       types.db - Data-set specifications for the system statistics collection daemon collectd


         bitrate    value:GAUGE:0:4294967295
         counter    value:COUNTER:U:U
         if_octets  rx:COUNTER:0:4294967295, tx:COUNTER:0:4294967295


       The "types.db" file contains collectd's metric type specifications. Each line describes
       one metric type, which is called "data set" in collectd. Each line consists of two or more
       fields delimited by spaces and/or horizontal tabs.

       For example, the following defines two data sets, "bytes" and "total_bytes".

         bytes        value:GAUGE:0:U
         total_bytes  value:DERIVE:0:U

       The first field defines the name of the data set. By convention, data set names use lower-
       case alphanumeric characters and underscores ("_") only. Also by convention, if a metric
       makes sense both as a cumulative metric (e.g.  "DERIVE") and a non-cumulative metric (i.e.
       "GAUGE"), the cumulative metric gets a "total_" prefix. For example, "bytes" is a "GAUGE"
       and "total_bytes" is a "DERIVE".

       The second and each following field defines a named metric value, called "data source".
       New data sets with multiple data sources are strongly discouraged.  Each field is a colon-
       separated tuple of the data source name, value type, minimum and maximum values: ds-

       •   ds-name is, by convention, a lower-case alphanumeric string. If the data set contains
           a single data source, it is called "value" by convention. Data source names must be
           unique within a data set.

       •   ds-type may be DERIVE, GAUGE, or COUNTER. For historic reasons a type called ABSOLUTE
           is also supported, but its use is strongly discouraged, and it should not be used for
           new metric type definitions.

       •   min and max define the range of valid values this data source. Either or both may be
           unbounded, which is specified by providing "U" instead of a number. For cumulative
           metric values, min and max apply to the value's rate, not the raw cumulative metric


       The location of the types.db file is defined by the TypesDB configuration option (see
       collectd.conf(5)). It defaults to collectd's shared data directory, i. e.


       If you want to specify custom types, you should do so by specifying a custom file in
       addition to the default one (see FILES) above. You can do that by having multiple TypesDB
       statements in your configuration file or by specifying more than one file in one line.

       For example:

        TypesDB "/opt/collectd/share/collectd/types.db"
        TypesDB "/opt/collectd/etc/types.db.custom"

       Note: Make sure to make this file available on all systems if you're sending values over
       the network.
