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.

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.

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.
