remotehosts - monitor remote simplemonitors
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This monitor inspects the state of the local simplemonitor instance to check expected remotes are sending data to it.
.. warning:: At startup, simplemonitor doesn't know any remote hosts. They'll only be known once they've connected once, which means this monitor may fail initially. Consider using the ``tolerance`` option to reduce false positives.
.. confval:: hosts
:type: comma-separated list of string
:required: true
the remote hosts to expect. This will need to be a list of IPs as simplemontitor doesn't reverse-lookup connections. However, if you want to give names to your remotes, you can use the ``custom_name`` property of the network logger and then specify that here.
.. confval:: max_age
:type: int
:required: false
:default: 300
the maximum time in seconds since a remote host last contacted us before it's considered missing
.. note:: Note that depending on your OS/configuration, you may see IPv4 IPs with a ``::ffff:`` prefix.
.. tip:: This monitor reports both missing and unexpected remotes, so you can use that to see what should go in your configuration.
