TCP Connection

The tcp_connect plugin is used to identify if a host or ip is listening on a specified port. This is a simple check that is either OK for successful connections or CRITICAL for unsuccessful connections.

Runbook Example

The below is an example of using the network/tcp_connect health check in a runbook.

    execute_from: target
    type: plugin
    plugin: network/tcp_connect.py
    args: --host=localhost --port 3306

This plugin can be executed from either target or remote depending on the target being monitored.

Required arguments

The network/tcp_connect plugin requires 2 arguments.

args: -i <ip or hostname> -p <port> [-t <timeout value>]

The third value -t is an optional value, default is 5 seconds.
