    Statistics

    WebApp Secure software allows for standard SNMP system monitoring. All statistics available on a typical Linux system would be available to WebApp Secure through standard system SNMP mibs. In addition, WebApp Secure currently offers six types of systems statistics in a form of graphs. They include CPU Utilization, CPU Load Average, Memory Utilization, Network Traffic, Proxy Connection and Proxy Requests. They can be accessed through System Status button in the main menu of the Configuration management interface. Depending on the desired level of details, the statistics can be viewed for the Last Hour, Last 12 Hours, Last Day, Last Week and, finally, Last Month (always last 30 days).

    Below are the details of the statistics that are available for each type:

    CPU Utilization

    • Wait - Percentage of CPU time spent in wait (on disk)
    • Softirq - Percentage of CPU time spent handling software interrupts
    • System - Percentage of CPU time spent in kernel space
    • User - Percentage of CPU time spent in user space

    CPU Utilization

    CPU Load Average

    • 1 min - CPU Load for the last minute
    • 10 min - CPU Load for the last 10 minutes
    • 15 min - CPU Load for the last 15 minutes

    Memory Utilization

    • Used - Amount of memory used
    • Free - Amount of memory free
    • Free - Amount of memory free

    Network Traffic

    • Outbound - Amount of traffic leaving the box
    • Inbound - Amount of traffic entering the box

    Network Traffic

    Proxy Connections

    • Reading - Number of TCP connections reading data
    • Waiting - Number of TCP connections waiting
    • Writing - Number of TCP connection writing Proxy

    Proxy Requests

    • Requests - Current number of HTTP/HTTPS requests being processed

    Proxy Requests

    Master - Slave Mode–In the case of the appliance running in multi-server mode, the systems statistics will show details for each node in the cluster as well as the key cumulative data across the entire cluster. Each system will be presented as a tab in the Web UI's System Status page with the Aggregate tab being first. The Aggregate tab always shows CPU Utilization, Network traffic, Proxy connections and Proxy requests collected from the entire active WebApp Secure cluster.
