Monitoring 
Proactive, automatic monitoring is the basis for reliable operation of your SAP system environment. SAP provides you with the infrastructure and recommendations needed to set up your alert monitoring to recognize critical situations for SAP NetWeaver including Embedded Search as quickly as possible.
You can use the following monitoring and administration tools to monitor Embedded Search:
CCMS
With CCMS, you can monitor your entire system landscape. If malfunctions or problems occur, alerts are generated. The appliance monitors and alerts can be connected to the customers's central monitoring system if available or be monitored in the appliance-internal CCMS.

TREX Admin Tool
Standalone administration and monitoring of TREX components and indexes.
