Hello. I have failed periodic job. How can I find all logs for periodic jobs?
If I run nomad status jobname
username@host1:~$ nomad status jobname
ID = jobname
Name = jobname
Submit Date = 2022-10-11T11:53:20+03:00
Type = batch
Priority = 50
Datacenters = DC
Namespace = default
Status = running
Periodic = true
Parameterized = false
Next Periodic Launch = 2022-11-29T02:30:00Z (16h58m38s from now)
Children Job Summary
Pending Running Dead
0 0 50
How can I get all logs from the last and previous jobs?
Thank you!
When periodic job have been triggered and not yet garbage collected, the child job executions should be found under a heading named “Previously Launched Jobs” on the CLI when detailing the parent job.

If this section is missing or does not contain any job listings, it is most likely because the child job data has been garbage collected. Nomad periodically cleans its internal state of job, allocation, evaluation, and node data to keep the server memory footprint as small as possible.
In order to store and view logs for Nomad jobs, log shipping is expected. This is where the logs are taken from the Nomad client and exported to a storage source such as Loki. There are some Discuss posts which talk about this topic; the nomad-autoscaler horizontal scaling demo also includes example log shipping to Loki that could be used as reference.
