MySQL Enterprise Monitor 8.0 Release Notes
The HTTP connection between agent and Service Manager has a
default timeout of 250 seconds for an attempted connection and 300
seconds for an established connection. It is possible to override
these values in bootstrap.properties by
adding the following parameters:
http-connect-timeout-ms=N: Where N is the number of milliseconds to wait before timing-out a HTTP connection attempt.
http-socket-timeout-ms=N: Where N is the number of milliseconds to wait before timing-out a HTTP socket read or write.
If set to zero (0), no timeout is defined. Negative values are not supported.
