I am using Ganglia 2.5.6.I add some metrics with gmetric, and the new metrics are successfully shown on the GUI. I then click on the metric name from the pull down box, the data are shown correctly, but the new metric names disappear from the pull down box.
The URL shows: https://myhostname/ganglia/?m=mymetricname&r=hour&s=descending&c=unspecified&h= I remove "&c=unspecified" from the URL, the metric names reappear. Have anyone meet the same problem?
