Grpc error. You need to make sure network available and OAP server started.

[SevenBlue2018]

I checked the oap server that I did not find any error.


I do not know the reason.

[wu-sheng]

Check your ip and port binding.

[SevenBlue2018]

Check where?

[SevenBlue2018]

Agent connnect the oap server, ip and port is right.

[SevenBlue2018]

Originally everything is normal.When I have a problem the disk space is full, I emptied the es data and restarted it.Now The agent has the above problem.

[wu-sheng]

If you erased all es data, you need to reboot agents.

[SevenBlue2018]

Oh my god!!!

[SevenBlue2018]

I did the same thing in another environment, but the agent can send data normally without restarting.I do not know this is why?

[SevenBlue2018]

Agent did not restart.

[wu-sheng]

Hard to tell from my side. If you erased the metadata, reboot is required, unless in 6.3.0+ agent.

[SevenBlue2018]

ok, thank you!!!
