DB2 UDB Monitoring

Features for DB2

Germain can be configured to monitor availability and performance of DB2 database servers.

Database availability

Monitor the availability of the DB2 database to ensure it is up and running. Track uptime and receive alerts if the database goes down or experiences any connectivity issues.

Performance metrics

Monitor key performance metrics of the DB2 database, including CPU usage, memory utilization, disk I/O, and network traffic. These metrics help identify any bottlenecks or resource constraints that could impact the performance of the database.

Query performance

Monitor the performance of SQL queries executed against the DB2 database. Track metrics such as query response time, execution plans, and index usage. Identify slow-running queries and optimize their performance to improve overall database efficiency.

Database connections

Monitor the number of active database connections and track connection usage. Identify any connection leaks or excessive connections that could impact the performance and scalability of the database.

Disk space and tablespace utilization

Monitor the disk space usage of the DB2 database and its tablespaces. Ensure that there is sufficient disk space available for data storage and log files. Identify any tablespaces that are running out of space and take necessary actions to prevent data issues.

Locking and concurrency

Monitor locks and concurrency within the DB2 database. Identify any lock contention issues that could lead to performance degradation or data inconsistency. Track the number of lock timeouts and deadlocks to optimize transaction concurrency.

Backup and recovery

Monitor the backup and recovery processes of the DB2 database. Ensure that regular backups are performed successfully and monitor the backup completion status. Track recovery times in case of any database failures or data corruption.

Error and event logs

Monitor DB2 error logs and event logs to identify and resolve any issues or errors that occur within the database. Log and track error messages, warnings, and informational events for troubleshooting and proactive maintenance.

For basic monitoring of a single instance, Germain uses a regular database user account with CONNECT permissions.

In order to perform more in-depth monitoring, the database user needs to be granted additional permissions to execute queries against a series of system views and tables.

Please note that Germain can monitor any other DB2 tables (system or data) i.e. the above requirements are the bare minimum requirements yet can be extended to any other tables. Germain User permissions:
