collectd is a system statistics daemon that collects operating system performance metrics. collectd can be configured to stream data into ATSD via TCP or UDP protocol using the write_atsd plugin.

See the write_atsd plugin documentation for details.

Configuration

Edit /ect/collect.conf by replacing atsd_hostname with ATSD IP address or host name, specify protocol and port. Example

...
<Plugin write_atsd>
     <Node "atsd">
         AtsdUrl "tcp://192.0.2.106:8081"
...
     </Node>
</Plugin>
...

Description of write_atsd plugin options is provided below

Setting Required Description Default Value
AtsdUrl no Protocol to transfer data: tcp or udp, hostname and port of target ATSD server tcp://localhost:8081
Entity no Default entity under which all metrics are stored. By default (if setting is left commented out), entity is set to the server hostname. hostname
ShortHostname no Convert entity from fully qualified domain name to short name false
Prefix no Metric prefix to group collectd metrics collectd
Cache no Name of read plugins whose metrics are cached. Cache feature is used to save disk space in the database by not resending the same values. -
Interval no Time in seconds during which values within the threshold are not sent. -
Threshold no Deviation threshold, in %, from the previously sent value. If threshold is exceeded, then the value is sent regardless of the cache interval. -
StoreRates no If set to true, convert counter values to rates. If set to false counter values are stored without changes, for example, as an increasing integer number. true
