I have configured several metric filters to monitor the contents of a certain file on my EC2 instance.
I followed the documentation. The metric filters are configured with "1" as the metric value and "0" as the default value. The former should be sent to the metric when the string pattern is found in the log, the latter should be sent if the pattern is not found.
In the Cloudwatch metrics page, I can see that no values are being published (there should be 0s present). What am I missing?
EDIT: looks like 0 is being published but only every 30 min. Why is that?
