However, if I restart the service, the new geovent definition is initially missing so I can't configure the field mapper, until new data is received from the input. In my real world example, it can take some time until new data is received (consider e.g. a field mapper after an incident detector) and the geoevent gefinition is created, making it impossible to work on the field mapper processor or check if the service is working correctly.</P><P></P><P>Would it be advisable to create a "static" geoevent definition for the field mapper (e.g. a copy of the new defintion when the service is running), or is there a better way to deal with the issue of temporarely existing definitions?</P></BODY></HTML> Mon, 18 May 2020 12:35:04 GMT https://community.esri.com/t5/arcgis-geoevent-server-questions/issue-with-missing-geoevent-definition-when/m-p/651891#M2891 TimLeefmann 2020-05-18T12:35:04Z Re: issue with missing geoevent definition when restarting service https://community.esri.com/t5/arcgis-geoevent-server-questions/issue-with-missing-geoevent-definition-when/m-p/651892#M2892 <HTML><HEAD></HEAD><BODY><P>Hey <A href="https://community.esri.com/migrated-users/407032">Tim Leefmann</A>‌</P><P></P><P>Long story short, best practice is to create a GeoEvent Definition&nbsp;with/for your output first, field map into that definition before the field calculator, then field calculate into an existing field.</P><P></P><P>Some of the details behind the 'why' is contained in the following blog article:&nbsp;<A href="https://community.esri.com/people/eironside-esristaff/blog/2020/01/07/geoevent-consuming-new-data">https://community.esri.com/people/eironside-esristaff/blog/2020/01/07/geoevent-consuming-new-data</A>&nbsp;</P><P></P><P>Basically, if you have the Field Calculator create the GeoEvent Definition, this definition is transient and created/destroyed at the platforms whim.&nbsp; Whenever possible create GeoEvent definitions that are owned by your user and can't be deleted by the system.&nbsp; Field Map first, then use the existing fields whenever posssible.</P><P></P><P>Best,&nbsp;</P><P>Eric</P></BODY></HTML> Tue, 26 May 2020 19:11:39 GMT https://community.esri.com/t5/arcgis-geoevent-server-questions/issue-with-missing-geoevent-definition-when/m-p/651892#M2892 EricIronside 2020-05-26T19:11:39Z
