The canonical graphite implementation will read and discard NaN values
instead of throwing an error when reading on the line receiver protocol.
Since this is the default behavior for graphite, InfluxDB should have
the same behavior for compatibility.
Previously, a NaN value would result in an error printed to the console.
When you have a large number of NaN values being sent every minute, this
results in the log file filling with useless messages.
Float values are not supported in the existing engine and the tsm1
engines. This changes NewPoint to return an error if a field value
contains a NaN field. It also allows us to validate fields to prevent
other unsupported types from sneaking in through other input plugins.
Provides a little more flexibility in controlling the parsed
metric names for metris like:
servers.localhost.cpu.cpu0.user
Previously, you could only use a single field like "cpu", "user"
or a wildcard to match "cpu.cpu0.user". You can now pull out "cpu"
and "user" and join them together in the metric name using a custom
separator character. By default this is ".".
This adds a sorted search tree for matchining filters to a template
more efficiently. Each filter is split on "." and each element is
added to the tree. Patterns with matching prefixes are added under
the same subtree.
These are tags that can be added at the template level. They
will override any global tags and any parsed tags with the same
name from the metric will override these.
This filter implementation is fairly naive and won't scale well
to large numbers of templates and filters. It will be replaced
with a trie-based approach in the future.
