Significance of "red" cache regions in the HQ Health plugin?
I was checking out the new HQ Health plugin console for the first time and I have a question. When viewing the information available on the "Cache" tab. Some of the "cache regions" are colored in red, and some are not.
What is the significance of the red-highlighted cache regions? Is this something that I should be concerned about?
Should I increase the cache size for these regions? If so, how do you change the cache size?
Also, what qualifies as a "larger environment"? The HQ Health plugin helpfully provides statistics on my environment: # Metrics collected per minute: 1726 # Platforms: 52 # Servers: 193 # Services: 1995 # Agents: 52
Well, 'larger' just means larger than the cache is configured to work well for. You obviously want to make sure your miss rate is fairly low.
If you'd like, go to the 'health' screen, click 'print' and copy-n- paste the section containing the ehcache diagnostics to this thread and I can go over it with you.
