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.
