# Nginx and ALB Access logs queries

## Rank UserAgent strings over all Nginx and ALB logs

This query will characterize activity by UserAgent over ALB and Nginx logs. This can be useful in an investigation, if an actor has a known set of characteristic UserAgents.

```sql
SELECT
 useragent,
 sum(row_count) AS total_rows
FROM (

SELECT
 useragent,
 count(1) AS row_count
FROM panther_logs.public.aws_alb
WHERE p_occurs_between('2021-01-01', '2021-01-02')
GROUP BY useragent

UNION ALL

SELECT
 httpuseragent AS useragent,
 count(1) AS row_count
FROM panther_logs.public.nginx_access
WHERE p_occurs_between('2021-01-01', '2021-01-02')
GROUP BY httpuseragent
)
GROUP BY useragent
ORDER BY total_rows DESC
```
