 Badge
Status displays the state of the LTMs. The state of a LTM is derived from the status of Virtual Servers.
  • If all Virtual Servers are available, status is 1, then the color is Green. LTM is available.
  • If Virtual Servers are partially available with a mixed status of 1,2, 3, 4, then the color is Orange. LTM is partially available.
  • If all Virtual Servers are not available with a status of 4, then the color is Red. LTM is unavailable.

Displays the total number of Virtual Servers, Pools, and Pool Members that are associated with a selected LTM.

It also displays the state of the Virtual Servers, Pools, and Pool Members for the LTM. The value and color code indicate the number of devices that are unavailable, partially available, and available. These badge widget allows drill down to their respective drill-down pages.

Explanation for the color codes is as follows:
  • Green: Available
  • Orange: Partially Available
  • Red: Unavailable
CPU Utilization (%) Gauge CPU availability that is used across all available cores in the selected LTM.
Memory Utilization (%) Gauge Memory availability that is used across all available cores in the selected LTM.
Top 5 Virtual Servers by Current Connections Line Top five Virtual Servers that are available by the current connections in the selected LTM. It drills down to the specific Virtual Servers Details dashboard.
Note: The Time Zoom feature is available for all the Line charts in this dashboard.

It's a dynamic chart that allows drill down to the Virtual server details dashboard.
Current Connections Trend Line Current or active connections that are available to that LTM at a particular time that is based on the selected time period. It is a measure of the number of client/server requests that can be handled.
Connections per Second Trend Line Active LTM connections that are available per second.
Inbound Throughput (bps) Trend Line Measured in bits per second. Typically, it is the amount of data that is sent to and from the LTM to the client.
Outbound Throughput (bps) Trend Line Measured in bits per second. Typically, it is the amount of data that is sent to and from the client to the LTM.
