Description Tomasz Torcz 2020-03-19 18:25:47 UTC

Description of problem:
After upgrading to 1.20.0 from updates-testing, data from python plugins is not stored. I have at least two plugins: hddtemp and sensors; the categories on web page do not appear.
I've tried debugging steps from Netdata wiki, but without any resolution. When I manually run python plugin (for example: sudo -u netdata /usr/libexec/netdata/plugins.d/python.d.plugin hddtemp debug) I see data being collected. But normally running netdata has no data.
I have no ideas how to debug further. What should I do?

Version-Release number of selected component (if applicable):
netdata-1.20.0-1.fc31.x86_64

Take a look in the error log: /var/log/netdata/error.log and see if there's anything related.

Comment 2 Tomasz Torcz 2020-03-21 15:24:49 UTC

Nope, nothing about problems in error_log:

# grep sensors *
error.log:2020-03-21 16:05:22: charts.d: INFO: sensors: is disabled. Add a line with sensors=force in '/etc/netdata/charts.d.conf' to enable it (or remove the line that disables it).

I've reported it upstream: https://github.com/netdata/netdata/issues/3697

Here is the correct link to github issue: https://github.com/netdata/netdata/issues/8451

Comment 4 Tomasz Torcz 2020-03-23 09:52:50 UTC

The problem was external. I have a CEPH cluster which is not fully healthy. 'ceph' plugin in netdata was hanging, being unable to communicate with the cluster. After disabling this plugin, everything works (I gather fixing the CEPH cluster would also clear this issue).

Sorry for the late, it's a little bit complicated for now.

Good news to know it's working again for you.
