Description sthirugn@redhat.com 2019-04-26 15:07:25 UTC
Description of problem:
Satelllite Audits page is very slow

Version-Release number of selected component (if applicable):
Satellite 6.4.2

How reproducible:
Always

Steps to Reproduce:
1.Navigate to Satellite UI -> Monitor -> Audits page.

Actual results:
It took 37 seconds to load this page. (production.log postgresql.log attached)
/var/log/foreman/production.log:
2019-04-26T10:57:42 [I|app|97741] Completed 200 OK in 37373ms (Views: 265.2ms | ActiveRecord: 15229.5ms)

# head audit
{
  "total": 5136427,
  "subtotal": 5136427,
  "page": 1,
  "per_page": 30,
  "search": null,
  "sort": {
    "by": null,
    "order": null
  },

Note:
- The response time increases with the number of audit entries. In the above example, I had 5.1 mill entries.
- The response time also increases in a production satellite with live traffic, the satellite I used had zero client production traffic.

Expected results:
Audit page should load faster

There are a couple of queries that make this call slow. I will try to outline my findings and possible solution where I can:

1. SELECT DISTINCT "audits"."auditable_type" FROM "audits"; 

Takes 2/40s

/usr/share/foreman/app/controllers/application_controller.rb:227:in `resource_base_with_search'

Can be mitigated by adding an index on auditable_type to audits table.

2. SELECT "audits"."id" FROM "audits"; 

Takes 3.5/40s (for the query only, I didn't measure Ruby time)

/usr/share/foreman/app/controllers/application_controller.rb:227:in `resource_base_with_search'

taxonomix.rb#taxable_ids should be refactored to something more restricted than bringing all ids from the table to memory.

3. SELECT audits.id FROM "audits";

Should be part of refactoring from #2 / caching of the ids.

This is the actual query that should remain even after the refactorings. Its Ruby times are not big too, since it starts from 31-st second out of 40.
