/api/analytics call taking 45 seconds to respond

Support - Assistance technique

Hi ,

One chart in our custom DHIS app requires us to display the top 5 indicators for a specified data set section. These indicators are calculated as [data element value] / [sum of all data element values in the data set section]. We are using the /api/analytics to fetch all indicator values from dhis after which we are filtering out the top 5 values in our app to display it to the user

One of our data set sections has a little over 60 data elements and loading this chart is taking about 45 secs.

Is there any optimization we can do to make this call respond faster

Regards

HI Sandesh,

can you check that all indexes are present on the analytics tables? The number of indexes per table should be (no of cols - 3).

Please also post the SQL queries generated by analytics, you can find them in the tomcat logs.

regards,

Lars

Hi Lars ,

I see that all the indicators are present in the analytics tables.
