A pair of Fault tolerant EMS servers may be monitored independently as separate EMS Servers (E.g. by adding two ConnectionNodes in the servers.xml file, one for the primary server and and for the secondary). Alternatively, a single EMS server entry can be used to represent the fault tolerant pair, note the following:
Note: Monitoring Fault Tolerance on the EMS Appliance is slightly different than for EMS software, see next section.
The state of the EMS server is displayed in the State column on the main EMS server display, the following values can be displayed:
The fault tolerant state of the primary EMS server is displayed in the FaultTolerantState column on the main EMS server display, the following values can be displayed:
If no FaultTolerantState is shown then the EMS servers are not configured for FT or the EMS server is in the Standby state
The image below shows two EMS servers. EMS-SERVER1 is Active and in a FULLY_OPERATIONAL fault tolerant state, I.e. it is the primary server in a fault tolerant pair and the secondary is standing by in the case if failure. EMS-SERVER2 shows a different active EMS server from another fault tolerant pair however this server is in STANDALONE mode, I.e. there is no standby running, this would normally be considered an error state as one of the EMS servers may have failed leaving just a single server operational.
