Palo 3020 dagger logs

mike.tinklepaugh — Fri, 29 May 2026 20:34:26 GMT

I've done a private reset to the palo, ive done a factory reset to the palo. After logging in, the command I try putting in is show interface all. comes back as server error: Error Occured: See dagger.log for information. I then type the command to view the dagger logs, "less /var/log/mp-log/dagger.log" same when i try using "tail" and I get a Invalid syntax. I am not in the configuration part just the main part right after you login?

Hi @mike.tinklepaugh ,

It sounds like you're running into a management plane process lockup. Also, the reason you are getting an 'Invalid syntax' error on the logs is because PAN-OS uses custom commands rather than standard Linux syntax.

Here is how you can view those logs and hopefully clear that server error:

To view the dagger logs correctly, run this command: less mp-log dagger.log (Alternatively, use tail follow yes mp-log dagger.log to watch it drop errors in real time).
Restart the management process: Since show interface all is throwing a server error, the management server daemon likely crashed. Try restarting just that process by running: debug software restart process management-server Give it a few minutes to completely reload, log back in, and test the interface command again.

If it still throws a server error after that, the active PAN-OS partition might be corrupted. You'll want to reboot the box, type maint during the boot sequence to enter Maintenance Mode, and trigger a clean factory reset/re-install from the advanced menu there.

If all else fails an RMA might be in order and you should reach out to support.

Cheers!

Your line 1 of code was correct, it did bring up the dagger log. Here is what its currently showing.

Hi @mike.tinklepaugh ,

Your logs are not showing a hardware failure (like a dead drive or bad RAM). Instead, it's a software/configuration sync error where a background management agent is failing to register properly during bootup.

PAN-OS uses a configuration agent (cfgagent) to talk to system daemons (sysd). The boot process is trying to set a runtime flag to say "dagger" (a cloud-management/telemetry component) is registered.

The FAILED: NO MATCHES string means the system configuration schema doesn't recognize that exact setting path. It’s a software mismatch or a corrupted runtime state database, not a broken piece of metal.

It says cfgagent register failed in try 1/25... 2/25... 3/25. The system will loop 25 times over several minutes hoping the dependent services finish starting up in the background.

If this screen just popped up, let it complete the 25 attempts. Sometimes the master daemon is just slow to initialize, and attempt 5 or 10 will suddenly succeed.

If it completes 25/25 and drops to a maintenance prompt or hangs, power-cycle the device completely to clear out the corrupted sysd runtime state.

If it loops continuously on every reboot, the software image or runtime configuration database has become corrupted (likely after an interrupted upgrade or power loss).

Intercept the boot sequence via the console cable to enter Maintenance Mode.
Run a Factory Reset or select a previous PAN-OS version to restore clean software functionality.

If a factory reset or a sysroot switch fails to resolve the loop, then open a TAC case for an RMA, but tech support will almost certainly ask you to try a factory data reset or a clean software reinstall via maintenance mode first!

Hope this helps !
