collectd. The data will be transmitted to an instance of InfluxDB: a particular time series database that associates to each data the time (coded in UNIX timestamp) in which the server received it. Podcast 314: How do digital nomads pay their taxes? In the process we are going to touch on configuring custom plugin, custom types in CollectD DB and then pushing this data to InfluxDB for Grafana to consume. In my case, the agent machine also uses Ubuntu 14.04. After installation edit /etc/influxdb/influxdb.conf , set: We defined input/output points and we’re ready for the collectd. At the first, we have to install CollectD in the agent machine. In order to be able to analyse every metric of our infrastructure, it is necessary to use a program capable of capturing statistics on the machines we want to monitor. Quite often is it found that this installation is not up-to-date and compatible with operating systems. By default, CollectD captures metrics on CPU, RAM, memory (on disk), network interfaces, processes, etc. In doing so, the data will not be redundant and there is no risk that other nodes will overwrite the information. You can leave the `RRDTool` to still provide volatile statistics on your OpenWRT Luci Statistics Interface. Let’s imagine we have several machines located in a number of continents. As collectd is natively available already via yum, you should be fine in that aspect.
