Application service device charts

This table describes the menu options and charts found in the application service dashboard (Applications > APPLICATIONS > <Application Name> > <Application Service>). 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.

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.
