#influxdb

Hi all

I was wondering if anyone would be able to help me out with enabling logging on Telegraf. I see that there is a logrotate file that points to /var/log/telegraf/telegraf.log but I am not able to see how one enables logging to this location

I have tried with the -debug flag but no log file was generated

iirc quiet = false in the telegraf.conf

might remember wrong though

is there anything available for parsing a ResultSet (looks like JSON) returned by a python query?

I would want time as python datetime and my fields are floats

with 'top', is it normal to see about 18 influxdb processes running? the machine has 24 cores.

awallin__: are you using top or htop?

gunnar___: (Back to my problems with network traffic graphs) I have had a lot of problems with managing anything that has a number that grows over time, like network bytes/pkts in/out, I think disk IOs is another one. I've tried the derivitive functions but I just don't seem to be able to figure out how to put all the pieces together to make something that makes useful graphs.

gunnar___: I've tried cobbling together various examples I've seen in issues and the like, but still really struggle with it. Maybe it's more something that could be addressed with Grafana for a better UX, but just having something that works is where I'm stuck now.

Happily, the one problem I had where I couldn't get large spikes at the beginning and end of my samples to go away seems to have been fixed. I think that was a derivitive problem in influx with the first/last sample getting the full value.

Anyone know of any samples for how to graph telegraf network traffic?

maybe you're graphing the network traffic from a multiple hosts and thatswhy it doesn't make sense?

anettu: Hmm. Can't just get an overall network rate? Like the derivitive is applied after the sum, so wrap arounds freak it out or something?

anettu: I'm also having problems if I group by host. Right now my graphs are dominated by huge spikes that don't make any sense.

have you tried with fill(none)?

anettu: It has "fill(null)" in it.

SELECT derivative(last("bytes_recv"), $interval) FROM "net" WHERE $timeFilter GROUP BY time($interval), "host" fill(null)

yeah, exactly the same one works for me

anettu: Are you setting a "group by time interval"?

work with and without it
