Citrix NetScaler HA Failover Monitoring
When your NetScaler appliances are running in a High Availability (HA) pair you should be aware when failovers occur, as this indicates an issue on one or both of the appliances, which you need to solve before both the appliances have the same issue. In the case the latter happens, or is already the case, the appliances will fail over continuously, which is known as HA failover ‘flip-flopping’.
