Twice the number of nodes on "Docker Engine Info" table #117

Closed baskinsy closed 4 years ago

baskinsy commented 4 years ago

Hello,

Maybe I'm missing something but I have seen this on multiple installs. In the example I have a 6 node (3 managers + 3 workers) swarm cluster and although grafana reports correctly 6 nodes, in Docker Engine Info table there are 12 (see attached image). The same happens on Cluster members table. Executing docker node ls reports 6 matching IDs with the table. I suspect that this may have to do with a leader swarm node re-election after restarting docker daemon on the leader node but it is just a guess.

Any hints or any idea how to look further?

Cheers

I made my own grafana image based on v5.4.5 and the issue was resolved, don't know if it was a coincidence but I'm closing this. In any case grafana v5.4.5 seems that works ok so you can update it.
