State Queue Items

This important setting for the Health Manager sets the maximum size (in bytes) of the state data queue. If the value is too small or if there are too many workflows running (based on the number of objects being managed), there could be possible state change data loss. The default value for this setting is calculated by the Health Service on startup based on how many objects it needs to manage. For agents in a small environment, this value is set to 1024 (decimal). The value is set to 10240 (decimal) on management servers in a mid-size environment. For large environments, on management servers that manage many objects, the default is 25600 (decimal). The recommendation is to double these default values, depending on where it is needed—for an agent that manages a lot of objects or a management server.
