I've figured out what was going wrong with my job (by redirecting the output to a file). It couldn't verify the remote host's certificate: urllib2.URLError: Now to figure out why. I have nss-certs in my system packages. Best, Jack
Debugging an mcron job
Hi Guix, I'm looking for help or tips on debugging an mcron job. My goal is to run a site-specific telemetry script that I have packaged [0] in my channel. The script collects some information and sends it to a remote server. I am trying to run the script as an mcron job via a service I created in my channel [1]. [0] https://gitlab.oit.duke.edu/jackhill/guix-at-duke/blob/0ed0a8e7530ef32b9e268d43b36944e38defa5f1/guix-at-duke/packages/endpoint-management.scm#L98-140 [1] https://gitlab.oit.duke.edu/jackhill/guix-at-duke/blob/0ed0a8e7530ef32b9e268d43b36944e38defa5f1/guix-at-duke/services/endpoint-management.scm So far, this looks good, and after pulling my channel, reconfiguring, and restarting mcron, I can see my job in herd schedule mcron: """ # herd schedule mcron Tue Mar 12 00:51:00 2019 -0400 /gnu/store/61692zjpkhy3jqv4a7jk1k8a14k6yn8k-planisphere-report-0-0.1b606af/bin/planisphere-report … """ However, this doesn't appear to work because after the appointed time, the remote server is not updated. If I run the planisphere-report command by hand, the remote server is updated. If I replace the planisphere-report command in my job with "/run/current-system/profile/bin/touch /tmp/test-file", test-file is indeed touched, so I know that the jobs are running. Being fairly new to Guix, and extremely new to mcron, I don't know how to debug further. Are jobs run in such a way that they don't have network access? How can I see any errors or output? Best, Jack P.S. I'm happy to accept any comments about how to improve the code in my channel as well ☺.
