If Data Availability is used within a scheduled report for URL Categories, and there are gaps in data 
for any of the appliances, the following message is displayed at the bottom of the page: “

Some data 

in this time range was unavailable.”

 If there are no gaps present, nothing appears. 

If the percentage of uncategorized URLs is higher than 15-20%, consider the following options:

For specific localized URLs, you can create custom URL categories and apply them to specific users 
or group policies. These transactions will then be included in “URL Filtering Bypassed” statistics 
instead. To do this, see information about custom URL categories the online help or user guide for 
your Web Security appliance.

For sites that you feel should be included in existing or other categories, see 

The set of predefined URL categories may periodically be updated on your Security Management 
appliance, as described in 

. 

When these updates occur, data for old categories will continue to appear in reports and web tracking 
results until the data is too old to be included. Report data generated after a category set update will use 
the new categories, so you may see both old and new categories in the same report. 

If there is overlap between the contents of old and new categories, you may need to examine report 
results more carefully to obtain valid statistics. For example, if the “Instant Messaging” and “Web-based 
Chat” categories have been merged into a single “Chat and Instant Messaging” category during the time 
frame that you are looking at, visits before the merge to sites covered by the “Instant Messaging” and 

The URL Categories Matched section shows the disposition of 
transactions by URL category during the specified time range, 
plus bandwidth used and time spent in each category. 

If there are a large number of unclassified URLs, see 

Represents policy, port, and admin user agent blocking that 
occurs before URL filtering.
