Hi,
mk_oracle was missing in destination folder. After copying it there from server, it executed with following output:
/usr/lib/check_mk_agent/plugins] ./mk_oracle -t
<<<oracle_instance>>>
<<<oracle_sessions>>>
<<<oracle_logswitches>>>
<<<oracle_undostat>>>
<<<oracle_recovery_area>>>
<<<oracle_processes>>>
<<<oracle_recovery_status>>>
<<<oracle_longactivesessions>>>
<<<oracle_dataguard_stats>>>
<<<oracle_performance>>>
<<<oracle_locks>>>
<<<oracle_systemparameter>>>
<<<oracle_tablespaces>>>
<<<oracle_rman>>>
<<<oracle_jobs>>>
<<<oracle_resumable>>>
<<<oracle_iostats>>>
<<<oracle_instance>>>
<<<oracle_processes>>>
<<<oracle_asm_diskgroup>>>
Nothing seem to be detected. While Oracle version is below:
sqlplus -V | grep ^SQL | cut -d" " -f3 | cut -d"." -f-2
19.0
