Error: Not enough data collected to generate an availability report
Details
Why does the Availability Report page state Not enough data collected to generate an availability report?
Solution
The Availability Report is generated after scheduled tasks in the Service Console are completed. As these tasks are scheduled to be run daily, an entire day of operation may be necessary before the report is ready to be viewed in the Management User Interface.
You can manually execute the scripts that generate the report by issuing this command from the Service Console as the root user:
/etc/cron.daily/vmkuptimereport
Note: There is a known issue with ESX Server for systems that have '-' characters in their hostnames. This issue prevents the Availability Report from being generated. This problem has been solved in ESX Server 2.0 and later.
To workaround this issue if you have an earlier version of ESX Server installed:
Log in to the Service Console as the root user.
Edit the /usr/sbin/vmkuptime.pl file.
Look for the line:
if ($line =~ /^(\w+)\s*(\w*):\s+\((\d+)\)\s+(.*)$/)
Change this line to (the first w should be changed to an S):
if ($line =~ /^(\S+)\s*(\w*):\s+\((\d+)\)\s+(.*)$/)
Save the file and then run /etc/cron.daily/vmkuptimereport from the command line as described earlier in this article. The Availability Report should now be viewable in the Management User Interface.
