Missed clients

[Metrics Searcher]

Hello.

Could you please give me a clue how to find lost clients from the OpenVPN server. The metric looks like below:

openvpn_server_client_received_bytes_total{common_name="ID",connection_time="1591021598",instance="server.com:9176",job="server.com",real_address="1.1.1.1:56228",status_path="/etc/openvpn/openvpn-status.log",username="ID",virtual_address="IP"}

I'd like to get all clients which doesn't any update during an hour or a day. I suppose I should to use something like "absent_over_time", but as I understand it works only by a job of instance, not with the metric.

While it is not advised to put so much details in metrics labels, here
is how you could do that:

rate(openvpn_server_client_received_bytes_total[1d]) == 0
or
(
openvpn_server_client_received_bytes_total offset 1d unless
openvpn_server_client_received_bytes_total
)
