Let me explain what i mean:
Telegraf sends data to influxdb via udp in this format (fe. disk):
disk,datacenter=XXX,fstype=tmpfs,host=HOSTNAME,path=/run,rack=1a
free=1495953408i,inodes_free=2051914i,inodes_total=2052602i,inodes_used=688i,total=1681494016i,used=185540608i,used_percent=11.034271084792252
1469520283896909617
disk,datacenter=XXX,fstype=ext4,host=HOSTNAME,path=/,rack=1a
free=96700481536i,inodes_free=6970042i,inodes_total=7282688i,inodes_used=312646i,total=117230362624i,used=20513103872i,used_percent=17.500619745226178
1469520283896966437
(multiple values per line)
It would be nice to have this format (separated values with tag path and
tak valuename)
disk,datacenter=XXX,fstype=tmpfs,host=HOSTNAME,path=/run,rack=1a,vname=free
value=1495953408i 1469520283896909617
disk,datacenter=XXX,fstype=tmpfs,host=HOSTNAME,path=/run,rack=1a,vname=inodes_total
value=2052602i 1469520283896909617
disk,datacenter=XXX,fstype=tmpfs,host=HOSTNAME,path=/run,rack=1a,vname=inodes_used
value=688i 1469520283896909617
and so on (one value per line)
I "need" this for grafana graphs - because in default scenario, i'm not
able to create graf with something like select * from disk and show all
values in one graph. I must select valuename from disk metric for each
valuename - some machines not sending all values, so there is hosts with
empty values in graph.
In the separated (and vname tagged) scenario - i will be able to create
graphs like: select mean(value) from disk .. group by tag path, ... and all
values sent by host will show up in one graph with one "select" statement,
or i will be able to create select mean(value) from disk where vname =~
("/^inodes_.*$/)... for inodes graph and so on.
It would be nice to have configuration option to set sending format of tags.
Something global or per metric?
SPLITVALUES={yes|no} (default no)
VALUENAMETAG=vname (tagname for splitted scenario)
Or is there another option which should i use to achieve same behaviour?
ps.
i have python script which fetch my old munin-nodes via telnet and send
their metrics in this separated vname/value way and creating graphs for all
hosts is very simple selects per graph. In the first version of my script -
i send data to influx in the "grouped" format and creating dash/graphs was
pain in the eye.
Thanks
