In Contrail version R3.1, a knob to stop the Analytics DB writes was introduced to reduce the Analytics load.
Customers can enable/disable the knob using introspect.
Use 'curl "http://<analytics-ip>:8089/Snh_DisableDatabaseWritesRequest?disable_all=1"' for old contrail versions.
Use 'curl "http://<analytics-ip>:8089/Snh_DisableDatabaseWritesRequest?disable_all=true"' for contrail versions 21.4 and later.
