| April 26, 2016

managecat-and-jelastic logoLast week we've conducted the joint webinar - ManageCat for Monitoring Tomcat and TomEE Servers in the Jelastic Cloud. The webinar was presented by Gurkan Erdogdu, founder and CTO of ManageCat and Ihor Kolodyuk, technical director at Jelastic.

During the webinar, the panelists showed how to install ManageCat just in one click in Jelastic Cloud, demonstrated how to make optimal application configurations for monitoring your Tomcat and TomEE servers and how to automate tracking with a set of triggers for the further troubleshooting.image01

We were happy to announce the special offer from ManageCat - for all the attendees of the webinar, ManageCat team will double the amount of the registered servers (with max 10 free server agent). For example, if you buy 3 servers, ManageCat provides you 6 servers license!

Also, you are welcome to review the most interesting questions and answers discussed during the webinar:

1. What kind of servers does the ManageCat support?

Gurkan: ManageCat supports ApacheTomcat server, Apache TomEE, Apache Web servers and recently we`ve added Docker containers.image00

2. Can I perform any group actions using ManageCat  (update jar library for all of my Tomcat instances or fix a configuration file for all of them)?

Ihor: Yes,this can be done in both ways - you can do it through the Jelastic platform or ManageCat.

3. Is there any functional difference between ManageCat Tomcat and TomEE agents?

Gurkan: Actually, there's no so much functional difference. But for TomEE, if there exist any EJB deployment, you can see the EJB monitoring information as well as TomEE specific EJB container runtime information view. So the agent is the same, the only difference is in some extra TomEE features.

4. After automatic horizontal scaling, will my new instances appear in ManageCat panel automatically?

Ihor: When the instances in Jelastic are scaled automatically, for example, from 10 to 100 or even more, all of them will be automatically registered in ManageCat service.image02

The thing is, that when Jelastic performs scale-out , it creates a clone of the primary master node and adds it to an existing cluster. The cloned instance will be absolutely the same as the primary one, including ManageCat agent running inside. Moreover, if you install your add-on on top of already existing clusters, all of your nodes in this cluster will be transferred to your ManageCat panel.

5. Can I also use ManageCat in private on-premise environments?

Gurkan: Yes, it is possible to use ManageCat for your private network, as we provide a special controller for on-premise installation.

6. Do you have public available API for managing the service (ManageCat / Jelastic)?

Gurkan: As for ManageCat, currently we have rest API, if you want to register your Tomcat servers, we provide you the  API with configuration parameters so that you can use it for your registered servers.

Ihor: Talking about Jelastic, we have two kinds of APIs - private and public. Public includes everything you see in the UI, plus some additional features. As for the Private API, it  is available only for Jelastic Hosting Providers and Private Clouds.

7. Do you have a free trial period?

Gurkan: In ManageCat we provide free trial, so if you use Jelastic Platform and have an account there, you can easily create Apache TomEE/Tomcat server, and get 15 days of free trial.

Tetiana: Jelastic also provides free trial, that depends on the hosting service provider (from 14 days to one month or even one year).

Thanks to everyone who joined our webinar or looked through the provided recording. Now you can experience the installation process on your own - it takes just a few minutes and require no manual configurations. Like magic! And no need to worry about Tomcat or TomEE servers while ManageCat is looking after them 🙂
