log in to Oracle Enterprise Manager using a client browser, the Cluster Database Home page appears where you can monitor the status of both Oracle Clusterware environments. Monitoring can include such things as: Notification if there are any VIP relocations Status of the Oracle Clusterware on each node of the cluster using information obtained through the Cluster Verification Utility (cluvfy) Notification if node applications (nodeapps) start or stop Notification of issues in the Oracle Clusterware alert log for the OCR, voting disk issues (if any), and node evictions The Cluster Database Home page is similar to a single-instance Database Home page. However, on the Cluster Database Home page, Oracle Enterprise Manager displays the system state and availability. This includes a summary about alert messages and job activity, as well as links to all the database and Automatic Storage Management (ASM) instances. For example, you can track problems

Crs Alert Log Location 11gr2
Multiple alert logs crs log file location 12c in RAC Oracle Database Tips by Burleson Consulting July 29, 2015 Question: Is it one alert log per instance or cssd log file location one per RAC database? I want to monitor by RAC alerts and I need to know if Oracle has multiple alerts logs in RAC databases. Are alert logs in the diagnostic_dest instance https://docs.oracle.com/cd/B28359_01/rac.111/b28255/troubleshoot.htm specific or database specific? If they are instance specific, how can you consolidate the alert log messages?Answer: Yes, each instance in a RAC cluster has it's own alert log. The 11g RAC Administrator's Guide under Appendix B Troubleshooting notes: Using Instance-Specific Alert Files in Oracle RAC Each instance in an Oracle RAC database has one alert file. The alert file for each instance, alert.SID.log, contains important http://www.dba-oracle.com/t_rac_alert_log_multiple_instance.htm information about error messages and exceptions that occur during database operations. Information is appended to the alert file each time you start the instance. All process threads can write to the alert file for the instance.The alert_SID.log file is in the directory specified by the DIAGNOSTIC_DEST parameter in the initdb_name.ora initialization parameter file. For monitoring you alert logs, I use scripts to scan each alert log in the RAC cluster for important messages and e-mail them to a separate location. If you don't want to write your own custom scripts, see my Oracle script download. In 11g and beyond, you can directly query the alert log with SQL, using x$dbgalertext. SQL against the alert log - You can define the alert log file as an external table and detect important messages with SQL and e-mail them to a central repository. Scripts - You can write Oracle shell scripts OS shell scripts to detect alert log messages. Ion - The Ion tool has complete mechanisms for setting custom alert log extracts. PL/SQL - You can write a SQL*Plus procedure using utl_file to read the alert log. Oracle Grid and Real Application Cluster

In the event of an error, it can contain path information to diagnostic logs that can provide specific information about the cause of errors. … The location of the Oracle Clusterware log file is CRS_home/log/hostname/alerthostname.log, where CRS_home is the directory in which Oracle Clusterware was installed and hostname is the host name of the local node.
