And use them in the prometheus output plugin.
Still need to test the prometheus output plugin.
Also need to actually create typed metrics in the system plugins.
closes#1683
1. in prometheus client, do not check for invalid characters anymore,
because we are already replacing all invalid characters with regex
anyways.
2. in win_perf_counters, sanitize field name _and_ measurement name.
Also add '%' to the list of sanitized characters, because this character
is invalid for most output plugins, and can also easily cause string
formatting issues throughout the stack.
3. All '%' will now be translated to 'Percent'
closes#1430
Adding precision rounding to the accumulator. This means that now every
input metric will get rounded at collection, rather than at write (and
only for the influxdb output).
This feature is disabled for service inputs, because service inputs
should be in control of their own timestamps & precisions.
if i understand the prometheus data model correctly, the current output
for this plugin is unusable
prometheus only accepts a single value per measurement. prior to this change, the range loop
causes a measurement to end up w/ a random value
for instance:
net,dc=sjc1,grp_dashboard=1,grp_home=1,grp_hwy_fetcher=1,grp_web_admin=1,host=sjc1-b4-8,hw=app,interface=docker0,state=live
bytes_recv=477596i,bytes_sent=152963303i,drop_in=0i,drop_out=0i,err_in=0i,err_out=0i,packets_recv=7231i,packets_sent=11460i
1457121990003778992
this 'net' measurent would have all it's tags copied to prometheus
labels, but any of 152963303, or 0, or 7231 as a value for
'net' depending on which field is last in the map iteration
this change expands the fields into new measurements by appending
the field name to the influxdb measurement name.
ie, the above example results with 'net' dropped and new measurements
to take it's place:
net_bytes_recv
net_bytes_sent
net_drop_in
net_err_in
net_packets_recv
net_packets_sent
i hope this can be merged, i love telegraf's composability of tags and
filtering
This will basically make the root directory a place for storing the
major telegraf interfaces, which will make telegraf's godoc looks quite
a bit nicer. And make it easier for contributors to lookup the few data
types that they actually care about.
