Logging and monitoring in Amazon IoT Greengrass
Monitoring is an important part of maintaining the reliability, availability, and performance of Amazon IoT Greengrass and your Amazon solutions. You should collect monitoring data from all parts of your Amazon solution so that you can more easily debug a multi-point failure, if one occurs. Before you start monitoring Amazon IoT Greengrass, you should create a monitoring plan that includes answers to the following questions:
-
What are your monitoring goals?
-
Which resources will you monitor?
-
How often will you monitor these resources?
-
Which monitoring tools will you use?
-
Who will perform the monitoring tasks?
-
Who should be notified when something goes wrong?
