SMON checks port availability by sending TCP/UDP requests to the specified port. The availability status will be displayed in the box after a response is received from the server:
You can also configure notifications to receive warning messages if the specified port becomes unavailable. To do this, select the desired Telegram, Slack, PagerDuty, and/or Mattermost channel when adding a new check.
SMON sends an HTTP(S) request to the specified address (including the URI and port, if necessary) to check the HTTP status. To enable this feature, select the HTTP(s) option in the "Checking" field. You can also select the HTTP method for checks in the "HTTP method" field.
A warning message may be sent if the response code is anything other than 200. Additionally, warning and critical messages will be sent if the SSL certificate is about to expire.
SMON sends an HTTP(S) request to the specified address and checks the response body for the words listed in the Body field. If the response body does not contain the specified words, a warning message may be sent.
You can find events detected by the SMON service in the Monitoring => SMON: history section. This page includes the following information:
- The logging level
- The DNS name or IP address of the host
- The port number on which the event occurred
- A brief description of the event
- The date and time of event detection
You can view the history for all hosts or for a specific host. To view the event history for a specific host, type the host name or IP address in the "Search" field in the upper right corner, or click on the host's name in the list.
The status page allows you to collect checks of your choice and share them with your colleagues, clients, or monitoring team. Once you create a page and send them the link, they will be able to monitor the status of the services.
To create a new status page, click Create status page and fill out the settings in the dialog box as desired.
SMON Agent is a monitoring program installed on your server that performs interval checks to monitor your services from various worldwide locations and collect statistical information.
