This graph shows the number of concurrent authenticated sessions as well as the total number of allocated sessions on Airlock Gateway.

This graph shows the number of processes running on a CPU, waiting for a free CPU, or waiting for I/O operations to complete. This is a basic indicator of the overall CPU load. If long term trends indicate increasing figures, more or faster CPUs will eventually be necessary.

This graph shows the number of front listener processes and the total number of processes. The number of listener processes should be less than the number of sessions. Under heavy load this number may increase up to the number of sessions.

This graph shows the number of active filter and session engines.

This graph shows the percentage of CPU time being spent in various states. The most important states are "User" (executing user processes), "System" (executing system processes), and "I/O Wait" (waiting for I/O operations to complete). If long term trends indicate increasing figures, more or faster CPUs will eventually be necessary. Increased I/O wait percentages can be seen when disk mirroring is in progress.

This graph shows the rate at which new processes are created. This graph is mostly for development and debugging purposes.

This graph shows the number of context switches per second.

This graph shows the uptime of the system in days. There are different colors for active, passive and offline times.

This graph shows the percentage of used disk space allocated to files on the mounted partitions / and /var.

This graph shows the number of clients (SG processes) connected to the session store.

This graph shows the number of keys in the session store.

This graph shows the number of session store operations per second. This is an indicator for the load of the session store.
