Lists and describes the key performance indicators (KPIs) that provide the statistics displayed on Adaptive Server screens and charts in Sybase Control Center.
Each Adaptive Server data collection includes a subset of the KPIs listed here.

| Load Score for Logical Cluster Workload | This KPI is collected separately for each cluster workload and is used to generate the load score chart on the Workload screen. | |
| Run Queue Length for Logical Cluster Workload | This KPI is collected separately for each cluster workload and is used to generate the run queue length chart on the Workload screen. | |
| Data Caches | Cache Hit Ratio | Hit ratio in the data cache during the current collection cycle. |
| Number of Cache Misses | Number of cache misses(or reads into the cache from the disk) during the current collection cycle. | |
| Number of Cache Searches | Number of cache searches during the current collection cycle. | |
| Devices | Device APF Reads | Rate per second of asynchronous pre-fetch read operations on this device. |
| Device Free Space | Total amount of free space, in megabytes, on this device. | |
| Device Space Usage | Total amount of space on this device, in megabytes, that is used by processes. | |
| Device IO Rate | Rate of I/O operations per second on this device. | |
| Device IO Response Time | Response time, in milliseconds, for I/O operations performed on this device. | |
| Engines | Engine CPU Utilization | Percentage of CPU cycles used by this Adaptive Server engine. |
| Logical Clusters | Active Connections in Logical Cluster | Number of active connections using the Logical Cluster at the time of collection. This KPI is collected separately for each Logical Cluster. |
| Number of Failover Instances in Logical Cluster | Number of instance that are failed-over in the currently active Logical Cluster. This KPI is collected separately for each logical cluster. | |
| Segments | Segment Free Space | Amount, in megabytes, of free space in the segment. This KPI is collected separately for each segment. |
| Segment Space Usage | Change, in megabytes, in the amount of space used by this segment since the last refresh. | |
| Server | Average Blocked Process Wait Time | Average time, in milliseconds, that the current blocked processes have waited. |
| Number of Address Locks | Number of address-level locks server-wide. | |
| Number of Blocked Processes | Number of currently blocked processes that have been blocked for more than 5 seconds. (The Heat Chart uses this metric to display server status.) | |
| Number of Bytes Received in Network IO | Number of bytes received during the current collection cycle. | |
| Number of Bytes Sent in Network IO | Number of bytes sent during the current collection cycle. | |
| Number of Deadlocks | Number of deadlocks on the server since the most recent execution of the collection. | |
| Number of Locks | Total number of active locks of all types on the server. | |
| Number of Packets Received in Network IO | Number of packets received during the current collection cycle. | |
| Number of Packets Sent in Network IO | Number of packets sent during the current collection cycle. | |
| Number of Page Locks | Number of page-level locks server-wide. | |
| Number of Row Locks | Number of row-level locks server-wide. | |
| Number of Suspended Processes | Number of processes that are currently suspended. (The Heat Chart uses this metric to display server status.) | |
| Number of Table Locks | Number of table-level locks server-wide. | |
| Number of Transactions | Total number of transactions during the current collection cycle. Note: This KPI is available only on Adaptive Server versions 15.0.3 Cluster Edition and 15.0.3 ESD #3, and later.
