Crash after running for several days

vaping version: 1.4.2 pypy version: 7.3.5 (python 3.7.10) fping version: 3.10

vaping config:

probes:
  - name: latency
    type: std_fping
    output:
      - prometheus
    testing_hosts:
      hosts:
        - host: 1.1.1.1
          name: Cloudflare DNS
        # few internal hosts omitted
plugins:
  - name: std_fping
    type: fping
    count: 10
    interval: 3s
    output:
      - prometheus
  - name: prometheus
    type: prometheus
    port: 9090

After running fine for several days, crashes and outputs the following exception:

vaping.daemon 'NoneType' object has no attribute 'get' daemon.py:214
PidFile <pid.posix.PidFile object at 0x00007fe8501e2560> closing pidfile: /root/vaping.pid base.py:220
vaping.daemon stopping prometheus daemon.py:254
vaping.daemon stopping latency daemon.py:254
PidFile <pid.posix.PidFile object at 0x00007fe8501e2560> closing pidfile: /root/vaping.pid base.py:220

Has currently happened twice now, but since I normally redirect all the debug output (due to #88) I was not able to get the exception output for the prior crash. Restarted it again and will continue logging the debug output for now.

Just as an update… so far so good after patching the prometheus plugin.

No, the implementation emit in init.py also extracts each element of the "data" list just as prometheus.py. The problem here is that the third party plugin that you are using is reimplementing emit and is thereby totally ignoring my patch.
