Opened: Dec 19, 2017
Severity: 4-Minor

Symptoms

If a new blade joins and is announced to statsd, statsd stops updating all /var/rrd/bladeXcpu files especially if it did not have prior knowledge of the blade.

Impact

The RRD CPU Files are not updated, which impacts the graphs generated from these files.

Conditions

If statsd is restarted after the blade is disabled, or goes down, and after that the blade rejoins the cluster, the /var/rrd/bladeXcpu files stop updating (where X is the blade number).

Workaround

Execute the command "bigstart restart statsd" after the new blade has joined the cluster.

Fix Information

None
