      kpi: Add support for QCI to Measurements · ffffb933
      Kirill Smelkov authored
      Previously for Measurement fields with .QCI or .CAUSE suffix we had only
      the .sum value and no per-QCI nor per-CAUSE values. In other words
      support for QCI and CAUSE was stub. In this patch we add support for
      QCI: every field X.QCI is now automatically expanded into X[256] array
      and X.sum . For convenience we also provide X.<qci> aliases that alias
      X[qci]. For example field DRB.IPVolDl.9 aliases 9'th element of
      DRB.IPVolDl array.
      
      We will need QCI support for E-UTRAN IP Throughput KPI which is required
      to provide resulting values for every QCI individually.
      
      CAUSE support remains stub for now.

      kpi: Fix Σqci and Σcause when invoked on NA data · 6eccb446
      Kirill Smelkov authored
      There was a thinko that led to returning 0 instead of NA when there are
      not .QCI or .CAUSE fields except .sum . Without added fix, e.g.
      
      	Σqci(Measurement(), 'ERAB.EstabInitAttNbr.QCI')
      
      was returning 0 instead of NA.
      
      -> Fix it.

      kpi: Fix naming of Measurement fields related to IP Throughput · 762153ab
      Kirill Smelkov authored
          DRB.IPThpVol   ->  DRB.IPVol	(no "Thp" inside)
          DRB.IPThpTime  ->  DRB.IPTime	(no "Thp" inside
      
      TS 32.450 and TS 32.425 defines those names as in corrected variants -
      please see corresponding references in the code for details.
      
      It was my thinko in dc1d5481 (kpi: Start of the package) to use "Thp" in
      the names.

      amari.kpi: New package with driver for Amarisoft LTE stack to retrieve... · 71087f67
      Kirill Smelkov authored
      amari.kpi: New package with driver for Amarisoft LTE stack to retrieve KPI-related measurements from logs
      
      amari.kpi provides LogMeasure that takes enb.xlog (TODO and enb.log) as
      input, and produces kpi.Measurements on output.
      
          enb.xlog     ─────────
          ─────────>  │   Log   │
                      │         │ ────> []kpi.Measurement
          ─────────>  │ Measure │
          enb.log      ─────────
      
      We read log data organizing periods around stats queries, and for now we
      build Measurement from stats' counters. To do so we take δ(stats_prev, stat)
      and process it mapping Amarisoft counters to 3GPP ones specified by
      kpi.Measurement.
      
      We emit measurement X after reading stats X+2 - i.e. we emit measurement
      for a period after reading data covering _next_ period. It is organized
      this way to account for init/fini correction:
      
                   fini adjust
                  -------------
                 '             '
           Sx    v     Sx+1    '   Sx+2
        ────|───────────|───────────|────
             Measurement Measurement
                  X          X+1
      
      This approach has following limitations:
      
      - for most of the counters there is no direct mapping in between
        Amarisoft and 3GPP. For example we currently use s1_erab_setup_request for
        ERAB.EstabAddAtt.sum, but this mapping is not strictly correct and will
        break if corresponding S1 E-RAB SETUP REQUEST message contains multiple
        ERABs. The code has corresponding FIXME marks where such approximations
        are used.
      
      - it is not possible to implement init/fini correction precisely. From
        aggregated statistics we only get total amount for a fini value for a
        period - without knowing which part of it corresponds to init events
        from previous period, and which part to init events from current one.
        With that it is only possible to make a reasonable guess and try to
        preserve statistical properties, but not more. See m_initfini in the
        code for details.
      
      - it is possible to handle eNB with single cell only. This limitation
        comes from the fact that in Amarisoft LTE stack S1-related counters
        come as "globals" ones, while e.g. RRC-related counters are "per-cell".
        It is thus not possible to see how much S1 connection establishments
        are associated with one particular cell if there are several of them.
      
      TODO also parse enb.log to fix those issues.

      kpi: Start of the package · dc1d5481
      Kirill Smelkov authored
      Start the package to process measurements and compute KPIs from them.
      
