BIG-IP Blades BIG-IP CPU Cores | Disk Merges | The average rate of merges per second (merge/s) at which an
application completes a read or write to a hard disk. This indicated the speed of
successful disk merges. | Avg/s Read | The average rate per second that an application completes a read merge from the
hard disk. |
Avg/s Write | The average rate per second that an application completes a read merge from the
hard disk. | |||
BIG-IP Host Names BIG-IP Blades | Disk Operations | The average rate of operations per second (Ops) at which an
application completes a read or write to a hard disk. This operation indicates the
speed at which an application saves or extracts data from a hard disk. | Avg/s Read | The average rate per second that an application completes a write merge from the
hard disk. |
Avg/s Write | The average rate per second that an application completes a write operation to
the hard disk. | |||
BIG-IP Host Names BIG-IP Blades | Disk Throughput | The average rate of bytes per second (Bps) that the application
reads or writes from hard disk data. This indicates the speed of the application for
the client. | Avg/s Read | The average rate per second of bytes that application reads from the hard
disk. |
Avg/s Write | The average rate per second of bytes that application writes to the hard
disk. | |||
BIG-IP Host Names Interface Names | Throughput Drops | The average rate of packets per second (pps) that were dropped by
the BIG-IP interface or discarded by the TMM over the course of the
transaction. | Avg/s Out | The average rate of packets per second that were accepted by the BIG-IP
interface, but discarded by the TMM. |
Avg/s In | The average rate of packets per second that were dropped by the BIG-IP interface.
| |||
Total Out | The total number of packets that were accepted by the BIG-IP interface, but
discarded by the TMM. | |||
Total In | The total number of packets that were dropped by the BIG-IP interface. | |||
BIG-IP Host Names Interface Names | Throughput Error | The average rate packets per second (pps) that were corrupted or
arrived incomplete over the course of the transaction across the network. | Total In | The total number of packets received as throughput error. |
Total Out | The total number of packets transmitted out as throughput error. | |||
Avg/s In | The average packets per second received as throughput error. | |||
Avg/s Out | The average packets per second transmitted out at through |
