This is a set of Grafana dashboards to be used with Prometheus and InfluxDB datasources for MySQL and system monitoring.
The dashboards rely on alias
label in the Prometheus config and on the small patch applied on Grafana 2.6.
- Cross Server Graphs
- Disk Performance
- Galera Graphs
- MySQL InnoDB Metrics
- MySQL MyISAM Metrics
- MySQL Overview
- MySQL Performance Schema
- MySQL Query Response Time
- MySQL Replication
- MySQL Table Statistics
- MySQL User Statistics
- Prometheus
- Summary Dashboard
- System Overview
- TokuDB Graphs
- Trends Dashboard
- [InfluxDB] 1h downsample
- [InfluxDB] 5m downsample
For trending dashboards to work you need to create the continuous queries in InfluxDB, see the instructions.
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 192.168.1.7
the excerpt of the config will be look like this:
scrape_configs:
- job_name: prometheus
target_groups:
- targets: ['localhost:9090']
- job_name: linux
target_groups:
- targets: ['192.168.1.7:9100']
labels:
alias: db1
- job_name: mysql
target_groups:
- targets: ['192.168.1.7:9104']
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 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
Enable JSON dashboards by uncommenting those lines in grafana.ini
:
[dashboards.json]
enabled = true
path = /var/lib/grafana/dashboards
If you wish you may import the individual dashboards via UI and ignore this and the next steps.
It is important to apply the following minor patch on your Grafana in order to use the interval template variable to get the good zoomable graphs. The fix is simply to allow variable in Step field on Grafana graph editor page. For more information, take a look at PR#3757 and PR#4257. We hope the last one will be released with the next Grafana version.
sed -i 's/step_input:""/step_input:c.target.step/; s/ HH:MM/ HH:mm/; s/,function(c)/,"templateSrv",function(c,g)/; s/expr:c.target.expr/expr:g.replace(c.target.expr,c.panel.scopedVars)/' /usr/share/grafana/public/app/plugins/datasource/prometheus/query_ctrl.js
sed -i 's/h=a.interval/h=g.replace(a.interval, c.scopedVars)/' /usr/share/grafana/public/app/plugins/datasource/prometheus/datasource.js
Those changes are idemportent and do not break anything.
git clone https://github.com/percona/grafana-dashboards.git
cp -r grafana-dashboards/dashboards /var/lib/grafana/
service grafana-server restart
Simply copy the new dashboards to /var/lib/grafana/dashboards
and restart Grafana.
Here is some sample graphs.
