Monitoring | Farms Stats

POSTED ON 15 January, 2019

This section details all farms and load balancing services statistics configured. It shows a table with the number of current Established and Pending connections for every LSLB farm.

The table includes the following columns:

FARM NAME. Farm identification name.
PROFILE. Farm profile of a given farm.
VIRTUAL IP. IP address used by the farm to manage, distribute and create a high available service.
VIRTUAL PORT. Port used by the load balancing service to manage and distribute farm.
ESTABLISHED CONNS. Current established and already assured connections of a given farm. It doesn’t need to mean 1 connection per connected client.
PENDING CONNS. Current pending connections or not already assured connections of a given farm.
STATUS. The STATUS is shown by mean the colour bullets as follow:

  • Green. Means UP. Farm is running and all backends are UP.
  • Red. Means DOWN. Farm is stoped.
  • Orange. Means RESTART NEEDED. There are recent changes that need a farm restart to be applied.
  • Black. Means CRITICAL. The farm is UP but there is not backend available or they are in maintenance mode
  • Blue. Means PROBLEM. Farm is running but at least one backend is down.
  • Yellow. Means MAINTENANCE. Farm is running but at least one backend is in maintenance mode.

The first column with icon Icon expand tableexpands the row with new tables of Backends stats and Sessions stats.
