Connection failed (Internal SQL Monitor error) - SqlProcessSampler

Carol

Hi All / Redgate Support Team,
We encountered an alert error Connection failed (Internal SQL Monitor error) - SqlProcessSampler in our server. 
Exception : CultureNotFoundException
Exception message : Culture is not supported. (Parameter 'culture') 66577 (0x10411) is an invalid culture identifier.
It seems occurred every hour. We do not have this kind of error previously until we installed a custom metrics
(

OS Wait Time: Async_Network_IO(secs) 

Average IO stall

)
I am not sure whether is the custom metrics caused it or other reason. 
Please help and provide your insights if you have experienced before.

Thanks,
Carol

Hi Carol

Is this a newly added server, or has it just occurred on this instance that has been monitored for a whilst?
What is the collation of the system databases of this instance?

SELECT name, collation_name FROM sys.databases

Hi, thanks for your reply. we have been monitored it for quite some time.
After i installed the custom metric "Average I/O stalls" and "OS Wait Time: Async_Network_IO", then the server start receiving this error. 
The collation for the system databases is Japanese_XJIS_100_BIN2. However, some user databases collation are Japanese_Unicode_BIN2.



Thanks,

Hi Carol

I have been attempting to replicate this but have been unable to do so thusfar. Does this only occur when the custom metric is gathering from this machine?
