Searching Kinsta’s Access Logs for Issues

Kinsta allows for SSH and searching through your access logs. Here’s a few snippets that allow for searching through your access logs to find issues.

You’ll notice that all the requests start with cd /www/*/logs &&. This will automatically navigate to where the access logs are. If you’re using this on another platform, you may need to edit or remove this. While the guide here is specific to Kinsta, the commands can be altered for searching anywhere as they are generic Linux search commands. Note that Kinsta only keeps access logs for four days. If you’re looking for data past that, you can recover from a backup into your staging environment.
