Riemann exporter
Usage
You can launch the Riemann exporter this way (running the default powercap_rapl sensor):
scaphandre riemann
As always exporter's options can be displayed with -h
:
scaphandre-riemann
Riemann exporter sends power consumption metrics to a Riemann server
USAGE:
scaphandre riemann [FLAGS] [OPTIONS]
FLAGS:
-h, --help Prints help information
-q, --qemu Instruct that scaphandre is running on an hypervisor
-V, --version Prints version information
OPTIONS:
-a, --address <address> Riemann ipv6 or ipv4 address [default: localhost]
-d, --dispatch <dispatch_duration> Duration between metrics dispatch [default: 5]
-p, --port <port> Riemann TCP port number [default: 5555]
With default options values, the metrics are sent to http://localhost:5555 every 5 seconds
Use -q or --qemu option if you are running scaphandre on a hypervisor. In that case a label with the vm name will be added to all qemu-system*
processes.
This will allow to easily create charts consumption for each vm and defined which one is the top contributor.
Metrics exposed
Typically the Riemann exporter is working in the same way as the prometheus exporter regarding metrics. Please look at details in Prometheus exporter documentations.
There is only one exception about process_power_consumption_microwatts
each process has a service name process_power_consumption_microwatts_pid_exe
.
As an example, process consumption can be retrieved using the following Riemann query:
(service =~ "process_power_consumption_microwatts_%_firefox") or (service =~ "process_power_consumption_microwatts_%_scaphandre")
