On envoie une valeur aléatoire toutes les 10 secondes et on observe le résultat sur un dashboard grafana qui se refresh tout seul toutes les 10 secondes ;-)

for i in {1..60}; do line=$(echo "toto $(( ( RANDOM % 10 ) + 1 )) $(date +%s)"); echo $line; echo $line | nc -q0 localhost 2003; sleep 10; done

[07:27] < torkelo>| matejz: I have managed to get about 140~ bytes per measurement (ES) asyd
[07:27] < matejz>| and was thinking of using it for metrics as well aviau
[07:27] < torkelo>| which is 12x the size requirement of Graphite (12 bytes per measurement)

[10:16] < torkelo> | agree, if you store more than 100 000 metrics/s I think ES is not a good option. But for short term performance logging the new metric features for flat_white
percentile and moving average, etc are looking very good

Petite concurrence à Grafana pour le coup

Un screenshot d'un dashboard qu'il est bien

If you have lots of metric names that change (new servers etc) in a defined pattern it is irritating to constantly have to create new dashboards.

With scripted dashboards you can dynamically create your dashboards using javascript. In the folder grafana install folder app/dashboards/ there is a file named scripted.js. This file contains an example of a scripted dashboard. You can access it by using the url:

http://grafana_url/#/dashboard/script/scripted.js?rows=3&name=myName

If you open scripted.js you can see how it reads url paramters from ARGS variable and then adds rows and panels.
