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. |
