Tomcat and CLoudWatch
Is anyone successfully monitoring Tomcat JMX beans on Amazon
CloudWatch? This shouldn't be that difficult. But we are hitting a
brick wall. Can't get anything to work that is recommended on forums.
Thx

Seems like fluentd would be another approach. I haven't tried it yet,
but the following links look promising.
Cloudwatch - albeit with a Kubernetes cluster
https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Container-Insights-setup-logs.html
Fluentd JMX plugin
https://github.com/hidsuzuk/fluent-plugin-jmx/blob/master/README.md
This looks workable, although it may be a bit heavy for a per-EC2
implementation.
I'm slowly working on dockerizing and containerizing a bunch of
applications running on Tomcat. This is the monitoring approach that I'm
considering.
. . . just my two cents

Hey Chris,
I've been working with Jerry on this. What I had found was to use Collectd
with the java and genericJMX plugins to gather the Mbeans i wanted to send.
After that there was the options of either using a cloudwatchPlugin
<https://github.com/awslabs/collectd-cloudwatch> for collectd or using the
AWS Cloudwatch agent to collect the metrics from collectd and send those to
cloudwatch. I've been able to get basic ec2 metrics (memory-free,
memory-percent-used, disk-used) from both of those angles but neither one
has let me send the JMX to cloudwatch. I don't seem to be getting any error
messages from either of them and they both tell me they're running.
