Fixed In:

Opened: Aug 05, 2020
Severity: 3-Major

Symptoms

There are two context and syntax-related issues: -- In v14.x, the context for tmsh analytics commands related to server side connections changed. For example, 'total-server-side-conns' became a simple 'server-side-conns'. -- In v13.x and 14.x, the calculation method for 'max-tps' changed from cumulative to commutative.

Impact

Stats names do not reflect their actual values. The 'max-tps' value is no longer valid for client IP context. These changes might have varied impacts, depending on your configuration.

Conditions

This occurs in either of the following scenarios: -- Using tmsh analytics commands related to max-tps in v13.x or later. -- Using tmsh analytics commands related to server side connections in BIG-IP v14.x and later.

Workaround

None

Fix Information

-- Label names for tmsh analytics commands related to server side connections changed (for example: the tmsh display name changed from 'total-server-side-conns' to 'server-side-conns', with similar changes for the other server side connection stats). -- The 'max-tps' formula changed to be commutative instead of cumulative, so it is no longer relevant in the 'client-ip' context.

Behavior Change

-- Label names for tmsh analytics commands related to server side connections changed (for example: the tmsh display name changed from 'total-server-side-conns' to 'server-side-conns', with similar changes for the other server side connection stats). -- The 'max-tps' formula changed to be commutative instead of cumulative, so it is no longer relevant in the 'client-ip' context.
