The document outlines the importance of database performance monitoring for ensuring uninterrupted application service delivery, including key metrics for assessing database health and common issues faced by database administrators. It covers essential insights for tackling performance problems, disaster recovery strategies, and trends for database utilization to aid in future planning. Additionally, it highlights various database systems and their specific monitoring needs, emphasizing the role of resource utilization and capacity planning in optimizing performance in the big data era.
Database performance monitoring:Key to seamless application performance
- 1. Database performance monitoring: The key to seamless application performance
- 2. Agenda DB monitoring how to: Diving into the key metrics of database servers Essential insights for the database admin Optimizing database performance in the Big Data era Forecasting database utilization trends and planning capacity
- 3. Availability MemoryCPU Network Processes Hardware Disk 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
- 6. 1. DB monitoring how to: Diving into the key metrics of database servers
- 7. Availability Health Represents whether a particular database server is currently available to undertake requests. Represents the overall state of the Database server. Depends on the severity of all the other attributes. Up Dow n Clear Warning Critical
- 8. Buffer Manager stats • Buffer & Cache hit ratio • Page Life Expectancy • Cache used per minute
- 9. Connection stats • Connection time • Number of users connected to the system • Logins, Logouts per min • Number of SQL batch requests received by server
- 10. 2. Essential insights for the database admin A. Common database problems and how to tackle them • Database throws "cannot connect" error • Database response is slow towards requests • Not able to retrieve data when accessing a particular record in a web application B. Disaster Recovery • Backup monitoring • Replication monitoring
- 11. Discovery & mapping Database throws "cannot connect" error • Network issue • SQL Server configuration issue • Firewall issue • Client driver issue • Application configuration issue • Authentication and logon issue
- 12. Discovery & mapping Possible reasons: • Not enough resources • Queries taking more time to execute Database response is slow towards requests
- 13. MsSQL Log File & Data Files • See log file and data file details for individual SQL DBs • Generate reports for log and data files
- 14. Oracle Tablespace stats • Identify used & free bytes of individual table space. • Monitor Reads and Writes per min • Track data files & monitor datafile auto extend
- 15. MsSQL Top Queries by CPU
- 16. MsSQL Top Queries by CPU
- 17. MsSQL Slow running queries
- 18. Oracle Buffer Gets - Top 10 Queries • Buffer Gets • Execution • Buffer Gets per Execution
- 19. Oracle Disk Reads - Top 10 Queries
- 20. Discovery & mapping Not able to retrieve data when accessing a particular record in a web application
- 21. MsSQL -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.
- 22. Oracle- Session details • Identify ONLINE, OFFLINE, or INVALID sessions as well as sessions initiated by specific users. • Monitor number of memory sorts, table scans performed. • Track physical & logical reads of the session as well as buffer cache hit ratio
- 23. Oracle -Session summary • Know sessions wait time and its corresponding event. • Track account status and user account expiry date.
- 24. MsSQL Top waits by waiting tasks
- 25. MsSQL Most Blocked Queries
- 26. Oracle - Lock • Know which type of session lock type is being used. • Track blocked session time.
- 27. Discovery & mapping B. Disaster recovery Backup monitoring Replication monitoring (DR) is an area of security planning that aims to protect an organization from the effects of significant negative events. Let's break down the Disaster recovery plan into:
- 28. 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.
- 29. Replication stats • Log shipping status • Publications • Subscriptions • Replication agents • History of agents running in the SQL server.
- 30. Oracle Backup jobs • Know the number of running backup jobs count. • Get session key along with backup status.
- 31. Log apply gap • Get Log apply gap details for both Primary & Secondary DB. • Archive log Destination stats
- 32. Discovery & mapping 3. Optimizing database performance in the Big Data era
- 34. Cassandra Memory Utilization • Free Memory • Used Memory
- 35. MongoDB - Connection stats • Connections used • Connections available
- 36. Redis - DB stats • Number of keys • Number of expired keys
- 37. Slow transaction
- 38. Cassandra - Keyspace Latency • Read Latency (/min) • Write Latency (/min)
- 39. MongoDB-Lock & Asserted errors • Read Lock, Write Lock • Message, User asserts
- 40. Redis-Connected/Blocked clients • Connected clients • Blocked clients
- 42. Cassandra-Cluster • Node state • Unreachable nodes
- 45. Discovery & mapping 4. Forecasting database utilization trends and planning capacity
- 46. Trend analysis report Pull at a glance report of the DB server to have a quick glance at all monitored attributes
- 47. Trend analysis report Pull trend analysis report for a particular attribute the DB server to have a quick glance at all monitored attributes • History Report • Hour of Day Report • Day of Week Report • Statistical Report • Heat Chart
- 48. Compare performance attribute reports of different monitors. View & compare reports
- 49. • Balance hardware costs with computing needs. • Plan future utilization requirements. Forecast report
- 50. • Customize with widgets • Create and publish multiple dashboards • Unified business view of your entire IT infrastructure Dashboards
