## Problem/Question On one linux server from many I’m getting insane results for softirq latency. On top of that it provides value every so often not like every second or minute… ![image](https://canada1.discourse-cdn.com/flex029/uploads/netdata2/original/2X/2/23f089e55758148ffde99870e58ac4f2851899a7.png) ## Relevant docs you followed/actions you took to solve the issue ## Environment/Browser/Agent’s version etc Linux, v1.38.0-18-nightly, Chrome ## What I expected to happen Something like this: (Taken from another node) ![image](https://canada1.discourse-cdn.com/flex029/uploads/netdata2/original/2X/5/54a68ba2a4ef7eec0cd2f92cc2e9abe5dfb2479d.png) ---

Hello @ben , Do you have messags like these ```auto "Cannot read /proc/softirqs, zero lines reported." "PLUGIN: PROC_SOFTIRQS: Cannot find the number of CPUs in /proc/softirqs" ``` inside your `/var/log/netdata/collector.log`? If you do not have, can you share with us the output of the command ```auto grep -w proc /var/log/netdata/collector.log ``` ? If you prefer you can send an email for thiago@netdata.cloud. The fact that this is happening with only one host indicates issues to collect data for this host. We also expect do not deliver more charts like this, because the issue was already fixed with PR [do not report dimensions that failed to be queried by ktsaou · Pull Request #14447 · netdata/netdata · GitHub](https://github.com/netdata/netdata/pull/14447). Best regards! ---

But I have it! on 2 nodes.(because I can see plenty of information in connection tracker like search restart and e.t.c) And both of these nodes have bug mentioned in this topic. ---

Hello @ben , Sorry for the delay to answer. Thank you for the output. The logs are not showing any error from the thread that collects data. The errors from `grep -w proc` are showing errors that are probably from `apps` or `ebpf` that tries to parse these files. Now about `nfacct` plugin, I will let @Austin_Hemmelgarn to speak about, because in normal situation I always compile netdata from scratch. The association between `nfacct` and error was not something that I thought initially, but I cannot discard completely, because there is a relationship between IPTABLES (Netfilter) and softirq. @Austin_Hemmelgarn is it possible to run a `rpm SOMETHING` or `dpkg SOMETHING` that shows relationship between netdata packages and dependencies? @ben are you using netdata official repo? Or did you get netdata from dist repo? Best regards! ---
