salt.beacons.napalm_beacon  Watch NAPALM functions and fire events on specific triggers  New in version 2018.3.0.   Note The NAPALM beacon only works only when running under a regular Minion or a Proxy Minion, managed via NAPALM. Check the documentation for the NAPALM proxy module.  The configuration accepts a list of Salt functions to be invoked, and the corresponding output hierarchy that should be matched against. To invoke a function with certain arguments, they can be specified using the _args key, or _kwargs for more specific key-value arguments. The match structure follows the output hierarchy of the NAPALM functions, under the out key. For example, the following is normal structure returned by the ntp.stats execution function: {
    "comment": "",
    "result": true,
    "out": [
        {
            "referenceid": ".GPSs.",
            "remote": "818-558-2076",
            "synchronized": true,
            "reachability": 377,
            "offset": 0.461,
            "when": "860",
            "delay": 143.606,
            "hostpoll": 1024,
            "stratum": 1,
            "jitter": 0.027,
            "type": "-"
        },
        {
            "referenceid": ".INIT.",
            "remote": "818-558-2076",
            "synchronized": false,
            "reachability": 0,
            "offset": 0.0,
            "when": "-",
            "delay": 0.0,
            "hostpoll": 1024,
            "stratum": 16,
            "jitter": 4000.0,
            "type": "-"
        }
    ]
} In order to fire events when the synchronization is lost with one of the NTP peers, e.g., 818-558-2076, we can match it explicitly as: ntp.stats:
  remote: 818-558-2076
  synchronized: false There is one single nesting level, as the output of ntp.stats is just a list of dictionaries, and this beacon will compare each dictionary from the list with the structure examplified above.  Note When we want to match on any element at a certain level, we can configure * to match anything.  Considering a more complex structure consisting on multiple nested levels, e.g., the output of the bgp.neighbors execution function, to check when any neighbor from the global routing table is down, the match structure would have the format: bgp.neighbors:
  global:
    '*':
      up: false The match structure above will match any BGP neighbor, with any network (* matches any AS number), under the global VRF. In other words, this beacon will push an event on the Salt bus when there's a BGP neighbor down. The right operand can also accept mathematical operations (i.e., <, <=, !=, >, >= etc.) when comparing numerical values. Configuration Example: beacons:
  napalm:
    - net.interfaces:
        # fire events when any interfaces is down
        '*':
          is_up: false
    - net.interfaces:
        # fire events only when the xe-0/0/0 interface is down
        'xe-0/0/0':
          is_up: false
    - ntp.stats:
        # fire when there's any NTP peer unsynchornized
        synchronized: false
    - ntp.stats:
        # fire only when the synchronization
        # with with the 818-558-2076 NTP server is lost
        _args:
          - 818-558-2076
        synchronized: false
    - ntp.stats:
        # fire only when there's a NTP peer with
        # synchronization stratum > 5
        stratum: '> 5' Event structure example: {
    "_stamp": "2017-09-05T09:51:09.377202",
    "args": [],
    "data": {
        "comment": "",
        "out": [
            {
                "delay": 0.0,
                "hostpoll": 1024,
                "jitter": 4000.0,
                "offset": 0.0,
                "reachability": 0,
                "referenceid": ".INIT.",
                "remote": "818-558-2076",
                "stratum": 16,
                "synchronized": false,
                "type": "-",
                "when": "-"
            }
        ],
        "result": true
    },
    "fun": "ntp.stats",
    "id": "edge01.bjm01",
    "kwargs": {},
    "match": {
        "stratum": "> 5"
    }
} The event examplified above has been fired when the device identified by the Minion id edge01.bjm01 has been synchronized with a NTP server at a stratum level greater than 5.   salt.beacons.napalm_beacon.beacon(config)
