"使用 collectd + TDengine + Grafana 部署监控系统"

Question

Trying to construct a monitoring system. After using collectd to generate monitoring metrics into files with the following format, my next step will be importing data into TDengine and using Grafana as front end dash board to show collected metrics. What will be the best practice for converting such data format into TDengine compatible data format and import data into the database?

Answer 1

You can use collectd to write data into TDengine via taosAdapter.

Use "direct collection" way:

Modify the collectd configuration /etc/collectd/collectd.conf. taosAdapter uses 6045 for collectd direct collection data write by default.

LoadPlugin network
<Plugin network>
         Server "127.0.0.1" "6045"
</Plugin>

Or use "tsdb writer" way:

Modify the collectd configuration /etc/collectd/collectd.conf. taosAdapter uses 6047 for collectd tsdb write by default.

LoadPlugin write_tsdb
<Plugin write_tsdb>
        <Node>
                Host "localhost"
                Port "6047"
                HostTags "status=production"
                StoreRates false
                AlwaysAppendDS false
        </Node>
</Plugin>
