Re: TomEE management/administration applications

[exabrial12]

Grafana is great. I've used it in the past and liked it. If you have multiple
timeseries databases, it's ability to combine them is very handy.

Chronograf offers a similar feature set, but adds a some pre-built
dashboards for quite a few things... But the biggest selling point is the
Kapacitor integration. Kapacitor is an monitoring/alerting daemon. You write
TickScripts that watch the InfluxDB stream for certain conditions and can
take actions like alerting or even rectifying the issue. The TickScript
language is lambda/builder based so it's not incredibly hard to learn and
offers an immense amount of flexibility.

Attached: one of our generalized Chronograf TomEE dashboards:


 

I'm likely going to submit a patch Telegraf for Tomcat. TomEE needs to put a
"type" on some it's metrics (like am I monitoring a jms connection factory
or a datasource) to make an automatic dashboard, I'll probably get around
two writing a patch for that later. 

It's also worth noting that [I believe, correct me if I'm wrong] Tomitribe
offers an enhanced version of TomEE with metrics, and they've been super
busy working on getting MicroProfile health checks into TomEE 7.1.x/8.0.x.
It might be worth reaching out to them!

 Thanks Jonathan, brilliant!

We are doing kind of the same using jolokia --> telegraf --> influxdb -->
grafana.

Jonathan: in your opinion what would be the advantages of chronograf over
grafana? Looking forward for your blog post! :)

Thanks,

Luis

Great answer. Wondering if we could create some kind of a page on our
website with this kind of value?
What do you think?

Hi Sudhakar,

We don't have an OS/free console really worth it ATM I think - mainly
because our configuration stays simple enough to not require it. We have a
few JMX stuff but it depends what you are looking for.

Not sure there is a book going really further Tomcat administration and
tomee configuration but you can check our website at
http://tomee.apache.org/docs.html and ask any question you don't find an
answer to here.
