问题 Suppose I have an ec2 instance with service /etc/init/my_service.conf with contents script exec my_exec end script How can I monitor that ec2 instance such that if my_service stopped running I can act on it? 回答1: You can publish a custom metric to CloudWatch in the form of a "heart beat". Have a small script running via cron on your server checking the process list to see whether my_service is running and if it is, make a put-metric-data call to CloudWatch. The metric could be as simple as

问题 With this code, and using the FilterLogEvents function I am getting the logs from Cloudwatch that match these parameters: { "endTime": number, "filterPattern": "string", "interleaved": boolean, "limit": number, "logGroupName": "string", "logStreamNames": [ "string" ], "nextToken": "string", "startTime": number } The code: response = self.cloudWatchLogs.filter_log_events(**kwargs) I defined filterPattern to be " ERROR " so that I can get all the error logs.

Here is how you can solve it, Create a Lambda/ cron job that can poll the queues, get ApproximateNumberOfMessages on each queue and update the total messages to a custom Cloudwatch Metric. QueueAttributes:

问题 I am trying to get an AWS Lambda function to run whenever a new image is pushed to an AWS container registry. I have created and tested the function which works fine. I have then created a simple CloudWatch event rule with the pattern: { "source": [ "aws.ecr" ] } which I believe will trigger on any event from ECR. The rule has a target of the lambda function. The problem is the function is not called when a new image is pushed to the registry (or deleted etc). Nothing appears in the
