Clone this repo +2. Install collectd + +.. code:: bash + + $ sudo apt-get install collectd + +3.

It can be IP address or hostname of VES collector +(default: `127.0.0.1`) + +**Port** *port* +* VES port (default: `30000`) + +**Path** *"path"* +* Used as the "optionalRoutingPath" element in the REST path (default: `empty`) + +**Topic** *"path"* +* Used as the "topicName" element in the REST path (default: `empty`) + +**UseHttps** *true|false* +* Allow plugin to use HTTPS instead of HTTP (default: `false`) + +**Username** *"username"* +* VES collector user name (default: `empty`) + +**Password** *"passwd"* +* VES collector password (default: `empty`) + +**FunctionalRole** *"role"* +* Used as the 'functionalRole' field of 'commonEventHeader' event (default: +`Collectd VES Agent`) + +**GuestRunning** *true|false* +* This option is used if the collectd is running on a guest machine, e.g this +option should be set to `true` in this case.

In this case the hostname in event message will be represented as UUID +instead of system host name. + +LoadPlugin uuid + +If custom UUID needs to be provided, the following configuration is required in collectd.conf +file: + +.. code:: bash + + <Plugin uuid> + UUIDFile "/etc/uuid" + </Plugin> + +Where "/etc/uuid" is a file containing custom UUID. + +Please also ensure that the following plugins are enabled: + +.. code:: bash + + LoadPlugin disk + LoadPlugin interface + LoadPlugin memory + +VES plugin notification example +------------------------------- + +A good example of collectD notification is monitoring of CPU load on a host or guest using +'threshold' plugin. The following configuration will setup VES plugin to send 'Fault' +event every time a CPU idle value is out of range (e.g.: WARNING: CPU-IDLE < 50%, CRITICAL: +CPU-IDLE < 30%) and send 'Fault' NORMAL event if CPU idle value is back to normal. + +.. code:: bash + + LoadPlugin threshold + + <Plugin "threshold"> + <Plugin "cpu-aggregation"> + <Type "percent"> + WarningMin 50.0 + WarningMax 100.0 + FailureMin 30.0 + FailureMax 100.0 + Instance "idle" + Hits 1 + </Type> + </Plugin> + </Plugin> + +More detailed information on how to configure collectD thresholds(memory, cpu +etc.) can be found here at +https://collectd.org/documentation/manpages/collectd-threshold.5.shtml |
