Implemented features
Mail protocols implemented in Pulse - Monitoring Tool for JIRA allows you to test availability specified mail protocol. You can test if your mail service provider servers are alive or if your authorization data are correct.
Protocol settings
Pulse - Monitoring Tool for JIRA provide availability of sending receive retrieving emails. You can define:
- tested e -mail adrdress,
- "correct" response time,
- success service status strategy,
- timeout.
If timeout reached, and you still do NOT have response it means that your e-mail work incorectly e.g. you should check your domain name is pointing to the correct name servers where your email is hosted.
Timeout protect your service against the eternal waiting for response - after that period your service will be notified about unavailability and next test will be executed.
Service status strategy allows you to specify if: all or any of attempts succeded, we want use minimal, maximal or average test values to compare with yours.
Example
Below you can find sample of SMTP protocol configuration in PULSE - Monitoring Tool for JIRA.
There are few steps to take SMTP service test.They include:
- find mail server on specified host,
- check if specified server support encrypted connections (if checked),
- connect with correct authorization data and protocol port.
In case above we are using "at least one attempt was success" strategy. It means, we need only one attempt to be succeded to say that tested service is working correctly and feel free to check service status as "succeded". If remote mail server will NOT response until timeout (in this case 10 seconds) - service status will be checked as "failure". Also in case incorrect authorization data you will receive proper message.
