Troubleshooting¶
When I start manager I get the following error:¶
There is another Flopsar Database Manager running. You cannot run another Flopsar Database Manager using the same license.This message means you are attempting to start a manager instance on a machine, which already has another manager instance running on. Either use another licence file or another machine.
Agent does not send any data to its database.¶
- Make sure, your agent has a database set in your manager instance.
- Verify that the agent has a configuration assigned.
All the above points can be verified by executing the command (please, refer to Managing Agents for details how to interpret the results):
$ fs2mgr get --target agents <manager_home>If the agent has a configuration and database assigned, verify whether the agent can establish a TCP connection to the manager. You can check it using only the agent file by running it with the test command line argument:
$ java -Dflopsar.id=MyAgent -Dflopsar.manager=MANAGER_IP:PORT -Dflopsar.home=AGENT_DIR -jar flopsar-agent-2.2.jar testThis command will attempt to connect to the specified manager server and wait for the response. If the connection cannot be established, verify your network configuration.
I see DROPPED in Parameters column in workstation¶
This means that instrumented JVM drops parameters due to memory pressure. Either, increase memory limits for your application or decrease instrumentation.
