Prometheus statistics

    Felix specific

    Felix exports a number of Prometheus metrics. The current set is as follows. Since some metrics are tied to particular implementation choices inside Felix we can’t make any hard guarantees that metrics will persist across releases. However, we aim not to make any spurious changes to existing metrics.

    Example response:

    1. # TYPE felix_active_local_endpoints gauge
    2. felix_active_local_endpoints 91
    3. # HELP felix_active_local_policies Number of active policies on this host.
    4. # TYPE felix_active_local_policies gauge
    5. # HELP felix_active_local_selectors Number of active selectors on this host.
    6. # TYPE felix_active_local_selectors gauge
    7. felix_active_local_selectors 82
    8. ...

    CPU / memory metrics
