Latency

Hello team,

Is there any reason why in kubernetes charts for latency (node/pods...) are empty? - the same case is visible in your demo.

How to get latency charts for kubernetes?

thanks

Hi,

please send the logs:

cd /home/lpar2rrd/lpar2rrd # or your LPAR2RRD working dir
tar cvhf logs.tar logs tmp/*txt tmp/*json
gzip -9 logs.tar

Send us logs.tar.gz via https://upload.lpar2rrd.com

OK, I will provide logs soon, but as I wrote - the same case is in your Demo - https://demo.lpar2rrd.com/?menu=2817960&tab=6 -> Containers Latency tab.

Hi,

we are collecting 'container_fs_io_time_seconds_total' from cadvisror. Description: "Cumulative count of seconds spent doing I/Os".

We ran some IO workloads in containers and compared node sysstat data with cadvisor. It seems 'container_fs_io_time_seconds_total' is in nanoseconds rather than seconds.

Fix is almost ready, we are testing it right now.

how is testing going?

IS the fix included in 7.90 release?

Pavel · July 2

no, data provided by the kubernetes API is weird, or better, it is wrong as per us, it would have to be fixed on the kubernetes side

mgregorc_p4 · July 4

OK, but is there any action plan? current charts are unfortunately useless.

Pavel · July 4

we know, but we do not know what to do, problem is not on our side, i.e. no any action plan
