| Metric | Explanation |
| Free Memory | The amount of physical memory available to the operating system, system library files, and applications. |
| Cache Hit Rate | How often the system accesses the CPU cache. |
| Page-outs/s | The rate at which pages were written to disk. |
| Page-ins/s | The rate at which pages were read from or written to the disk. |
| Page Free/s | The number of pages that are freed from memory each second. |
| Attaches/s | The number of pages that get attached to memory each second. |
| Page-out Requests/s | The number of requests to perform a write operation that occur each second. |
| Page-in reqs/s | The number of requests to perform a read operation that occur each second. |
| PageScans/s | The number of pages that are scanned each second. |
| PageFaults/s | The number of page faults that occur each second. |
| Software Locks/s | The number of software locks that are issued each second. |
| Virtual Faults/s | The number of virtual memory faults that occur each second. |
| Free Swap | The amount of available free swap space, as a percentage of total available free swap space. |
Disk
The Uptime Infrastructure Monitor agent uses the following commands to collect disk statistics:
...
| Metric | Explanation |
| Disk (Spindle) Name | The names of each disk on the system. |
| Usage (% Busy) | The percentage of time during which the disk drive is handling read or write requests. |
| Throughput (Blk/s) | The number of read and write operations on the disk that occur each second. |
| Read/Writes/s | The average number of bytes that have been transferred to or from the disk during write or read operations. |
| Average Queue Length | The number of threads that are waiting for processor time. |
| Average Service Time | The average amount of time, in milliseconds, that is required for a request to be carried out. |
| Average Wait Time | The average time, in milliseconds, that a transaction is waiting in a queue. The wait time is directly proportional to the length of the queue. |
Network
The Uptime Infrastructure Monitor agent uses the netstat -s command to collect network metrics from a Solaris server. Except for TCP re-transmits, the agent averages all statistics per interface. Other statistics (e.g. kbps, errors and collisions) are collected per interface by the kstat command.

| Metric | Explanation |
| PID | The unique identifier of a specific process. |
| PPID | The identifier of the process that the process that is currently running. |
| UID | A value that identifies the current user. |
| GID | A value that identifies a group of users. |
| Memory Consumed | The amount of memory that is being used by a process. |
| RSS | The amount of physical memory that is being used by a process. |
| CPU % Utilization by Process | The percentage of CPU time that is being used by individual processes. |
| Memory % Utilization by Process | The amount of physical memory that is being used by individual processes. |
| Process Start Time | The time at which the process started. |
| Process Run Time | The time at which the process started. |
| Number of Processes Running | The total number of processes that are currently running on the system. |
| Number of Blocked Processes | The total number of processes that are blocking resources. |
| Number of Waiting Processes | The total number of processes that are waiting to be executed by the CPU. |
| Execs per Second | The total number of system calls that are executed each second. |
| Process Creation Rate | The total number of processes that are being spawned over a specified time period. |
Workload
Workload statistics are sorted within Uptime Infrastructure Monitor's core but are the same 20 processes that were gathered from the Process method (see above). The workload processes gathered by the agent include user/group/process name and their individual statistics. The Uptime Infrastructure Monitor core then sorts based on the selected graph (e.g. user, group or process name).
