check_db2_health is a plugin for Nagios that allows you to monitor DB2 database servers. Itcan operate in several modes: measuring how long it takes to connect and log in; display the number of connected users; display percentage of synchronous reads (SRP); display the percentage of asynchronous writes; display hit ratio in Buffer Pools, or only in Data Pages or Index Pages; display the percentage of SELECT that use an index; display the number of deadlocks per second; display the number of lock requests per second that could not be satisfied; display the fraction of time which was spent waiting for locks; display used space in a database or tablespace; display free space in a tablespace (in contrast to the previous mode, you can use units (MB, GB) for the thresholds); or display used space in a database log.
