Capable of providing alerts on the need for Table Reorganization, Statistics Collection, and Database Backup Box Checked Box Checked

Capable of providing alerts for database files closed Box Checked Box Unchecked
Capable of providing alerts when an SQL or XQuery statement uses a high percentage of CPU, in the aggregate, compared to other statements, within a specified timeframe (for example, during the past 15 or 30 minutes)
*** REAL PROBLEM ***
Box Checked Box Unchecked
Capable of providing alerts if a table incurs an excessively high percentage of Read I/O, in the aggregate, compared to other tables. Box Checked Box Unchecked
Capable of providing alerts if "Table Rows Read per Transaction" breaches a defined threshold which would indicate excessive scans and CPU utilization are occuring.
*** REAL BIG PROBLEM ***
Box Checked Box Unchecked
Capable of providing alerts when an SQL or XQuery statement uses a high percentage of Sort Overflows or Sort Time, in the aggregate, compared to other statements, within a specified timeframe (for example, during the past 15 or 30 minutes) Box Checked Box Unchecked

Able to provide alerts if overall disk write time (OWMS) becomes too high for the database or a tablespace Box Checked Box Unchecked

Able to provide alerts if the Synchronous Read Percentage (SRP) is too low - indicating excessive asynchronous prefetch I/O and the likely need to create missing indexes or provide higher quality indexes. Box Checked Box Unchecked
Can provide alerts for poor XQuery performance including, but not limited to, a low XQuery bufferpool hit ratio or a low XQuery Synchronous Read Percentage Box Checked Box Unchecked
Can provide alerts if average lock wait time is too high, there have been too many lock escalations, there is insufficient Locklist memory, there are too many locks per transaction, or there are excessive lock timeouts. Box Checked Box Unchecked
Can provide alerts if Index Cluster Ratios are too low, table statistics are missing, or if Indexes are defined without the MINPCTUSED clause. Box Checked Box Unchecked
Can provide alerts if the average number of Hash Joins per Transaction is too high - indicating that indexes are missing and CPU utilization is too high. Box Checked Box Unchecked
Able to provide alerts if the Index Read Efficiency (IREF) metric is too high for the database, a database partition, or a SQL statement - indicating that costly scans are occuring and CPU utilization is too high Box Checked Box Unchecked
Capable of providing alerts if CPU Busy Percentage is too high on the server, or if the database server's paging rates are too high Box Checked Box Unchecked
Able to provide an alert if database transaction response time averages, during a recent time period, exceed a certain response time threshold. Simply stated, the ability to tell you if response times stink.
*** HUGE PROBLEM ***
Box Checked Box Unchecked
