You can monitor the status of your custom application’s port using the TCP check. This check will routinely connect to the designated port and send Sysdig Monitor a simple on/off metric and response time.
This page describes the default configuration settings, how to edit the configuration to collect additional information, the metrics available for integration, and a sample result in the Sysdig Monitor UI.
TCP Application Setup
Any application listening on a TCP port can be monitored with
Sysdig Agent Configuration
Review how to Edit dragent.yaml to Integrate or Modify Application Checks.
No default configuration is provided in the default settings file; you
must add the entries in Example 1 to the user settings config file
Remember! Never edit
dragent.default.yaml directly; always edit
- name: tcp_check check_module: tcp_check pattern: comm: httpd arg: DFOREGROUND conf: port: 80 collect_response_time: true
This example shows monitoring a TCP check on an Apache process running on the host on port 80.
comm: is the command for running the Apache server on port 80.
If you want the response time for your port, meaning the amount of time
the process takes to accept the connection, you can add the
collect_response_time: true parameter under the
section and the additional metric
appear in the Metrics list.
Do not use
port: under the
pattern: section in this case,
because if the process is not listening it will not be matched and the
metric will not be sent to Sysdig Monitor.
The response time of a given host and TCP port, tagged with url, e.g. 'url:192.168.1.100:22'.
