Measures reported by LtmVServerTest

A virtual server is a traffic-management object on the BIG-IP system that is represented by an IP address and a service. Clients on an external network can send application traffic to a virtual server, which then directs the traffic according to your configuration instructions. The main purpose of a virtual server is often to balance traffic load across a pool of servers on an internal network. Virtual servers increase the availability of resources for processing client requests.

Not only do virtual servers distribute traffic across multiple servers, they also treat varying types of traffic differently, depending on your traffic-management needs. Therefore, the avalibility of the virtual servers in the system is imperative for balancing the load. The LtmVServerTest test exactly helps administrators in identifying the availiabity status of the virtual servers.

This test reports the current availability status of each virtual server in a pool and if the virtual server is available, this tests reports the current activity status of each virtual server.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Avail_status Indicates the current status of this virtual server.   The values that this measure can report and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
Unknown 0
None 1
Available 2
Currently not available 3
Offline 4
Unlicensed 5

Note:

By default, this measure can report the Measure Values mentioned above while indicating the current status of the virtual server. However, the graph of this measure is indicated using the numeric equivalents 0 - 5 only.
Vs_status Indicates the current activity status of this virtual server as specified by the user.   This measure appears only if the Avail_status measure reports the Measure Value Available.

The values that this measure can report and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
None 0
Enabled 1
Disabled 2
Disabled by parent 3

Note:

By default, this measure can report the Measure Values mentioned above while indicating the current activity status of the virtual server. However, the graph of this measure is indicated using the numeric equivalents 0 - 3 only.
