Logs #

For one reason or another, it will be required to read the logs of an App from time to time. This section covers the command required to filter and display the output of your Apps.

An App must exist and be deployed before you can expect any logs to show up.

To display log entries for your App, run log.

setops -p <PROJECT> -s <STAGE> --app <APPNAME> log
2020-10-05 17:42:54 [output] Testlog
2020-10-05 17:42:54 [output] Testlog
2020-10-05 17:42:54 [output] Testlog
2020-10-05 17:42:54 [output] Testlog

The output of this command can be configured to your specific needs by adding additional flags.

To hide the source of the log entry e.g. [app] or [health-check] you can use the flag --no-source.

The --limit INT or short -n INT limits the output to a specific number of log entries. Valid values for n are 0 < n < 10000 und it defaults to 250.

With --follow or -f, SetOps continuously displays new log entries as they are created by the App.

Both flags can be combined in order to display the n latest log entries and then continue to show new log entries.

If only -f is used, n will default to 250.

# -n prints only the last n entries (defaults to 250)
setops -p <PROJECT> -s <STAGE> --app <APPNAME> log -n 2
2020-10-05 17:42:54 [output] Testlog

-f continously prints new log entries as they are created by your app:

setops -p <PROJECT> -s <STAGE> --app <APPNAME> log -f

In addition to the number of printed entries, you can also configure the time period of log entries you are interested in. Use --before 2020-09-11T12:00:00Z and --after 2020-09-11T12:00:00Z to limit the range. Please note, that the limits are exclusive. If you want to filter for all logs from 2021 for example, please use --after 2020 --before 2022.

# --before prints log entries that occured before the given timestamp
setops -p <PROJECT> -s <STAGE> --app <APPNAME> log --before 2020-09-11T12:00:00Z
2020-09-11 11:35:54 [output] Testlog
2020-09-11 11:58:44 [output] Testlog
2020-09-11 11:59:37 [output] Testlog
setops -p <PROJECT> -s <STAGE> --app <APPNAME> log --after 2020-09-11T12:00:00Z

The values of --before and --after can be specified in the following formats:

2020-09-11T15:04:05+01:00  # with +01:00 as timezone

You can filter the logs by the task ID if you provide --task ID. Use app:ps <APPNAME> to get the ID of currently running tasks.

setops -p <PROJECT> -s <STAGE> app:ps <APPNAME>

   ACTIVE 1 / 1 running tasks (0 pending)

SetOps will not print successful container Health Checks by default to prevent your Logs from becoming unnecessarily noisy. If you prefer to see these entries as well, you can force SetOps to print them with the flag --all-health-checks.