      In this patch we add kpi.Measurement - a central part to represent
      measurement results in intermediate generic form. kpi.Measurement will
      be used by both KPI calculator, and by drivers for particular LTE stacks
      to provide their KPI-related data in this uniform common format.
      
      kpi.Measurement also establishes semantic for such measurement results
      to be followed by drivers. The semantic is stated in kpi.Measurement
      docstring and in comment for every field. Also in particular, according
      to TS 32.401 and common sense, measurement data are required to be
      correctly accounted for initiation/termination events to avoid
      discrepancies. Quoting kpi.Measurement documentation:
      
          Important note (init/fini correction):
      
            Termination events should be counted in the same granularity period, where
            corresponding initiation event occurred, even if termination event happens
            _after_ granularity period covering the initiation event. For example in the
            following illustration "ConnEstab Success" event should be counted in the
            same granularity period 1 as "ConnEstab Initiate" event:
      
                           -----------------------
                          '                       '
                  | p e r ' i o d 1       | p e r ' i o d 2    |
                  |       '               |       v            |
              ────'───────x───────────────'───────x────────────'────────────>
                      ConnEstab               ConnEstab                time
                      Initiate                 Success
      
            This preserves invariant that N(initiations) is always ≥ N(results) and
            goes in line with what TS 32.401 4.3.2 "Perceived accuracy -> Same period
            for the same two events" requires.
      
      kpi.Measurement comes accompanied by kpi.MeasurementLog which in essence
      is array of kpi.Measurements.
      
      We will use kpi.Measurement and kpi.MeasurementLog in later patches to
      both provide Amarisoft-specific data in this common format, and to
      compute KPIs from it.

      amari.xlog: Document xlog protocol · 22292b62

      Document kind of messages and events that could be emitted by xlog.
      
      The messages come from Amarisoft software directly, but events are

      Kirill Smelkov authored
      The time emitted in messages by Amarisoft is in seconds. It also makes
      sense to emit meta/event times in seconds as well for uniformity.
      
      This is backward-incompatible change, but it should be ok at this early time.

      amari.xlog: Flush each emitted line · 9c8da27f
      Kirill Smelkov authored
      xlog logging is kind of slow - usually it comes once per several seconds
      or once per minute. And without flushing many entries can remain sitting
      up in the file buffer in userspace without being conveyed to OS kernel.
      Which is not very convenient because in such situation we cannot make good
      use of tools like `tail -f`.
      
      Since flushing is relatively cheap operation - it is just one write
      syscall - let's do it after every emitted line. The write syscall does
      not force data to be synced to disk, so it should not slow things down,
      but make it convenient to have latest logs right away in the filesystem
      view.

      amari: Fix Conn rx timeout handling · 8f94b47d
      Kirill Smelkov authored
      Conn multiplexes many requests/responses over single WebSocket
      connection. To do so it organizes dedicated receive thread that
      continuously receives messages from underlying websocket connection and
      dispatches received replies back to threads that issued corresponding requests.
      
      An rx timeout in that receive thread is thus not something unexpected -
      it can happen e.g. if there is simply no requests sent. But I missed
      that in 61ad9032 (amari: Add functionality to interoperate with an
      Amarisoft LTE service via WebSocket) and implicitly did not ignored such
      global rx timeout. As the result `amari xlog` does not work properly if
      period of requests is greater than timeout value, for example:
      
              $ xamari xlog ws://localhost:9001 ue_get/30s
              {"meta": {"event": "start", "time": 1670588996.0623107, "generator": "xlog ws://localhost:9001 ue_get[]/30.0s"}}
              {"meta": {"event": "service attach", "time": 1670588996.1852894, "srv_name": "ENB", "srv_type": "ENB", "srv_version": "2022-12-01"}}
              {"message":"config_get", ...}
        note  {"message":"ue_get","ue_list":[],"message_id":2,"time":3045.323,"utc":1670588996.423}
        ----> {"meta": {"event": "service detach", "time": 1670589026.3569217, "srv_name": "ENB", "srv_type": "ENB", "srv_version": "2022-12-01", "reason": "timed out"}}
              {"meta": {"event": "service attach", "time": 1670589029.485363, "srv_name": "ENB", "srv_type": "ENB", "srv_version": "2022-12-01"}}
              {"message":"config_get", ...}
              {"message":"ue_get","ue_list":[],"message_id":2,"time":3078.606,"utc":1670589029.706}
              ...
      
