How to reconnect the primary ArcGIS Monitor agent to server

[TristanMcHardie]

After a string of issues, our distributor and Esri support recommended we reinstall ArcGIS Monitor and reconnect it to the existing Postgres database, which we've done.

However, because it was offline for several weeks, all the ArcGIS Monitor Agents were disconnected, including the "primary" one running with ArcGIS Monitor Server. I've reconnected the satellite agents but there appears to be no mechanism to reconnect the primary agent.

How should I go about reconnecting the primary agent?

@TristanMcHardie, 

A couple questions for you:

• After reinstalling Monitor, is the OS service running under the same account as before?
• Was the configuration store deleted or moved before you reinstalled?

Hi @GeoJosh,

Yes, it's running as the same account as before.

Our config store was corrupted so it was easier to reinstall. I do have a copy of that, though.

Hi @GeoJosh, any ideas? I'm guessing I need to manually fix the agent's API key somewhere in the config store and/or Postgres DB.

If you have a copy of the config-store, you should be able to restore it to "C:\Users\<MonitorServiceUser>\AppData\Local\ESRI\ArcGISMonitor\config-store-server". The important piece in the config store that needs to be restored in this situation is the AGENT_TOKEN, which is used to authenticate the agent with server.

Thanks @GeoJosh.

I'd already attempted to copy the AGENT_* lines from the old .env (as below) but, after restarts, this hasn't worked.

AGENT_DESCRIPTION=
AGENT_ID=1
AGENT_NAME=ARCGISMONITOR
AGENT_TOKEN=xxxxxxxxxxxxxxxx
AGENT_URL=http://localhost:30082/arcgis

What can I try next?

@TristanMcHardie,

It appears that this issue requires deeper troubleshooting than what we can do over the forums. Can you please open a support ticket for this issue?

Was there ever a solution found to this issue? I've just upgraded Monitor from 2023.1 to 2024.0.1 and installed the 2024.0.2 Monitor Agent on the same machine.

When I run the command prompt provided by the upgrade instructions (<Monitor Agent installation location>\bin\arcgis-monitor-agent.exe admin:system:register --server-url <https://monitorserver.domain.com:30443/arcgis> --username <user> --password <password> --agent-id <agent ID>), I receive the error "[ error ] E ROUTE_NOT_FOUND: Cannot POST:/arcgis/monitor/auth/token". For this username/password, I am using my Monitor main Admin account. Is that what I should be using?

When I go to the Register Component page in Monitor, I can see the machine, but it's listed as disconnected even though the Agent service is running on the machine.

@ThomasM I ended up needing to start from scratch. Fresh install, fresh database, and reregister everything. However, it seems you're looking at a different issue here.

Hi @ThomasM,

That's a really strange and specific error message to get on agent registration. Can we check to make sure the upgrade was actually successful on the AGM Server side? If you log into AGM Server and click your username in the upper-right, what version do you see reported?
