How to use external tool to monitor that the application started successfully?
Our application run on 25 jvm nodes and sometimes we have to stop all node to do do some activity on servers. last time we found the issues that some nodes did not start property. User who accessed that node got error 403.
How do use external tool to check whether every nodes started perfectly? For now we have to go to SMA to check all 25 nodes. It would be great if we could monitor it faster than SMA.
Note: We don't have AES at this moment. Does AES help for our issue?
