Pull request overview
This PR fixes a bug in the ProxySQL go.d collector where backend status metrics were incorrectly mapped. The collector was comparing ProxySQL's string status values (e.g., "ONLINE", "SHUNNED") against numeric codes ("1"-"4"), causing all status metrics to incorrectly report as 0.
Key Changes:
- Updated status comparison logic to match string values instead of numeric codes
- Corrected test expectations to reflect accurate status reporting
- All four status states (ONLINE, SHUNNED, OFFLINE_SOFT, OFFLINE_HARD) now properly detected

| src/go/plugin/go.d/collector/proxysql/collector_test.go | Updated test expectations so status metrics now correctly show 1 when matched (instead of always 0) |

Summary
This fixes how the ProxySQL go.d collector derives per-backend
status_*metrics fromstats_mysql_connection_pool.ProxySQL returns status as a string (e.g.
ONLINE,SHUNNED,OFFLINE_SOFT,OFFLINE_HARD), but the collector was comparing it to numeric codes ("1".."4"), causing all status metrics to be reported as 0.Update the collector to set
backend_*_status_<STATE>based onvalue == <STATE>for the known states.Test Plan