      -> Fix it by ignoring global rx timeout.
      
      NOTE: we must also add manual handling of per-request timeout when
      waiting for corresponding reply. If we don't do that a situation where
      particular reply does not come back, but replies for other requests are
      coming back ok, will never be detected.
      
      Here is how fixed version works now:
      
              $ xamari xlog ws://localhost:9001 ue_get/30s
              {"meta": {"event": "start", "time": 1670589223.0339117, "generator": "xlog ws://localhost:9001 ue_get[]/30.0s"}}
              {"meta": {"event": "service attach", "time": 1670589223.1970558, "srv_name": "ENB", "srv_type": "ENB", "srv_version": "2022-12-01"}}
              {"message":"config_get", ...}
              {"message":"ue_get","ue_list":[],"message_id":2,"time":3272.292,"utc":1670589223.391}
              {"message":"ue_get","ue_list":[],"message_id":3,"time":3302.274,"utc":1670589253.373}
              {"message":"ue_get","ue_list":[],"message_id":4,"time":3332.266,"utc":1670589283.365}
              ...
      
      Note that ue_get messages are coming sequentially and there is no
      "service detach" event, that was artificially popping up due to wrong
      timeout handling.

      amari.xlog: Begin emitting queries right after startup · 134f3a1e
      Kirill Smelkov authored
      For example with `stats/100s` stats query is emitted every 100 seconds,
      but currently it will be first emitted only after waiting for 100
      seconds after `xamari xlog` startup, or after reconnection to eNB if eNB
      itself was restarted. And this way it will be hard to interpret obtained
      numbers in relation to last 100s time interval.
      
      -> Start emitting queries right after reconnection / xlog start, so that
      we see the values as observed at the beginning, and can compare result

      amari.xlog: Initial draft · e0cc8a38
      Kirill Smelkov authored
      `xamari xlog` can be used to maintin extra log for an Amarisoft LTE
      service: in addition to native logs, xlog contains results of periodic
      queries done via WebSocket. For example with the following aguments
      
      	xamari xlog <wsuri>  stats/10s ue_get/3s erab_get/3s
      
      xlog will emit results of stats query - every 10 seconds, results from
      ue_get query - every 3 seconds, and similarly for erab_get query.
      
      The results are saved into xlog in JSON Lines format for easy future
      processing. For the reference below is a copy of corresponding help
      entries:
      
          xlte$ xamari help xlog
          Usage: xamari xlog [OPTIONS] <wsuri> <logspec>+
          Maintain extra log for a service.
      
          The service is queried periodically according to logspec and results are saved
          in JSON format to a file (see 'xamari help jsonlog').
      
          <wsuri> is URI (see 'xamari help websock') of an Amarisoft-service.
          <logspec> is specification of what to log. It has the following parts:
      
              <query>[<options>]/<period>
      
          The query specifies a message, that should be used to query service. For
          example "stats", "ue_get", "erab_get", ... Query part is mandatory.
      
          Options specifies additional flags for the query. Options part can be omitted.
      
          Period specifies periodicity of how often the service should be queried.
          Period is optional and defaults to 60 seconds.
      
          Example for <logspec>+:
      
              stats[samples,rf]/30s  ue_get[stats]  erab_get/10s  qos_flow_get
      
          Options:
      
              -h  --help            show this help
      
          xlte$ xamari help jsonlog
          Some commands produce logs with JSON entries. Such logs are organized with JSON
          Lines format(*) with each entry occupying one line.
      
          Logs in JSON Lines format are handy to exchange in between programs, and with
          corresponding tools, e.g. jq(+), they can be also displayed in human-readable
          form and inspected quickly.

      amari: Add functionality to interoperate with an Amarisoft LTE service via WebSocket. · 61ad9032
      Kirill Smelkov authored
      - amari.connect() connects to a service and returns Conn.
      - Conn can be used to issue requests, receive replies and (TODO) event
        notifications. Several requests could be issued simultaneously and
        handled in parallel.
