This app provides a set of dashboards for MySQL performance and system monitoring with Prometheus datasource. The dashboards rely on alias label in the Prometheus config and depend from the small patch applied on Grafana.

Setup instructions

Import dashboards

Enable the plugin and import the necessary dashboards from plugin's Dashboards tab.

Add Prometheus datasource

The datasource should be named Prometheus so it is automatically picked up by the graphs.

Prometheus configuration

The dashboards use alias label to work with individual hosts. Ensure you have alias defined for each of your targets. For example, if you want to monitor the excerpt of the config will be look like this:

  - job_name: prometheus
      - targets: ['localhost:9090']
  • job_name: linux target_groups:

    • targets: [‘’] labels: alias: db1
  • job_name: mysql target_groups:

    • targets: [‘’] labels: alias: db1

Note, adding a new label to the existing Prometheus instance will introduce a mess with the time-series. So it is recommended to start using alias from scratch.

How you name jobs is not important. However, "Prometheus" dashboard assumes the job name is prometheus.

Also it is assumed that the exporters are run at least with this minimal set of options:

  • node_exporter: -collectors.enabled="diskstats,filesystem,loadavg,meminfo,netdev,stat,time,uname,vmstat"
  • mysqld_exporter: -collect.binlog_size=true -collect.info_schema.processlist=true
Apply Grafana patch

It is important to apply the following minor patch on your Grafana installation in order to use the interval template variable to get the good zoomable graphs. The fix is simply to allow variable in Step field of graph editor page. For more information, take a look at PR#3757 and PR#4257.

Run those 2 commands on top of your Grafana installation:

sed -i 's/expr=\(.\)\.replace(\(.\)\.expr,\(.\)\.scopedVars\(.*\)var \(.\)=\(.\)\.interval/expr=\1.replace(\2.expr,\3.scopedVars\4var \5=\1.replace(\6.interval, \3.scopedVars)/' /usr/share/grafana/public/app/plugins/datasource/prometheus/datasource.js

sed -i ’s/,range_input/.replace(/"{/g,"\"").replace(/}"/g,"\""),range_input/; s/step_input:""/’ /usr/share/grafana/public/app/plugins/datasource/prometheus/query_ctrl.js

Those changes are idemportent and do not break anything. No restart required.
