ADDM Findings Top SQL Statements

Question

Hi,
I have run addmrpt.sql for 1 month of time using snapshots and every ADDM report says that sql statement having id **** listed under top sql statements findings and recommendation is to tune using sql tunning advisor. It has 2-4 seconds elapsed time.But when i go through AWR report  instance efficiency report and all are normal.
Can anyone please confirm whether I should recommend to tune this SQL statement to my vendor ?
Thanks,
TK

Answer 1

below is the sql I found in ADDM. As I understood it is an intername SQL not an application SQL. When i searched it in internet found that it is related with check_oracle_health plugin. can you please help me to understand this nagios concept and the relationship it has with oracle software. And also how should I identify which methods we are using to monitor database internally?
