Statistics in collectd consist of a value list. A value list includes:
| Example | comment | ||||||
| Values | 99.8999 | percentage | |||||
| Value length | the number of values in the data set. | ||||||
| Time | timestamp at which the value was collected. | 1475837857 | epoch | ||||
| Interval | interval at which to expect a new value. | 10 | interval | ||||
| Host | used to identify the host. | localhost | can be uuid for vm or host… or can give host a name | ||||
| Plugin | used to identify the plugin. | cpu | |||||
| Plugin instance (optional) | used to group a set of values together. For e.g. values belonging to a DPDK interface. | 0 | |||||
| Type | unit used to measure a value. In other words used to refer to a data set. | percent | |||||
| Type instance (optional) | used to distinguish between values that have an identical type. | user | |||||
| meta data | an opaque data structure that enables the passing of additional information about a value list. “Meta data in the global cache can be used to store arbitrary information about an identifier” | ||||||
