Methods (to be applied on instances)

  • describe (scripted, public)

     <instance of ns::stats::Collector[i]> describe [ -server server ]

    Return a dictionary describing the NaviServer process, virtual servers, connection pools and network drivers. An optional server argument restricts virtual-server data; process-wide information retains its process scope. Availability fields identify optional information that could not be collected. Does not start sampling or modify the sampling baseline.

    Switches:
    -server (optional)

    Testcases:
    No testcase defined.

  • snapshot (scripted, public)

     <instance of ns::stats::Collector[i]> snapshot [ -server server ]

    Collect current gauges, cumulative counters, allocator statistics and thread CPU times into a timestamped dictionary. The timestamp is in epoch microseconds; collectionSeconds records collection duration. The observations are collected sequentially and do not constitute an atomic snapshot of the entire process. An optional server argument restricts virtual-server data. Does not publish a sample or advance the sampling baseline.

    Switches:
    -server (optional)

    Testcases:
    No testcase defined.
