No heap usage metrics when 5.7.x agent connects to 5.8.x cartridge
This is a known issue JEE-7811.The problem is that heap usage was a derived metric that we calculated using raw metrics…but instead in 5.8.x we are collecting it directly as raw metric. So the derived metrics are gone from the cartridge, hence the chart blank.
Derived metrics have been removed and the new 5.8.x agent collects the required data to show up. Please upgrade the required agents to 5.8.x
Workaround:If upgrade is not an option at this time, workaround is to make the same config changes on the 5.7.x agent side. (or compatible configs namespace in the cartridge).
The changed files are
On FMS,go to Administration|Agent|Agent properties and copy the above files from the JavaEE namespace and paste the same in JavaEE-Compatibility|5.7 namespace.
Please backup your current 5.7 configs before you copy the 5.8.1 configs.No appserver restart required
