Grafana has high CPU usage and high I/O
|Assignee:||J. Wienke||% Done:|
InfluxDB uses ~600% CPU for about 1 - 1/2 hours. Also there is a high I/O during this time (4-6MB).
Is this intended? I suppose it is self-optimisation of the database (e.g. index generation)... If so, can this be forced to happen only at night (eg. past 1 am)?
see here for an image of the usage (CSRA internal)

Basically we are limited by the integration between influxdb and grafana and the (in-) ability to use continuous downsampling queries. I have informally evaluated graphite as a different backend again and performance is much better here. Usable support is implemented in the master tree.
