Description (partial)


The Global Correlation sensor health metric shows as an unrealistically-high value number 
(approximately 1,266,503,800 plus seconds of device uptime). Since this value is greater than both 
the Yellow and Red Threshold values, the Global Correlation health metric shows as Critical (Red).

This can/will be observed via IDM and IME (IPS Manager Express) and the Red condition itself via 
the sensor's 'show health' CLI command output. 


Sensor running IPS 7.0 software on which Global Correlation has never successfully performed an 
update. By-default, 7.0 sensors (new installs and upgrades from prior versions) will not successfully 
update Global Correlation, as a requirement for such is to configure one or more valid DNS servers 
and (if the network environment makes use of a proxy) a proxy server.

As such, all 7.0 sensors will encounter this behavior until Global Correlation has successfully updated 
at least once.
