Application service device charts
This table describes the menu options and charts found in the
application service dashboard (). Select the option marked in the image to view charts at the bottom of the
screen. These charts display the trends of the host BIG-IP device, or service scaling group.
Each chart displays an aspect of the devices as a function of the selected time
period.
ANALYTICS Menu Option | Description |
|---|---|
CPU Usage
| The percentage of CPU usage based on overall
and specific activities of the BIG-IP system devices. Metric Unit: Percent Legend: User: The average percentage of
CPU usage for the all the BIG-IP user space programs over a given
time period. System: The average percentage
of CPU usage for all the running BIG-IP systems over a given time
period 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. |
Top Cores
| The six, most active CPU cores for all
monitored BIG-IP devices. Metric Unit:
Percent Legend: CPU core |
Memory
| The percentage of RAM used by system processes
of the monitored BIG-IP devices. Metric Unit:
Percent Legend: TMM: The average percentage of RAM used by device TMM
processes. Total: The average percentage of
RAM used by all devices Other: The average
percentage of used RAM from non-TMM processes. |
Throughput
| The average rate of traffic (in bytes)
processed by the BIG-IP device interfaces. Metric
Unit: Average/s Legend: In: The average rate of incoming traffic to the
BIG-IP devices. Out: The average rate of
outgoing traffic from the BIG-IP devices. |
Connections
| The average number of connections that are
open at the same time, on either the client-side or the server-side. Metric Unit: Count
Legend: Client Side: The average number of
concurrent connections at the client side. Server Side: The average number of concurrent connections at the
server side. |
HTTP
| The transaction includes all HTTP request and
response messages passed between the client, BIG-IP system, and
server. Metric Unit: Average/s Legend: Transactions:
Average number of HTTP transactions per second that were processed
by the BIG-IP devices. |
Dropped
| The average rate of packets per second (pps)
that were dropped by the BIG-IP device interfaces or discarded by the
TMM over the course of the transaction. Metric
Unit: Average/s Legend: In: The average rate of packets per second that
were dropped by the BIG-IP interface. Out:
The average rate of packets per second that were accepted by the
BIG-IP interface, but discarded by the TMM. |
Errors
| The average rate packets per second (pps) that
were corrupted or arrived incomplete over the course of the transaction
across the network, Metric Unit: Average/s Legend: In: The average
packets per second received as throughput error. Out: The average packets per second transmitted
out at throughput error. |
