After upgrade to 10.5 receiving several errors about a collection failure due to "Collection 'xxxxx' failed : Input string was not in a correct format."
解决办法
Known issue in version 10.5.0 (reference#SOSSE-3173).
1.Backup {Diagnostic Server directory}\agent\conf\Rule\SQLServer_SpotLight-LongRunningSQLRule.xml to another folder (not under program files). Just in case.
