perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi George,

The error you are seeing is about the log permissions. Make sure the log files under /var/log/esmond are owned by the "apache" user then restart httpd. Did you copy over logs from the old host as well?

Thanks,
Andy

It appears that the existing user api key was overwritten during the migration process.  Running both

/usr/sbin/esmond_manage add_ps_metadata_post_user

/usr/sbin/esmond_manage add_timeseries_post_user

reveal that the Key was changed to the value in the old archive for the user.  Changing the auth-token

in the archives.d/*.json file on the testpoint servers didn’t help. I’m still getting HTTP  500 errors.

I attempted to migrate data from an older pS archive to one built on pS 4.1 by following these instructions.  Unfortunately once I had completed the migration none of my pS testpoint servers are able to post data into esmond. Now I’m getting Code 500 errors instead.

Thanks,

George
