I want to know how many people have visited a particular isssue in order to know its popularity( I can't trust on number of watchers of the issue) .Is there any way (JiraDB or anything) by which i can know how many people(just the count) have visited any particular issue.
The question can be modified like this : Top 10 mostly visited issues in a week or so.
Seb's earlier answer provides a possible solution for JIRA Cloud. I am not aware of any off-the-shelf product for behind-the-firewall installations of JIRA, and I do not believe that views are tracked anywhere in the JIRA database.
For behind-the-firewall instances, you could certainly write a script to parse the JIRA access logs (stored in $JIRA_HOME/logs/access_log*) to count issue accesses that way.
The JIRA access logs are stored in a format that is similar to the Apache access log format, so you just need to parse out accesses to individual issues by looking for URLs of the format "http://MYJIRA/browse/ABC-123".
