Usage

Using the server events gauge

In order to make the server events gauge work, you need to add this line on top of already registered server scripts in fxmanifest.lua Replace prometheus with whatever your prometheus resource name is.

server_script '@prometheus/eventHandler.lua'

Add a new metric

--[[
 * @event prometheus:addMetric
 *
 * @param {string} type - The metric type, i.e. Gauge.
 * @param {string} name - The metric name.
 * @param {string} description - The metric description.
 * @param {function} cb - A callback function to update the metric with a method name (i.e. set) and a value.
]]
TriggerEvent("prometheus:addMetric", "Gauge", "fxs_gauge_example", "Gauge example.", function(cb)
    math.randomseed(os.clock())
    if math.random(0, 1) == 1 then
      cb("set", 42)
    else
      cb("set", 1664)
    end
end)

Using the Prometheus data in Grafana

We supplied a grafanaDashboard.json including a example Grafana dashboard to use. To use it refer to Grafana Documentation
