Dwane Hall created SOLR-15251:
---------------------------------
Summary: Metrics changes in Solr 8 cause admin dashboard to render
incorrectly
Key: SOLR-15251
URL: https://issues.apache.org/jira/browse/SOLR-15251
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Admin UI, metrics
Affects Versions: 8.8.1
Reporter: Dwane Hall
The metrics API appears to have changed between Solr 7 and 8. Some of the
effected metrics are used on the Admin UI Dashboard view resulting the view not
rendering correctly. The main culprits appear to be os.totalPhysicalMemorySize
not being calculated in Solr 8 and two missing metrics os.totalSwapSpaceSize
and os.freeSwapSpaceSize which are all used in the Dashboard view page.
Values memory.heap.committed, memory.heap.init, memory.heap.max also appear to
be using the identical value in Solr 8. Below is an extract of the javascrpit
used on the Admin Dashboard and a comparison between metrics reported in Solr 7
and 8. The function "parse_memory_value" is where the JavaScript error appears
to be thrown with the missing metrics.
