It seems like Sybase agent has a hard limit of number of databases to be monitored, which is 50, because customer has Sybase servers that has more than 100 databases but Foglight only reports 50.
Is there a way to change some internal parameter to have Foglight Sybase agent monitor all databases rather than 50 databases?
The Max number returned for database by default is set to 50. This is control in the ASP of the property and is editable. You can change the setting and assess from there. Check under LIR_List_Dfit within the Limit Incoming Rows List section of the Sybase agent ASP
