Monitor database essentials with Applications Manager

  1. 1. Essential Database management with ManageEngine Applications Manager
  2. 2. Agenda MS SQL Database MonitoringWhy Database Monitoring? Oracle Database Monitoring Database reports & custom dashboards
  3. 3. Why Monitoring? • Monitor business critical metrics to ensure uninterrupted service delivery • Analyzing Database performance and resolve performance issues before service disruption • Analyzing root cause of common performance issues and eliminating recurring issues • Trend analysis to know how resources are being used and plan future upgrades
  4. 4. What to Monitor? • Database server: Availability, response time, free space, user sessions • Instance: Memory, scheduled jobs, blocking, waits, workload • Database: Status, backups, datafile/logfile growth • Top Queries by: I/O, CPU, waits, frequently executed queries
  5. 5. Tools Used • Perfmon • Extended Events • DMVs and System views • Query Store • Custom Scripts Note: Some tools do not work with all versions of servers. Please check version compatibility if they don't.
  6. 6. Supported databases
  7. 7. Prerequisites to add DB servers • Protocol used: JDBC connection • Ports required: Port used by the DB server (SQL:1433,Oracle:1521) • User Permissions: MS SQL:$mssql Oracle DB:$OracleDatabaseServers
  8. 8. Discovery & mapping MsSQL Database Server Monitoring
  9. 9. Represents whether a particular monitor is currently available to undertake requests. Represents the overall state of the monitor. Depends on the severity of all the other attributes. Up Down Availabilit y Clear Warning Critical Health
  10. 10. Log details & DB overview Monitor each DB & its underlying metrics
  11. 11. Buffer Manager stats Monitor metrics like: • Buffer & Cache hit ratio • Page lookups, reads, writes per minute • Cache used per minute
  12. 12. Connection stats Monitor metrics like: • Connection time • Number of users connected to the system. • Logins, Logouts per min • Number of SQL batch requests received by server.
  13. 13. Performance graphs Applications Manager presents a host of performance metrics for the SQL Servers.
  14. 14. Top CPU queries Visualize queries consuming more CPU usage during execution
  15. 15. Backup/ Restore stats Displays the performance metric about various SQL backup set present in the SQL Server. Select Action to enable/disable monitoring, and reset status.
  16. 16. Replication stats Display information of log shipping status, publications, subscriptions, information about each replication agents, agents history running in the corresponding SQL server.
  17. 17. Session details Displays the SQL server session ID running in SQL Server along with its status. Shows information on blocked request and allows user to kill user session.
