Node Exporter Dashboard EN 20201010-StarsL.cn

Grafana v6.7.4/v7.2.0 + node_exporter 1.0.1 test pass

If you are using grafana 6.x, please download and edit the json file, replace table-old with table, and then import it into grafana.

【English version】Update 2020.10.10, add the overall resource overview! Support Grafana6&7,Support Node Exporter v0.16 and above.Optimize the main metrics display. Includes: CPU, memory, disk IO, network, temperature and other monitoring metrics。https://github.com/starsliao/Prometheus

【中文版】

• 基于Job分组的通用版：16098

• 基于ConsulManager自动同步版：8919

推荐使用【ConsulManager】来管理主机/MySQL/Redis与站点监控，自动同步云资源到Prometheus，更多惊喜！

【ConsulManager介绍】

• 应用场景1：如何优雅的基于Consul自动同步ECS主机监控

• 应用场景2：如何优雅的使用Consul管理Blackbox站点监控

• 应用场景3：如何把云主机自动同步到JumpServer

• 应用场景4：使用1个mysqld_exporter监控所有的MySQL实例

• 应用场景5：使用1个redis_exporter监控所有的Redis实例

Important update:

• Newly added data source variable origin_prometheus, taken from the external system label of Prometheus: external_labels can be used to support multiple scenarios where Prometheus accesses to VictoriaMetrics or Thanos and other third-party storage to use the remote_write method. (No value by default, the absence of this label in the indicator does not affect the use) VictoriaMetrics please use v1.42.0 and above versions, which fixed the problem of displaying the grafana table.

• Added the time interval variable interval, all graphs are associated with this variable, and the granularity of the graph can be adjusted by selecting the time interval as needed. Note that the scrape_interval prometheus.yml. If there are less than 2 values in the rate time interval, the graph cannot be displayed. When it is equal to 2 values, rate is irate.(The default time interval is set to 2 minutes. If your Prometheus scrape_interval is greater than 1 minute, the graph will not be displayed. Just choose a larger time interval.)

Compatibility Release Notes:

If you import the dashboard, you get an error:

Copy

Failed create dashboard model
Cannot read property 'Symbol(Symbol.iterator)' of undefined

Note that your grafana version is too low, does not support the new BAR GAUGE chart, it is recommended to upgrade to the latest version of grafana, or re-import version without BAR GAUGE:

Resource Overview Resource Details

Notes:

After import the dashboard, please click Dashboardsettings– Variables to set the variable in the upper right corner of the dashboard according to the actual situation。

The three variables:$job, $hostname and $node will be set and associated by default.

• $node takes the instance of node_exporter, ip:port format. Most queries are associated with this variable, please make sure it is valid.

• $maxmount is used to check the maximum partition of the current host. Normally can only obtain partitions of type ext.* and xfs by default.

【update】：

2020/10/10

1. The origin_prometheus variable removed ALL to solve the problem of no data after clicking the link in the summary table.

1. Added 5-minute load, TCP connection number, timewait number, and total number of hosts to the resource overview table, and removed paging.
2. Fixed the problem of links to resource details in the resource overview table.
3. Replace all irate to be rate, increased the time interval variable, and can self-control the graph granularity. For more details, please refer to the description of Important Update as above.
4. Added data source variables to support multiple Prometheus. For more details, please refer to the description of Important Update as above.
5. Modified the description of the resource overview chart. Move the mouse to i in the upper left corner of the table to view it.

2020/06/27
