We have a database table where some of the application errors are logged. We would like dynatrace to read the table row values and take actions based on the read data. Can someone please let us know if that is possible ?
We are using the dynatrace managed instance.
Definitely not out of box without coding, but you can write a oneagent plugin to fetch data from database table and forward it into dynatrace. Currently it is a bit limited and requires python skills. Also it probably won't fit your case - you can push only numeric values (timeseries metrics) to dynatrace using this API.
Also it's not clear what actions you want to take. Since dynatrace does not allow to execute anything on monitored systems, you are limited to sending alerts/displaying notification out of dynatrace.
