Server Logs

You can view log files within MyKinsta and download additional logs via SFTP. Log files cannot be manually cleared and are retained for up to 4 days. These files are valuable for troubleshooting errors and identifying other issues on your site.

View logs in MyKinsta

Three types of log files are available in MyKinsta: error.log, kinsta-cache-perf.log, and access.log.

1. In MyKinsta, go to WordPress Sites and select the site for which you want to view logs.
2. Click on the Logs tab to open the Log viewer page.
3. The first log file shown is error.log. Click on the dropdown menu where the log file name is shown to switch to another log file.

   

   

   

4. You can also use the search box next to the log file name to search for text in the current file.

Download logs with SFTP

In addition to the error.log, kinsta-cache-perf.log, and access.log files, you can also download your cache-purge.log and mail.log files using SFTP.

1. Connect to your site with SFTP.
2. Navigate into the logs folder/directory.
3. In that folder, you’ll find your log files. You can download any or all of these.
4. Once you’ve downloaded the log file(s), you can open any of those with your preferred text editor or import them into a log viewing application if you prefer. For files that are compressed (*.gz files), you’ll first need to unpack/uncompress those before opening them with a text editor.

Log file descriptions

For each log file type, the file without a date at the end of the name contains data for the current day. Historical logs from previous days are named with the date of the following day. For example, an access.log file named access.log-2022-07-25-1658707208 contains logs from just after midnight July 24, 2022, until just before midnight July 25, 2022.

The oldest 3 files are compressed and stored as *.gz files.

• access.log: This file is a log of Nginx requests for the current day.
• error.log: Specific errors, including PHP errors, are logged here.
• kinsta-cache-perf.log: Cache header status (hit, miss, or bypass) for requests are recorded here.
• cache-purge.log: This file contains a log of requests to cache clearing URLs (including cache clearing URLs configured in the Kinsta MU Plugin).
• mail.log: A record of the number of emails sent from your site each hour. Each line will look something like this: [22/Sep/2021:21:56:01 +0000] "H" 1 "no_action"
  • Format is: [time] "H" [count] "no_action"
  • “H” and “no_action” are constants that can be ignored.
