general server slow-down: can't figure out the cause

Post by travis_farmer » 2017/03/26 11:54:53

I have been experiencing a general server slow-down, across the board (website access, ssh access, etc). I am not entirely sure if it is a network hardware problem, or something directly on the server.

here is a basic diagram of the pertinent network here (summarized):
http://tjfserver.ddns.net/basic_network_map.pdf

at some point, i will be moving the WiFi router to eliminate the "WiFi to Ethernet" adapter, and plug the Ethernet directly into the back of the router.

here is the results of getinfo.sh

#  This is the default, if you make this bigger yum won't see if the metadata
# is newer on the remote and so you'll "gain" the bandwidth of not having to
# download the new metadata and "pay" for it by yum not having correct
# information.
#  It is esp. important, to have correct metadata, for distributions like
# Fedora which don't keep old packages around. If you don't like this checking
# interupting your command line usage, it's much better to have something
# manually check the metadata once an hour (yum-updatesd will do this).

Note: This output shows SysV services only and does not include native

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

this started when i plugged the Hobby Server's second ethernet port (eno2) into the 24-port switch, in order to make use of the interface for a GitLab server (no longer running). after i removed GitLab, i disabled the interface, and unplugged the CAT5 UTP cable from it. but SSH still takes a long time to login, and respond. the website also takes a while to load, though i am unsure if it is the same externally.

Normally, i am about average at troubleshooting, but this one has me at a loss.
I will post the current running processes in a following post.

Thanks in advance for any help. :D

Do you need to be running the 4.9 elrepo kernel for some reason other than "it's a bigger number, it must be better"?
The future appears to be RHEL or Debian. I think I'm going Debian.

i think it was brought in by a "yum update", but to be honest, i don't know if it is required. should it be reverted back to a different version?

i'm not calling it solved yet, but there may have been a hijacker on my WiFi. i changed the password to a longer one, and after i got everything reconnected that was supposed to be connected, things seem to just fly now, all across the board. :D

I used to think one long password was good, but now i think a new one every few weeks may be a better thing.
Better to be safe than sorry.
I will still monitor things to see if they slow back down, but right now, it is quite fast, by comparison.

If you didn't intend to install it and a yum update brought it in then you have accidentally enabled the elrepo-kernel repo that is normally disabled by default. The kernel that CentOS ships (and tests with) is 3.10.0-something and will be for the life of CentOS 7.

i have reverted the kernel back :D

Code: Select all

== BEGIN rpm -qa kernel\* | sort ==
kernel-3.10.0-514.10.2.el7.x86_64
kernel-3.10.0-514.el7.x86_64
kernel-devel-3.10.0-514.10.2.el7.x86_64
kernel-headers-3.10.0-514.10.2.el7.x86_64
kernel-tools-3.10.0-514.10.2.el7.x86_64
kernel-tools-libs-3.10.0-514.10.2.el7.x86_64
== END   rpm -qa kernel\* | sort ==
I think it was when i tried to install GitLab from an external HOWTO. it brought in a bunch of non-CentOS repos.
Next time i install GitLab, it will be on a separate server, so as not to kill the website i already have running, using the HOWTO on the GitLab website, this time.
