portcheck

Module monitors a remote TCP service.

Following charts are drawn per host:

1. Latency ms

• Time required to connect to a TCP port. Displays latency in 0.1 ms resolution. If the connection failed, the value is missing.

2. Status boolean

• Connection successful
• Could not create socket: possible DNS problems
• Connection refused: port not listening or blocked
• Connection timed out: host or port unreachable

configuration

server:
  host: 'dns or ip'     # required
  port: 22              # required
  timeout: 1            # optional
  update_every: 1       # optional

notes

• The error chart is intended for alarms, badges or for access via API.
• A system/service/firewall might block netdata's access if a portscan or similar is detected.
• Currently, the accuracy of the latency is low and should be used as reference only.
