Key findings

2 key findings

TCP port reachability

Warning

Measurement: service.example.com:443: 1.24 s

Meaning: The TCP check reports a warning for connection setup time. A slow connection does not mean the port is unreachable.

Why it matters: The Linux collector flags successful connections taking more than 1 second as warnings. This measurement alone does not establish a cause.

Next step: Repeat the TCP check for the same target and port. Compare connection times with a working device on the same network while the problem occurs.

Ping: 198.51.100.42

Packet loss

Measurement: 1 measurement · sent 10 · received 9 · lost 1 · 10.00 % packet loss

Meaning: The recorded ping invocations show packet loss or an elevated response time for this target.

Why it matters: This finding applies only to the recorded target and measurement series; packet loss alone does not identify the cause.

Next step: Repeat ping to this target: ping 198.51.100.42
