Purpose  

The purpose of this document is to provide a procedure to rectify the issue with availability report ("availability over time" shows up as empty when a pdf report is generated in 20.2 owing to bug 59749 - this is fixed in 20.2.3

Procedure

On the "shell" prompt of the analytic node, go to the below directory

sudo su

cd /opt/versa/var/van-app/templates/reporting/

ls -lrt

Open the file default.html through vim editor

vi default.html

Check if the below three lines are present

For ex, in the below default. html we dont see libs/highcharts-more.js

Below we've added the missing line as seen 

Save the above file 

Now go to "libs" directory

If highcharts-more.js file is missing, download the file (attached to this KB) and copy it to this location

Now check if all the .js files have v5.0.14 using "grep -i "v5.0.14" *.js

If highcharts.js does not show up in the list above - please download highcharts.js from the KB attachment and copy it to this location

Now try generating "site availability over time" report

Generate a PDF report and confirm if the report shows up fine as seen below
