Hey @sailenderkumar16,

Please share additional info like what version of log monitor is this, your log monitor config and does this happen and no logs stream through or do you get some logs.

I've seen the error before when there's a read/write lock on the file such as when logs are rotating but it resolves and Log monitor is able to read the file.

Log monitor version: 1.2.1

Log monitor is able to get the logs and read it.But still it's getting the below error.

@TinaMor I have updated my ServerCore-based container to LogMonitor 2.1.1 and I can still see the old ERROR: Error in log file monitor. Failed to query file information. I'm afraid:
